2019 CHEVROLET TAHOE Engine Problems

My 2019 Chevrolet Tahoe Premier equipped with the 6.2L V8 engine has experienced a major internal engine failure. The dealership diagnosed camshaft bearing failure with a recorded misfire on cylinder #5. The engine oil was drained and inspected and no significant metallic debris was found, and the dealership noted no evidence of abuse or neglect. Intermittent drivability concerns were present over the life of the vehicle and were addressed through professional diagnosis and repair each time. The vehicle has been properly maintained since new. Just months prior to this failure, the vehicle underwent full diagnostics and significant repairs, and no internal engine failure was identified. This failure appears consistent with a known defect pattern affecting GM 6.2L engines involving internal valvetrain or camshaft-related failures. The failure resulted in abnormal engine noise, misfire, loss of power, and the vehicle becoming unreliable for safe operation. General Motors has declined goodwill assistance citing warranty expiration, despite the nature of the failure being a non-wear internal engine defect. I am submitting this complaint so this VIN and failure can be reviewed as part of any ongoing investigation into 6.2L engine failures.

I also had this issue with my prior gmc 2017 yukon until i traded it in.. My currently 2019 chevy tahoe premier has always had services done when required with milage needed. My issue While driving viechle on freeway knocking with shaking sound in engine. Engine light would turn on. Even though with tune-ups oil changes done this problem still continued. Now my car is sitting on driveway and cant drive it

Alignment and suspend has vehicle shaking,rumbling and shifts all over when hitting a bump in road. J.B.A. Chevrolet had detected alignment/suspension problem. Had check engine light come on but Carmax claimed it was a history code. The transmission had to be replaced. Still experiencing multiple problems with said vehicle.

Loss of power

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 2019 Chevy Tahoe at 92000 miles is having lifter problems and a failing engine due to the DFM system. This is a 5.3L V8.

Active Fuel Management for the automobile variable displacement technology was the issue. 6.2L V8 L87 engine has created the following issues- Cylinder deactivation issues transmission issues Multiple camshaft issues include camshaft lift issues Fuel system problems

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.

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.

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.

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

Lot white smoke for tail pipe, noise came in the motor, leak gas for tailpipe

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

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.

This vehicle is owned by the City of Fort Lauderdale Police Department. We are submitting complaints for multiple Tahoe's that have stopped during operation causing extreme danger to our staff and other drivers in the city. The cause is always bad fuel pumps and our units have had to have the pumps replaced in some cases multiple times. 7-5-23 Cause- Performed DTC scan and found coed P2635 which signifies Fuel pump A Low flow/ performance. With key on, engine off I used a scan tool to command the fuel pump on while monitoring the fuel pressure sensor parameter and found that the fuel pressure was below specifications of 46-84 psi. Inspected fuel pump assembly and connector and no faults were found. Test results verified faulty fuel pump replacement needed at this time! 4-2-24 Check engine light went on & Car shut off out of nowhere. scan engine for codes and found codes p2535 and code po300 fuel pump pressure under performance replaced fuel pump

the vehicles have a serious defect that causes the air conditioning systems to crack and leak refrigerant, lose pressure, and fail to function properly to provide cooled air into the vehicles. These failures lead owners and lessees to incur significant costs for repair, often successive repairs as the repaired parts prove defective as well. As summer temperatures in many regions soar into triple digits, this leaves Escalade, Sierra, Suburban, Tahoe, Silverado, Sierra and Yukon owners with vehicles they say are undriveable due to concerns about child, pet, and driver safety. I would hope GM will cover this AC problem since I am just outside of my certified warranty and have kept up with all maintenance requirements per manual. See link below that I have found to be a common problem with the condenser. I am not a happy customer here, definitely deters me from buying another Chevy/GMC if GM does not cover the cost under warranty. Per link below you have to constantly contact GM to argue this common problem to get them to agree to cover it. I had it diagnosed by Hoselton Fairport NY last Tuesday, they wanted $400 just to touch my AC to start the diagnosis and to put a $40 can of Freon in it. It didn’t hold after 3 days. I had my brakes done. 2019 Chevy Tahoe. Also lawsuits going on about faulty condenser. If anyone else has this issue I would definitely suggest contacting GM CS before forking over $1200+. It was a bit of a [XXX] with all the phone [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle will stall while parked causing a strong odor of gasoline. Takes several minutes of sitting with vehicle off before it will start again. The vehicle has also done this while coming to a stop. This vehicle has 41000 miles on it and continues to do this. It is used for law enforcement agency. I am required to respond to calls and this hinders response times to calls as well as emergent responses. The dealership has looked at the issue and blamed it on fuel having water in the fuel. They have replaced several items involving the fuel system. This has not solved the problem. Bob Ruwarts has not given an answer.

While driving on the freeway truck had lost all power and steering and braking capacity. The screen on dash went completely black with no warning signs. Vehicle could not accelerate and or brake other than drift in lane. Vehicle was without power for a brief time until power came back was able to not crash vehicle as this happened at a high rate on speed on busy freeway. When power did engage back on the dash lights now were full brightness and no control to dim it down could have been sign of definitely Electrical issues. This had occurred several times since it had this major problem! I then urgently took my vehicle to specific Chevy dealership for service and was refused service at dealership for the major electronic black out. I had no other choice but I then had contact Chevy customer service line to bring them this major problem four months ago. To this current day I still haven’t had any support or assistance in addressing this major problem with my vehicle! Chevy support or lack there of has only delayed addressing my to get serviced to see what’s causing this problems!
