CHEVROLET Complaints

Under 13k miles the tire developed a bubble on the sidewall. The week is 3824 which is just two weeks prior to the 4024 tire run that was recalled.

Shifter assembly- Shift to Park. The 2018 Chevrolet Traverse repeatedly shows a shift to park message when the vehicle is already in park, this causes the vehicle to not turn off. I have already had this issue fixed by a dealership previously and the issue has come back yet again.

While slowing to a stop, the vehicle suddenly experienced multiple (3–4) violent jerks. The vehicle fought against my firm brake pedal application, overpowered the brakes, and accelerated uncontrollably, resulting in a crash. During the impact: • The driver frontal airbag and pretensioners deployed. • The driver seatbelt unlatched mid-impact and then locked/retracted in a way that prevented it from latching again, even while I was sitting in the driver’s seat post-crash. I have only been provided with the limited Airbag Control Module (SDM) data, which shows the brake switch as “Off” and low accelerator pedal readings. This data does not match the events I experienced. I have formally requested full downloads from all other modules (Powertrain/PCM, ABS/EBCM, BCM, etc.) from both the insurance company (ESIS) and GM, but they have only provided the single SDM report. This appears to be a sudden unintended acceleration event combined with a brake override failure and seatbelt restraint system malfunction.

My vehicle would not shift into reverse. Took it into the Chevrolet service and they said the Valve body needs replaced. There are known issues with the Valve body in 2021 Tahoe but they said it is not covered under any of the GM extended warranties. It should be covered under Special Coverage N242454441 or N242454440, but they said no coverage. The vehicle only has 46,200 miles on it

started with a broken key, the security system passlock lll+ left me stranded in winter. I got it working temporarily after finding the other part of the key. put it in ignition and then the other half to get it started but didn't always start. apparently this is common on Chevy vehicles.

The vehicle was taken to College Chevrolet for body work. . When the vehicle was at the body shop, the shop informed me that a turbo light was on but I am unsure when it appeared because it wasn't on when I took it to the dealer. The brake assist light was on; I noticed this about May 20, 2026. I parked the vehicle. The vehicle was driven to the body shop on June 1. The body work was completed on June 9 and the vehicle was at my residence. My Ex-husband and son were coming to pick me up at the car rental. The car caught on fire. My son & Ex-husband could have died in that car. The vehicle is available for inspection. The vehicle hasn't been examined by anyone at this time. An insurance claim in in process.

LandGolden LG17 185/55R15 82V All Season Radial Tires purchased from Amazon (seller: Priority Tire) and professionally installed. Tires have been balanced and rotated approximately every 5000 miles. Less than 30,000 miles and tires are already at 3/32" tread due to manufacturing defect, per multiple tire stores. Older tires on same car (different brand tires) have worn down significantly less than these LandGolden tires. The advertised tread life for these tires are 65,000 miles.

Issue 1: Cooling Fan Remained On After Engine Shutdown Component or system involved: Engine cooling system and fan control system, including the radiator cooling fan, fan relay, coolant temperature sensor, wiring, or engine control module (ECM). The vehicle is available for inspection upon request. What happened: After turning off the engine, the radiator cooling fan remained running continuously for approximately five minutes and would not shut off as expected. No warning light, message, or other dashboard indication appeared before or during the event. This was unusual behavior compared with normal operation. Safety risk: The unexpected fan operation created concern that the cooling system was malfunctioning and that the vehicle could overheat, experience an electrical problem, or become unreliable while driving. A cooling system or electrical failure while in traffic could put me and other drivers at risk. Reproduction or confirmation: The issue occurred several time and was confirmed by a Chevrolet dealer, and was told that my warranty did not cover the issue. I took it to outside mechanic to fix the issue as Chevrolet wanted to charge over $1500 for the issue. No warning lamps, messages, overheating indicators, or other symptoms appeared before the fan remained on. The problem occurred suddenly back in 2025. Issue 2: Ignition Key Gets Stuck and Cannot Be Removed Ignition lock cylinder, ignition switch, transmission shift-interlock system, park-position switch, or steering column lock mechanism. The vehicle is available for inspection upon request. The ignition key intermittently becomes stuck and cannot be removed from the ignition. The problem occurs after parking and turning the vehicle off, and I sometimes need to move the shifter or steering wheel repeatedly before the key can be removed. A stuck ignition key can prevent me from properly shutting down and securing the vehicle. It may also indicate a failure in the ignition or shift-interlock system.

I am submitting this complaint regarding my 2020 Chevrolet Blazer and what appears to be a widespread cooling system defect. My vehicle has developed a coolant smell outside the vehicle, which raises concerns about a coolant leak from the radiator. After researching the issue, I discovered that numerous Chevrolet Blazer owners have reported similar coolant-related problems, including radiator failures, coolant leaks, and persistent coolant odors. These complaints are widely discussed across online forums, social media, and owner groups. General Motors appears to be aware of this recurring issue, yet many owners continue to experience failures within and outside of warranty coverage. The coolant smell is concerning because it may indicate a leak within the cooling system, which could lead to overheating, engine damage, loss of vehicle reliability, and potential safety risks while driving. Owners should not be experiencing major cooling system failures on relatively modern vehicles. I request that NHTSA investigate the cooling system and radiator issues affecting the 2020 Chevrolet Blazer and determine whether a defect exists that warrants a recall or other corrective action. The number of similar complaints suggests this may be a systemic issue rather than isolated incidents. General Motors should be held accountable for addressing this widespread problem and providing a permanent repair solution for affected owners. Thank you for your attention to this matter.
