POWER TRAIN07/21/2026
While traveling out of town on the highway,we had a sudden loss of power. My vehicle wouldn’t accelerate or shift. My check engine light came on and a message displayed that said something about reduced power. After limping to a dealership while in another city, I managed to wait hours for my husband to pick me and my children up. We waited several days for the dealership to tell us it was the valve body that needed replaced. My vehicle was NOT in the original recall for the valve body, although we experienced the exact same issues that the recalled vehicles experienced. This entire experience was horrifying. Along a stretch of highway that I was unfamiliar with, speed limits of 80mph, and a sudden, complete loss of motor power and speed, this could have someone. I had a vibration while staying at any constant speed for months prior to this, I had taken the vehicle in numerous times but was told the only thing to fix it was a software repair and that wouldn’t take care of the problem entirely. This vibration was and still is so bad that my phone will fall from the magnetic mount if I don’t let off the accelerator or increase acceleration. My vehicle still doesn’t seem to run properly but I am unable to get it to reproduce any issues when at the dealership. Extremely unnerving to travel with my family out of town or state and wonder if my fairly new vehicle will make it.

Rear wheels suddenly lock up momentarily during downshift at 30-50 mph (most reproducible 35-40). Transmission in a high gear (8th-10th); any throttle input commanding a downshift can trigger it: as the downshift executes, rear wheels briefly stop, skid with an audible chirp, vehicle jerks violently. Reproducible on demand, multiple times per drive, on video. Highest-speed event ~50 mph, family aboard. NO advance warning: no check engine light, no message, no stored code, no gradual onset. Traction control sometimes activates at the instant of the skid, sometimes not — always reacting to traction already lost, never before. A driver has no opportunity to anticipate or react. THIS IS A LOSS-OF-CONTROL HAZARD. It is especially dangerous in a turn, on wet pavement, or in traffic. Onset May 2026. Pursued repair since, across three shops: an independent, twice (no codes/leaks/abnormal findings; MAF replaced; unresolved; referred to dealer), then a GM dealer 3 days (test drove 34+ miles, no codes, fluid good, all shifts correct; declined recommended control-module recalibration, cause unconfirmed). Lockup recurred within 5 miles of leaving, same day; I returned immediately, asked for a tech ride-along while fresh — did not occur. Next day, a second GM dealer: tech note said fluid was low, though the same RO's inspection passed that fluid and found no leak; no leak ever identified anywhere. Paid $672 for a fluid exchange — unresolved. Days later, same dealer measured 265F on a 30-mile road test and condemned the transmission. Full replacement underway, largely out of pocket. Symptom matches recall 26V-085 (momentary rear wheel lockup, worn control valve, 10-speed/ETRS) covering 2022 models. My 2023 is not included. I am not asserting a diagnosis — no one has established the cause — but I ask ODI to consider whether that campaign should include additional model years. The failed transmission is available for inspection; videos available on request.

Piston ring went bad causing catastrophic engine failure. Now needs new motor. Only had 62k miles. It had been burning oil but was taken to the dealership for maintenance and they didn’t report anything.

I was a victim to the L87 Engine Loss of Propulsion recall. On June 19, 2025, my engine was replaced as it failed all test. After getting a new engine, I have had 5 engine misfires and the dealership blamed it on faulty gas. Now my 2023 Chevrolet Tahoe that I trust to drive my two toddlers around, is at the dealership for a flashing engine light. Even after the engine was initially “remedied”, the new engine continues to fail and I have lost trust in having a safe and reliable vehicle.

We purchase the vehicle in February of 26’. Certified preowned they a Chevrolet dealership. It was disclosed to us that the engine had been recalled and replaced in September of 25’ (had about 1500 miles put on it, before we bought it) due to the ongoing issues that plague the V8 6.2L motors. We put less than 3000 miles on the vehicle and wanted to take it in for oil change and new tires. My wife had heard a rattling/ticking sound and wanted the dealership’s service department to check it out. They test drove the vehicle and immediately told us that this second engine needed to be replaced with less than 4,500 miles on it. We’ve now had a loaner for almost 7 weeks while we wait for a new 6.2 liter engine that no one is even sure won’t have the same thing happen to it that the first two engines had happen. GM needs to correct this issue. I read that over 1100 6.2 liter engines are on back order. This is unacceptable.
ELECTRICAL SYSTEM,ENGINE07/06/2026
We had car checked due to strange and erratic shifting in less than a year of owning. Then took in for recall, they stated it was fine and performed the remedy with higher grade oil. Still had issues and took to another dealership to look at and they stated it was fine as well. About 2 months later while I was driving it was hesitating and would kind of buck and when I was about to turn on to a busy road it just stopped. I couldn’t do anything at all, the entire car was locked up. The tow truck driver couldn’t even get it into neutral to tow. Dealership said it’s the engine and it needs to be completely replaced.
UNKNOWN OR OTHER,ENGINE06/29/2026
Space does not allow for a complete statement. However, here is a summary. I purchased my 2023 Tahoe on 07/19/23. On 07/27/23, the check engine light came on. Since then, there have been approximately 8-9 instances where the check on. Each time I took the vehicle in for service, however, the check engine light kept coming back on. There have been 2 instances in 2026 where the vehicle would not start, and then the check engine light came on. A Chevrolet dealer service advisor told me that this is a known issue with GM and Chevrolet; however, no remedy has been found yet.
VISIBILITY/WIPER06/16/2026
Following a GM-initiated over-the-air (OTA) software update on May 18, 2026, my vehicle's windshield wipers became permanently inoperable — stuck in the "on" position with no ability to turn them off. This is not a gradual mechanical failure or wear-and-tear issue. The malfunction began immediately and directly as a result of a software update pushed by General Motors. Because the wipers cannot be controlled, I have been forced to remove the wiper fuse to make the vehicle driveable. This means I am currently operating a vehicle without functional windshield wipers — a federally mandated safety system. I want to be clear: this unsafe condition was caused entirely by a GM software update, not by any action or negligence on my part.

The contact was able to pull over safely. The contact stated that the failure was recurrent. The dealer was notified of the failure and diagnosed the vehicle with a valve failure. No further information was available. The manufacturer was notified of the failure. The failure mileage was approximately 57,000.

Total engine failure.
ENGINE05/26/2026
While traveling at 55mph yesterday, I experienced a full engine failure which shut the car off fully while traveling on a single lane double yellow road. I was able to coast to a secure location. The car will not start or go into neutral. There were no warning lights that occurred at any time prior to the failure. This all occurred while on vacation 2 hours away. I previously went to the dealership for the recommended "fix" for the recall but that obviously did not solve the problem. This was an extremely unsafe situation for me and my family. I also encountered towing costs and significant loss of time. In addition, the car is at a dealership over 2 hours from my home. Chevrolet should be held accountable well beyond a recall notice which didnt solve the problem.
