2023 CHEVROLET SUBURBAN Complaints

The 2023 suburban started shuttering on idle and loosing power on drive due to a misfire in bank 4, the fuel injector was changed, but the problem persisted. And now the dealer says that I need to change all 8 injectors. 2900 job on a car with 54000 miles. Crazy

The engine seized while I was driving. The dealer discovered a crack in the engine block, which caused the oil to leak out. Unfortunately, the warranty had expired at 60,000 miles. The dealer replaced the engine with a brand-new one. So, I had to cover the full repair cost of approximately $6,830.29 out of pocket.

My 6.2L V8 engine blew up while I was driving across bridge and I barely had enough time to get it off the road out of traffic.

I was driving my family to San Antonio for a vacation when the vehicle suddenly stopped working. The display read restart engine but the car just abruptly stopped and I was forced to pull to the side of the road. Once the car came to a complete stop the car shifted into park and could not shift out of park. The car would not start, display would read conditions not met? I had to have the car towed to the dealership. They are giving me a hard time.

Driving on the expressway my vehicle would not accelerate over 53mph. I then noticed the vehicle losing power where I then had to pull over onto the shoulder. The vehicle lost power and would not restart or go into neutral. Ultimately the vehicle had to be towed

My 2023 High Country Chevrolet Suburban's V8 6.2L engine failed 6 hours from home while our family was en route to Colorado. It was towed to the closest city and the dealership informed me the engines are on a nationwide backorder and it could be months before one is made available. The dealership stated that GM will not release information as to where the customer is on "the list" of recipients. My car has 44,000 miles and is well maintained. It has been in the shop for other repairs - suspension issues, tech package problems (wifi, onstar, google and navigation not working properly). Spoke with GM representative and was told if the engine makes it onto the recall list the repair will be expedited. Not sure how that is possible with so many engines failing. Maybe GM/Chevrolet will be forced to increase production.

Middle of engine started making a tapping sound. Went to closest dealership service department. They said it was most likely an issue with the valve train but we should be able to get home. Within 10 miles, the engine completely seized up while on the highway loosing all power. Was able to get to the side of the highway. Towed the vehicle to the dealership that we bought from. They said it was going to need a new engine just as soon as they could find one.

6.2L L87 Engine Failure with 36,000 miles on it. While driving on the highway and attempting to pass another vehicle that was traveling on a 2-lane highway the car suddenly died, and the transmission shifted into neutral. When I noticed the vehicle would not accelerate, I looked down and saw the push to start warning and tried to restart the vehicle with no response. I had to allow the vehicle I was passing to get ahead of me before I could swap back into that lane to get out of the way of oncoming traffic eventually coasting onto the side of the road to a complete stop. The vehicle I was passing slowed down after the engine died not knowing what I was doing and drove right beside me blocking the lane until I signaled for them to go ahead so I could get back into the lane. If the vehicle in the oncoming lane had not slowed down to allow me time to get back into the proper lane a head on collision would have occurred. This 2023 vehicle was purchased used 14days prior from a GM certified dealership and had no warning lamps on the dash and showed no indication a failure was about to occur. The vehicle was driving perfectly normal until the failure occurred. Once the vehicle was towed to the dealership it was determined the engine had failed due to crankshaft bearings. The dealership explained there were no available replacement GM engines and could possibly be a lead time of 6 months before a replacement engine could arrive. I purchased the vehicle for $60,000 and the engine fails 14 days later and now I could be without a vehicle for 6 months and the dealership did not have any loaner vehicles available.

I pulled into a parking spot and the car died right before I shut it off. I came out and restarted it to leave and it backed up about 5 feet and died and would never start again. There was never any prior indication that it had any problems. I bought it new and always had a Chevy dealer do the required maintenance. I was told today that it would need a new engine because the engine has seized up; however, until they do a full tear down of the engine, they said they cannot tell me exactly what has cause the problem. I have heard of others having problems with the 6.2 engine so I thought I would report it. I don't have any paperwork yet from the dealer to upload.

Engine failed while driving on highway. Would not restart. Towed to Chevrolet dealer who determined engine full of metal debris requiring total engine replacement.
