ENGINE
I purchased a 2023 Suburban on March 6, 2026 with 52,980 miles. I drove it home to my house and parked it. On March 7, 2026 about 6pm, I started the vehicle and heard a loud engine noise. I called the dealership and let them know about the noise. On March 9, 2026 I towed it back to the dealership. The vehicle has been in service since then and was told it needs an engine. Metal spun threw the engine block and has to replaced. I just purchased this vehicle and drove it one day.

Regarding a catastrophic engine failure involving my 2023 Chevrolet Suburban equipped with the 6.2L L87 engine. There is an active GM service bulletin that we never received from either Crabtree or GM. Vehicle details: • Purchased in North Carolina in 2024 • Approximately 4,000 miles at purchase (used, still under factory warranty) • Currently at approximately 60,000 miles • Within the 5yr/60k powertrain warranty at the time of failure Incident details: On Friday 2/20, the engine experienced a confirmed catastrophic failure while my wife was driving on the interstate at highway speed. The vehicle abruptly lost power, creating a significant safety hazard. She was able to maneuver to safety, but the situation presented a serious risk of injury. GM has since towed the vehicle and confirmed catastrophic engine failure. We have been provided a rental vehicle - not a comparable one either (they refuse to address that also). Given the safety exposure and warranty status, I am evaluating potential potential claims including breach of warranty, implied warranty of merchantability, and any product liability considerations. I am also interested in understanding leverage for buyback, diminished value, risk of serious injury to my wife, or extended warranty resolution. I have preserved documentation, service records, and a written account of the incident.

SEAT BELTS
The drivers side, female end, of the seatbelt comes undone when cold. This is reproduced every single time it is cold for approximately 5 minutes of driving until the inside of the vehicle warms up. This happens with both primary divers of the vehicle. We took it to the dealership we bought it from but because there is not a current recall and they cannot reproduce the issue since our current temperature is in the 40s, they won’t replace it under warranty. No warning systems go on when this happens while driving.

VISIBILITY/WIPER, UNKNOWN OR OTHER
Sun Roof has leaked. The Sun roof leaked a considerable amount of water and it came through the head liner around the ceiling mounted control panel as well as the back of the car. This is the second time it has happened and I have been told it is not covered under warranty. Through online blogs and forums I have found that this is a common issue with 2021 and newer tahoes and suburbans. And that is a reoccurring problem that is commonly not fixed properly by the dealers This causes a safety and health issue as well as an unacceptable vehicle defect. 1.) From a safety standpoint, if I am driving down the highway and a large amount of water starts pouring out of the headliner on the driver it causes a major distraction that could lead to high speed accident. 2.) From a health issue, regular water leaks could lead to vehicle mold and water damage. I have children, if they become susceptible to the mold it could cause health issues for me or my children. 3.) The water that pours out of the ceiling lands on the dash electronics which could lead to more vehicle issues by damaging electronic controls. It is my opinion that this is a major vehicle defect and something should be done by the manufacturer to correct it. I have made a complaint to the Chevy Customer service under reference #890 780 85

Following extensive research & uncovering the fact that there are several class action lawsuits underway calling out GM for not issuing a formal recall when they should have from the start, we've been forced to personally absorb significant costs tied to replacing our 2023 Suburban's Valve Body around the mid-December FY'25 timeframe. It's also been publicly stated that GM opted to "not release" an official recall for the 1500 series Suburban when they've already issued an official recall for the larger 2500 series equivalent, according to our local dealership. We've already filed an official "full credit request" with GM's complaints organization, but we're sensing our voice will likely remain unaddressed at this point unless proven otherwise. Additionally, this is the second purchased Suburban with a YukonXL, being our original purchase from many years back, but in short, we're going to transition away from GM vehicles long-term, assuming our "full credit request" remains ignored. In short & our local dealership totally agrees with our current stance, critical transmission components should not be failing at this point & especially with a newer Fy'23 Suburban, when behind the scenes GM opts to "not recall" saving the company north of 600M from many months back. Just terrible from so many perspectives, as disgruntled end-clients like myself suffer from forced irresponsible cost requirements.

ENGINE, POWER TRAIN
My 2023 Chevy Suburban High Country had the L87 Engine Loss of Propulsion (Related field action: See Special Coverage N252494003) recall performed on it and completed on August 15, 2025. Higher viscosity oil was put in. This was at approximately 55,000 miles. While driving on the highway at 60mph on December 29, 2025 the vehicle twice lost propulsion and indicated the vehicle needed to be restarted. I took it to a Chevy dealer to have looked at in early January 2026 and they could find no issues or codes. On January 31, 2026 while driving on the hwy at 75 miles per hour the vehicle started to rattle and it lost propulsion. The DIC indicatd "System Failure" and I had to pull off to the shoulder of the highway. The DIC repeated "System Failure" and that the vehicle needed to be restarted. The vehicle would not restart when attempting to press the brake and restart. This happened on a busy interstate and the safety and well being of my family inside was put at a risk that could have been avoided, likely if the engine would have been replaced in August of 2025. The temperature outside was in the single digits and there was no air pushing through the vehicle while we waited for a tow truck and another family member to pick us up off the highway. There was no warning lights or messages prior to this happening. The vehicle is currenlty undergoing diagnostic testing at a Chevy dealership. This happened at 69,000 miles. This is highly concerning that this could happen in a 95,000 dollar vehicle. This is absolutely a saftey risk. I'm lucky I was able to merge on the interstate in a vehicle that could not maintain the speed with traffic and pull off to the shoulder.

The code that originally came up was P0300 a (Engine Misfire). I had this truck for one year and it says my fuel injector went bad so I’m getting the whole Tune Up done. I have the My Chevrolet app connected to my vehicle and it’s saying: the Engine/Transmission system needs service and the Emissions system! Mind you I e only had this vehicle for one year i bought it in February 2024 and it’s a 2023! I bought it from Lindsay Ford in Wheaton MD. I feel as though all this should not be happening in a matter of one year l believe I was sold a defective truck.

OEM Running boards, non powered. It is available for inspection. The running boards are slippery evetime they are wet. Does not matter what shoes you have. I have slipped 4 times since owned the vehicle and even broke the interior panel of my driver side door in 2023 which lead to a$500 repair bill. My wife and I both slipped today (1/26/26) and bruised pretty bad. Kids have also slipped in the past. No, it was not inspected or reproduced but dealer did say its a common problem they see with the OEM running boards. No, it was not inspected by the dealer. No warning lamps since it is a non powered part.

After just getting our vehicle back on 12/11/25 from our incident on 11/9/25 when my wife was driving at 70 MPH on the highway when the engine blew the first time. Approximately 1300 miles later and 15 days after we picked up the vehicle when I was merging onto the highway the vehicle had a sudden power loss and a smell that filled the cabin. We were able to drive to the next exit and while the vehicle was idling it sounded awful. The check engine light started to flash along with the TCS light and the collision warning lights. After getting to a parking lot when called OnStar to tow our vehicle to the closest dealer. I have not received any updates yet but it is very similar to what happened the first time when the engine needed replaced.

SERVICE BRAKES
I was driving to work last Wednesday, and I live on a hill. As I was driving, a "Brake failure" alert came over my dash and I lost all control of my brakes!!! I live right off of Main Street, and my options were only to go straight and into a house, or to turn onto Main Street and hope no one hits me or that I don't hit another vehicle. I turned and thankfully no one was coming. At the end of that street I was able to coast into an closed down gas station and park the vehicle. I called the dealership I had purchased this vehicle from 10 months prior, and they told me I had to use OnStar to have it towed to them. I did that, and they towed it to the dealership. The next day the dealership told me the cause of losing my brakes was due to a SOFTWARE UPDATE that was needed!!!!! They charged me $800 for the update & a battery that they said was not holding the charge, which I've never had an issue with. I had purchased an extended warranty with this vehicle and I was told it would be a bumper to bumper warranty AS IF I had purchased it new (it was 2 years old). The dealership said this was not a critical software update and was not covered under any warranty. I could have been KILLED or seriously injured or killed or hurt someone else due to my brakes going out due to a SOFTWARE UPDATE that was needed!! This is insane!

SEAT BELTS
The vehicle was purchased brand new from the manufacturer. Because the third-row seating was rarely used, it was not immediately apparent that the car was delivered without one of the required seatbelts. Once the issue was discovered, it was promptly reported to the manufacturer. However, the customer service representative refused to address the problem, stating that the warranty period had expired. This is a serious safety hazard. A missing seatbelt poses a significant risk of severe injury or death in the event of an accident, and it requires immediate corrective action.

ELECTRICAL SYSTEM
Since purchasing the car in March 2023, the battery has died 5-7 times. We contacted our dealer and they claimed nothing wrong and the battery was fine. We have contacted them about this issue and there is no fix. They performed an update in June 2025 which was supposed to fix it but it didn’t. The latest it has died is November 25. There was nothing left on for the battery to die. I have 4 children and it’s starting to get very cold outside. I live in a rural area with poor cell reception. I am worried I’ll be stranded somewhere with a new baby and 3 younger children.

SEAT BELTS
While driving a 2023 Chevrolet Suburban (VIN: [XXX] ), my [XXX] son was seated in the second-row center seat and was properly buckled in with the factory shoulder/lap belt. He turned around briefly to grab something from the back of the vehicle, and during that movement the seatbelt fully extended and then locked in the automatic locking mode. The retractor would not release tension afterward. The belt continued tightening around his torso, and no amount of slack could be pulled back out. The belt became so tight that he was unable to breathe comfortably or free himself, and the locking mechanism would not disengage even after the vehicle was stopped and turned off. The seatbelt remained fully cinched and would not retract or loosen under any circumstances. Because the belt created a serious entrapment hazard and my child could not safely be removed, I was forced to cut the seatbelt to free him. This appears to be a dangerous malfunction of the seatbelt retractor/locking system and presents a significant safety risk, especially for children who may shift or turn in their seats during normal use.

My 2023 Chevrolet Suburban High Country (VIN: [XXX] ) suffered a sudden and dangerous engine failure while my wife was driving 70 mph on the interstate returning from our child’s sled hockey tournament in Ohio. The vehicle gave no warning lights, alerts, or diagnostic messages before the failure. While driving in the right lane, the vehicle began losing power and making a loud noise. My wife exited the highway and contacted OnStar, who told her the tow would take over an hour and only cover three miles to closest dealer, leaving her stranded in an unsafe area. She attempted to carefully reach a nearby dealership. During this attempt, the vehicle completely shut off and she lost all engine power. The vehicle lost all power making the final turn into the dealership coming to rest in the middle of oncoming traffic of a four lane road. The Suburban would not restart. A tow truck arrived and transported the vehicle to a dealership. When they arrived, the tow driver noticed smoke and a strong burning odor coming from the engine compartment and told her to move away from the vehicle because it could potentially catch fire. The vehicle was left in the lot with the hood open and positioned away from the building for safety. The dealership has determined the engine suffered a catastrophic failure and requires complete replacement. Multiple related components may also be affected. This occurred on a vehicle with only 54,000 miles that was purchased three months earlier. This incident created a serious safety risk for my wife, who was nearly stranded on an interstate and had to maneuver a powerless vehicle across several lanes of traffic. I am reporting this to NHTSA due to the sudden failure at highway speed, lack of warning, and potential fire hazard.
