2025 Chevrolet Equinox Other Problems

Your vehicle has experienced water leaking inside the cabin, causing interior windows to fog up significantly during rainy, cold, or snowy weather—reducing visibility enough that you've had to pull over or use extreme defrost settings to see safely. You've also noticed mildew odors, damp seats, and the dealer found water-damaged carpeting and mentioned a known seal issue on this model, though you couldn't confirm an official recall by VIN. Beyond the water intrusion, you've experienced electrical and safety problems including infotainment screen failures, abnormal turn signals, lane-assist steering pulling the vehicle toward lane lines, and brake lockups during slow driving. The dealer is investigating whether a faulty door or window seal is causing the water intrusion and whether moisture damage is contributing to the electrical and safety issues.

Your panoramic sunroof suddenly shattered and scattered glass throughout the interior of your car while you were driving. This created a dangerous situation for you and your passenger. The manufacturer should investigate whether the glass itself is defective or if there's a structural issue causing the sunroof to fail. Repair will likely involve replacing the entire panoramic sunroof assembly and inspecting the frame for damage.

Your car's telematics control module (the system that handles vehicle connectivity) is draining your battery when the car is off. You've had the car since mid-February, it was towed to the dealer a week later, and nearly a month has passed without a resolution. Both the dealer and GM customer service have been unresponsive to your requests for help. The fix will likely involve the dealer diagnosing why the module is drawing excessive power and either reprogramming it or replacing the faulty module.

After your vehicle was hit by a deer and repaired, the battery kept draining even after you replaced it with a new one. The dealership has determined that your OnStar module needs to be replaced, but they can't give you a timeline for when the part will arrive. The repair will involve replacing the OnStar module, which the dealership says cannot be disabled.

You noticed your windshield was cracked after leaving a restaurant. The complaint doesn't indicate how the crack occurred or whether it affects your ability to see through the windshield.

Your OnStar communication module has failed, which disables your vehicle's OnStar services like emergency calling and remote features. The replacement part is currently on severe backorder, meaning there's a significant delay in getting a replacement available.

The onstar telematics module has stopped functioning. That means I am not receiving any systems updates, cannot use onstar, and cannot use the my Chevrolet app for remote start or remote unlock. I took it to the dealer 2 weeks ago and they said the telematics module is backordered. They did do a number of system updates. After those updates my adaptive cruise control has completely stopped working. When I called about that, the service department said that one module could have caused the other module to fail and that they won’t try to look at my cruise control until after they can replace the telematics. There is currently no ETA to receive the part.

Onstar module isnt working and was told to report it to you guys.

My Onstar module and Telematics is not working and Chevy/GM is trying to refuse to fix it and claim it's due to not having the Onstar internet plan. If that was the case it would never work, yet it works some days then other days it shows me in another city. My Google assistance will show not connected when Google maps doesn't work. I've only had this car since April 2025. This needs to become a recall. GM can't keep doing this to their customers.

I purchased my 25 Equinox in December 2024 and immediately started having issues. I worked with multiple dealerships when the issues began and then reached out to GM for further help. After more than 6 months of GM giving me the run around, I've been left with an unsafe vehicle that even they don't want back. I had no intention of trading the vehicle within the first 3 years, but I don't feel safe in this vehicle. When I left the dealership the day I bought it, the vehicle drastically depreciated once I cleared their mailbox and to this point, GM hasn't offered any assistance with offsetting my trade difference. I also got 0% financing with GM that isn't currently being offered if I were willing to take the massive loss on my trade in. Here are just a few of the issues that I'm dealing with. The blind spot warning light stays on for no reason. Multiple updates have been done, and modules were changed and the issue remains. At night the warning light shines right in my face. I've tried adjusting the mirror completely outward and it's still an issue. I try avoiding driving at night all together because it makes it very unsafe. If I do have to drive in the dark, I have to use my arm to try blocking the light from my face, but my arm isn't big enough to block all of it. The entire dash has gone black leaving me with no speedometer or gauges. It did come back on, and the dealership ran updates. Most recently, while driving the car will slam on the brakes and put the red triangles on the windshield for no reason. I've had vehicles behind me that almost hit me because it is a drastic drop in speed. Like brake checking. Sometimes the adaptive cruise will start slowing me down like when a car is in front of you only there's nothing there. Dealership doesn't have a solution for these issues. I've also been places and come back out to the car to find that the rear hatch has opened on its own. The dealership ran updates to hopefully prevent this from reoccurring.

I am submitting this letter to formally notify the NHTSA of a safety critical defect in my 2025 Chevrolet Equinox Activ starting on 12/9/25 involving the Telematics Control Module (TCM), GM part number 85669062. This defect results in intermittent or complete failure of essential OnStar safety functions, including Automatic Crash Response, emergency communication, and accurate GPS location reporting. During normal driving, the vehicle experiences the following failures: •Loss of telematics connectivity •Inability of OnStar services to initialize or maintain a connection •GPS location drift or inaccurate positioning •Failure to reliably transmit vehicle location or contact emergency services These failures occur without user action and under normal operating conditions. The defect directly impairs systems intended to provide crash detection and emergency communication. If a collision occurs, the vehicle may not contact emergency services or may transmit an incorrect location. This represents a loss of a safety system that General Motors advertises as part of the vehicle’s crash response capability. On December 9, 2025, my Chevrolet dealer confirmed that the Telematics Control Module had failed and requires replacement. General Motors has placed this part on national backorder with no estimated availability, leaving the vehicle in an unsafe condition with no available remedy. General Motors has not issued a recall, service bulletin, or customer satisfaction program addressing this defect. The absence of available replacement parts suggests a potential supplier level issue affecting multiple vehicles. Given the safety implications, part unavailability, and potential for a broader pattern of failures, I respectfully request that NHTSA: •Review this defect as a potential systemic issue •Evaluate whether similar failures are occurring in other GM vehicles •Consider opening a Preliminary Evaluation (PE) if warranted. Thank you.

Telematics unit in my Chevrolet equinox EV 2025 has failed. GPS/navigation/wifi does not work anymore. Calls to onStar for collision data / support in emergencies also do not work anymore. Also, basic features on the myChevrolet app to unlock/lock the car do not work. This happened gradually over time. Around 6 months after owning the vehicle, the GPS unit would sometimes randomly turn on/off and show my current location 1-2 miles away from my actual location. Then around 9 months after owning the vehicle, the unit as a whole failed and the whole tablet doesn’t work anymore. The dealer initially claimed that it was an issue with my onStar plan, but it is actually an issue with the telematics unit that needs to be replaced. This is a very well known problem is searched online across all newer GM vehicles that depend on Onstar.

I am the owner of a 2025 Chevrolet Equinox EV and have experienced ongoing and unresolved issues with the vehicle’s connectivity systems — including OnStar, internet access, GPS functionality, and over-the-air (OTA) updates. The problem first began in late July 2025, when I suddenly lost both internet connectivity and GPS navigation. During that episode, I was unable to use the OnStar system or navigation tools. Although the issue self-corrected after a few days, the instability raised concerns. The issue returned later in the year, and I visited my local Chevrolet dealer on November 24th, 2025, where a reset was attempted. While temporarily effective, the problem recurred. A follow-up service appointment on December 8th, 2025, confirmed that the Telematics Communication Control Module had failed — the same hardware component that controls OnStar access, vehicle geo-location, navigation, and software updates. At that time, I was informed by the service advisor that several other EVs were experiencing the same issue and that the replacement part was on national backorder, with some customers waiting more than two months. I was not given a clear estimate of when the part would arrive. This issue has effectively disabled: All OnStar connectivity (a paid subscription service), The vehicle’s ability to receive manufacturer-recommended OTA software updates, GPS navigation and location services, including vehicle tracking — a feature relied upon by my insurance company. Given the widespread nature of this issue, the lack of available parts, and the critical role of these systems in vehicle safety and functionality, I believe this constitutes a serious safety and consumer-protection concern.

Telematics Module failure. Vehicle is no longer able to provide GPS location. This is rendered all safety features and OnStar features for accident detection useless. Dealer states parts are on backorder with no ETA. Calls the GM result in no estimated ETA or part availability.

No component failures at this time. My dealer stated that the continued on/off of my check engine light is that of a " GM engineering flaw/ issue" without any remedy at this time. I have been advised to continue to drive the vehicle with check engine light on as no remedy is available at this time. The flaw was disclosed by GM in 4/2025, bought my vehicle in 6/25 - No remedy as of 12/12/2025 - This is more of an FYI than formal complaint.

Telematic Module System is malfunctions with a nationwide recall on the part. Chevy representatives have no date for when the part will be in. The computer system in the car is not working. I can't reach OnStar the internet I pay for doesn't work. My car has been in the service department for a month this year for the same problem and it's out again. Engineers from Chevy have worked on it as well. I need help with this situation. It's possible that the this failure could drain my battery causing it stop while driving. The service department and Chevy customer service just keep apologizing with no real dates on when this part will be in.

Unknown. The roof is separating along the groove line causing rust on my 2025 Chevy Equinox

when I started my car there was a very loud vibratory sound that caused my car to shake.When I accelarted the noise quite down but it was still there. When I stopped in traffic the sound reappeared. This occured for 2 hours ths length of my commute. When I made it to my destination. I lifted the hood. Idk what i was looking for. this morning the trembling is now light but the noise was not.

Our 2025 Equinox EV was leased new in March of 2025. Unknowingly, it had a water intrusion in the front passenger floor due to a manufacturing defect that GM is aware of. This is related to TSB 25-NA-149. The water intrusion was covered up and went unnoticed for some time due to the factory GM All-Weather floor liners. Once discovered due to the musky smell in the vehicle, black mold was found after pulling up the floor liner. The vehicle was inspected by a Chevrolet dealer, who confirmed it was due to a poor body weld that has now been resealed. Replacement carpet is on backorder due to many experiencing this defect. Our safety and the safety of others is put at risk since GM is not recalling the vehicle for this defect. We have been unknowingly driving around breathing in black mold. As someone who is immunocompromised with an autoimmune disease, this is especially troubling to discover. My autoimmune disease was sucessfully managed with medication since 2017, however, shortly after leasing the vehicle in March I began to experience flare ups. I have been unable to determine why, but this discovery makes me believe it was due to the mold in the vehicle. From discussing with my doctor, mold exposure is a potential trigger of my condition.

Returning home on I-40 on Sunday, the engine just quit working. Fortunately it WAS Sunday and the traffic was light. Had there been more traffic, someone probably would have hit me from the rear. We managed to get it almost all of the way off the road before it stopped. According to the dealership that worked on it, it was the fuel supply service module, $46.09 part. The service technician said they had been having a lot of problems like this and knew what to do. All of the code were lost because to tow truck driving had to take the leads off of the battery. That was the only way he could get the car out of park in order to tow the vehicle.

This car is equipped with a telematics module that feeds information to navigation system, Blue Cruise hands-off driving, and provides speed limit information in a heads-up display based on map data. The same module also controls connectivity to On-Star, a safety monitoring service. There appears to be a bug in the software whereby the module doesn't appropriately initialized properly. This has several effects. The OnStar system ceases to function (and the attendant feature of calling emergency services in a collision). The bug also causes false GPS coordinate data to be fed to the car; since the reporting of the speed limit and other alerts are based on this data, along with the Blue Cruise hands-off driving, the driver is presented with false information about the speed limit on the current road (instead using data about the road at the false GPS coordinates). If using guidance, the guidance presents the driver with false and confusing directions (which change frequently as the system believes the driver is in a different place). This bug has happened about 6 times in the past 6 months. There's no mechanism to reset the unit other than disconnecting the battery or fuse. The attached file shows a typical event. The guidance clearly shows the car in the middle of the Charles River in Boston, and the navigation system is instructing the driver to get on Memorial Drive. The HUD (not shown) indicates that the current speed limit is 20 MPH. This picture was taken while on Interstate 93 in Medford MA (speed limit 65 MPH).

When using the factory-installed wireless charging pad, my phone becomes extremely hot within minutes of charging. The heat builds quickly, to the point that the phone must be removed immediately to prevent potential damages or safety risks. This has happened consistently, and I have not removed the phone case because I should not have to- the charging pad is designed and advertised to work safely under normal use conditions, which includes phones in standard protective cases. Regardless, the level of heat generated is excessive and concerning. This issue raises serious safety and design concerns, including the potential for battery damage, device malfunction, or even fire risk.

Telematics module failure. Causes GPS to provide erroneous navigation prior to complete failure. Started as 1/2 mile, then grew to over 30 mile deviation from actual location. The module also takes out several safety and monitoring systems monitored by OnStar. All in-car communications are lost, which means driver has to revert to using a cell phone directly for basic functions proved through infotainment system.

2025 Chevy Equinox - beginning of July, i got back to my car at the airport and it would not turn on. nothing happened and i had to call onstar with my cell phone. a tow truck was sent and my 2025 Equinox (which i bought end of Oct 2024) with only 8000 miles, was towed to Chevy dealership. the next day the dealership said it was a faulty battery and they replaced it. i went to pick up my car and then a couple weeks later i tried to autostart my car and it did not respond. I called Onstar from my phone to talk with them and then they asked me to go to my car and push the button. it was green however it was not responding. i was told to take it into the dealership and tell them i am having an onstar issue and it wasn't responding. I took my car 3 weeks ago (Aug 11th) sat for 4 hours waiting on my car only to be told that they were not able to fix it. that my entire onstar system needs to be replaced. they said they ordered it but that it was back ordered and do not know when it will be in. and to call in 2 weeks to see if there were any changes. i called 3 weeks later and still they had nothing new to tell me except that they don't know anything. from reading online i see that this onstar module issue had contributed to other issues with the car. i knew that there was an issue that triggered the battery to completely die. and with all the other people that have said they have had issues , it is very apparent that this caused my battery to die. Now i am still paying for onstar but not able to use it. i am obviously paying my payment on my car without being able to use all functions of the car. I am at a total loss on what to do next.

they have the gear shift stick near the wheel like older models. you have to brake to move the gear shift and push a button in on the gear shift to park. However, when driving you can move the gear shift, which I have done accidentally. The gear shift does not lock while driving. Twice the gear switched to L2, which I do not know what that is but it causes my engine to over work. This is dangerous especially trying to switch the gear back to D when at a speed of over 50mph.

I leased this vehicle brand new. At around 500 miles, the vehicle had occasionally a humming noice, at 1900 miles the humming noice is loud with vibration. My suspicion is a structural defect, my fear is to end up with half a vehicle on one lane, the other half in the other lane at the expressway. I have recorded several of the occurrences, provided a GM dealership with the recordings, contacted GM Executive offices, and have not been able to resolve or advance, meanwhile my household is without a vehicle. Neither GM nor the dealership is willing to provide a courtesy vehicle. The dealership was unable to duplicate my complaint, GM executive office agent recommended me to take the vehicle to a different dealership for a "second opinion". This is depriving me of work, transportation and giving me additional work.

Backup camera not working and the display on dash shows triangle and a camera crossed out. Dealer has been advised 1 month ago. The Camera is supposed to be on backorder.

Windshield has cracked on 12/18/24. Chevrolet and General Motors have provided no update on windshield availability which is now a safety concern as the crack continues to spread

There are 2 big and long distortions in the windshield that effect the view. Viewing out of the windshield is hindered by causing objects to look distorted and different than reality. There is one on the right and left side of the windshield effecting the view of both sides.
