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.

ENGINE, UNKNOWN OR OTHER
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 .

My vehicle is having an oil consumption problem. 2 quarts were missing from my oils consumption test. The dealer is now doing a secondary oil consumption test and I’ve read up and learned that there have been a lot of recalls with the engine and oils changes.

Other/I am not sure
I am reporting a safety issue involving a Cybex Eternis S child car seat. The seat was manufactured on 02/28/2020 and has a printed expiration date of 02/25/2030, indicating a 10 year usable life. At approximately five years of use, the head impact foam failed and is broken into two separate pieces. The foam pieces are detached. This foam is a required safety component. Cybex customer service confirmed in writing that if the head impact foam is detached or broken into separate pieces, the seat does not meet safety requirements and should not be used. Cybex also confirmed that no replacement part is available and no repair or remedy is offered. As a result, the seat is unsafe and unusable halfway through its stated usable life, with no ability to repair or replace the failed safety component. This raises concerns about product safety support for child restraint systems marketed with extended usable lifespans.

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.

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.

We have 8,625 miles on our 2025 Suburban. We were going down the highway when began to hear a unfamiliar noise. We pulled over into an error to inspect and didn't notice anything under the vehicle, which we thought might have cause the noise. We put into drive and went less than an 1/8 of a mile and our suburban lost acceleration and stopped. It would not start and couldn't not be moved, until roadside assistance took it to a Chevrolet dealership. The dealer stated the engine seized up and needs to be replaced. We were fortunate we were not going any more than 20 miles per hour and were not on a major highway.

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.
