2019 Chevrolet Equinox Electrical Problems

Your car's forward collision warning system has repeatedly triggered false alarms and slammed on the brakes without any actual danger present, even while driving at highway speeds. When this happens, you also see warning lights for "service ESC," "service brake assist," traction control, and stability control. Your dealership found that four computer modules have outdated programming and need updates to fix the issue. This creates a serious safety risk since other vehicles behind you could hit you during the unexpected hard braking.

Your instrument cluster and driver information center display are completely blank, and the steering wheel controls aren't responding. Although your vehicle starts and runs normally, you can't see your speed, fuel level, or other gauges, and features like turn signals and headlights controlled from the steering wheel won't work. This likely requires diagnosis and repair of the instrument cluster wiring or the cluster itself.

Your tire pressure monitoring system (TPMS) stopped working at 49,000 miles and no longer alerts you when your tires are underinflated. The dealership quoted $732+ to fix it, but there's no active recall for your vehicle. Since this is a safety system required by federal law, you may want to contact Chevrolet or NHTSA about potential repair options. The fix will likely involve replacing the TPMS sensors or the TPMS control module.

Vehicle experienced derating. Check engine light on. Called mobile repair service. 20 year mechanic. Replaced Pedal Sensor. Fail. Second visit replaced Throttle Body. Fail. He advised better to take it to a reputable shop. Did. Shop worked on it for 2 months and ended up replacing ECM. I finally had the unit towed to an Electrical Specialist in Longmont Colorado. They replaced Wiring loom between pedal sensor and car worked again. Drove car to Kansas and after about 300 miles, loud boom and messages on display. ECM engaged electric emergency brake hard at 79 MPH. WAS on cruise. At 20 mph car stopped messaging, and resumed normal operation. Pulled over, checked car. 50 miles from nearest city. cautiously drove about 20mph, then 30, then more until up to speed limit again. Worked fine 140 miles (needed a population center to get car fixed)) and it happened again. Limped car a few miles to repair in Salina, Kansas. ECM erased all miles, messages, etc. They could find nothing. my research showed the 2025 Equinox EV recall (We had replaced ECM and reprogrammed). I went to get car and risked driving, but without cruise. Warnings would come up, but car ran. No more emergency stops, but plenty of warnings. $3K in repairs and still problem. I believe current problem is electrical that Equinox is known for. The ECM/Reprogramming problem that activated the Brake is the issue here and previously reported by many. Extremely dangerous! Car has 50K miles. Was flawless driver until now. Note: Unit was Rebuilt Salvage. I bought at 1460 miles. Hit right rear, Replaced right rear sheet metal, Rear driveline on right side (Genuine GM parts), Replaced Hatch door. Inspected by state of Michigan. Reputable Rebuilder. Zero bad reviews. Hundreds of excellent reviews. P.S. Cannot take to Chevrolet - they universally refuse to work on car - not to even change oil.

I was driving one day and my radio shut off, screen black and no sound. Came back on like it rebooted. Worked fine. The next day it did the same thing but only the screen went out but for longer this time. I work at a collision center and used our scanner to see what the problem might have been. It was giving a bunch of codes for radio and onstar. The next day it was perfectly fine. So I scanned it again just to see if the codes were still there. They weren't, but instead had 2 codes for brake control module in my engine and my transmission. My fan in the front has also been making slowing down and speeding up randomly.

Started off with my computer on my dashboard randomly turning off I called the dealership they told me it was because I was not using an iPhone Apple chord. Another instance I was driving down the road close to home and my car started stalling and flashing engine codes on my dashboard, I managed to make it home and park. The next day I tried to start my vehicle and it sounded like the battery was dead. I called a tow truck. The car had enough power for me to put it into neutral and get it onto the flatbed. My mechanic is less than 10 minutes away by the time they got it there they couldn’t do anything to move the vehicle. It had to be jacked up on the flatbed and rolled off because the car would not do anything My mechanic spent two weeks going through the computer system only to find out that I needed a software update and that my computer software had major glitches and electrical issues. Sometimes when I get into my vehicle to start it, it won’t start. I’ve learned that I need to put both feet on the brake. Push it all the way to the floor wait a second and then it will start otherwise my break seizes up and I’m locked out of my vehicle for at least an hour. This has happened to me on the side of highways in public parking lots in front of my home at the grocery stor. This past week I’ve had to get my car jumped 2 different times because when I turn my car off and lock it, my brake lights do not turn off and it killed my battery. I’ve had nothing but issues with the computer since day one from what I’ve googled this is a known issue with my make and model of vehicle. I contacted the dealership and they want to charge me thousands of dollars for something that was a factory defect.

I was driving down the road and my engine stopped. It stopped so suddenly that I did not have time to get out of the road and my safety was put at risk. When I took it to a certified Chevrolet dealership, they told me that the vacuum pump failure caused extensive damage to the motor and I needed to have my entire motor replaced. When I asked them what I could have done to prevent such catastrophic failure, they stated that there was nothing to prevent it. I did not have any warning on my dash at the time of the incident. This was at least the 2nd vacuum pump failure on this vehicle since I've owned it. I got it replaced at a certified Chevrolet dealership in 05/2022 when my brakes went out. In 05/22, the brakes went out but I was in a driveway and I did not feel my safety was a concern at that time. Now it's not even been 3 years and the vacuum pump failure risked my safety and caused catastrophic damage to engine to be replaced.

I JUST PURCHASED A 2019 CHEVY EQUINOX PREMIER AND I FOUND WATER IN THE SPARE TIME WHEEL WELL. AFTER SOME INVESTIGATION, I FOUND THERE IS A WATER LEAK CAUSING WATER TO SPILL ON THE FUSE BOX LOCATED IN THE BACK PANEL ON THE DRIVER'S SIDE. THIS IS CERTAINLY A SAFETY ISSUE IF THE FUSE PANEL SHORTS OUT, ESPECIALLY IF IT HAPPENS WHILE DRIVING.

The contact owns a 2019 Chevrolet Equinox. The contact stated that while at a complete stop at a traffic light, the engine Auto START/STOP feature engaged, and the engine turned off; however, upon depressing the brake pedal to resume driving, the vehicle failed to respond, rolled backward, and nearly struck another vehicle. The contact depressed the brake pedal several times and the vehicle stopped. There was a message indicating a power brake assist failure displayed. The contact stated that the failure had been recurring. The vehicle was taken to the dealer, where it was inspected, and the dealer confirmed that the vehicle was not designed with a button or switch to manually deactivate the engine Auto START/STOP system. The contact was charged a fee for the diagnostic test. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 88,000.

The contact owns a 2019 Chevrolet Equinox. The contact stated that the vehicle was experiencing an unintended opening and closing of the sunroof. The contact stated that the sunroof was opening and closing independently while driving and while the vehicle was parked and turned off with no keys nearby. The vehicle was taken to the dealer; however, the failure could not be replicated. The dealer contacted the manufacturer and was instructed on how to correct the failure. The dealer followed the manufacturer's instructions; however, the failure persisted. The vehicle remained at the dealer. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 57,500.

While driving the car cuts completely off while driving. Everything blacks out. No lights will come on, not even the emergency lights. It starts back up in about 15 to 20 minutes, lights come back on. And it starts back up. This has happened at least 3 times, almost causing me to get hit because when it shuts off it want roll or do anything else

The power liftgate (trunk) opens and then immediately closes, and tries to open again. I was in the back trying to get something out and the trunk started closing on me without me having pressed any buttons!! I tried to attach a video but it won’t let me.

As stated per Chevrolet of Flemington, “ Both rear door latches have actuators that are failing tested operation of rear door locks and found both rear door locks to be INOP preformed circuit checks and found to be ok. Found inside latches that the lock actuators have failed.” Basically, a few months back, the doors started to malfunction, and would either not lock, or not unlock. When I would put my car in drive and accelerate, the doors would not lock, which is a serious safety concern. When I tried to lock the doors, they would not lock, leaving the whole car accessible to stranger, and could have been stolen or hijacked by someone. The problem was confirmed by dealer and was fixed for $1500 dollars which is completely absurd as it is a safety hazard produced by their own car that is not even 5 years old. The vehicle was not inspected by the manufacturer or anyone else besides the dealership which eventually found and fixed the safety hazard. No, there were no warnings or other symptoms, and the problems first occurred back in October of 2023.

LCD screen as part of the infotainment system blanks out then repeatedly restarts. This goes for the entire drive. The GPS is not picking up the correct temperature and reports in Celsius not Fahrenheit. I'm not able to use any of the infotainment features including not being able to use the phone feature. Also the radio volume increases and decreases on its own. All of this is very distracting as I drive.

The car has constantly been stalling. The engine light comes on and goes off. These lights has come back on. This has been a reoccurring issue since the car was purchased in 2019. I just got the battery fixed this tear from them saying it was the battery. GM keeps offering me $2500 dollars but saying if I take it I can’t take action against them. That further let’s me know that they know something is wrong with the car.

Outside mirrors keep changing position. Almost got into crash because suddenly could not see while merging. This issue has been ongoing and many people are discussing the same issue on an Equinox forum.

Something is wrong with the brake assist system. The car was serviced literally towards the end of may and the brake assist service light keeps turning on. It is now causing the vehicle to have a check engine light that comes and goes as it pleases and the car now thinks that it is a bucking bronco at times with how hard it runs at times now. We have spoken and seen now multiple others complaining about the fueling system which does not alloe you to fill the gas tank up all the way. The tank holds 14.9 gallons and if the car is empty and on its last drop the car will only allow 12 gallons at best and that takes nearly 20 minutes of fighting with the car at the pump. The electrical in the vehicle is unstable. Multiple times while driving the radio and power to the car just turn off. I have also seen the recalls for the brake problems but when I enter my VIN it comes back all clear. We had a 2017 Chevy Malibu with multiple issues and spoke to Chevrolet about the issues and it wasn't until we traded it in that we started to receive the recall notices. This vehicle has some of the same problems and we have a toddler that we need to keep safe.

The contact owns a 2019 Chevrolet Equinox. The contact stated that both side view mirrors would not retain the adjusted settings upon start of the vehicle. The contact stated that the failure obstructed his vison while driving at various speeds. A local dealer was initially notified of the issue; but could not diagnose the failure. The manufacturer was then notified of the failure and referred him to another dealer. The vehicle was taken to White-Allen Chevrolet (442 N Main St, Dayton, OH 45405) on two separate occasions where both the actuator and the driver side arm rest switch were replaced; however, the failure persisted. The vehicle was not repaired. The failure mileage was approximately 40,000.

The contact owns a 2019 Chevrolet Equinox. The contact stated that the vehicle was able to be started without the key fob inside the vehicle. The key fob was at the contact's residence. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 23,071.

The car keeps shutting off at the light. I had to have it towed home. I have videos that I can’t upload here

The car was purchased February of 2019. The car has been stalling, car has shut completely down, and the car decrease speed sometimes while on the expressway which can be life-threatening. Not to mention that the radio freezes and the windows also gets stuck sometimes. It was reported to the car lot where the car was purchased as well as GM. the car was taken into Homewood Chevrolet where they stated that it was only a spark plug which is not true. I know that the car is having intermittent problems. They were suppose to an extensive check and I am positive that it was NOT done. There is an electrical and transit engine related issue that is not being addressed

i was traveling on cruise control at 60 mph when i clicked down to 55 mph at speed change. a couple minutes later the brakes slammed on hard enough to have the front wheels chirping i dont know if rear brakes came on but i went from 55 down to under 30 in a hard panic braking. this threw my wife up aganist her seat belt since she has had a stroke her resistanse to the hard slow down was low. i stepped on the gas and the brakes released i cant remember if i re engaged the cruise control or if it never disingaged. the other thing that happened was the warning about not using the info display while driving came up this only happens now and than when you start the car. so i suspect i had a momentary power lose in that circuit and what ever else is tied in to the info center im retired but i worked in mechanical engr all my life so i have some knowledge of systems

same errors codes i received less than 30 days ago when my car stopped while driving. This past 7/2/2021 my car stopped while in the mist of making a right turn.

Automatic engine shutoff did not restart at a busy stop light. Car shut down. Had to tow my car to auto repair. Computer code error U0284,B2575. Engine Stalls. Fixed the problem and 10 days later, I am driving and the car stops in the middle of the road again. Diagnosis is the same reason that the computer is not communicating with the car to start the engine.

TL* THE CONTACT OWNS A 2019 CHEVROLET EQUINOX. THE CONTACT STATED THAT THE HEADLIGHTS, THE ENGINE, AND THE ELECTRICAL SYSTEM FAILED TO OPERATE AS DESIGNED. THE CONTACT STATED THAT THE LOW BEAM AND HIGH BEAM HEADLIGHTS WERE AIMED INCORRECTLY. THE FAILURE TO ILLUMINATE THE ROADWAY PROPERLY CAUSED A DRIVING HAZARD WHILE DRIVING IN LOW LIGHT CONDITIONS. THE CONTACT WAS ALSO CONCERNED THAT AFTER STARTING THE VEHICLE AND WALKING AWAY WITH THE KEYFOB, THE VEHICLE SHUT-OFF INDEPENDENTLY. THE VHICLE WAS TAKEN TO DYER CHEVROLET (4200 SOUTH US HIGHWAY 1 FORT PIERCE, FLORIDA, 34982, (772)-461-4800) TO BE DIAGNOSED. THE CONTACT WAS INFORMED THAT THE HEADLIGHTS WERE NOT ADJUSTABLE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS CONTACTED AND INFORMED OF THE FAILURE. THE CONTACT WAS INFORMED THAT THE VEHICLE OPERATED AS DESIGNED. THE FAILURE MILEAGE WAS 10,300.

WHILE DRIVING HOME FROM WORK AT 9:30 PM ON A STATE HIGHWAY, MY 17 YEAR OLD SON HIT A DEER ON THE FRONT PASSENGER SIDE OF THE CAR. THE AIRBAGS DEPLOYED AND HE SLOWED DOWN AND PULLED OVER AND SMELLED SMOKE. HE GOT OUT OF THE CAR AND SAW FLAMES. HE IMMEDIATELY CALLED 911 AND HIS MOTHER. THE CAR WAS ON FIRE AND BURNED UNTIL FIRE COMPANY GOT THERE AND PUT THE FIRE OUT. MOST OF THE PASSENGER SIDE OF THE CAR UNDER THE HOOD WAS DESTROYED. THE CAR WAS A TOTAL LOSS. MY CONCERN IS THAT CAR SHOULD NEVER HAVE CAUGHT ON FIRE. MY SON IS LUCKY HE COULD GET OUT OF THE CAR. HE WAS SHAKEN UP AND GOT WHIPLASH FROM THE IMPACT BUT SEEMS TO BE OK. HOWEVER, MY BRAND NEW 2019 EQUINOX IS NOT OK. I CAN TELL YOU, IF THE CAR HADN'T STARTED ON FIRE, STRUCTURALLY, THERE WASN'T A TON OF DAMAGE. IT COULD HAVE EASILY BEEN REPAIRED. I WOULD LIKE TO KNOW HOW THIS HAPPENED?

TL* THE CONTACT OWNS A 2019 CHEVROLET EQUINOX. THE CONTACT STATED THAT WHILE DRIVING, THERE WAS AN ABNORMAL CHEMICAL ODOR INSIDE OF THE VEHICLE, COMING THROUGH THE AIR VENTS WHILE THE AIR CONDITIONER WAS ACTIVATED. THE FAILURE WAS PRESENT AFTER THE AUTO FUEL SHUT OFF WAS ACTIVATED AND THE VEHICLE RESTARTED. THE VEHICLE WAS TAKEN TO PRESTON HOOD CHEVROLET LOCATED AT 212 SW HOLLYWOOD BLVD, FORT WALTON BEACH, FL (850) 664-7000, HOWEVER, THE MECHANIC WAS UNABLE TO DETERMINE THE CAUSE OF THE FAILURE. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE, BUT OFFERED NO ASSISTANCE. THE FAILURE MILEAGE WAS 600.

THE ELECTRONIC SPEED CONTROL SUDDENLY STOPPED WORKING AND NO LONGER FUNCTIONS. THE AUTOMATIC STOP FEATURE CAUSES THE VEHICLE TO LURCH FORWARD SUDDENLY WHEN YOU PRESS THE GAS PEDDLE FOLLOWING A STOP. THE DYNAMIC BRAKING SUDDENLY ENGAGES WHILE DRIVING AT HIGHWAY SPEEDS ON THE INTERSTATE AND THERE ARE NO OTHER VEHICLES OR OBSTRUCTIONS IN THE AREA.

VEHICLE LOST ALL POWER WHILE PULLING INTO A 4 WAY MAIN ROAD. VEHICLE EMERGENCY LIGHTS/FLASHERS DID NOT WORK. COMPLETE ELECTRICAL FAILURE. CAR WAS STALLED IN ACTIVE TRAFFIC LANE DURING NIGHT TIME HOURS. VEHICLE WAS TOWED INTO DEALER FOR FULL DIAGNOSTIC REVIEW- NO ISSUE WAS FOUND WITH VEHICLE, ALTHOUGH SEVERAL EEC TEST CODES WERE DETECTED- P0627, P0629, P01400, U18A2, U1524 AND U18B4+71- MOST CODES HAVING TO DO WITH FUEL PUMP/EMISSION ISSUES. OWNER OF VEHICLE CONSIDERS THIS A SERIOUS ISSUE AS CAR STALLED AT NIGHT, IN A HEAVY TRAFFIC AREA WITH NO LIGHTING OR EMERGENCY FLASHERS WORKING TO PROVIDE PROTECTION FROM ON-COMING TRAFFIC. EMERGENCY PERSONNEL WERE CALLED TO ASSIST.

TL* THE CONTACT OWNS A 2019 CHEVROLET EQUINOX. WHILE DRIVING APPROXIMATELY 65 MPH, THE ADAPTIVE CRUISE CONTROL SHUT OFF AND THE "ADAPTIVE CRUISE CONTROL NOT AVAILABLE" INDICATOR ILLUMINATED. THE FAILURE RECURRED SEVERAL TIMES. THE VEHICLE WAS TAKEN TO DUNLAP MOTORS (866-715-7154, LOCATED AT 520 1ST STREET EAST, INDEPENDENCE, IA 50644) WHERE THE COMPUTER SYSTEM WAS REPROGRAMMED. THE FAILURE RECURRED AND THE VEHICLE WAS TAKEN BACK TO THE SAME DEALER WHO REPROGRAMMED THE COMPUTER AGAIN. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 2,000. *PM CONSUMER STATES EACH TIME FAILURE OCCURRED NO CARS WERE AHEAD OF THEM BUT THE VEHICLE WOULD BRAKE ABRUPTLY. ON 12/17/19 A MONITOR WAS PLACED IN VEHICLE BY THE MANUFACTURER, BUT THEY HAVE NOT HEARD ANYTHING BACK ABOUT IT. CONSUMER STATES THAT THEY HAVE ALSO EXPERIENCED ISSUES WITH THE PHONE, RADIO AND REAR DEFROSTER. THIS LEADS THEM TO THINK THAT SOMETHING IS WRONG WITH THE WIRING IN THE VEHICLE. *DL

THE INFOTAINMENT IN THE VEHICLE DOES NOT WORK PROPERLY. IT IS HIT OR MISS. EITHER IT WILL WORK AND I WILL NOT SEE ANY ISSUES OR IT WONT WORK. THE SOUND WILL NOT WORK WHICH THEN DOES NOT ALLOW FOR THE TURN SIGNAL NOISE TO WORK. THE AC FAN IS NOT SHOWING ON WHEN IT IS. THE SOFTWARE ON THIS DEVICE IS VERY GLITCHY.

IN MY VEHICLE OWNER'S MANUAL (PART NO. 84134729 B), THERE IS AN ERROR ON PAGE 352 WHICH MISIDENTIFIES THE POSITIVE AND NEGATIVE TERMINALS OF A BATTERY USED FOR JUMP STARTING. UNDER THE SUBTITLE, JUMP STARTING - NORTH AMERICA, THE TERMINALS NOTED AS (3) AND (4) SHOULD BE (4) AND (3).

TL* THE CONTACT OWNS A 2019 CHEVROLET EQUINOX. WHILE DRIVING 30 MPH, THE VEHICLE STALLED AND RESTARTED AFTER FORTY MINUTES. AFTERWARDS, THE SPEED WOULD NOT EXCEED 5 MPH AND THE CHECK ENGINE WARNING INDICATOR ILLUMINATED. THE VEHICLE WAS TAKEN TO CHEVROLET OF HOMEWOOD (18033 HALSTED ST, HOMEWOOD, IL 60430, (708) 251-4692) WHERE IT WAS DIAGNOSED THAT AN UNKNOWN WIRE WAS BURNED OUT. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE MILEAGE WAS 5,938.

THE AUTOSTOP FEATURE TURNED THE CAR OFF AND DID NOT TURN ON WHEN I PRESSED THE ACCELERATOR AND I WAS IN A INTERSECTION AND I WAITED FOR TEN MINUTES AND IT TURNED ON AGAIN. THE PROBLEM WAS WITH THE COMPUTER WHICH WASN'T WORKING.

THE VECHICLE'S ENGINE SHUTS OFF WHILE STOPPED FOR A VERY SHORT TIME ON ROADS IN TRAFFIC. IT CAN BE A MAJOR HIGHWAY, OR INTERSTATE AND EVEN NEIGHBORHOOD ROADS. IT CAN BE HAZARDOUS AS THE VEHICLE TAKES A MINUTE TO START BACK UP AND GET GOING. I HAD NO IDEA THIS FEATURE EVEN EXISTED, BEFORE I EXPERIENCED IT AFTER PURCHASING. I AM ALSO EXPERIENCING PROBLEMS WITH THE TAILGATE/TRUNK LOCKING. I LOCK THE VEHICLE, AND ALL DOORS LOCK EXCEPT THE TRUNK. I HAVE ONLY HAD THE VEHICLE SINCE DEC 31,2018 AND AM VERY SURPRISED TO BE EXPERIENCING THESE ISSUES SO SOON.

I AM UNABLE TO GAUGE THE TIME NEEDED FOR THE CAR TO RESTART AFTER "AUTOSTOP" SHUTS THE MOTOR AT A HARD STOP. THIS IS DANGEROUS FOR ALL DRIVERS AS EVEN WHEN LIFTING MY FOOT FROM THE BRAKE THE CAR DOES NOT MOVE AS IT SHOULD IN "DRIVE." INSTEAD, PLACING MY FOOT ON THE GAS PEDAL IS REQUIRED. THIS CAUSES UNEXPECTED DELAYS IN BEGINNING TO DRIVE THAT COULD HAVE SEVERE AND LONG LASTING CONSEQUENCES. I DO NOT AT ALL FEEL SAFE IN THIS VEHICLE. THIS HAPPENS BOTH DURING CITY AND HIGHWAY DRIVING, I.E. WHEN SITTING IN TRAFFIC. OTHER MANUFACTURERS HAVE A SWITCH TO DEACTIVATE "AUTOSTOP." CHEVROLET DOES NOT. I BELIEVE A MANDATORY RECALL IS REQUIRED TO REMEDY THIS CLEAR SAFETY OVER SITE.
