Loud ticking/ knocking sounds and loss of power. At ideal vehicle would severely shake. Check engine light did come at time of failure. Both times the failure occurred during acceleration from a stop to approximately 40mph.

ENGINE
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!

POWER TRAIN
Catastrophic transmission failure while driving on highway trip with family. Thankfully did not completely lock up drive train, but such a catastrophic failure could have caused a transmission/engine lock up leading to a serious accident. Drove to nearest Chevy dealer (Everett Chevy Morganton NC), inspected, validated catastrophic transmission failure. Vehicle towed back to Hendrick Chevy Monroe NC. Hendrick confirmed catastrophic transmission failure, required complete transmission replacement. I requested failed part evaluation/warranty review. Escalated to Chevy customer support. Hendrick replaced transmission 1/29/2025. Hendrick upgraded to new Thermal Bypass Valve per service bulletin #21-NA-199 as part of complete transmission replacement. Vehicle was serviced previously on 11/1/2025 for routine oil change and inspection, with transmission noted as "good." Onstar monthly diagnostic for December 26, 2024 indicated engine and transmission system "good/OK".

AIR BAGS
This is not connected with a specific crash in this vehicle. It is a defect with all vehicles with this seat. There is known common defect with the stitching on the side of the front seats covering the airbag. The stitching is designed to come apart if an airbag is deployed. The defective stitching deteriorates and falls apart. This exposes the airbag system in the seat. This occurs on all GM vehicles with the same leather seats. Models include Suburbans, Yukons, and pickup trucks. In this Suburban the stiching started to come apart about 6 years ago with a few loose threads. The entire side of the seat has now come apart. The rest of the seat is in relatively good repair without any holes, rips or torn stitching. GM claims this is cosmetic and not covered. The safety issues caused by this includes the potential deterioration of the airbag system interfering with deployment in a crash. Another safety issue is the potential for foreign objects to get lodged in this space and injuring someone if the airbag goes off. The third safety issue is the potential of a person, or child, to access the airbag and cause it to go off without warning.

SERVICE BRAKES, ELECTRICAL SYSTEM, BACK OVER PREVENTION: WARNINGS
The check engine light came on at 14k miles indicating there was an emissions error. The brakes squeal and have had to be replaced 3 times since the original purchase in March of 2024. After the third replacement of brakes they still squeal. Even if the car is not braking it makes the noise. The radio shuts on and off constantly. Chevy reported they are aware of the issue but there is no fix at this time. The dealerships reset the radio but the issue persists. I’ve had to park the car because I’m afraid the brake issue is much more than they’re willing to admit.

ENGINE, ELECTRICAL SYSTEM
Had the transmission replaced after 100,000 miles. Not even a year later the whole engine blew. With zero warnings lights or signs the engine gave 5 gallons of gas was in the engine along with other issues. We replace the engine and everything starts falling apart. Another $1,400 later it’s still throwing codes which come to find out the computer is now bad. Less the 300 miles have been put on the engine since it was replaced. Constant cam shaft sensors are going off causing the car to not run. $10,000 was put into it to have a running car and huge mechanical issues continue to happen with maybe 150,000 miles. Maintenance was done regularly. Zero issues prior to the transmission which thankfully was covered under warranty.

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.

My two children and I were traveling to another state and had been driving about 2 hours when the engine in my 2022 Suburban suddenly quit working while I was in the middle of a highway. I had just accelerated and merged onto a multi-lane highway moving all the way to the far left lane when my engine completely went quiet and seemed to quit working. The car all of a sudden shifted into Neutral and started losing speed. I had to put my hazard lights on and cross back across the lanes to get back over to the emergency lane on the right all while losing speed. We were all pretty scared because the Suburban just seemed to quit working and wasn't responding. I'm thankful we were able to get safely to the emergency lane before the car completely stopped. Once I was in the emergency lane, I tried to see if the car would go back into Drive position but it would not. I turned the car off and waited about a minute and tried to power it back on but the only thing that worked was the electrical stuff in the car (the screen for my dashboard and car play/nav system) and the engine remained quiet. Once the tow truck arrived an hour later, the worker tried to jump the engine but it did not respond. It was obviously scary and has been a huge inconvenience but it also left us in a very unfortunate situation because we were in a different state and did not know the area or anyone nearby that could come and pick us up once the tow truck arrived. I was pretty much stranded with my 2 daughters and all of our luggage in a different state on the side of the road.

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.

ENGINE, POWER TRAIN
The “add engine oil” light kept coming on and I initially thought it was because they forgot to reset it after my oil change because my car wasn’t reading it was due for one. I came to find out that my car is likely burning excess oil, according to the dealership, since all of the oil was gone. GM says that it’s normal to burn oil and as long as it’s up to 2 quarts between oil changes it’s fine. The dealership recommended that I get oil consumption test and sometimes it burned more oil than normal and other times it did not. We had to go every 1,000 miles which was an issue because it’s our main vehicle for family transportation and sometimes I would have to go under 1,000 miles because we needed it for a longer trip and would be over if waited until we got back. Also, my engine fan was making a very loud noise that would run for a while after my car was turned off and I was told multiple times it was fine until one time they checked it and it was indeed an engine malfunction and my engine would overheat when I went above a certain speed. The first fix wasn’t right and had to go back. I wasn’t burning enough oil to warrant GM to do anything.

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.
