My [XXX] Daughter lost the ability to put the vehicle in reverse while running errands on a Saturday. We had to push the truck out of the parking spot "backwards" in neutral in order to get the vehicle in a position to put it in "drive". She had been going in and out of shopping centers (forwards and backwards) earlier when the reverse suddenly stopped. I dropped the vehicle at a nearby auto shop in a fit of desperation (maybe 1/2 mile away). They told me they thought the transmission was shot, so I picked it up and took it to Andean Chevrolet (Dealer) in Cumming, GA. While driving it to Andean on Tuesday (2/17), the transmission went into low acceleration mode where I couldn't go into upper gears and topped-out at 3,500 rpm's max for the 13+ miles (30 min) drive. Andean confirmed on Friday (2/19) that the entire transmission is shot with metal all inside of the fluid, gears being broken, and the valve body being broken. The truck is 5.5 years old with 93K mile on it and we were just shocked. The repair for GM Reman transmission was quoted at ~$9.2K and we just finalized a call directly with GM Customer Service to see if GM would offer any discounts to the Dealer on the repairs. We are still waiting on that result while the repairs are being made. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My vehicle was subject to a GM recall involving inspection of the 6.2L engine. The recall inspection was completed by an authorized GM dealership at 58,581 miles. The vehicle was cleared as passing the recall criteria and returned to me. Within fewer than 10 miles after leaving the dealership following the recall inspection, at approximately 58,590 miles, the vehicle experienced a sudden loss of propulsion while traveling at highway speed (approximately 65 mph) on a divided U.S. highway while ascending an incline. The vehicle shifted into neutral and lost engine power without warning. Steering and braking remained functional, but the vehicle lost forward motive power in the left lane of traffic. Attempts to restart the engine resulted in a loud mechanical thud, and the engine would not restart. The vehicle was towed to the dealership. The engine is now being replaced. Prior to this incident, the vehicle had previously undergone an oil consumption test related to engine concerns before the recall campaign. This failure occurred shortly after the vehicle was inspected and cleared under the recall procedure. I am reporting this due to the sudden loss of propulsion at highway speed following recall inspection and the subsequent need for complete engine replacement.

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

ENGINE, FUEL/PROPULSION SYSTEM
I own a 2022 Chevrolet Suburban RST that has experienced ongoing mechanical and safety issues over several years. I first began reporting drivability concerns to General Motors and the dealership in 2023 and continued contacting them throughout 2024 and 2025. During one dealership visit, a sales advisor rode in the vehicle with me and stated they did not observe any issues, despite my continued reports. The vehicle later suffered a loss of propulsion and required a full engine replacement. The radiator and cooling components were also replaced by a Chevrolet dealership. Due to ongoing concerns for my safety, I contacted General Motors multiple times, requested an executive buyback, and asked about Lemon Law options. GM advised that the engine had been replaced and that I needed to take ownership of the vehicle. After picking up the vehicle last Wednesday, I immediately noticed a persistent sweet coolant/radiator odor inside the cabin and outside the vehicle that continued for nearly a week. I also experienced engine hesitation/stuttering when stopped at traffic lights as the auto start/stop feature reengaged. I attempted to contact GM again regarding these concerns prior to today’s incident. Today, while driving, the vehicle displayed an engine overheating warning instructing me to turn the car off immediately. I safely pulled over and shut the vehicle down and am currently stranded roadside. Given the repeated failures, history of loss of propulsion, multiple repair attempts, denied buyback requests, persistent coolant odor, drivability issues, and now overheating shortly after engine and radiator replacement, I believe this vehicle presents an ongoing safety risk and request formal investigation.

My 2022 Chevrolet Suburban 6.2L, approximately 96,000 miles. Vehicle was taken to dealership for transmission warning message and returned as “repaired” with a software update. The following day, February 12th, while driving at highway speed on the expressway, the vehicle suddenly lost power without warning. A message appeared instructing me to press start, and the vehicle shifted into neutral and stalled. No warning lights were illuminated prior to the stall. This created a serious safety risk due to sudden loss of power at highway speed.

My vehicle was taken in to shop due to recall recommendation I received in GM app for fuel pump control module . After repair was done my engine begin ticking the same day and failed a week later . I documented the whole thing and filed a claim with GM however the dealership that did the repair are not responding to GM . The dealership is alm Chevorlet south in Jonesboro ,GA this vehicle stalled out while I was on the highway . Please help me this vehicle belongs to my limo fleet and this is detrimental to my business . After multiple attempts to get it diagnosed they kept telling me I had to wait in line for weeks out to get it checked out although the problem arose after the new part installation . Then when I brung it back with failed engine soon after they told me that I had to sign a liability release waiver for them to check out the vehicle stating that the vehicle was high mileage and not their fault . The service manager literally instructed me not to leave my vehicle when I wanted to because it would not speed up the process for it to be seen I brung it back when instructed but it was to late because the engine had already failed . They literally forced me to sign a waiver stating that they wouldn’t diagnose it if i didn’t sign the waiver . These people are committing a fraudulent scam and their are unsafe vehicles on the road that arent being treated properly due to these practices . Please contact the dealership and or GM to take this matter more seriously .

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.

The contact owns a 2024 Chevrolet Suburban. The contact stated that while driving at various speeds, there was an abnormal sound coming from the rear of the vehicle. The sound became significantly louder while driving. The contact stated that while driving at highway speeds and depressing the brake pedal, the vehicle felt like the rear wheels would lock up. The contact stated that the rear wheels locked while reversing, causing the vehicle to jerk abnormally. The vehicle was taken to the dealer, where it was diagnosed with rear axle failure. The dealer determined that the rear axle needed to be replaced. The private warranty company declined to cover the repair unless the rear axle had completely failed. The manufacturer was notified of the failure and declined to cover the repair because the vehicle was no longer under warranty. The contact had previously reported the failure to the dealer, who could not duplicate the failure while the vehicle was still covered under warranty. Additionally, the contact stated that upon engaging the air recirculation, the contact smelled fumes. The vehicle was not repaired. The failure mileage was approximately 23,000.
