2019 Chevrolet Blazer Problems

Shift to park sensor Shift to park warning. It was reported to dealer

Electronically controlled thermostat and sensor fail or get stuck at a much lower coolant temperature causing the dash to display the “steering assist is reduced drive with care.” It isn’t just a message, the steering is much harder to use potentially causing an accident. The ac completely doesn’t work causing potential for sensitive, elderly, or young children and pets to overheat inside, it’s significant risk of injury or death from the hot summer temperatures. The engine coolant temperature gauge is all the way down on C position which isn’t registering how hot/cold the engine gets potentially causing damage to the vehicle and a total loss of the vehicle entirely due to damage from the engine overheating. GM sent out letters to 2021 blazer owners which included a special coverage number N252508350 applying to people with this year having this problem and they have until 2036 or 150,009 mi to get the repairs made free of charge, they just bring the document with the special repair codes to the dealer and they fix it free of charge. After doing research online, this problem is affecting all years of the 2019+ blazers with the 3.6L V6 engine AND other known problems with other models and years of their other lineup of cars, it’s very widespread across their platforms. So what are people supposed to do when it isn’t the 2021 year? Pay an $800+ repair bill to GM when they KNOW it’s more widespread than just this year/make? This is a scam. I can’t even do the repair myself because I’m having trouble finding the correct parts online and not only that the repair is extensive, the whole top half of the engine needs to be taken apart just to get to the thermostat, we’re talking the airbox and intake manifold, all the plastic parts and shrouds and sensors covering engine, the fuel rail and injectors, pipes and clamps, engine coolant needs drained and refilled. It’s a major fix. I’m reporting this complaint to raise awareness and hopefully GM will do the right thing.

Shift to Park issue: Known issue where the car fails to recognize it is in Park, preventing it from shutting off. Electronics: Potential blanked-out display screens, USB port issues, and malfunctioning cameras. Steering Assist: Restricted, temperature gauge goes to cold and radiator fan blows hard. I have to unplug negative cable to battery and reconnect and everything goes back to normal.

The vehicle will not shut off when you shift to park. You are forced to sit in the vehicle for extended periods of time attempting to get the vehicle turned off. Apparently Chevy is familiar with eat problem and there are pending class action law suits in Ohio. According to the dealership Chevy has acknowledged there is a defect but no recall has been issued. We have had this issue for about two months and it is getting worse.

Power steering goes out intermittently while driving.

The transmission or torque converter has slippage and shuddering that has caused one or both to go bad. My safety was at risk due to this item beginning to fail to cause the inability to accelerate to maintain my position in traffic. The problem was recreated for the service technician. There was no warning or indication before this became an issue.

My vehicle is breaking on its own. There are other vehicles riding behind me and it just stops out of nowhere. I think that's dangerous. I can be driving and I'm thinking I'm OK driving in a vehicle. Just just hit on break. I don't know where I just stops and while I'm driving and I think that's very dangerous

We are noticing the coolant meter seems to be stuck on C, the AC is not blowing cold and we are getting a message that ACTION REQUIRED steering assist is reduced, drive with CAUTION. Today the brakes slammed on by themselves and almost sent my wife thru the windshield. Luckily she was in a clear area with no other cars around.

When the vehicle is in park and you try to turn it off with the start/stop button an on dash error code of ‘Shift to Park’ appears even though the vehicle is clearly in park. You are not able to turn the vehicle off. This currently is forcing me to restart the engine, put my car in reverse, shift back in drive, try re-parking and turning it off again, repeating the process until it eventually turns off. I do not know if my car is truly in gear or not. I’m afraid that it might cause a dangerous situation. GM has already identified this recall for other VINs of 2019 Chevy Blazers I believe it should be extended to additional VINs.

The contact owns a 2019 Chevrolet Blazer. The contact stated that the gear shifter had repeatedly become loosened, causing the gear shifter to move in a circular motion while in park(P). The contact stated that the "Shift to Park" message was displayed while the vehicle was in park(P). The contact repeatedly struck the back of the gear shifter while in park(P) to correct the failure. The gear shifter had been replaced on four separate occasions. The contact stated that the first three failures were repaired under warranty; however, the contact recently had to pay out of pocket for the last repair. The contact stated that the failure had returned. The manufacturer was notified of the failure but offered no assistance. The failure mileage was unknown.

The sensor or cable mechanism that tells the vehicle when it has been put in park is malfunctioning. It is not allowing me to park the vehicle correctly and forcing me to start and stop the car multiple times before registering that it is in park. Sometimes getting very frustrated and slamming into Park. I have seen many complaints about this error. The vehicle has less than 65,000 miles. This needs to be looked into and fixed by a recall. We've been very loyal to the Chevy brand and I believe we should not have to pay for the cheap part GM used and should not be failing within 3 years of purchasing the vehicle.

i was in a severe accident on 10/6/2025 with a vehicle traveling at approximately 50+mph. My front quarter panel was struck crossing an intersection when a vehicle ran a red light. My vehicle sustained a lot of damage with my head striking the drivers side window --- with no air bags deploying

WHILE DRIVING THE VEHICLE, AN AIRBAG ALERT GOES OFF RECOMMENDING SERVICE. IT DOES NOT MATTER WHAT SPEED I'M DRIVING, OR NECESSARILY THE WEATHER. BUT IT DOES TEND TO GO OFF MORE FREQUENTLY IF IT'S HOT OR COLD OUT. I HAVE BROUGHT THE VEHICLE IN FOR SERVICE, BUT THEY CAN'T SEEM TO FIGURE IT OUT. ALSO, WHILE DRIVING, AN ADAPTIVE CRUISE ALERT GOES OFF AT TIMES. I HAVE SERVICED THE VEHICLE AT LEAST THREE TIMES FOR THIS. IT IS HAPPENING LESS, BUT STILL HAPPENING.

I purchased this vehicle on June 26, 2020. When the vehicle was serviced on May 13, 2021 it had 8,366 miles on it and the tread wear was recorded at 6/32". In late June/early July 2021, I noticed the rear end of the vehicle seemed to slide around corners which lead me to research on the internet the Michelin tires that were on the vehicle. I found a GM Service Bulletin 19-NA-078 dated January 2020 that found issues with these tires. The vehicle's alignment was fixed and that problem seemed to go away. The vehicle was serviced on October 29, 2021 and I was told new tires were needed before winter driving. The tread measurement was 5/32". I told the service department that I wanted to talk to Michelin about this because I felt their tires should last longer. On October 29, the vehicle had 13,332 miles on it. I spoke to a Michelin representative on Monday, November 8th after scanning and emailing in the service records from October 29th showing the tread measurement to be 5/32". The Michelin representative acknowledged that they did have the service records and the only thing needed was a phone call from Bergstrom - Middleton WI, an authorized Michelin dealer. Bergstrom was confident additional information would be needed on the tires and asked that I schedule an appointment to come back in with the vehicle. I did that today. Today I was told by Bergstrom that nothing could be done because the tires were at 5/32". The current mileage on my vehicle is less than 14,000 miles and all 4 of these tires need to be replaced. It appears from what I could find on the internet, a "safe tire" is one that has at least 6/32" tire tread so these tires, which I might add should not have worn out at 14,000 miles, are no longer safe. What boggles my mind is that this has been a known issue with these tires since January 2020, before I even purchased the vehicle. I feel mislead and given the run-around by GM and Michelin. Consumer stated Michelin has agreed to cover 70% of new tires. Consumer would like to clos

I bought a 2019 Chevy Blazer in February 2023 . The vehicle has issues when I fill it with gas. As soon as I gas up to full it starts jerking immediately afterwards. It makes loud popping sounds. The engine dies completely. It starts to tremble and will not go. When I try to turn in back on , the starter works very hard before it will turn back on. It does turn back on eventually but I have to pull over to the side and accelerate the engine until it finally stays on. I drives that way turning off at lights and stops. After about 10-15 minutes of this , it finally stays on long enough to drive another 20 minutes or so to get home. After it rests for a few hours, it goes like normal. This is a big safety concern for me since these episodes happen every week when I fill up my car with gas. I have almost been hit from behind during these episodes and it is very scary and such a hassle to have to deal with this every week. I have already had several Chevy dealers and mechanics work on this problem and it continues to act up like this. I have all the paperwork for the work that has been done. $15, 000 have already been spent on this problem and the problem still continues. Please help me. I like chevy vehicles and have always bought chevy but this is the second chevy vehicle that has given me problems when I gas up. Please look into this problem. My phone number [XXX] if you need to make contact with me by phone. Thank you [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

1. The power steering (confirmed by dealership) is causing vehicle to pull very hard in one direction 2. Something fuel related does not allow my car to accelerate properly. Foot will be on the throttle and accelerating and without moving the throttle the vehicle will slow, RPMS will drop then suddenly begins to accelerate again. 3. Car states it’s not in park after I shift into park.

1.The vehicle does not recognize it's in park periodically and will not shut off 2. Thermostat housing and thermostat failure 3. Tint covered chrome on exterior of body peeling off Only had the car 3 weeks Currently at dealership repairing thermostat out of pocket

The contact owns a 2019 Chevrolet Blazer. The contact stated that they began to notice the grill at the front of their vehicle begin to flake slowly over time. The flakes had grown to the size of a dime. The vehicle was taken to the local dealer, where the contact was advised that the dealer would cover half of the cost to replace the grill. The vehicle was not repaired. The manufacturer was notified of the issue.

The contact owns a 2019 Chevrolet Blazer. The contact stated that whenever it rained, water would leak into the vehicle from the gasket around the sunroof. The headliner would catch the water and disperse water down the interior pillars, forming puddles in the front and rear passenger’s floorboards. The contact had not taken the vehicle to a local dealer or independent mechanic. The vehicle had not been repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 40,000.

The front passenger seat belt was not clicking in. There was no damage done to the seat belt it just stopped working. The car is only 3 years old the seatbelt should not fail this is a safety issue. I had to pay $366 to fix it at the dealer. They said it was no longer under warranty and since there was not a recall they would not pay for it.

My complaint is with the standard HID headlights in the 2019 Blazer and the very poor mounting system. The headlights are mounted TOO LOW to be effective in lighting the roadway, particularly where no shoulder stripping is on the roadway. Too, at unlighted intersections the lighting so poor that safe left or right turns cannot be accomplished. The HID lights themselves are a poor design in that they do not offer any useable peripheral lighting to add vision to the road shoulders. Due to the low mounting, the HID do not adequately shine light onto the road surface. Rather the available light shines across the surface and not down on it had the lights been mounted at the top of the fenders as most lights are mounted and designed. This has been an ongoing issue with the vehicle since purchasing the car new in November of 2018.

Snow/Ice build up inside tire rim's, causing improper tire balance. And also brake to freeze up when vehicle is parked, during driving in winter snow conditions. When driving on interstate roads at speed limit, the vehicle start's to shake a lot , like a flat tire. I talked to a Chevy dealer service manager about it and he said that their wasn't any safety massage out on that problem. I've never had a wheel snow/ice up like that before !! So now during the winter I check and clean out the snow/ice out of the wheel rim to prevent the vibration and driving problem. No warning light came on. It just shook the car real badly while driving on the highway.
