2023 Chevrolet Silverado 1500 Other Problems

Your DEF (diesel exhaust fluid) gauge isn't working correctly. After filling the DEF tank, the gauge won't show it's full, and it sometimes reads over half full but then suddenly shows empty within minutes, triggering a limp mode warning even though DEF is actually present. Your truck has also gone into limp mode while the DEF tank was actually full. The fix likely involves diagnosing the DEF level sensor, which may need cleaning, recalibration, or replacement.

I am sending this email to report that my 2023 Chevrolet Silverado had its rear brakes lock up momentarily on consecutive days (1/13/26 & 1/14/26) driving 70-72 mph.  Each occurrence came on without warning and only lasted a brief moment, but locked up hard enough for my rear wheels to screech and slam me forward in the truck, thankfully there were no other vehicles near me. I took the truck to the dealership first thing in the morning on 1/15/26 to be informed later that day that the truck didn't show any codes.  The service department at my dealership contacted the TAC Dept. at GM and they determined that the problem was caused by the brake light wiring from my truck topper (that was after they asked if the customer had added any accessories to the truck).  I have had the topper for 3 years without any issues.  I reached out to the company that installed the topper and the owner said that GM is giving me the run around and trying to point the blame elsewhere. He himself has installed 100's of toppers and they follow the wiring instructions from Leer Toppers. He did a 30 second Google search and said [XXX] , the problem you have experienced is well documented online, GM knows what the problem is with your truck". My truck was at the dealership for 5 days before they released it to me, even after I told them that there are known and documented cases of their trucks experiencing momentary rear wheel lockups. I have called GM Customer Service twice and left messages regarding my truck and TAC # and haven't received a return call. I am fearful that when this happens again and if it does so in the wrong place at the wrong time the end of this story may be tragic.   If I was pulling a trailer, driving on ice or in rush hour traffic I can't imagine the outcome. GM knows they have a serious problem and they is comfortable in releasing a dangerous truck back onto the roads.

On 1/24/26 I used the remote starter to warm up the truck and it started but within 3 minutes it shut off. The temperature was in the single digits. So I tried the remote again and it wouldn’t start. And the remote start hasn’t worked since and the check engine light is on. Two years ago when the brake module failed right before that recall the temperature was very cold that day too. Just two months ago the check engine light came on and that time the dealership said the battery failed . It also printed out a whole page of errors , at the dealership.

The vehicle 'turned off' while in motion at around 35-40 mph on a busy 5-lane major arterial road in the city on 12/21/2025 at around 0630-0700 hours. Driver (author of this report) was able to turn into a side road and stop. Message "Press start button" displayed on dash panel. Complying with this action led to a coughing start but vehicle could not be put into drive mode because a second message appeared saying "Conditions not safe for transfer". Eventually over next minute or two vehicle coughed up to a start again and was able to put into drive mode and drive to parking garage to safety. Driver was able to drive back about 3 hours later with no recurrence or new malfunction. No warning lights throughout the episode. My Chevrolet mobile app also did not display error messages. Vehicle was driven (without incident) and delivered to a Chevrolet dealer on 12/24/2025 for diagnostics and workup and is currently situated there.

Yesterday I was driving and the pickup truck put itself into neutral and died in the middle of the road and almost got rear ended with my kids in the car. The car would not start again and no codes were given.

I was driving my vehicle when the check engine light came on and a message then came across the screen and stated the truck would no longer shift if I didn’t stop driving it. I took It immediately to Autonation Chevrolet Service on Nov 9. I received it back on 11/26 my service advisor said it passed inspection that no work was completed I needed to use high synthetic oil and filters for my truck to keep it going. This doesn’t sound correct when I’ve owned several Chevy/GMC trucks. I only have 33k miles on my truck and want the recall fixed. Please help me get this taken care of.

GPS system behaves erratically. (Position jumps around). Phone gps very stable. While using navigation in the truck the jumping position causes the map to jump and swing also it lags behind missing turns etc. This is proving to more of a distraction making me look at the map longer. I tried dealership and they said it works while I have video evidence of its behavior. I will try another dealership but maybe thousands of others are having same issue and this help to force a fix.

OnStar Module needs to be replaced and of course the module died right after the warranty went out. After research come to find out this is an issue with all GMC and Chevy vehicles

It burns a significant amount of oil. I had an oil consumption test completed with a GM dealership, they state it is in their guidelines of standard. It burns around 2 quarts of oil within 5000 miles, so between oil changes. The add oil alert popped up while I was driving down the highway. My truck has 33500 miles on it, it should not be normal for a new truck to burn that much oil. They will not check my engine to identify the cause because they state it is within their standards.

I was traveling when on my dash came up "software update available" so I looked at how to and said truck will need to be off for 15 minutes during software installation so I decided to wait until I got home from trip. So on the moring of October 2, 2025 did the software update in my driveway. Then in the afternoon needed to go somewhere and I saw the service engine warning symbol on dash. Went to where I needed to go, 4 miles from home. Then when I was finished headed home and on way home warning on dash came up, "Service Transmission Now Unable to Shift Soon". So I got home and made some phone calls and ended up taking truck into Polar Chevrolet, White Bear Lake, MN. Thursday before they closed. Friday October 3 got a call from Polar Chev and issue is "Gearshit control module", part number 86515985. But was told part was out of stock and could take 1 week or even upto 1 month for them to get part. Looking on internet did see that this warning has come on from other people right after they did the software update. Needless to say my estimate for repair is going to be somewhere form $900 - $1000. So now have to wait and see when they get part and if it is actually issue.

My onstar module stopped working on my 23 chevy silverado. I am planning a vacation and with out onstar I risk being stranded without this service. My WiFi does not work I can not see the speed limit I am unable to contact onstar for help if needed whether that be for directions, or help if I have and emergency. I can not use the handsfree google assistant I took it to my dealer and when I took it I was 400 miles past the warranty. I was not aware of the issue until I tried the handsfree google assistant and if did not work.

Water Found in Rear Interior of Cab, Water Leak at Rear Sliding Window. I noticed water spots on the left and right sides of the headliner. I took it to a dealer (Malloy Chevy winchester Va), and the said it was a TSB put out on this problem and they would file a claim. The truck has 48000 miles and the bumper to bumper company denied the claim. Have the TSB didn't matter to them. Can you assist in any way with this?

Unknown…Randomly started on fire after driving. Police report was filed under 25-000653/Altoona Police (I don’t have a copy)

The tail gate on my 2023 Silverado has started to open on its own both while driving and while stopped as well as attempting to open every 3-5 minutes while the vehicle is off. I contacted Chevrolet after I saw there was open recalls for this exact issue to see if my truck was covered with this recall and to my chagrin it is not. But from what I read, this is the exact issue that other drivers of Silverados between the years of 2020-2024 have been experiencing.

I have a 2023 Chevrolet Silverado 1500 and the OnStar is completely out the dealership say they have no idea when a module will be ready. I have talked to and seen several forums on this. Everyone states it’s a huge problem and now they want to charge up to $1000 to replace the module it is not covered by warranty. I cannot even use my navigation my security all the things that OnStar provides due to this module problem they have it seems to be getting bigger and more widespread. We should not have to pay for something that has nothing to do with the warranty of the truck. It is a malfunction with OnStar and Chevrolet

Moter blew with 19,000 miles on a leased vehicle. Blew a rod out of the block and there was no warning light or notice at all. Almost got rear-ended. Took 3 months to replace moter. New motor knocks and ticks...... I also told them the 10 speed transmission slips between seventh and eighth gear they said there's nothing wrong truck still slips between seventh and eighth gear to this day.

The sound on the Infotainment system, which controls the radio, apple car play and phone calls cuts out randomly and will not turn back on until the truck is turned off for 10 minutes or you pull over and park and do a reset in safe mode. This is a hazard as you can not make emergency call while driving or if you are on an emergency call while driving you are forced to go from hands free to holding your cell phone while driving. I reach out to Chevrolet several and brought the truck to 2 different dealerships and it is still not fixed.

randomly several times a day the google assistant comes on unexpectedly and starts to talk, via the infotainment system. She says "I cannot do that but in the meantime you can......"

After repeated software upgrades, the infotainment system continues to drop bluetooth calls causing the driver to pick up the phone manually. System will drop the connection several times during a 5 min call. This causes the driver to get distracted. Radio system has been updated twice under warranty. Problem is still not resolved.

The way the hood on my truck was designed should be modified. If the sun hits my hood it about blinds me, the glare is very bright. One time I couldn't see the road for a minute or two. The sun visor does not help or solve the problem

Forward collision system will light up and state it is not functioning. Will reset once truck is turned off for a bit. Stereo audio will intermittently cut out and stereo needs to be reset to hear audio again. Apple CarPlay will intermittently not connect

No idea where the problem lies due to inconsistent trouble codes, the truck will randomly start jerking and sometimes kill itself after throttle won’t respond no matter the speed. Every time I’ve had somebody drive it, it does not act up for them. I’ve had several parts replaced with the same problem coming back 50+ miles later. When it gets ready to shut down it throws the check engine light, service esc, collision light, and traction light, then says speed reduced or speed will be reduced in 175 miles. I have video evidence of all of this.

Vehicle caught fire and burned up while idling at my babysitters

The audio from the stereo will cut out for all services, FM, Sirius XM, Apple CarPlay , phone. It’s happened twice within two weeks. Once I reset the stereo in safe mode., it works again.

We purchased a 2023 Chevrolet Silverado High County on Thursday, August 10, 2023, at Reed Chevrolet in St. Joseph, MO. On August 19, 2023, the infotainment system failed on the vehicle. It was returned to the dealership for repair. In coordination with General Motors, the dealership could not fix the issue. They said a new infotainment system was required, but they did not have a strategy or solution to our problem. They indicated this was a supply issue, and they could not get an infotainment system as it was back-ordered. On September 11, 2023, the dealership had to trade us vehicles as they could not provide a time frame for repair. We had to give up the 3.0 straight 6 Duramax diesel we wanted and go with a gasoline version. In communication with GM, they were aware of this problem, based on the careful wording of their responses and the 2021-2023 model year Silverado pickups. I researched these model ears and found this was a common problem among many Silverado owners. GM is also well-known for this issue infotainment issue and has settled a previous class action lawsuit for different model years. GM needs to be held accountable for this issue. I look forward to your response. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle experiences unexpected sudden acceleration, usually at low speeds. Engaging the brake will stop it.

The backup camera intermittently turns off in low light, thus rendering it ineffective at night. It's been identified with NHTSA ID Number: 10234211. However, there is no fix. I feel this is a safety issue as the camera does not work correctly in low light. It has been this way for approximately 6 months, since I purchased the vehicle.
