CHEVROLET Complaints

Telematics module failure. Causing loss of Onstar, self driving feature, compass, navigation.

The battery energy control module GM Part # 84442220 located inside the HV battery assembly caught fire. The harness that was most affected was the battery cell voltage sense wires. The way the battery voltage sense circuit is manufactured seems dangerous as there is no fusible link between the battery cell and the module. If a short circuit occurs the full current of the cell will be induced on a very thin gauge wire going to the module which will result in a fire.

When taking off it will sometime have hard shifts, shuddering, and acceleration hesitation. While driving, it will do static jolts. Dealer couldn’t pin point problem and advised for a new transmission or we could drive it until it dies. Dealer didn’t recommend to change transmission oil in fear of creating more damage.

I am filing this complaint to report a critical manufacturing safety defect regarding the rear differential in my 2019 Chevrolet Silverado 1500. During a recent dealership inspection at approximately 40,400 miles, an authorized GM service center (Jack Hanania Chevrolet) discovered that the vehicle's rear differential was completely "bone dry" of gear oil . Because there is no history of catastrophic fluid leaks, seal blowouts, or external damage, this strongly indicates that the rear differential was either never filled or improperly filled with lubricant at the factory during vehicle assembly. This issue originally presented as a persistent drivetrain vibration, shudder, and "skipping" sensation starting as early as 12,000 miles . I brought the vehicle to the dealership for this exact vibration at approximately 21,000 miles. The dealership misdiagnosed the issue as "low transmission fluid" (despite the transmission being a sealed system) and failed to inspect the rear differential . The symptoms persisted until the vehicle was immobilized in November 2025, which is when the bone-dry rear differential was finally discovered . A vehicle operating with an empty rear differential poses an extreme and immediate safety hazard. The lack of lubrication causes severe internal heat and friction, inevitably leading to a sudden, catastrophic mechanical seizure of the rear axle . If the rear wheels lock up while driving at highway speeds, it will cause an immediate loss of vehicle control, resulting in a high-speed collision. I urge NHTSA to investigate GM's factory fluid-fill procedures and quality control for 2019 Silverado differentials to prevent a fatal lock-up event for other drivers on the road.

Transmission- lost reverse and some forward gears too. Without any warning signs and no check engine light until hours after. It is going into the dealership on Monday (4/20) and this all happened on (4/17/2024)

Was driving the truck on the highway at 75mph when suddenly the motor revved up in rpm’s and vehicle lost all power. There was no warning lights or any limp mode or anything as such as far as warning. The truck lost all power and could hear metal to metal sounds and turned off the motor. I was able to coast the truck to an off ramp in 70mph traffic. The truck would not turn back on and vehicle was immobile, had to have the vehicle towed by a flatbed to a gm dealer near by. The dealer gave me a loaner pickup and hasn’t looked at my vehicle yet. I bought this pickup less then 3 weeks ago and the L87 recall and oil change had been done prior to me buying it. I was just happy that the truck didnt full shut down at that speed and cause a crash etc. Dealer said motor failure to me and couldn’t confirm a turn around time frame for my truck to get back to me.

The car started locking up my steering wheel. I took it to the mechanic and they ran the codes and said it is the ABS control system module. I called the dealer to get the part and they said it is on back order nationally and it may be months before they can get the part. The 2018 model for Chevrolet traverse has been recalled for this exact thing but my model has not even though this is a known issue. My car is currently not drive able and GM can’t even provide the piece to make it driveable. This is a big issue and I am not receiving any help. If it is on back order it is obvious that it is a big issue nationally yet they have not submitted a recall. The wheel keeps locking up every time I drive it for more than 5 minutes

I was on a road trip and halfway through my check engine light came on and notified me that engine power was reduced while on a 70mph highway. My car the slowed itself down to not exceed 45 then 25mph. I was in a remote area and very far away from a Chevy dealership. I was forced to drive for a long distance to make it to a Chevy dealership that was willing to work with me. Come to find out my fuel pump failed and the car is only 2 years old with only 58,000 miles. This same issue happened a few months ago and I was told by my dealership that it was just update codes required by Chevy that did not update correctly. I’ve had several other issues like this and have been told it’s because the new cars are “basically giant computers”. This car also got a new battery after one year because they stated a faulty or crappy manufacturer battery they put it went bad. My local dealership then tried to charge me for it until I reminded them of my warranty. I take my car for regular oil changes under the 6,000 miles to keep my Warranty Forever. I was terrified driving on highway roads when my car wouldn’t exceed the required speed limit causing other motorists to navigate around me all because I needed to make it to a Chevy dealership willing to work with me.

In August of 2025 I purchased a Chevy MD 5500 from Paul Masse, Inc., in RI. From the time of delivery the truck had a serious shake while operating. Paul Masse, Inc., told me that the tires had flat spots from sitting on the lot prior to purchase. As time went on the dealership placed two new sets of tires on the truck. Neither set fixed the shaking. Paul Masse, Inc., told me that this was how the truck operates and that there was nothing that they could do about it. I continued to contact the dealership for further examination of the vehicle for months with no response. I eventually sent a claim into the RI Dealer Commissioners' office. The commission acknowledged my claim and reached out to Paul Masse, Inc. Paul Masse, Inc., agreed to have their Executive VP, Bob Masse take the vehicle for a ride with me to see what was going on. After driving the truck with Bob Masse, he agreed to bring the truck in for further review. I dropped the truck off a day later, Bob Masse called me after his mechanics looked the vehicle over and told me that they would not be able to fix the truck, but they would offer a buyback if I agreed to take a new truck. I agreed to take the new truck. I had to finance a whole new truck, paying for more insurance, sales and registration taxes. The day I took delivery of the new truck it drove exactly as the old truck drove. In addition to the truck shaking like the old truck, the check engine light was on. I immediately called the Bob Masse, Bob told me to drop the truck off and they would have a look at it. After I dropped the truck off to the dealership, they had it for five days. Bob Masse had called me to say that the check engine light had been repaired, but they were waiting on new tires to come in, as they thought the shaking was once again from "Flat Spots" on the tires. Two days later I was notified from the service department that the truck was ready for pickup. There were no new tires on the truck. Bob Masse said no new tires.

Purchased this car straight out for 4000 from deans car lot in Winchester ky over a week ago. They didn't tell me I had missing fog lights. Keyfob to far was so beat up and bent I could barely get in my car or lock my car not to mention they sent me home in that car with all 4 different brand tires and 4 different sizes. A couple tires are even plugged !! And no wouldn't help me fix any of them. They ignore me. Wasn't no crash. The car lot has been devious and I'm not happy bc that has to do with MY SAFETY. MY LIFE. MY VEHICLE. IM ROYALLY PISSED
