ENGINE, POWER TRAIN
This 2025 Chevrolet Tahoe has experienced three separate and recurring engine-related failures. The first failure occurred at approximately 41,350 miles and required replacement or repair of the lifters and camshaft. The vehicle remained at the dealership for approximately 15 days. The second failure occurred at approximately 54,619 miles and involved another lifter failure along with traction control problems. The third failure occurred at approximately 65,140 miles. The Check Engine warning light illuminated while the vehicle was being driven, and the vehicle again experienced engine-related problems. The vehicle has now been at the dealership for more than one week, and no repair or permanent solution has been provided. I am concerned that these repeated engine failures and traction control problems create a serious safety risk, particularly because the vehicle is driven on public roads and highways. Despite previous repairs, the engine problems continue to recur. I am requesting that NHTSA investigate these repeated safety-related failures.

ENGINE, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I was on the interstate. Initially I heard a faint rattling sound. I turned off the radio and AC to listen more closely; the sound was not audible. But then traffic came to a standstill. As I slowed, that barely audible noise began to sound like something boiling in the engine. The temperature and pressure gages were all in normal operating ranges. I pulled to the shoulder of the interstate and checked under the hood. I noticed a distinctive squeaking sound although the fan belt was intacted in running true. There was no sign of any fluid loss in the engine compartment or underneath the vehicle. While attempting to get to a Chevrolet Dealership one exit away, the vehicle stopped running while at a stop light. additionally, there is a recall on this vehicle for the automatic braking system. GM and the dealerships are aware of this recall yet this website states there are no recalls.

ENGINE
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.

ENGINE, FUEL/PROPULSION SYSTEM
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.

ENGINE
I purchased a new 2026 Chevrolet Tahoe approximately five months ago, and it currently has only 11,300 miles. Unfortunately, while driving on the highway last night, the 6.2L engine suffered a catastrophic failure. Seconds before the failure, the check engine light illuminated, and the vehicle immediately lost power while traveling at highway speed, creating a significant safety concern for both my family and other motorists. The vehicle is currently available for inspection. I am waiting for General Motors to advise which dealership the Tahoe should be towed to for diagnosis and repair. While I understand the vehicle is covered under the factory warranty, experiencing a catastrophic engine failure on a five-month-old vehicle with only 11,300 miles has significantly diminished my confidence in it. I purchased this Tahoe expecting years of dependable service, not a major engine replacement within the first few months of ownership.

AIR BAGS
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

POWER TRAIN
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.

ELECTRICAL SYSTEM, SEATS
ON JUNE 2ND 2026, the air conditioning in my 2025 Chevrolet Tahoe failed without warning. The system began blowing warm air instead of cold air, making the vehicle uncomfortable to drive. At the same time, I noticed that both front ventilated (cooled) seats had also stopped working. Although the seat cooling indicator lights illuminated when activated, the seats did not produce any cooling. I called to schedule an appt and took the vehicle to the dealership for diagnosis and repair on june 4, 2026. The dealership determined that the A/C condenser had failed and replaced it. I was advised that the repair had been completed, and I picked up the vehicle believing the issue had been resolved. Shortly after the repair, it became apparent that the problems had not been fully corrected. While the air conditioning initially appeared to function, the ventilated seats continued to provide no cooling despite appearing to operate normally. This marked the beginning of an ongoing series of HVAC-related failures that ultimately required multiple return visits to the dealership.

ELECTRICAL SYSTEM, ENGINE
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.

ENGINE
While driving, my Chevrolet Tahoe suddenly developed a severe, rhythmic bottom-end engine knock, indicating a catastrophic internal mechanical failure. I immediately took the vehicle to an authorized Chevrolet dealership on May 29, 2026, for emergency diagnosis.The dealership technicians officially diagnosed the issue as a severe lower-end engine failure. They deemed the engine unrepairable and determined that a complete long-block engine replacement is required.As of today, July 6, 2026, the vehicle has been sitting at the dealership for over 5 weeks and has yet to be fixed. The prolonged delay and sudden mechanical failure present a severe safety hazard, leaving me without a vehicle due to known GM manufacturing defects currently under NHTSA investigation. This report is being filed to document the failure of the 6.2L engine lower end, the necessity of a full long-block replacement, and the ongoing repair delay.

FUEL/PROPULSION SYSTEM
Tahoe failed mid driving in a public roadway, computer system said press to restart and car made a whirling noise. I was unable to restart or put into neutral to move. This was a safety concern due to it happening mid driving, and I had my two young children with me.

POWER TRAIN, ENGINE, FUEL/PROPULSION SYSTEM
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.

ENGINE
After driving the vehicle for 5000 miles, the check engine light appeared. We brought the vehicle to dealership and were told that a cylinder was mistimed. They replaced a bank of lifters and returned the vehicle to us. A few weeks later, the check engine light reappeared and we noticed the engine was making some odd sounds. It wa brought back to the dealership and they replaced the fuel pump and hose. The vehicle was returned to us but the check engine light reappeared. The dealership stated that they couldn’t reproduce the problem after testing. The vehicle was returned to us but we noticed that it would periodically lose power upon driving and would have lurching sensation while driving. The check engine light came on intermittently and it is now being brought back to them for the fourth time.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Driving in bumper to bumper traffic in my 2025 Tahoe and the automatic braking system slammed on the brakes at 10 mph causing me to get rear ended.The light turned green and traffic started moving forward and I'm hitting the gas pedal when my truck just slams on the brakes causing the girl behind to rear end me. The car in front of me was moving forward and never hit their brakes but my car still slammed on the brakes for no reason. I was probably 6 or 7 feet away from the car in front. This isn't the first time this car has slammed on the brakes for no reason. It always seems to happen in the summer during sunny mornings as I'm headed east driving towards the sun. I got lucky the other 6 or 7 times this has happened up until today

ENGINE
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

POWER TRAIN, FUEL/PROPULSION SYSTEM, ENGINE
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.

ENGINE, UNKNOWN OR OTHER
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.
