2019 CHEVROLET TAHOE Complaints

On 10/23/24 the vehicle's 6.2 L L87 engine seized while driving on a state highway (similar to the later models already under recall) putting myself and other drivers at risk through a sudden loss of power and speed. The component was inspected at a GM dealership and then replaced AT MY COST. The replacing mechanic said the failure was in the rod bearings (the same as in the recalled engines). There were no warnings or related problems prior to the sudden failure. The existing recall ( Investigation:PE25001) needs to be expanded to these earlier model (2019 and 2020) engines that have the exact same issue.

While attempting to accelerate to merge onto interstate/freeway from highway speed of 55mph, experienced significant engine misfire & loss of speed. This happened less than 40 days after purchase of this used vehicle from local dealership, with 30 day "warranty". Vehicle is currently NOT safe to drive.

I purchased my 2019 Chevrolet Tahoe in April of 2019 with 4 miles on the dashboard. My vehicle is Currently in the shop where I purchased the vehicle. It’s been there going on 3 weeks now. I was driving and my vehicle started losing power. I’m traveling on the highway at the time and my vehicle engine light came on as well and I couldn’t go over 30 without the vehicle losing power. I pulled over just in time before it shut down almost causing an accident .I have been servicing this vehicle 4 months after purchasing it. I’ve had better at a buy here pay here lot. And now I’m without a vehicle due to the Liner needs replacing. I was told they had to drop the entire motor to do so. My vehicle has 80,000 + now and I definitely shouldn’t be replacing this component. There are other things going on as well but I’m unaware of the name. Also I purchased Every warranty there was to buy when I purchased this vehicle and the dealership failed to acknowledge any one of them. So lucky I had another warranty company to bag me up and they are the ones paying this 4to 5,000 dollars repair. I’ve also had to service the Trailer brake system several times.. NEVER used it since I’ve had the vehicle.. until I asked them to just disconnect it because it wouldn’t stop. Also 4 months of having the very.. the custom rims ( back passenger side) broke from the inside almost causing me to go into ongoing traffic on the opposite side of the road.. and nearly flip. Meanwhile All this is coming out of my pocket to fix.. except for this engine repair.. but I do pay the deductible. Many is telling me to get an attorney. But I reached out 1st since I seen where there is a recall but it’s not saying my year of vehicle. Please help. Also. I’m still receiving my oil changes from the dealership. And I get them on a regular. NOTE: The shop that has my vehicle is Not the one listed on the document. But this is what the diagnostic read. And this is what’s being done to my vehicle.

Purchased a used (128k miles) 2019 Chevrolet Tahoe LT. First month of driving (not for everyday use) noticed some strange transmission and engine hesitations when reversing. Notified the dealership and was told the transmission needed reprogramming. They reprogrammed and the problem though less noticeable, still persisted. Contacted the local and the purchased dealership to let them know of the persistent issues. Purchase dealership had me bring the vehicle back where I was told the vehicle needed a new transmission. Vehicle had less than 600 miles since my purchase. I was told it was $10k and I was liable due to the expiration of the limited warranty. Let them know these issues were identified and not fixed during the warranty period. Dealers fixed the vehicle but still charged me almost $4k. With the new transmission in place, I still noticed an engine hesitation, as if it was missing. Had new plugs installed but still no luck. Was told that cylinder deactivation may have caused lifter issues. Took it to my local dealer and thought the issue was obvious, they said they couldn’t find the issue. I was charged $300 for a non diagnosis or fix. The issue still persist

I removed the carrier from my vehicle to clean below it and found two parts on the base that connect the seat / carrier to the base are broken.

Not power, lot blue smoke, excessive consumption of engine oil, noise in the motor, like something is broken in it.

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.

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.
