CHEVROLET Complaints

The back window shattered in my driveway after Getting in car to go to work. Happened when shut the door.

On Saturday, April 18, 2026, I was driving home from a neurology appointment with my two daughters, including my child with special needs. I intentionally chose not to take the expressway and instead drove a lower-speed route home for safety reasons. While traveling approximately 35 mph, the vehicle suddenly displayed an “Engine Power is Reduced” warning. As I attempted to safely maneuver through traffic and pull over, the brake pedal became extremely stiff and difficult to depress, requiring significant physical force to slow and stop the vehicle. The sudden reduction in braking assist created a serious safety hazard for my family. Had this occurred at highway speeds on the expressway, the outcome could have been catastrophic. A post-incident inspection identified failure of the vacuum pump drive assembly and related timing/variable valve timing (VVT) components. Photographs taken during disassembly document the condition of the timing chain, camshaft, VVT actuator/phaser, vacuum pump assembly, and associated components at the time of repair. Diagnostic records also documented DTC Code P1101 following the incident. The vehicle is currently undergoing further inspection and diagnostic evaluation at a certified Chevrolet dealership to validate CPO warranty coverage and determine the full extent and cause of the failure. Based on the sudden loss of engine performance and reduction in brake assist, I believe this condition represents a significant safety risk to vehicle occupants and the public.

While driving the steering wheel will intermittently lock up or make it where you cannot turn the steering wheel at all. The collision sensors will go off and cause vehicle to lock the brakes up when you’re not even close to anything. Also, random messages will appear in dash as shift to neutral while driving ect. See pictures.

Two years in a row my car leaked a significant amount of water through every light button any hole in the ceiling. It also leaked all over the center counsel while driving and came through the foot pedals all over my feet and the entire floor of the vehicle while driving. The value of my car has been destroyed and Chevrolet is not taking this seriously. They have told me they will only replace the roof liner and half the carpet. They are not acknowledging the potential damage done to the electrical system and the overall value of the car from bad smells that have been caused by dirty water soaking the entire interior. My car is ruined and it should be replaced.

Engine failed on 5/8/26 with 1794 miles. Sounds like possible main bearing failure, engine had 18psi oil pressure. Signs were, knocking, banging, screeching/squealing internally from engine. No codes or check engine lights appeared. Was driving approximately 35-40 MPH on mountainous paved road. Managed to limp truck to safe pull off area and turned off engine. Had truck towed to dealership. If truck would have died on road I was driving on, it could have been bad. Road is very narrow with numerous blind spots.

The vacuum break booster went out. My check engine light came on and it said power reduced I’m not sure exactly. Because my power didn’t reduce but my car seems to be misfiring. Luckily I was going to be turning at a light and there was a few cars in front of me so I wasn’t going fast. As I got closer to the car in front of me I applied my breaks. They would not move and were hard and I gave it all I had to try to get my car to stop and thank god it did. Then my car stalled. I tried to start it and it just kept cranking but wouldn’t turn over, it also would not turn off till about the 3 times I push then button it finally turned off. Yes my safety and others would surely been at risk I wouldn’t have been able to stop in time if someone pulled in front of me or stopped suddenly I would not have been able to stop. If a child ran into the street I inn o way could’ve stopped! My step dad is a mechanic and he also ran a test on the check engine light and it threw 7 codes from this occurring. It didn’t give me no time it was very sudden. Once the engine power reduced appeared on my dash the check engine light came on and my car began misfiring in less then 45 seconds I went to apply the breaks and they were hard and I could barely stop. That was when I was almost about to be at a full stop so I wasn’t going very fast at all and I almost rear ended the person in front of me waiting to turn at the light. Then my car stalled. It all happened within 1 min 30 seconds from the warning my engine power was reduced but my engine power wasn’t not reduced either, and from then my check engine light and it all only took less then 2 minutes to all occur. It was sudden, no warning to think my breaks would not work at all and very quickly it could’ve been so much worse I can’t even imagine. Very alarming and fearful or my life and others from this occurring with no time to react and no idea what happened was going to. I will not buy a Chevy Malibu again and I was going to!

Issue: Total failure of Frontview Camera ADAS sensor, disabling Automatic Emergency Braking (AEB), Front Pedestrian Braking, and Lane Keep Assist. Technical Evidence: GDS2 telemetry confirms a "No Communication" status for the camera hardware. Core safety modules including the Electronic Brake Control (EBCM) and the Inflatable Restraint (Airbag) Sensing Module report active communication failures (DTC U026A/U216A). These safety-critical modules are currently unable to receive the sensor data required for crash avoidance and occupant protection. Forensic Timeline: Vehicle NVRAM reveals a manual "Clear Codes" event occurred at 46,838.3 miles—exactly 0.4 miles after the sale contract was signed. The fault reappeared with a 0 km offset (immediate return) and has been active for 162 ignition cycles, proving the defect existed throughout the dealership's possession. Dealer Response: The selling dealer delivered the vehicle with an unsigned 125-Point Inspection. Despite being presented with GDS2 telemetry proof of the braking and airbag communication blackout, management refused repair, mischaracterizing the disabled emergency braking system as a "luxury feature" and claiming the vehicle is "safe" to drive. Symptoms: "Service Front Camera" warning, intermittent loss of HVAC controls, and gear display (PRNDL) blackout due to systemic serial data bus interference caused by the hardware failure.

The transmission system failed abruptly. I pulled away from a stoplight, had accelerated to 20-25 mph, and then the car came to a sudden stop, as if someone had put on an emergency brake. It continued to act as if the brake was on when I tried to go forward or reverse. I put it into neutral so that I could push it off the road. I realized it would drive slowly in neutral, so I drove it less than a mile back to my workplace. Regarding safety, I nearly got rear-ended when the car stopped suddenly. This endangered me and the other driver. I was headed to the freeway, then would have been crossing a bridge, to get home, so the danger could have been amplified. The dealership's service manager told me that something internally had failed in the transmission. As far as I know they haven't taken it apart to find out what internally failed. They told me that the transmission needed to be replaced. As far as I know, no one has inspected the internal components of the transmission. There were no warning lamps, messages, or symptoms prior to this incident.

Coming to a stop sign or red light the car won’t accelerate or will go in traction control making it difficult to move or not accelerate. Had 2-3 fuel leaks this year also having problems to keep the car going sometimes the max speed it will go is 20-40 miles n won’t go up unless u keep letting it slow down slowly n then accelerating n even after that it won’t make it above 60-70 miles it usually goes with no problem if its down hill since ur not pressing the gas or anything. Turning the air on also makes the car slow down other problems also is the gas running fast could just fill the tank n by the second day it will almost be over. Today the transmission gave up on me now I have no car to move around making it hard for me to go anywhere especially work since that’s how I make my money for living but with no car it’s a big problem.
