I WAS DRIVING HOME ON A COUNTRY ROAD ON THE EVENING OF JANUARY 21ST. THIS IS A NON-LIT, TAR AND CHIP WITH A SOFT SHOULDER ROAD. I HIT SOME BLACK ICE AND THE CAR SWERVED RIGHT, LEFT AND I GOT IT STRAIGHT AGAIN. DURING THE SWERVE, BOTH RIGHT AND LEFT AIR BAGS WENT OFF. I DID NOT HIT ANYTHING AND THE CAR NEVER LEFT THE ROAD. I MADE A CASE WITH GM. THEY DROPPED THE CASE BECAUSE THEY SAID THE VEHICLE NEARLY ROLLED OVER. I TOLD HER THAT I AM APPEALING THE CASE BECAUSE I WAS NEVER GIVEN ANY WRITTEN DOCUMENTATION AND IF THAT IS THE REASON THEY DROPPED THE CASE, THE REPORT HAS FALSE INFORMATION. THE VEHICLE NEVER NEARLY ROLLED OVER. I AM GETTING NO COOPERATION WITH GM. MY BRAND NEW VEHICLE IS SITTING IN A BODY SHOP WAITING ON AIRBAGS THAT ARE BACK ORDERED. HOW CAN A BRAND NEW VEHICLE HAVE PARTS ON BACK ORDER ALREADY? MY INSURANCE IS PAYING THE 11,000.00 REPAIR AND THEN WILL MOST LIKELY DROP US. I AM BEGGING FOR SOMEONE TO HELP. EVERY LAWYER I HAVE SPOKEN TO WILL NOT TAKE THE CASE BECAUSE THERE WERE NO INJURIES AND NO ONE WANT TO TAKE ON A MONSTER COMPANY LIKE GENERAL MOTORS.

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.

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

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.

EXTERIOR LIGHTING
1 Report0% of totalPreviewing the first 1 complaint summaries.
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.

I took my vehicle to the dealership for the recommended oil change on 09/15/2023. I am extremely good about keeping up on the routine maintenance. Upon arrival, the technician asked if I knew that my check engine light was on. I stated no, it was not on during my drive in and has not been on previously whatsoever. I scheduled a diagnostic for 09/20/2023 and brought it back to the dealership with 68,191 being the mileage. It was determined that my thermostat needs to be replaced. I then began receiving the message Steering Assist is Reduced" which is very unsettling. I am finding that a lot of newer model 2019+ Chevy Blazer owners are struggling with the exact same temperature issue, even those with way fewer mileage than mine for example a person who just had 25K on theirs. This needs to be taken more seriously / addressed further by the manufacturer.

When attempting to put my car in PARK, the car issues a warning stating the car is not in PARK, it doesn't recognize the gear shift being in park, therefore, I am unable to shut my car off or lock it up. It is a known manufacturing defect and GM refuses to cover the cost to add a bandaid to it as there is no permanent fix. This is a safety issue, and now my car is not reliable, nor safe. GM refuses to issue a recall on this.

LANE DEPARTURE: WARNING
1 Report0% of totalPreviewing the first 1 complaint summaries.
1. Wire harness with coil wires is the problem. It was fixed by a local shop and the vehicle can be inspected if needed. 2. The car throws a code for a faulty thermostat/coolant temp sensor. This will not allow the car get to oporating temp and could cause engine damage or not perform properly causing risk of an accident. Also this will reduce the driver assist features such as lane assist and adaptive cruise/braking. 3. Yes. 4. A local shop inspected the thermostat and coolant temp sensor and they oporated as they should. 5. The engine light comes on for the reasons mentioned above. It also has a "driver assist reduced" message. It appeared randomly while driving and stayed on for multiple days. Vehicle had a code for a bad thermostat/coolant temp sensor and "driver assist reduced" message. The cause is NOT the temp sensor or thermostat and is actually a wiring harness that two wires need to be separated from the bunch. The frequency from one wire interferes with the coolant temp sensor wires. I am on several forums for chevy blazers and there are TONS of posts about this issue with the 3.6 V6. Most people will go in and have these expensice parts replaced. It is not acceptable to have people get charged for a $800+ job when the part is not faulty.
