SERVICE BRAKES
I was driving home after dropping my kids off at school and when I was almost home my dash lit up with the traction control light, check engine light, ABS light, red break light, service ESC message, forward collision system unavailable message and break system failure 62 MPH top speed ( was switching between 43 MPH top speed and 62 MPH top speed ), I went to slow down and I had no brakes at all. The pedal sunk to the floor with zero resistance no matter how many times I pushed it. I live on a dead end road and thank god I had already crossed the major highway before my road because it would have been an incredibly bad accident. I finally got it to switch into neutral to stop and into park where I sat with my foot on the brake in park until someone could come out to me. I called my local dealership whom had it towed to them. My vehicle is a 2021 Tahoe with 23,014 miles at the exact moment this happened. The dealership said it was the master cylinder/brake module which is not covered under the power train warranty I still have. This is a major safety issue and it seems it is not isolated due to a simple google showing reports on other forums of other newer chevy/gms in different models have this same issue with brakes going out while driving.

UNKNOWN OR OTHER
As i was driving down the road at approximately 40-45mph the sunroof spontaneously exploded. Sounded like a shotgun going off. Fortunately i had the sun shade shut but still tiny glass shards came in and fell on my child and the entire interior in the mid section of vehicle. There was no vehicle in front of me, it was night time with temps in mid 70’s no reason it should've exploded outward as if a gun shot from inside of vehicle which also implies nothing hit glass. Vehicle is at mcconnel automotive dealership where they are telling us that warranty will not cover this and we must claim on our insurance. I also called GM headquarters and they denied claim as well (case# 95312600) have spoke with several other owners on a facebook group this has happened to and GM has and is denying warranty coverage on them as well.

VISIBILITY/WIPER
On Friday May 1, 2026 while parked at my home, the rear glass lift gate burst into multiple shards. I have taken a few photos of the outside as I found it. In my surprise, I failed to photograph the glass in the interior of the vehicle. I have owned this car since new, since near the end of July of 2025. I had unloaded some groceries from the back area, raising and lowering the large metal lift gate. The glass lift gate was NOT used. As a matter of recording, I have only lifted the glass once or twice since owning the vehicle. The main metal lift gate is the unit used most often. Apparently, this is a known issue with several reports online. What I found online seems similar in that no impact or accident occurred to cause the glass to shatter. What is odd, instead of a typical safety glass experience of a "spider web" type of fracture and the glass staying intact, this was "exploded" with the glass found in multiple shards both in the car and outside on the ground. When I called my local Chevrolet dealer, they denied knowledge of this as a problem within the fleet. Because this is a use issue and weather issue, I am having to personally pay for repair. The new window will cost almost $1000.00 to repair.

ENGINE, UNKNOWN OR OTHER, FUEL/PROPULSION SYSTEM
Check engine light illuminated on my 2021 Chevrolet Tahoe. Upon diagnostic scan, the following emissions-related fault codes were present: P11D5 (NOx sensor), P14D9 (NOx sensor), P2383 (EGR pressure sensor), and P2C7A (NOx catalytic converter efficiency). All components are available for inspection upon request. The vehicle was taken to an authorized Chevrolet dealership for diagnosis. The dealer acknowledged the emissions codes but stated that unrelated components would need to be repaired at owner expense before the emissions system would be addressed, despite these codes falling within the federally mandated 8-year/80,000-mile emissions warranty. The fault codes were confirmed by the dealership. No safety incident has occurred to date, however degraded NOx and EGR function can result in increased harmful emissions output and potential engine performance issues. Warning lamps appeared without prior incident or symptom. The manufacturer has not offered to cover the emissions components under the federal emissions warranty without the owner first paying for additional repairs that may or may not be causally related to the emissions system failure. When the dealer was directly asked, "Are you saying the emissions system itself is functioning correctly, and something else caused these codes to appear?" — the dealer did not provide an answer. This question was asked in order to clarify whether the emissions components themselves are degraded or failed, which would confirm warranty coverage eligibility. The dealer's failure to answer this question directly is noted as part of this complaint.

ENGINE AND ENGINE COOLING
The contact owns a 2021 Chevrolet Tahoe. The contact stated that while driving 65 MPH, there was an abnormal vibration coming from the engine compartment and felt in the steering wheel. The check oil warning light illuminated. The vehicle was taken to the residence and then to the dealer, where it was determined that the vehicle was functioning properly, and there was no oil leak; however, the oil level was low even though an oil change was not yet due. The dealer added oil to the vehicle, and an oil consumption test was ordered. The manufacturer was notified of the failure and a complaint was filed. The vehicle was not repaired. The failure mileage was approximately 48,000.

POWER TRAIN, ENGINE
Engine stopped while driving 70 mph down the highway and the car shifted into neutral. Had to cost to side of the road. Took car into dealership and even though the car was certified safe drive and the engine had no issues 5 months ago, I was told the engine was now locking up. The engine failed despite using the higher viscosity oil that chevy recommended. These greedy cunts at chevy placed me and my family's lives in danger to save a buck; they knew that the engines would fail and instead of replacing the engines, they put thicker oil in the cars to hopefully get the cars past warranty.

FUEL/PROPULSION SYSTEM, ENGINE, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
The car has cut off three time while at stoplights. I can get it restarted but the dealership cannot duplicate it even though there are codes in the system. Also the automatic braking will randomly stop when it shouldn’t and it is a hard braking.

ENGINE
Urgent: Engine Failure Following Recent Service – 2021 Chevrolet Tahoe To Whom It May Concern, I am writing to formally request assistance and an investigation regarding a serious engine failure involving my 2021 Chevrolet Tahoe. In July 2025, I paid out of pocket to have the lifters and camshaft replaced on this vehicle. More recently, while traveling, the vehicle broke down and was taken to Uebelhor Chevrolet, where the valve body in the transmission was replaced. After picking the vehicle up from Uebelhor Chevrolet, the vehicle broke down again approximately one hour later while in Henderson, Kentucky. At that time, the engine began smoking, running rough, and misfiring. I checked the oil level during the incident and found it to be extremely low on the dipstick (I have photographic evidence of this condition). The vehicle had to be towed to Kate Faupel Chevrolet for further inspection. I was then informed that the engine has a dropped lifter on cylinder #8 and possible camshaft damage. Given the following factors: Recent out-of-pocket lifter and camshaft replacement (July 2025) Immediate failure shortly after leaving a Chevrolet dealership Extremely low oil level observed at the time of breakdown (with photo documentation) Diagnosis consistent with potential oil starvation and internal engine damage I am requesting that General Motors conduct a full review of this situation to determine responsibility. This raises serious concerns about a potential defect, improper prior repair, or a service-related issue that resulted in catastrophic engine damage. At this time, I am not authorizing repairs until liability is determined. I am requesting: A formal case review and investigation Assistance with repair or full engine replacement Guidance on how this situation will be resolved This incident created a significant safety concern, as the vehicle became disabled shortly after leaving a dealership during travel. Please contact me as soon as possible to discuss next steps

POWER TRAIN
Transmission has had a failure to shift problem on several occasions resulting in deceleration and a decreased ability to accelerate. This has occurred on most occasions at highway speeds while passing a vehicle causing a very unsafe condition. Dealer has evaluated and determined the transmission valve body is defective and needs replaced. Upon researching the problem, many similar GM vehicles are experiencing the same issue

FUEL/PROPULSION SYSTEM, ENGINE, ELECTRICAL SYSTEM
My 2022 Chevrolet Tahoe diesel unexpectedly lost power while driving. I was stopped, made a right turn, and accelerated to approximately 34–40 mph on a two-way street when the vehicle suddenly shook, shifted into neutral, and the engine shut off without warning. There were no warning lights, dashboard messages, or prior symptoms before the failure. I was driving with two young children secured in car seats at the time. This created a serious safety risk because the vehicle became disabled in the roadway, and I had limited control while traffic was present. The vehicle has not yet been diagnosed, and the exact failed component/system is unknown. The vehicle is available for inspection upon request. The incident has been reported to a dealer or service center, but the problem has not yet been confirmed or reproduced at this time.

After a rain fall a "swooshing" sound is heard above, water will pour through the overhead lights where the onstar is, the seatbelts and the back interior lights. The drain tubes to the sunroof have been cleared and the problem still persist. When the water comes in the buttons start blinking and it causes a risk to the person driving when they are distracted by the water pouring in and the water pooling under your feet possibly causing your foot to slip while driving.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: WARNINGS, ENGINE
I am filing a safety complaint regarding my 2025 Chevrolet Tahoe Premier for repeated brake assist/braking failures. Most recent incident: While driving, the check engine light came on. I turned the vehicle off for approximately 10 minutes and restarted it, but the check engine light remained on. Approximately 20 minutes later, multiple warnings appeared on the dash including: “Brake Assist Failure Press Hard to Brake,” “Speed Limited,” and “Service ESC.” At that point, braking ability was severely reduced. I was close to my destination and approached a stop sign. I intended to roll through the stop sign because the brakes were not functioning normally, but another vehicle suddenly approached. I pressed the brake pedal with both feet. The brakes were stiff and hard to press. The vehicle still did not stop properly and came to a stop in the middle of the road past the stop sign. After arriving at my destination, the vehicle sat for approximately 1–2 hours. When restarted, the brakes appeared normal again, but the check engine light remained on. In the MyChevrolet diagnostics app, it then showed warnings for Engine and Transmission System, Transmission System, and Four Wheel Drive System. While driving to the dealership afterward, the vehicle also began shaking. This same issue previously occurred on April 16, 2026. I was driving on the interstate when the brakes lost assist and the dash displayed “Service ESC,” “Brake Assist Failure Press Hard to Brake,” and “Speed Limited.” After reaching my destination, I was told by someone at the dealership to turn the vehicle off for 10 minutes to see if that would fix things, so I turned the vehicle off for about 10 minutes. When restarted, all warning lights were gone and braking returned to normal. I still drove the vehicle to the dealership that same day for service. This is a repeated, intermittent brake failure / brake assist failure creating a serious safety hazard and near collision risk.

ENGINE, FUEL/PROPULSION SYSTEM, POWER TRAIN
The engine randomly shut off while driving down the interstate and wouldn’t start back up. The car had the recall “remedy” done to it. Inspection and thicker oil. The only warning I got was to restart the engine after it shut off. My safety was compromised by breaking down on a main interstate coming through Memphis with no emergency lane to pull over in.
