ENGINE
Brand new 2023 suburban radiator ruptured at 14,000 miles. Radiator and hoses replaced April 2024 and the car has ongoing issues since then. Most recently the car has a strong coolant smell and the dealership states they cannot find a leak or source of the smell. I have worked with 2 different dealerships on this matter. I was told that the radiator was a “poorly manufactured part” when it originally ruptured. No safety warnings ever appeared even when the oil was dripping out of the bottom after the original rupture. Oil and coolant had mixed in the coolant reservoir and no warning light ever signaled. The most recent coolant smell poses a safety risk to my families respiratory system as the manufacturer states they cannot find the source of the smell and have tried to return to vehicle to me twice with the strong odor coming out of the vents. We have had the coolant reservoir flushed several times as oil remains in their, hoses replaced, and ongoing service visits for a year for the same thing since the original rupture in April 2024.

ENGINE, FUEL/PROPULSION SYSTEM
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.

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.

ENGINE
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.

ENGINE, POWER TRAIN
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.

UNKNOWN OR OTHER
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.

[XXX], driving on [XXX] at mile marker [XXX], 4 miles east of Moorcroft, Wyoming, the vehicle lost power and engine quit. We made it to the side of the road and vehicle would not start. The temperature was negative 5 degrees. With cell phone service, we were able to secure a ride and a towing company before we got extremely cold in the car. The vehicle was towed by Manning's Towing of Gillette, Wyoming to White's Frontier Motors, 444 Skyline Drive, Gillette, WY 82718. After 10 days in the shop, the service department diagnosed the engine was inoperable and the vehicle would need a new engine. There was no indication of the engine failure prior to its failure. To date I have had 15 communications with the service department at the dealership and GM Motors with no resolution or date of repair.

In October 2024, the vehicle just shut off while we were driving down the road. Had to pull off to the side and got it going after about 5 minutes. Couldn't get the vehicle to replicate the problem so nothing chevy could do. No check engine light. No codes were given. On January 4th the vehicle started making a horrible noise. But then stopped making the noise on January 5th. Called Olympia, Washington Chevrolet to get it in to be looked at. Soonest appointment they had was February 5th. I made the appointment. February 11th, the engine seized and quick working completely. February 13th, had the vehicle towed to the nearest Chevrolet. Getting the vehicle into neutral and on the tow truck was terrifying. Makes me question the transmission. My vehicle has been at Chevrolet since January 13th. Today is March 11th. I do not feel safe driving this vehicle once it does get fixed. It has left me stranded twice. Once when it just shut off and another when it actually broke down for good.

I was on [XXX] in Athens, Ga. Going about 65mph in the left lane, casually passing a slow truck. it was rainy, in a construction zone, heavy traffic. With no warning lights or indication there was a problem the engine suddenly died and shifted itself into neutral. I had just started going up hill, no left lane median but I managed to barely make the right shoulder, when the vehicle came to a stop it shifted into Park, from that point forward the vehicle was locked down. I was so close to the traffic I had to fold the drivers mirror. I literally sat on the passenger side of the truck with my seat belt fastened because I expected to be hit. Took about 1.5 hours for tow truck. The tow truck driver was nearly hit trying to load the truck, several accidents were narrowly avoided by people trying to move over. Truck taken to Auto Gallery Chevrolet in Commerce GA, after three weeks they confirmed the engine had to be replaced and it would be done under warranty. I have not been told the exact nature of the failure, but they did confirm the engine could not be rotated. They could not tell me how long it would take to find and engine but there was another vehicle with the same issue that was ahead of me. To the best of by knowledge Chevrolet has accepted the failure report completed by the technician but have not otherwise engaged. I have not been provided any documentation from the dealership.

Without any warning driving 65 mph down a freeway the suburbans motor totally shut down. We had to cross over 2 lanes without getting hit by all the traffic. No dashboard lights ever came on until after we got onto the shoulder and sat there for an hour then the check engine light came on. We got stranded 2 hours from our vacation spot in AZ and now we’re stranded 1,600 miles from our home in MN. After 5 hours in the middle of the desert the tow truck finally showed up and towed the vehicle to Sands Dealership in Surprise AZ. We have never had any other problems before this happened. Never thought At 2023 vehicle with 30,000 miles would blow Motor. Waiting to hear from GM on what our options are to get it fixed and get us back home!

I was cruising at 45 - 50 mph and the vehicle went into NEUTRAL, shut off, would not restart, and would not shift into drive. I pulled into a Publix. I pressed the start /Stop button and the dash turned off. I turn pressed the brake and pressed the ignition button and the Suburban started up. Drove out of the parking lot and began accelerating when the vehicle shut off again. I could not restart the vehicle. I was able to coast into a gas station parking lot, but half of the vehicle was sticking out into the road. The vehicle would not go into neutral and would not start. The vehicle was towed to Palm Chevrolet in Ocala, Florida.

I was driving on [XXX] in rural Montana (zero cell phone coverage) on [XXX] (freezing weather, snow packed roads). Without warning the suburban just shut down. It seemed to still have "power". interior lights worked ect. but the engine just died. I tried to pull mostly off of the road but I couldn't get it entirely off of the road because of the snow pushed off of the road by snow plows. I tried to restart the vehicle several times but it would not turn over. I assumed it was an electrical issue at the time. There was zero warning that there was any engine issue. When a mechanic finally had the opportunity to look into the issue he told me the engine has seized up. I had to walk several miles in the cold hoping to get cell phone service to get to a place to warm up. I also couldn't get the vehicle off of the road and I was sure the vehicle was going to be hit or cause an accident on the narrow highway.

Traveling at high speed on major highway and engine stopped. Unable to get car restarted and in fact the instrument panel and information center blanked out. Was forced to have vehicle towed approximately 60 miles to purchasing dealership for diagnosis. Dealer indicates engine is seized and will require replacement. Vehicle has had excellent, verifiable, maintenance record. We have owned this vehicle for approximately 18 months and currently has approximately 62,000 miles. Upon research, I have learned that our vehicle is not the only GM product to have this premature failure.
