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.)

Engine rattles and noisy, now auto light and message board states "Add Engine Oil)

The lights flash high beam, low beam, high beam, low beam, while I’m driving. Nothing seems to keep them from doing that.

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

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.

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.

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 woul

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.

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.

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
