general problems of the 2022 Chevrolet Blazer

I am reporting a severe powertrain safety hazard involving my 2022 Chevrolet Blazer at approximately 69,000 miles. The vehicle's 9-speed transmission is experiencing a critical internal hydraulic failure that causes unpredictable and violent lurching. Specifically, there is a severe delayed engagement when shifting into reverse. The engine revs without moving until the hydraulic pressure suddenly spikes, causing the vehicle to violently slam backwards and catch the gear. Furthermore, the transmission exhibits harsh and slipping shifts while driving forward, specifically violently jerking during the 2nd-to-3rd gear upshift. ?these exact symptoms align with widely documented hydraulic control and valve body defects in the gm 9t50/9t65 transmissions, which are known to cause harsh shifts, delayed engagement, and flaring between gears. Concurrent with these transmission failures, the abs warning light illuminated. An independent shop misdiagnosed the severe drivability issue as a standard abs fault, while a local Chevrolet dealership denied goodwill assistance despite this being a premature internal transmission failure. ?this creates a severe safety hazard. The unpredictable lurching in reverse endangers pedestrians and other vehicles in parking lots. Additionally, the violent shifting at speed creates a high risk of sudden internal component failure and a complete loss of propulsion while driving in active traffic.

I have been smelling engine coolant for some time and found a leak on the drivers side top seam where the aluminum meets the plastic tank on the radiator. This is a known problem with 2019=2026 chevy Blazers by gm and it still hasn't been resolved. After researching, I have found numerous Blazer owners that have this same issue and some are on 3rd and 4th radiator replacement. I am afraid to drive the vehicle due to the leak that could leave me and my family stranded on the side of the road. I am also concerned about a major leak or seam separation that could allow a large amount of coolant out that could get on the tires and cause loss of vehicle control as a result. Also, the leaking coolant is a hazard to any animals that are around as the coolant puddles under my vehicle after driving. At this point, the Blazer is running hotter and I had to add coolant. I just called to price a new radiator. . . $450 and install. . . $1,025. . . That isn't a cost I should have to take on with gm knowing about this issue for years.

While driving on the road at/or about 45 mph to my workplace, the transmission gave out and lost forward momentum. I had the transmission serviced for its second serivce at 84705 miles just ten days before this happened. The first service occurred around 47k miles when I learned about this issue with Chevrolet transmissions.

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.

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.

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.

Temp sensor quit working. I have seen online there are tons of people having this exact problem but no recalls issued.

2023: 16k miles, the Chevrolet Blazer in questions transmission went out; thus requiring it to be brought into the dealership for repair; it was "repaired" and given back to us. A few days after said repair, I was driving it with my son in the vehicle, and the transmission went out while on the highway. I was almost hit from behind as I limped it to the side of the road. A brand new transmission was put in. During this time, there was also issues with the brakes where they were making noises. 2025: Blazer check engine light came on. On the way to get it diagnosed, it began to overheat; we were limping it to the side of the road when it stated "engine overheating, vehicle turning off". The safety system for shutting down when overheating worked, however, I was in the roaad again. Thus putting me in danger of being hit. We just received notice from the dealership that it is (as of this moment) a cooling fan, ac pressure switch, thermostat, and a cracked radiator. We are waiting on the technicians to finish checking it to see if there are any other issues.

The engine fan has been running and the check engine light has come on and upon further inspection I discovered that this is a common issue with this vehicle. I have had my vehicle inspected and serviced by Chevrolet since I purchased it and I informed the technician that there was water under my vehicle if it ran idle on several occasions and was told that it was a non issue and now that my vehicle is out of warranty there is an issue with the same thing I have been concerned about.

My transmission started slipping really badly. Had never happened before, and then suddenly wouldn’t shift above 3rd gear. My reverse gear stopped working. I had to have my valve body replaced which fixed the drive gears but the reverse still didn’t work. After months without my car, my dealership had to replace the transmission.
