2022 Chevrolet Blazer

The contact owns a 2022 Chevrolet Blazer. The contact stated that the coolant was leaking from the radiator. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was diagnosed and determined that the radiator needed to be replaced. The contact was informed that the dealer was replacing a lot of radiators for similar failures. The vehicle was not repaired. The manufacturer was contacted, and a case was opened. The failure mileage was approximately 49,500.

Car stalled and told me to put in neutral. Could smell gas. Car wouldn't come back on. Code u18a2 (lost communication with fuel pump communication module), part is available for inspection, we were all at risk due to the car stalling on the highway with no prior warnings, check engine light came on after car stalled, ordered new part from GMC, fix the issue right away. This part has been recalled on other models just not on 2022.

BROUGHT MY CAR TO CHEVROLET CENTER IN WINTER HAVEN FLORIDA BECAUSE I HAD 2 DIAGNOSTIC CODES SHOW UP WITH A CHECK ENGINE LIGHT, THE CODES WERE (U1345: Indicates a communication fault on the LIN (Local Interconnect Network) Bus, usually tied to modules like the active grille shutters, cooling fans, or charge air cooler (CAC) pump.U0632: Indicates lost communication specifically with Cooling Fan 1.) THE DEALERSHIP TOLD ME THEY DIDN'T FIND ANY CODES IN THE SYSTEM AND THEY TRIED TO CHARGE ME $165 FOR A DIAGNOSTIC FEE. RIGHT AFTER I LEFT THE DEALERSHIP I WAS HAVING THE SAME CODES POP UP, WITH THE CHECK ENGINE LIGHT AND MY CAR WAS OVERHEATING. CHEVROLETS ECM/PCM WARRANTY IS 8 YEARS OR 80,000 MILES.

Thermostat fails resulting in steering power reduced, temperature goes to C and fan runs overtime. This thermostat or temp sensor fails intermittently and fixes itself. Car could be overheating and you wouldn't know. This part is recalled on 2021 Blazers already.

I have a 2022 Blazer with a 3.6 engine. The thermostat has failed and dealer says only certain blazer vehicles are covered under aspecial warrnty exstesion. I know several people having the same problem.I have a check engine light, with a scan shows code P0128(thermostat0. I also have a display of power steering assist reduced and tempature gauge stays much lower than normal.. When you turn vehicle off the high speed cooling fans remain running ub=ntil battery is dead.

I have received this warning a few different times “Steering Assist is Reduced". Which causes my vehicle to not blow cold air when AC is on. Fans are louder than normal. And when I turn off my vehicle fans continue to run for roughly around 8 minutes.

My engine coolant temperature sensor failed. Replaced it and still not fixing the issue. This takes my steering assist away as they are all interlinked? I have seen on forms this is a common issue. This has the potential to blow up my engine, I’m not sure how this is not a recall with so many 2020-2026 blazer owners having the same issue.

My Drive Assist stopped working. Then my Air conditioning stopped blowing cold. Then the temperature gauge stopped working. Upon turning the car off the fan continued to run for several minutes. Took to repair shop where it required a new thermostat housing, coolant temp sensor and coolant flush. The total cost for repair was $1,131.52. The car has 37,000 miles on it. Barely out of warranty. This is a well-known issue among Chevy owners.

When shutting off the car, the fan continued to run. I started the car up again to see if this would allow the fan to turn off. No luck. The steering assist was dis-enabled on the dash. I took my car to the dealer to find out that it has a bad thermostat and that my radiator was leaking. The thermostat was covered but I had to use my extended warranty to pay the additional repair. My deductible for my extended warranty is $300.00. My daughter has a 2021 Chevy Blazer and the same situation happened. There was a recall and all her parts were covered.

Transmission completely failed while driving at highway speeds.

Driving the vehicle when all of a sudden the engine shut off. All electrical systems continued to function. Luckily this occurred at low speed in a parking lot but had it happened at high speed on the freeway it could have been a huge safety risk. The vehicle was towed to a nearby automotive shop that diagnosed it as a bad fuel pump controller. There is an open GM recall that includes the 2021 Chevy Blazer (and a suite of other GM vehicles), but not the 2022 Chevy Blazer. I am concerned that the GM recall does not fully cover all of the vehicles that could be impacted by this issue. Date: September 11, 2025 Subject: N252516900 - Emission Recall Fuel Pump Power Control Module [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Unknown…. Cut open my shin (leg) on the bottom corner of my driver’s door (black plastic side molding). That part is sharp! Required ER with 14 stitches on 9-24-25. As of today I’m still recovering.

Car is displaying a “Steering assist is reduced drive with caution” engine light is on and fan continues to run for 5-8 minutes after car is turned off. Was told by a mechanic it is a P0128 code, coolant thermostat. This is the third time it has happened in the last year. Other two times the codes cleared.

Incident Description: While my wife was driving our 2022 Chevy Blazer at approximately 40 miles per hour, the vehicle’s dashboard suddenly went dark and became unresponsive. Multiple warning lights illuminated simultaneously, including the check engine light, ABS light, and other system alerts. The dashboard appeared to flicker as though it was repeatedly shutting down and restarting. When the brake pedal was applied, it offered no resistance and traveled completely to the floor without slowing the vehicle. To bring the vehicle to a stop, my wife shifted into neutral and allowed it to coast until it came to a complete stop. Fortunately, there were no intersections or other vehicles in front of her at the time, preventing a potential accident. This incident raises serious safety concerns, as both electrical and braking systems appeared to fail simultaneously.

Put my car into park and the fan kept running continuously. I noticed that the engine temperature gauge did not move off of cool either. When I drove it, I got an alert that the ‘steering assist was reduced’ and shortly after my check engine light came on. My safety was at risk due to the fact that I couldn’t monitor my engines temperature and it very well could have been overheating and I would’ve never known. I took it to the dealer and they did confirm that my thermostat was stuck open and wasnt allowing my engine to get up to temperature. My ecm module had to be replaced as well. The mechanic said, had it closed my engine would’ve overheated with no signs until it was too late.

Control arm snapped on the I-71. Going 70 miles an hour when it happened. Definitely could have been a major accident but luckily no cars were around us when it happened. i rode over a bridge's transition and heard a big pop like a tire. Then it sounded and felt like we were riding on a rim. When we got out we saw what had happened. No warnings or anything before this happened.

Automatic transmission and radiator. Vehicle shifted hard and then would not go to a higher gear after pulling out into an intersection. Vehicle was pulled over to side of road and shut off. Restarted and tried to merge back onto main road and while trying to accelerate, the rpm’s went over 3500 quickly and wouldn’t shift once the vehicle hit 30mph. The engine light came on. There has been no previous engine lights or issues. Scheduled an appointment at a Chevrolet dealership and had the vehicle towed on a flatbed trailer to be looked at. I stated that there was a major problem/issue with the transmission and explained the problem. In their notes it states they took it for a test drive before even checking the transmission fluid for metal particles. I told them it was a severe failure and was barely drivable. It was able to drive up in the trailer to be towed, but never shifted out of 1st gear. We are a little over 64,000 miles and the warranty cut off is 60,000. The dealership states that the transmission needs replaced and the cooling system as well since metal particles made it into that system as well.

While driving, the vehicle displayed a “Service Power Steering” warning message, and shortly after, the steering became noticeably heavier and less responsive. The issue occurs intermittently but has worsened over time, creating a serious safety concern because loss of steering assist could occur at any speed. The dealer diagnosed the problem as a failure of the electronic power steering module and rack-and-pinion assembly, quoting an estimated repair cost of approximately $2,500. The vehicle has only around 56,000 miles and has been maintained as recommended. The dealer confirmed the issue but stated that General Motors would not cover the repair under warranty or goodwill assistance. This defect poses a significant safety risk, as a sudden loss of power steering assist can make the vehicle difficult to control, especially during turns or emergency maneuvers. There were no accidents or injuries, but the potential for loss of control is high. The warning message and loss of assist can be reproduced and have been verified by the dealership. The vehicle has not been repaired yet, and the defective parts are available for inspection upon request.

Increasing speed by itself, let foot off gas pedal and gas pedal sticking, 1st time I tapped brakes and it quit. 2nd time it did not. I had to slam brakes and hokd until the point they had overheated and smell burnt and filed a separate complaint for that today. Gas pedal sticking and self accelerating. Pedal to the floor accelerating. I do not drive like that and scared the hell out of me. I bout it 5 days ago from a Chevrolet dealership. I'm tired of rip offs. Next one best be brand new and they reimburse me for outside mechanical I inspection period. Bc I trust no dealer now. Went from 7p to about 95 in 10 seconds for 10 min. Not sure what braking did bx I coukd care less about the phone whike I am trying not to hit cars in front of me literally almost jammed an 18 wheeler and moving truck with me pushing the brakes as gmhard as I could.

Accelerating without pressing gas pedal and gas pedal won't release with braking. Brakes overheated and this went on 10 minutes before I got it to release the gas pedal so I could safely stop. I almost hit 4 vehicles on the interstate because the gas pedal went to the floor all the sudden.
