2019 Chevrolet Tahoe Power Train

The contact owns a 2019 Chevrolet Tahoe. The contact stated that while driving at an undisclosed speed, the vehicle unexpectedly stalled while attempting to shift gears. There was no warning light illuminated. The vehicle was able to be restarted. The vehicle was towed to an independent mechanic, where it was diagnosed that metal shavings were found in the transmission, causing the transmission to fail. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The dealer was not contacted. The manufacturer was made aware of the failure. The approximate failure mileage was 127,000.

Ticking sound started from the motor and the check engine light came on. We took it to the dealership and was informed the vehicle had bad lifters with a bent push rod needing a full motor replacement. The vehicle has 92k miles and was purchased a year and a half ago from that same dealership. The vehicle is currently at the dealership awaiting costly repairs.

The automatic transmission on my 2019 Chevrolet Tahoe has failed prematurely at approximately 88,000 miles. The dealership confirmed internal transmission damage, specifically that Solenoid #3 in the valve body is sticking and not engaging, which requires a complete transmission replacement. Their written inspection states: “Possible internal damage in transmission. Solenoid 3 in valve body is not engaging.” The component is available for inspection upon request. Safety Risk: This malfunction created several dangerous situations. The vehicle hesitated, struggled to shift into gear, and at times moved forward while in reverse. These symptoms could cause loss of control, delayed acceleration when entering traffic, or unexpected movement putting myself and others at risk. Diagnosis Confirmation: Yes. The problem has been fully inspected, reproduced, and confirmed by an authorized Chevrolet dealership service center. They provided a written estimate of 8,669.59 for a complete transmission replacement. Inspection by Others: The transmission has been inspected by the dealership where the vehicle was purchased. No independent mechanic, police, or insurance representative has inspected it yet, but the dealership’s findings are available. Warning Lamps or Symptoms: Prior to the failure, I experienced hesitation, difficulty engaging gears, harsh shifting, and the vehicle lunging forward while in reverse. Shortly after these symptoms appeared, both the check engine light and tire pressure light came on. Additional Context: GM has released multiple Technical Service Bulletins (TSBs), including 19-NA-153 and 21-NA-199, addressing known issues with their 8-speed transmissions such as harsh shifting, slipping, and valve body/solenoid problems. This suggests a broader pattern of defects. GM and the dealership offered only 10% goodwill assistance, leaving almost the entire repair cost to the consumer, despite this being an internal mechanical defect with normal personal use.

The contact owns a 2019 Chevrolet Tahoe. The contact stated that while driving approximately 25-30 MPH, a message advising that the transmission fluid was overheating and to pull over was displayed. The contact coasted to the side of the road where, the vehicle became inoperable. The vehicle was towed to a certified mechanic, who diagnosed that the transmission fluid was burnt, causing the transmission to slip while switching gears. The mechanic informed the contact that the failure was a known issue and to contact the dealer. The dealer was contacted and informed the contact the VIN was not included in a recall. The vehicle was not repaired. The manufacturer was informed of the failure and confirmed that the VIN was not included in a recall. The manufacturer referred the contact to the NHTSA Hotline to file a vehicle safety complaint. The failure mileage was 100,000.

When slowing down and accelerating there is a shutter and a jerk to my transmission. While I am driving the shuttering is sometimes so loud I can hear it over the radio and it is a vibration motion.

Transmission needed replacing at 110,000 miles. Torque converter went bad

Driving on the interstate when all the sudden there was no power to drive train, the rpm gauge red lined. I put gear shift to neutral and rpm gauge came down, at this time no check engine light. Coasted to exit and parked. Got out and look around Tahoe for damage none found, looked under hood and no damage or fluid anywhere, none found. Got back in Tahoe and shifted into drive. I drove on 2-line highway to nearby town; 25 mph is all it would go. There was not a chevy dealer in town, stop at a Ford dealership and they sent me to an independent shop. Check engine light came on as I drove to independent dealer. Independent dealer checked for codes found transmission he checked fluid level it was full, but fluid smelled burnt and had metal shavings. He pulled it into shop and dropped fluid pan, to visually verify transmission parts were bad. He had to install a new gm transmission.
