2019 CHEVROLET TAHOE Power Train Problems

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 the vehicle was consuming an excessive amount of engine oil.

The vehicle was taken to three independent mechanic,s who indicated that the failure was related to the engine. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 120,000.

While driving on the expressway I heard a rattling noise coming from my undercarriage, by the time I got off my exit the sound got louder, I attempted to make it home and when I pulled in my driveway, and popped the hood, fluid starting pouring out the bottom as well as splashed on other components. Upon further inspection it was determined that the fluid was coolant. There was no dashboards lights or warning signs indicating that something was wrong or that my car was at risk of overheating. I had the vehicle towed to an auto repair shop and the following was diagnosed and repaired: •Water pump •Cooling System •Engine Water pump •Engine Coolant thermostat housing assembly. •Serpentine Belt

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.

In March of 2023, my 2019 Chevy Tahoe began having episodes where while driving there would be no gas power. The needle on the speedometer would start dropping to zero and the truck would sound like it was in neutral without notice putting everyon in the vehicle and outside of the vehicle at risk. My kids travel long distance for their AAA sports. Then all of a sudden there would be a loud noise (sound like hitting a rock with a sledge hammer) and you would feel the jarring noise and it would engage again. It was taken into the dealer and they found nothing wrong with it, couldn't duplicate the problem. This was at approximately 128,000 miles. On and off it happened all from March through April 2023 without notice, on the expressway traveling at 70 mph and having no control over the speed of the vehicle. In April, it became more apparent that when you hit 50 mph and 70 mph it was happening on cue, at 130,000 miles. Took it to the dealer again in April 2023, gave them the information and all they told me was that it was the transmission, $12,000 and it would be $500 to just take it apart to confirm, no error code was scanning and if I wanted to trade it in they would get a sales person. I spoke with the sales person who couldn't help because the balance on the loan is $28,000. Went back to the sales to get the car and a different service person helped me and couldn't find the truck. The truck had never been entered into anything in the service department. I took the truck home and it has sat in my driveway. It is a shame that you purchase a $70,000 vehicle and cannot get quality service from the dealer and a vehicle that doesn't make it past 130,000 miles. We have a 2013 Ford Edge that has 358,000 miles on it. What does that say about Chevy currently? Currently I have been starting the vehicle and driving it down my block and back daily to keep it from deteriorating, it cannot go over 20 mph without the gas power failing. I am hoping someone can help.

Sudden and unexpected loss of power steering several times. In all cases, the loss of power steering has happened when starting the car. Turning the ignition off and immediately on again did not resolve the issue. Turning the ignition off and letting the car sit for 10 minutes before re-starting the car appeared to resolve the issue. The vehicle has been inspected several times by the service department of Mayer Chevrolet in St. Petersburg, Florida, who has been unable to replicate the issue and therefore has responded that they are unable to resolve the issue. GM has issued a recall for the same issue that has been identified on the 2021 Chevrolet Tahoe and other related GM vehicles, recognizing there is an issue, but no recall exists for the 2019 Tahoe. Issue continues to happen every few months.
