2025 Chevrolet Tahoe

On March 21, 2026, I rented a Chevrolet Tahoe (approx. 24,450 mileage driven). While operating the vehicle on a freeway at approximately 40–50 mph, the braking system and ABS failed suddenly without any warning. Barely no brakes were able to apply to stop the vehicle. It also started to show that ECS service (Electronic Stability Control) and Service Brake Pad Monitor. Many faults started to show.

I have a 2025 Chevy Tahoe and the automatic braking system is way too sensitive. When I’m reversing, it constantly slams on the brakes even when I still have enough space and nothing is in my way. It also brakes when people are nearby but not actually in my path. One time I was stopped and about to move forward, and the car suddenly braked because a construction worker was a few feet away, not in front of me. It caught me off guard and didn’t feel safe. The braking is very sudden and aggressive, and it makes normal driving and parking difficult. It feels unreliable and could cause a dangerous situation.

Pulled into a pharmacy, vehicle died and completely shut off while driving. 3400 miles, towed to dealership, March 5, 2026. Still no answer from dealership for why this happened and no loaner vehicle yet because they cannot confirm it's a warranty issue

I backed out of my driveway put it in drive stepped on the gas and the car hesitated and just shut down. Steering wheel locked up I had no time to even stair it out of the road. Try to start it and would not start but the dash and radio would come on. Tried to get in neutral to get it out of the road but everything is electronic so we could not do it. We had to have the car towed to the closet dealership. It took them two weeks to even diagnose the problem working along side GM service. Two weeks could have been saved with GM knowing they had a bulleting and problem with the LZO 3.0 Duramax diesel motors. It is not week 5 I still do not have a car and they have not even started putting the new motor in. GM has not been helpful AT ALL! It has been a miserable 5 weeks. They told me I could rent a car myself with a cap of $44 per day with all taxes and fees included and I MAY be reimbursed. So I have to put the money out of my pocket first and they may reimburse me. At this point I would be already out $1540.00 which is not in my budget. I purchased a brank new 2025 Chevy Tahoe 3.0 Duramax diesel motor car and it only has 8k miles on it and the motor is blown. I also paid for the car in full. I have asked GM numerous times to tell me where I went wrong and they have no answers as usual. It has been a horrible experience to this point and I have no idea when it is going to end. The dealership is trying to tell me that my car would not have dies going at higher speeds. I am so luck it happened in my neighborhood and not while on the highway. I could have been killed!

I was driving when I noticed my vehicle lagging and possibly misfiring, and then the "Service Four-Wheel-Drive" warning appeared. I was just down the road from my house, so I pulled into the driveway and put the car in park, but it wouldn’t turn off. I realized the parking brake was engaged and wouldn’t release either. I was stuck in two-wheel drive and couldn’t switch to four-wheel drive, and the emergency brake wouldn't disengage when I pressed the button, so the vehicle still wouldn't shut off. I had to put it in reverse physically step on the gas, which Is the only way The parking brake finally disengaged And allowed the vehicle to shut off.

While driving on the highway, the vehicle suddenly downshifted and shut down and would not restart. All lights appeared on the cluster and showed "conditions not correct for shift". Had to have vehicle towed from the side of the road and wasn't even able to shift into neutral.

*Total Engine Destruction from Thrust Bearing Failure (GM Bulletin 25-NA-307) * Yes, failure has been confirmed at Chevy Dealership (Davis Chevrolet Gainesville FL) * Yes, problem has been reproduced at dealership *Only the dealer service department has confirmed failure *No warning lights, thrust bearing failed sending shrapnel into the bell housing torque converter just loud metal clanging noise from bellhousing area *GM knows of the problem but will not recall just handling them at dealerships as they fail *Had this happened in an isolated area it would have left us stranded in the middle of no where * I am awaiting the service order from the dealer in PDF form and can send upon request! *As for now I have a 4 month old $90,000 Tahoe in the shop waiting on an engine!

Dealer grounded vehicle for excessive crankshaft play due to thrust bearing failure. Been without vehicle since 1-20-2026 and although I have received 2 text from service manager I have not been told when I will get vehicle back. Mileage was at 4,820. Vehicle build date 7/25

2025 Chevy Tahoe: While approaching a traffic stop I hit the brake pedal and this would not work nor stopped the car. The pedal went all the way to the floor and would not work anymore. I believe the Emergency Brake activated and managed to stop the car. i was driving at The Check Engine warning light was immediately activated along with the following warnings: *Service Brake Assist *Check trailer Brake Lamps *Service Steering Column Lock *Service Traction Control *Service ESC *Service Brake Pad Monitor *Trailer Brake Disabled Service Required

While I was driving, my vehicle suddenly lost all power I encountered a misfire with the engine light flashing, and diagnostic codes P0353 and P0300 indicated a misfire on cylinder three. The coil pack and spark plugs for that cylinder were replaced, yet issues persist and problems continue. There is a strange popping and cracking noise coming from my dash. My brakes are also making it loud sound randomly when pressing on breaks yet brake pads are fine

My 2025 Chevrolet Tahoe Z71 3.0L LZO Duramax with approx. 3,380 miles experienced a sudden and complete engine failure while towing my camper on the interstate at night, in the rain, while traveling alone 375 miles from home. The vehicle lost power, displayed warnings, and became inoperable, forcing me onto the shoulder in unsafe conditions. The engine has been diagnosed as requiring full replacement due to a defective crank end play / thrust bearing, under Technical Service Bulletin (TSB) 25-NA-307. This is a significant safety concern for a new vehicle and could have caused a crash. GM has multiple documented issues with this model year, and the car has also experienced unresolved infotainment defects, as outlined in TSB #PIT6393F. Requesting NHTSA to investigate a potential safety defect.

I was driving up to a border check point and slowed down at the guard shack. Once cleared I released the brake and tried to accelerate. The vehicle shut down completely. I tried to restart it and the check transmission warning came on. The vehicle would not restart. I was blocking the lane at the border check. After a few minutes I was able to start the vehicle and limp over to the shoulder of the freeway. There was no power and loud knocking and squealing from the engine compartment. Engine light came on and several other warning lights that I don't recall. I was in the desert with 3 dogs in an unsafe area for 7 hours until I could get help. Vehicle was towed to the dealership and is currently under diagnosis but so far code P0016 and metal pieces in the oil.

When backing up the auto braking brakes very hard sudden stop without warning even though no objects near by. Appears to be from shadows and made worse when it is raining and the camera has water on the lense. I turned off the backup auto braking and it still does it. It brakes hard enough that it pinched a nerve in my neck causing sudden pain which chipped a tooth

After my vehicle experienced a brake system failure 3 weeks ago and I got my vehicle back from the dealership. I noticed that my vehicle has no emergency brake so in the event of this failure and/or future brake system failures there was no way to stop my vehicle. Their emergency brake is technically a parking brake that can only be applied when the vehicle is completely stopped. I'm not sure how a vehicle this unsafe would be even legally sold or allowed to operate on the roads.

Brake system failure. Brakes were all but gone as I couldn't safely stop my car at an intersection and had to quickly cut in front of on coming traffic to go into a gas station to avoid running a red light.

Driving along the highway in cruise control at about 70mph without any trailer being pulled. Suddenly I got brake errors. ABS, ESC, Trailer brake error failures all popped on the dash warnings. Brakes were unresponsive only applying hard pressure to the brake pedal was effective. There was zero feedback from the brake pedal to myself on it engaging and braking effectively. If this happened in a situation requiring more immediate braking, I would not have been able to figure out the braking capability of my vehicle in time. There were no issues with my vehicle at the time. I see that similar issues have been reported on Facebook "Chevy Tahoe Owners Group". Unknown whether it's a sensors glitch or a SW issue. After a few hours of being parked the car brake system started to work properly again. Made an appointment to check out they system at the dealership.

Complete engine failure.

4/24 The check engine light was flashing and the car went into limp mode and the display noted to pull over for safety. On 4/25 We took the car to the dealer they did some reprogramming. On 4/26 the vehicle keeps loosing power when driving.. Scheduled another appointment on 4/28 to have vehicle looked at.

Bought the 2025 Chevy Tahoe, had about 680 miles on it. 400 of which were from the dealership. Had the pleasure of driving it for a week. Check engine light came on and was told that the transmission valve body had gone bad. The issue regarding that particular transmission has existed since 2019. However the part needed is allegedly on back order, and GM has no idea when they will get that part in.

I was driving and the driver dash frozen. I couldn't tell my speed, it didn't indicate blinker or hazards. It would say i was in "D" when the car was parked. The center dash shut down completely. The seat belt indicator didn't work, none of the charging ports worked. **THIS IS A RENTAL CAR**** I do have video of the dash.
