CHEVROLET Complaints

I took my truck in for the recall on the L87 6.2 engine PCOED test and they said it passed. They changed to the 0-40 oil. I noticed a significant fuel mileage drop from mid 20 to low 14 on long highway drives. I had an oil change done and drove 500 miles the next day and there was just a trace of oil on the dipstick. I called my chevy dealership and they said that is normal for oil consumption. I topped off the oil before heading back home and used 3/4 of a quart. I am watching my oil consumption and looking to do an oil consumption test done by the dealership. They did not recommend this test I researched it. I am concerned my engine will blow up.

An electrical component related to the vehicle's rear sliding glass window and rear defroster malfunctioned and overheated, causing smoke to fill the cabin of the truck as it was being driven down a busy highway. Immediately following the smoke, the rear window violently shattered due to overheating from the malfunction. This dangerous defect was known to exist in our model and year of truck, as documented in Customer Satisfaction Program N192265660. This bulletin shows that GM knew about this exact issue, yet allowed the vehicle to be sold and driven. This incident was incredibly dangerous and easily could have caused my wife (who was driving) to crash the vehicle due to limited sight and distraction. My wife called me following this incident and was terrified and confused. There were no warnings, signs, or symptoms suggesting an issue with the electrical component until the incident occurred. We immediately contacted GM, who advised we were not permitted to get the vehicle fixed until they completed their inspection; however, it has been nearly a week and no inspection has occurred at this time.

Intermittent loss of power steering while driving and at start up. Warning indicators flash "Service Power Steering Drive With Care" and "Service Stabilitrak." Most of the time, when you turn off the truck and turn it back on again, the message will clear and all will be fine again. However, a week or two will go by and it happens again. The last time it happened, it would not clear right away. Finally, it did the next day. GM says there was a recall on my truck that was repaired for this problem but I'm seeing a lot of people online still having problems. This is very dangerous because I cannot physically steer the truck when the power steering goes out. I'm very concerned that me or my teenage son who drives it is going to get in a serious accident.

I was leaving my farm property after loading my truck and tailgate and drove home 20 miles. At some point in the drive my tailgate dropped and fell onto the trailer tongue. This caused damage to my tailgate. I have called the dealer and they informed me there was a recall on the tailgate latch but they completed the work on the recall defect. I am questioning this and want to understand what to do now. I don't trust the tailgate and the truck has no warning system for when the tailgate drops like a door open signal.

Generator Control Module, I seen there was recalls on 2013 Chevy Malibu Eco equipped with eAssist. That is what my car is and the GCM is out of it.

Sudden power loss on highway. Engine would not respond. We were fortunate to have been able to pull over to the side of the road but in an unsafe merging area. Vehicle restarted after multiple attempts, but engine would not exceed 3000 rpm causing unsafe speed on highway. Engine died again causing total power loss. I was able to coast down the hill to safely park out of the way of traffic. Tow truck was needed. Vehicle was towed to dealer where it was purchased. After inspection, the engine was confirmed to have failed. The dealer advised for engine replacement as part of the L87 recall. This engine was previously inspected less than 10,000 miles prior as part of the same recall, and the higher-weight oil had been used since per the manufacturer's recommendation. However the inspected engine appears to have failed regardless. This sudden loss of power happened about two weeks prior, with the driver able to pull to safety and restart. It was dismissed as a fluke since it did not occur for the next two weeks.

Was driving on highway and engine started to make a noise, performance and power were impacted, the engine service light appeared. Exited highway on near offramp, when on offramp vehicle engine stopped working. Vehicle is a 2025 Chevrolet Suburban with 6.2L engine. Dealer has stated engine is seized. Seems exactly like the current 6.2L engine recall for 2021-2024 model years that results in engine failure. Vehicle is 7-8 months old, and only has roughly 12,000 miles.

On April 29, 2025 we took our truck in for these 3 recalls Serial Data Gateway Module • N242435631 -Fuel Injector Flow Rate• N242450630 - Park Assist Retrofit - Exp 05/31/27• N222375790. We picked the truck up and had no issues. Then on November 28, 2025 our fuel injector 2 went out. According to articles we have found the recall for the fuel injector flow rate specifically addresses the ECM not controlling fuel injector flow rates and because it was not doing this correctly it put added stress on the fuel injector #2. We took the vehicle to Ken Garf Chevrolet American Fork Utah and they diagnosed the issue as the fuel injector 2 being bad. They quoted us with parts 2000 dollars to fix it. After researching this recall information we took the vehicle to Sky Chevrolet in Provo Utah where we got the vehicle and where it was serviced in April and asked them to look into the fix. They are telling us that they cannot find any correlation between the fuel injector flow rate and the fuel injector 2 going out so they are wanting $600 dollars to fix the fuel injector flow rate. The next thing since the N242435631 update was performed, the automated clock on longer syncs. This is a known side effect of the gateway module update. We were again told that they could find no correlation between the clock and the recall. When doing research we found that that the 2 are very much connected. I would also like to complain about Ken Garf and how they "diagnosed" an issue we told them was already there. I would like to refunded the 200 dollars for the diagnostic fee.

While driving home from work the truck displayed numerous trouble codes including ebc failure, braking failure, traction control failure and trailer brake failure as well as vehicle governed to 42 mph. I took it to the dealership and they checked all of the braking system and could not find any issues. They reset the codes, and changed all 4 pads and rotors as all 4 wheels were 1/32 out of true as a precaution. I drove it home about 5 miles with no issues. The next morning I was on my way to work and the codes reappeared with me being governed to 62 mph. At the stop sign I had no braking at all. Pumping the brakes resulted in no braking or pressure in the pedal. Luckily there was no traffic and I was able to use a hill to stop. I turned around and went the mile back to my house and was unable to stop again ending up with the front end in my neighbors yard. I had the vehicle towed back to the dealership where they still have not found a cause or a solution to the issue

The contact owns a 2021 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, the vehicle jerked unexpectedly. The check engine warning light was illuminated. The vehicle was taken to a local dealer, where it was diagnosed, and determined that the valve body needed to be replaced. The vehicle was not repaired due to parts not being available and the VIN not being included in a recall. In addition, the part was ordered at the owner's expense. The manufacturer was made aware of the failure. The failure mileage was approximately 145,565.
