CHEVROLET Complaints

September 2025, January 2026 and March 2026 on the freeway heading into the caldecut tunnel and the car jerked check engine light came on and the engine went into reduced engine power. All three times the car had to be towed into the dealership, all three times the fuel pump has been replaced. This is a 2024 Equinox. Anyone living in the bay area knows what the traffic is like, my son could have been killed any of these times due to faulty parts being replaced into a new vehicle. Contacted GM and they refuse to buy it back. I see there is a class action suit for faulty fuel pumps but they seem to keep replacing the same faulty parts.

Automatic emergency breaking engaged while driving through an intersection when there was no danger or incoming car or need for it. If the car behind us was not paying attention they could have rear ended us.

2021 Silverado tailgates often stop working due to a faulty, corroded electronic switch caused by water intrusion. A major 2020-2024 GM recall exists for this, which can cause unexpected opening. Check for corrosion in the tailgate switch/connector, a pinched wiring harness, or check for a blown fuse. This is the 2nd time my truck is at ganley Chevy in Cleveland Ohio. They already fixed 1 rotted wire due to corrosion. And now having same issue again that tailgate won’t open. They told me approximately 1000.00 to find and MAYBE fix the problem. This truck should be included in the recall as to it falls under the year of the issues and that it’s the same EXACT ISSUES AS LISTED Again they have my truck in shop and I feel my truck falls under the recall proximity of said items.

The upper radiator hose on some huge percentage of these trucks fail (mine has failed at just over 20K miles). You can check the Colorado Chevy forum, youtube, etc., et al, and find plenty of instances where this has failed. As this is the cooling system, it can cause the engine to overheat and potentially ruin the engine. The flaw seems to be an engineering issue with the rubber seal they use (instead of a high quality o-ring) to seal the upper hose to the radiator. Additionally, since this can cause engine failure it should be addressed immediately. Instead, my local Chevy dealer, since its not a recall item, said they could schedule a time next week for me to LEAVE the truck and then they would get to it in 7-10 days. This is extremely unfair to the consumer who depends on these vehicles. This should absolutely be a recall item. You can find 1000's of examples online and if you can pull GM repair data, I'm sure you'll find 1000's more.

This has happened three times with the 2019 Chevrolet Silverado 2500HD LTZ truck. Each time, the failure was following a remote start in my driveway. It has occurred at the approximately 40K, 80K, and now at 128K mile mark. First two repairs were covered under the warranty and extended warranty, with the third time there was no warranty and the cost for repair was ~$2800. Each time, the vehicle was remote started in the January timeframe with cold (0 to 30°F) temperatures to allow the vehicle warm up prior to driving. I know two of those events occurred when we had a more significant temperature drop as there was snow on the ground. Upon getting into the driver seat and putting into Reverse to back out of the driveway, I discovered the brakes and power steering had failed. The dealer on this third time indicated a check valve somewhere was "sticky" resulting in the failure of a hose with a booster tied to either the brakes or power steering (not sure which) failing taking the other part out. In this third case, either power steering or brake fluid vapors had been sucked back into the heater as things had sprayed around the engine compartment. The cab of the vehicle presenting a haze/fog in the vehicle causing me to realize there was something wrong upon opening the truck door. All three times, the vehicle was towed to the dealer for service repair. I do not know if this could have presented a fire hazard or had I been driving down the highway or interstate how fast I would have lost braking or steering ability.

Turned on vehicle on 3/2/2026 and received a message stating "Anti-lock break system failure. Drive slow and stop cautiously." I test drove my vehicle in my local neighborhood and discovered that my brakes were only functioning at about 20% and would only respond if the brake petal was pressed all the way down. My car was towed to the local dealership to be assessed and was determined to need Reservoir 4.651, Cylinder 4.650, and Fluid 8.800 when it was picked up on 3/6/2026. Under further review of this report I came to discover a class action lawsuit for this vehicle make and model relating to cylinder part #85762161. I am unsure if my original part was that part number, but my experience closely mirrors other's that have been reported for the same issue and part repair. The part that was also replaced in my vehicle after the repair was part #85762161. Some individuals in this lawsuit have reported 100% brake failure. I am fearful to continue driving the vehicle knowing that there could still be ongoing issues with the part that directly relates to the brakes.

The contact owns a 2021 Chevrolet Tahoe. The contact stated that while driving at various speeds, the Forward Collision Avoidance message was intermittently displayed. The vehicle was taken to a dealer, where a computer module was replaced. While driving at various speeds, there was an intermittent knocking sound coming from the engine, with the check engine warning light illuminated. While driving at an undisclosed speed, the knocking sound became constant. The vehicle was driven to the dealer, and upon inspection, the mechanic discovered a bent engine rod inside the engine. The vehicle was diagnosed with engine failure, and the contact was provided an estimate for the repair. Upon investigation, the contact discovered the failure was associated with NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling). The manufacturer was initially notified of the failure through the dealer, and the contact was later informed that the manufacturer agreed to cover half the cost of an engine replacement. Upon calling the manufacturer directly, the contact was referred to the NHTSA Hotline to report the failure. The vehicle was not repaired and remained with the dealer. The failure mileage was approximately 72,000.

I was driving down the road at approximately 55 mph when all of a sudden, my truck decelerated and a warning signal displayed on my dash indicating my speed was being forcibly reduced to approximately 30 mph. Fortunately, I was on a rural road versus the interstate. I pulled over and had an OBD2 reader. The reader indicated I had a P-2138 error code from a "voltage correlation error between the two Accelerator Pedal Position (APP) sensors". I was able to limp along with emergency flashers to return home. After driving approximately 10 miles, the "issue" resolved itself. I have since replaced the gas petal assembly after learning this is a common failure on many years of the Chevy Silverado series.

The contact owns a 2015 Chevrolet Silverado 1500. The contact stated that while making a turn to the left or the right at slower speeds, the vehicle stalled and lost automotive power. No warning light was illuminated. The contact stated that the vehicle was restarted as a temporary fix. The vehicle was taken to a local dealer, where a ground cable replacement was performed. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken back to the same local dealer; however, it was unknown if the vehicle was diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 65,000.

The engine oil cooler failed causing engine oil to leak into the coolant system on my 2024 Chevy Silverado 3500HD. This requires a full replacement of the coolant system. In addition, excessive sludge buildup inside the motor is caused. This is a known issue with GM for 2024 Diesel vehicles. GM has released a service bulletin but is fighting my local dealership on the required repairs.
