CHEVROLET Complaints

While driving on the highway the car lost complete power. I could not even turn on my hazards. After a few minutes, the car made a sound and the screen turned back and I was able to turn the car back on. But it was extremely dangerous and I could have been hurt of killed. I have read this was an issue with the 2024 Trax but it appears this is an ongoing issue.

While driving at highway speed in my 2020 Chevrolet Silverado 3500 Duramax, the transmission suddenly failed and locked up without warning. This caused an immediate loss of vehicle function and created a dangerous situation while traveling in traffic. I had my two children in the vehicle at the time. I was able to safely maneuver the truck to the shoulder, but the vehicle was no longer operable and required towing. This failure occurred only a few months after a transmission replacement and follows prior transmission repairs, including a valve body replacement performed by a GM dealership. This is a repeat transmission failure and presented a serious safety risk due to the sudden nature of the failure at highway speed.

The CarPlay no longer gives me accurate directions. The directional arrow drifts on the map and sends me everywhere except the direct route. I've tried using both Google and Apple maps to no avail.

I purchased a 2023 Chevy Tahoe in Oct 2025. Since then, I have been trying to figure out how to set up the myChevrolet app. The OnStar button doesn’t work so I called OnStar. After multiple calls, they told me that the account is linked to the previous owner and can’t be transferred because of a faulty telematics communications module. The faulty module is also causing the clock to run slow, which indicates battery drain is beginning. The OnStar module failure poses a huge safety and privacy risk. Safety concerns include battery failure that can cause me to be stranded and the fact that the previous owner has the ability to start my vehicle at any time, even while parked in my garage posing a risk to my family’s health/life with trapped carbon monoxide building up. Privacy concerns include the previous owners ability to track my vehicle, lock and unlock doors, access my contacts, call log, location, and more. This is a significant risk. The dealership should not have sold me a vehicle with a defective module without repairing it and now refuse to fix it. This should have been included in GMs factory recall for 2023 Tahoe TCU’s or a new recall should be issued. Consumers should not bear the burden to fix a widely known safety, health, and privacy risk.

My 2021 Chevrolet Suburban stalled while driving in late September 2025 and had to be towed to a dealership. The vehicle is subject to an active fuel pump power control module safety recall that has been in effect since 2021. The vehicle was brought in specifically for repair of this issue. The work was processed under warranty, and I was charged a deductible. After learning the repair was directly related to an active safety recall, I requested reimbursement of the deductible, as recall repairs should be completed at no cost. That reimbursement request was denied. I have since been informed that the recall repair was never “completed,” and the recall still shows open in the manufacturer’s system. I am now experiencing shuddering and symptoms consistent with a potential stall recurrence. The original stall occurred while I was transporting my children, including special needs children who require regular transportation to school and therapies. The vehicle failure left us stranded at night in an unsafe area. Due to the prior stall, the unresolved recall status, and the recurrence of symptoms, I do not feel the vehicle is safe to operate.

The contact owns a 2024 Chevrolet Silverado EV. The contact stated that while operating the vehicle in sub-zero temperatures, the HVAC unit failed to blow hot air through the vents. During the failur,e the contact was unable to defrost the windows. The vehicle was taken to the local dealer who determined that the heater control module was inoperable and needed to be replaced. The vehicle was not repaired. The contact was informed that the heater control module part was on a national back order and currently not available. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was 13,000.

Vehicle: 2016 Chevrolet Tahoe Mileage at failure: 96,700 miles Component: Powertrain – Transmission While driving on the highway returning home from Columbus, OH, my 2016 Chevrolet Tahoe experienced a sudden transmission failure without any warning. We were traveling in the third lane at approximately 70–74 mph when the vehicle abruptly lost power and rapidly slowed down to approximately 15–25 mph. This occurred in active traffic and created an immediate and severe safety hazard. The sudden loss of speed nearly caused a collision with surrounding vehicles traveling at highway speeds. There were five occupants in the vehicle, including three children. Due to traffic conditions, other drivers were braking, honking, and swerving. I was only able to avoid a crash by immediately maneuvering across lanes to reach the shoulder. The vehicle was disabled and had to be towed. The transmission required full replacement. Total repair cost exceeded $6,000, and the vehicle was out of service for approximately two weeks. I am submitting the repair receipt from the transmission shop with this complaint. After the failure, I learned that sudden transmission failure is a commonly reported issue with Chevrolet vehicles, including the Tahoe. This failure occurred without warning and represents a serious safety defect that put my family and other motorists at risk.

At 46000 miles the motor was replaced because of an internal oil consumption issue after the motor was replaced at 1500 miles the motor locked up while traveling down the road they rebuilt this motor. I went to go pick it up. Drove it 20 miles and oil was blowing out the rear main seal. after this, I sold the truck back to Gwatney Chevrolet and purchased a 2024 model with a 6.2 L I have not had any problems yet.

10L1000 transmission, began having problems with delays and harsh gear engagement. Flare shifting and shuddering. Finally starting having transmission overheating issues while towing. I had to make several unsafe stops with a trailer to wait for the transmission to cool down again before continuing to get it home. Saw trans temps up to 240°F on flat land with 40° outside temps. I could smell the hot transmission fluid inside the truck. When I went to check the fluid level of the transmission, the fluid was full but had a large amount of glitter like metallic flakes. The fluid was very dark brown in color and smelled terribly burnt. The last recall I took in to the dealer for was about the transmissions possibility of failing, locking up, along with the rear wheels at any speed. I have young children that ride in this truck, that in it self was unsettling and unsafe. But then to have issues with absolutely no warning light was concerning. Ive since ordered an aftermarket built transmission to avoid repeating the same issues with a factory GM replacement. My factory warranty had also ended a few months prior to having these problems with it. Leaving me to completely foot the bill for it to be replaced. I had to pull money from my retirement early to cover costs, in fact costing me much more than just the sticker price.

The vehicles oil needs to be checked every day to make sure the levels are not low. The vehicle has no visible oil leaks on the ground or inside, but the oil levels will drop. With that I have to constantly have oil on hand to make sure I refill it or the engine would be dry. It’s becoming a hassle because I have to constantly monitor and make sure that the engine has oil so it doesn’t blow up.
