2019 Chevrolet Tahoe Engine Problems

Your engine's valve lifters have failed, requiring a complete engine replacement that costs around $15,000 according to GM service. You've owned the vehicle for one year and it's been sitting unused since the problem occurred. GM has not issued a recall or warranty coverage for this issue, and you report that many other owners are experiencing the same problem.

Your engine seized and made a loud noise when you tried to start it after an engine valve lifter failed. The vehicle was regularly serviced before this happened. Fixing this will likely require replacing the valve lifter and potentially inspecting the engine for any damage caused by the seizure.

Your engine has completely failed for the second time, with a bent connecting rod in cylinder 4, and damage to cylinder 7 and the camshaft. The engine shut down while you were driving on a busy highway, forcing you to navigate across five lanes of traffic to reach the shoulder—a serious safety hazard. The manufacturer has confirmed this is a known issue with a technical bulletin on file, and you have service records documenting both failures.

Your 2019 Tahoe's 6.2L V8 engine experienced a camshaft bearing failure, causing misfires, rough running, and loss of power despite regular maintenance and no signs of abuse. The dealership found no metal debris in the oil and had just completed diagnostics months before, but GM declined to cover the repair under warranty. This repair will likely require significant engine work, possibly including camshaft and bearing replacement or full engine overhaul.

Your engine makes a knocking sound with shaking while driving on the freeway, and your check engine light comes on. Despite regular maintenance including tune-ups and oil changes, the problem persists and your car is no longer drivable. The issue may require diagnostic scanning to identify the underlying engine problem and possible repair or replacement of affected engine components.

Your 2019 Chevrolet Tahoe is consuming excessive amounts of engine oil and stalling while shifting gears at low speeds, even though no warning lights appear on the dashboard. Multiple mechanics have confirmed the problem is engine-related, though your vehicle's VIN was not included in a related recall campaign. The issue will likely require a full engine diagnostic and possibly internal engine repairs to address the oil consumption and stalling.

Your engine is losing power during acceleration or operation. This could mean your vehicle won't accelerate as quickly or strongly as it should when you need it to. You should have this diagnosed soon, as it may indicate a fuel delivery, ignition, or engine management system issue that could leave you stranded.

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.

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.

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.

MY VEHICLE IDLING IS MISSING I ASK DEALER TO CHECK IT WHEN I RECENTLY HAD OIL CHANGE. DEALER REPORTS BAD MOTOR MOUNTS REQUIRING MOTOR AND TRANSMISSION REMOVAL. I HAVE A NEW VEHICLE YET IT NEEDS MAJOR REPAIR.
