2017 CHEVROLET TAHOE Complaints

January 23, 2023 - mileage (85K) 2017 Chevy Tahoe, Z71 What: Transmission/Drive Train 6L80 Hydromatic Transmission - Complete Failure Vehicle was idling in park, in a parking lot, as it was put into drive there was a loud clunk, then pressing the accelerator the vehicle would not move. Put the vehicle back in park, then reverse, this time the transmission engaged backwards, shifted to drive, it moved normally pulled out into traffic. Safety was put at risk when pulling into traffic and then being in the traffic and suddenly, pressing the accelerator the car was no longer moving forward, with other vehicles coming in the rear. Immediately I put on the flashers, bringing the vehicle to a complete stop in traffic in the middle of the lane as the vehicle would not move at all. This put me in danger of being rear-ended by the vehicle(s) behind me. Additionally, safety could have been at all times depending on situation and location. Managed to limp the vehicle home, where it sat overnight to drive to the dealership for diagnosis. No issues going from cold start to drive to travel 4 miles to the dealership, Mark Wahlberg Chevy. Dealership Service Diagnosis, complete transmission failure, likely torque converter issue (known problem), entire transmission was replaced with remanufactured. Warranty, just expired December 2022. Removing transmission, damaged muffler, had to be replaced. Reported to the GM manufacturer for assistance to replace transmission as the warranty just expired in December of 2022. GM Case number 9-xxxxxx filed on January 26, 2023. GM as far as I know did not come and see the vehicle. The old transmission is still at the dealership, I intend to take possession of it. There was no previous notice that this even was going to occur, no lamps, signs, check engine light, symptoms no were there any error codes produced just prior to this event nor do I believe at the time the vehicle arrived at the dealership on January 26.

The vehicle was not diagnosed nor repaired by a dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 69,000.

Left stranded when vehicle stopped running at a stop light due to bad transmission.

When pulling out of my driveway my gas pedal foot became stuck on the gas pedal. I could not remove my foot from the gas pedal. I immediately stepped on the brake pedal and then my Tahoe accelerated rapidly. I removed my foot from the brake pedal because any pressure on the brake just caused the car to accelerate faster. I then managed to wiggle my gas pedal foot from off of the gas pedal, it took a lot of effort. I was wearing normal men's shoes with no protrusions of any kind. I have recently seen in the news several similar occurrences including one that resulted in a fatality and others being injured as the car accelerated into an Apple store. In two of these cases that I've seen in the news the drivers have reported that their foot became stuck on the gas pedal and when they applied the brakes the car accelerated out of control. This is exactly what happened to me except i managed to get the car under control before I hit anything. My inspection of the Tahoe's pedals revealed that the two pedals are very close to each other and when applying the brakes the brake pedal comes down on the foot that is somehow stuck on the gas pedal. I believe the stuck accelerator foot was somehow trapped under the brake pedal. The pedals are too close together.

While driving in a parking lot to go thru a drive thru to pick food I was moving at a slow speed 10 to 15 mph and slowing to a stop my brake pedal became very hard to push and my Tahoe did not stop right away. I almost hit the car in front of me. I put the vehicle in park, turned it off, waited 30 to 45 seconds, turned the vehicle back on and put it in drive and slowly started moving in the drive thru line. When I stepped on the brakes to stop again the pedal got hard to push again and it did not stop right away. Brake Assist warning came on in the dashboard when I moved and tried to stop again. I drove home with extreme caution and as I was rolling into my driveway the same thing happened again that happened in the drive thru. I have parked my Tahoe and will have it towed to dealership.

HARD BRAKE PEDAL RESULTING IN LITTLE OR NO STOPPING POWER WHEN APPLYING THE BRAKES AT LOW SPEED. TO GET THE VEHICLE TO STOP, YOU MUST STOMP ON THE PEDAL AS HARD AS YOU CAN. THE SITUATION TYPICALLY OCCURS WHEN PARKING. THE BRAKE APPLICATION OR TWO ARE FINE, BUT AFTER THAT THE BRAKES FAIL. AND ALSO MAKE A VIBERATION IN THE BRAKE PEDAL WHILE SOUNDING ROUGH! WAS DRIVING TO WORK AND BRAKES PEDAL WENT TO THE FLOOR WITH NO PRESSURE AT THE PEDAL.

When driving at low speeds, the brakes are hard to engage which can result in crashing into objects/people without being able to safely stop. This happens in parking lots, stop and go traffic on the busy interstate and in drive-thrus. This can be dangerous for the driver/passengers and others outside the vehicle or objects. This is also a huge safety issue when driving down a steep incline at low speeds and having to pull out into traffic due to it not stopping appropriately. Vehicle has been inspected by a mechanic however there are no warning lamps illuminated. As stated before, brake issue happens only at low speeds. From my understanding there was a recall for this same issue for vehicles of certain years 2015-2018, specifically Tahoe being in the category.

Tahoe brake system failing, takes longer to stop. Brake pedal begins to feel solid on activation with little effect to slow or stop. Due to failure to stop, Almost in a few collisions and rolled down a hillside road. Tahoe is now parked. I read the 2014-2018 tahoes have a (brake) vacuum pump issue for recall. 19V645000 Recall number Called local dealership. Is not on recall list. Not submitted to dealership yet. No appointments until January 2023. I’m sure they can reproduce issue Tahoe not inspected by others No warning lights or other in vehicle advisals

Weird shifting Vehicle going neutral out of nowhere while operating the vehicle in traffic (major safety issue)! No codes alerting of any damage Could not go over 20 mph without vehicle completely stalling in traffic No matter how much accelerator pedal was engaged vehicle would not accelerate
