I was having an airbag light randomly come up on my dash, and when I would start the vehicle it would state “Service Restraints system”, this started this summer when the weather got hot outside. I took the vehicle in to Serpentini Chevy is Tallmadge Ohio 44278, and they said that a wiring harness and connector need replaced. I saw that there was a recall in 2021 for this exact issue. My vehicle is 5 years old and under 100,000 miles and has never been in an accident and was Chevy certified pre owned. Due to this being a airbag safety issue and a previous recall, it should be a current issue and recall as well

My transmission failed and it has been in a shop for 2 months. The pistons in the transmission failed not sure why but made it not go in reverse. The parts were on backorder for atleast a month. The warranty is out and my extended warranty will not pay because Chevorlet Dealership failed to flush my transmission when it was in for service. The transmission is a known problem on these models and was recalled for the diesel models but not the gas models.

DATE: 06/17/2026 The engine shuts off without warning while I am driving, recurring roughly every 10 miles. When it stalls, the dashboard and electrical accessories stay on, but the vehicle loses motive power, along with power steering assist and power brake assist, which is extremely dangerous at road speed and in traffic. This began immediately after dealer service completed on 6/18/2026. During that visit the dealer performed two safety recalls (N252494000, the "L87 Engine Loss of Propulsion" PicoScope inspection with oil change; and N252510321, ECM software reprogramming) and a valve lifter replacement that required removing both cylinder heads. The vehicle was running and fully drivable when I dropped it off, and was returned stalling repeatedly while driving. It never did this before the service. At first the engine would not restart after stalling. The dealer replaced the starter; it now restarts but continues to stall every ~10 miles. A dealer diagnostic scan recorded numerous "Lost Communication" codes across nearly all control modules, plus control-module input-power codes showing low voltage and power-circuit correlation faults (e.g., U3505, U3018, U3007) and an active loss-of-communication code for the power steering module — consistent with an intermittent loss of electrical power or ground affecting engine control. The engine passed the recall's connecting-rod/crankshaft (PicoScope) inspection, so this is not the recalled bearing failure mode. The vehicle is currently at the dealership and is undrivable. The dealer has ordered a new engine and apparently also a new radiator for reasons unknown. No crash or injury has occurred to date, but the vehicle lost power while on the freeway at speed multiple times. A GM customer assistance case is open. Repair orders and the diagnostic scan are available on request.

The engine's Dynamic Fuel Management (DFM) lifter failed and damaged the camshaft at around 70,700 miles. The broken components are available for inspection upon request. This failure put occupants at risk because the vehicle suddenly lost power, began shaking violently, and could not accelerate safely in traffic. This unexpected loss of propulsion created an immediate collision hazard. The problem was officially diagnosed and confirmed by a repair service center. It has not been inspected by police or insurance representatives. There were no advance warning signs. At the exact moment of the failure, the check engine light started flashing, the car began shaking heavily, and the engine made a loud knocking sound.

After a car wash, the car started to smoke out of a tail pipe, down shifting hard, car was shaking while running in park in the driveway- so we took it right to Chevy Turnersville, and they are now saying the whole engine is internally damaged ( not by the carwash) and the whole engine needs to be replaced. The trucks warranty just expired in Feb, the car ran perfectly fine before this. I dont understand how an engine just stops working this fast and out of no where. We took very good care of this truck. Oil changes every time we needed, new tires, new alignment, the mile recommendations, everything! and this happens out of no where. It will now cost $12,000 to repair this which we do not have. Please help and explain this

While driving my 2021 Chevrolet Tahoe, the check engine light illuminated. Shortly thereafter, the engine began shaking severely and I heard clicking and popping noises from the engine compartment. The following morning, the vehicle was barely operable, shaking excessively and unable to properly reverse. Due to the unsafe condition, I had the vehicle towed to the dealership. The dealership diagnosed a failure involving all 8 lifters on one side (bank) of the engine, requiring extensive engine repairs. My vehicle has approximately 74,000 miles, which I believe is low mileage for such a significant internal engine failure. The symptoms included severe engine vibration, misfiring, loss of performance, and the potential for loss of power while driving. This is not the first major failure I have experienced with this vehicle. In approximately April 2023, when the vehicle had about 32,000 miles, it unexpectedly shut off while I was reversing in a roadway. The dealership diagnosed a failed fuel pump control module (fuel pump modulator). Similar failures were later identified in recalls and corrective actions affecting other GM vehicles. I am concerned that my vehicle has experienced multiple failures involving components that appear to be associated with known issues affecting GM vehicles, yet my Tahoe was not included in applicable recalls. These failures created significant safety concerns, including unexpected engine shutdown, loss of vehicle operation, and potential loss of power while driving. I respectfully request that NHTSA investigate whether my 2021 Chevrolet Tahoe vehicles should have been included in existing and future safety recalls related to these defects and other known defects that GM vehicles are experiencing with the motor, transmission and other parts. Note: No invoice is available yet as I am seeking GM assistance due to no warranty status. Estimated repair cost from dealership is up to $8,900.

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.

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.

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

The component at issue is the engine, which suffered a sudden and catastrophic failure due to unknown causes. At no time prior to this incident were there any warnings, symptoms, or indications of an underlying mechanical defect that would have allowed for preventative action. While operating the vehicle on the highway with my family present, multiple warning indicators activated simultaneously, including a blinking check engine light, traction control light, ESC warning, and a forward collision warning. Immediately thereafter, the vehicle experienced a rapid and significant loss of power accompanied by a loud and persistent engine knocking noise, rendering the vehicle unsafe to operate and placing the occupants at risk. It is important to emphasize that traction control and ESC systems are not causally related to an engine misfire condition, further supporting that this event was abrupt and not part of a progressive or diagnosable issue. A diagnostic scan performed at that time identified a misfire in cylinder 1. Upon delivery of the vehicle to the dealership for inspection, it was determined that the engine had suffered complete internal failure and was deemed “blown.” This finding confirms the occurrence of a catastrophic mechanical breakdown. Based on the sudden onset, absence of prior warning, and severity of the failure, there is no reasonable basis to attribute this condition to normal wear and tear, operator misuse, or neglect. Rather, the facts support the conclusion that this was the result of a latent defect or internal mechanical failure beyond the operator’s control. Accordingly, this matter should be addressed under applicable warranty coverage or consumer protection standards.

Since March of 2025 I have identified a critical safety defect with my vehicle. When driving and without warning, the vehicle unexpectedly shifts to neutral, experiences a loss of propulsion, and the engine shuts off. This has occurred multiple times in which I narrowly escaped collisions with other vehicles or objects. If this would occur at a high rate of speed, it would certainly result in serious accident including possible fatality. I have experienced three near-accident scenarios when I had children in the vehicle. I have worked with Classic Chevrolet in Sugar Land, Texas who has made six attempts at repair. They have each time found a different component attribute to an error code and replaced that part. After each visit they tell me that the car is fixed and safe to drive. They have never been able to provide a clear explanation as to why I am experience this reoccurring issue, but attribute it to a different part each time. Within 5 days to 2 months, the incident repeats. I have recent video of the incident that I can share.

Driving down the highway and I lost all the gears it went from driving speed then wouldn’t go over 30 mph. When I got pulled into a business on the side of the road then tried to restart it it then wouldn’t go into reverse. It was dangerous because there was cars behind me going the speed limit then my car just lost speed. No warnings it’s not throwing any codes. Looking on the internet it seems it’s the transmission or valve body

I was driving yesterday and noticed my transmission started to shift hard and unnecessarily. Then I received a warning that propulsion was affected and to drive with care. The check engine light came on. I was able to make it home, but the vehicle wouldn't go into reverse. I had it towed to a dealership today and they identified the issue as being related to the valve body. Apparently a recall was just issued for this on the 2022 Chevy Tahoes. I'm not sure why this isn't being extended to the 2021 model.
