  In February 2023 we noticed coolant on our garage floor. Car was taken to GM dealership was told radiator seams were leaking. Replaced radiator February 14th 2023 and car had 14,597 miles cost covered by GM warranty. On October 8, 2026 vehicle taken to second GM dealership for driver assist not working be careful. The cooling fan loud when car was turned off. Dealership told us the radiator was again leaking on the seams and will need third radiator (original plus two replacements). The car had 44,328 miles. Cost quoted was $2,125 plus tax and fees. Called GM service line and filed a complaint. They told me car is out of warranty and to ask dealership to give me a payment plan and/or reduce the price. After multiple calls to dealership they said they would give me a 15 percent discount as I am a loyal customer. My wife drives this car and transport two children almost daily. Worried we will lose drive assist when in use possible causing potential issues or accident.

  Torque converters are going out and causing people to need new transmissions. I was told by dealership that evaluated mine this is a known problem! I’ve also encountered others who have same issue with their cars.

  Forward collision avoidance › Warnings · Unknown or other

  My wife and I were just driving and suddenly the motor started stopping installing. We managed to get over toward the curb and shut the motor off and restart it. Then it ran normal. When it did stall out, and we made it to the curb, it shut itself off. That was yesterday then this morning it started to do it a little bit when we left the house.

  Steering assist reduced light came on, fan kept running after shutting off, brought to dealer to see if it was covered under the gm special coverage for thermostat, they say the radiator needs to be replaced for a leak. I looked it was leaking a bit on the top driverside corner, not actively leaking but a bit of corrosion where it had. So they want to replace the thermostat(covered under gm special coverage), the fan and radiator also replaced. From what I have read online this is a known issue with these radiators leaking at the seams. People end up replacing the radiator multiple times and still leaks. How can they get away with selling these cars with junk radiators and not recalling.

  The main instrument cluster where the speedometer and fuel gauge etc etc reside went blank during operation of the vehicle. I wasn't able to pull over safely until my destination was reached. Restarting the car seemed to "solve" the issue.

  The contact owns a 2021 Chevrolet Blazer. The contact stated that while driving at an undisclosed speed and making a turn, the vehicle lost braking functionality. The brake pedal was depressed to the floorboard. After exiting the vehicle, the contact became aware of a fluid leak underneath the vehicle. The "BRAKE Failure" warning light was illuminated. The manufacturer was notified of the failure. The vehicle was taken to a local dealer, where technicians diagnosed a fluid leak from the vacuum pump, causing the brake failure. The contact referenced NHTSA Campaign Number: 19V645000 (Service Brakes, Hydraulic) as a possible cause for the failure. However, the VIN was not included in the recall. The dealer replaced the vacuum pump, and the vehicle was repaired. The failure mileage was 120,000.

  Vehicle Information: 2021 Chevrolet Blazer 2.5L engine, VIN [XXX]. Odometer 118000 miles.Description of Incident: While operating the vehicle, the mechanical brake vacuum pump experienced a catastrophic internal failure. The drive gear housing shattered violently without warning, shearing off the end of the connecting engine camshaft. Because this was an instantaneous mechanical failure, the vehicles computer did not trigger any dashboard warning lights, check engine lights, or safe mode protocols prior to the failure.Safety Hazards and Component Damage: First, the total destruction of the vacuum pump caused an immediate compromise to the brake booster vacuum lines, resulting in a sudden, dangerous loss of power braking assistance. Second, the sheared camshaft breached the engine valve cover or head, causing the engines pressurized oil system to instantly dump all engine oil externally onto the ground. Third, shrapnel or violent structural torque from the instant engine seizure punctured or severed the adjacent transmission cooler fluid lines and compromised brake fluid lines, causing total loss of transmission fluid and brake fluid simultaneously.Request for Action: This failure mirrors the exact mechanical defects documented in GM Technical Service Bulletin 21-NA-268 and previous GM vacuum pump recalls like NHTSA Recall 19V-645, which excluded the 2021 Blazer. I am filing this report because the lack of an electronic warning indicator before a catastrophic mechanical brake and engine failure poses an extreme, immediate threat to highway safety. GM must expand recall coverage or issue a Special Coverage Adjustment for this model year. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

  My 2021 Chevrolet Blazer has experienced repeated problems involving the cooling system and is now exhibiting recurring symptoms that concern me about the vehicle’s reliability and safety. In 2023, the vehicle required a radiator/cooling-system repair. In 2024, it again required radiator/cooling-system repair, which was performed under warranty. The vehicle is now experiencing an abnormal humming/clicking noise from under the hood. The problem initially occurred primarily after rain but has become increasingly frequent. When the noise occurs, the air-conditioning system stops cooling properly and blows warm air. The check-engine light has also illuminated intermittently. The exact component currently malfunctioning is unknown. The vehicle remains available for inspection. Because the symptoms involve the engine compartment and follow multiple previous cooling-system repairs, I am concerned about the possibility of overheating, loss of proper cooling-system operation, an unexpected breakdown while driving, or another mechanical failure that could place the occupants or other motorists at risk. Authorized Chevrolet dealerships previously inspected and repaired the vehicle’s cooling system in 2023 and again in 2024. Despite those repairs, significant symptoms have returned. The current problem has not yet been definitively diagnosed, so I cannot state that the present failure is the same component previously repaired. The warning symptoms include the abnormal under-hood humming/clicking, loss of cold air from the air-conditioning system when the condition occurs, and an intermittent check-engine light. The symptoms have become more frequent over time. I am reporting this because of the recurring nature of the problem and the vehicle’s history of multiple cooling-system repairs. I request that NHTSA document and evaluate this complaint together with any similar complaints involving this model and model year.

  While idling in my driveway, the engine started to shake and the check engine light came on. Got it diagnosed and was told by a private repair center that we had lost compression in cylinder 4 and that it was not worth the repair and we needed to replace the engine. Got it towed to the dealership, Bill Fox Chevrolet, for a 2nd opinion and they confirmed what the private shop had said. Because the vehicle was well maintained with regular preventative maintenance, it was deemed the failure was not the fault of the owner. GM extended a goodwill warranty to help cover the cost of the engine replacement (70% coverage. We were 1 month and 2,000 miles past our warranty). They never told us root cause, only that it would have cost more money to repair it than it would be to get a new engine. The Blazer had been running fine up to that point and was my wife's main mode of transportation. The Blazer only had 62,000 miles on it when the failure occured.

  All 4 tires exhibit signs of dry rot impacting the inner sidewalls of each tire. The outer layer is showing significant signs of sidewall separation. There is no sign of damage visible on the exterior side walls, if an inspection was not done on this date 08/20/26 the driver and others would have been at significant risk of injury or death due to catastrophic failure. The worst separation occurred in the front drive / steering tires. While lesser damage was visible on the rear tire the damage was also significant. The driver side rear showed the least damage with only a 2 inch separation. The other 3 tires showed 12 inches or greater separation. Images are available for review.

  The thermostat malfunctioned causing an error message regarding “steering assist is reduced”. When I parked and turned off, the engine fan continued to run. When car was restarted, the temp gauge inside was stuck at C. Took to dealership and they assessed. They repaired the thermostat under power train warranty, however there was a crack in the radiator (top) resulting in the need for a new radiator. This vehicle had 35,000 miles on it. Upon research online, it seems there are MANY people who have had this same issue and worse. It appears cars produced during COVID era are most affected. Chevy refused to warranty the issue. The dealership offered a small cost reduction (due to our loyalty). The thermostat and the radiator issues seem to be well known by Chevy, they just refuse to accept responsibility. Now we are out thousands of dollars on a basically “new” vehicle.

  The vehicle showed an error on the dash which stated "Action Required Steering Assist is Reduced Drive with Care" I tool the vehicle to the dealer I purchased it from McClusky Chevy at Kings Auto Mall in Mason Ohio. They informed me that the error code is C0460:58 and GM has a service bulletin 20-NA-215 which advises to replace the Steering Gear due to internal component interference. No one explained to me that this could cause catastrophic failure and lead to a crash before I left the dealership. They could not replace it as they said they do not have the part and it is on national backorder. Additionally they told me the repair would cost me $3,400. The vehicle has 42k miles on it and this repair is not under warranty as the warranty that would have covered it expired in March of 2026. I have taken the vehicle to a different GM dealer - Tom Gill GMC in Fairfield Ohio - they are waiting on the part and I have a case opened with GM regarding the costs. You would think that if there is a risk of a catastrophic failure which could cause harm to my self or someone else - the dealer would have an obligation to tell me so before i drive off. If not legally, certainly morally.
