2019 Cadillac Escalade problems

“Vehicle: 2019 Cadillac Escalade ESV VIN: [XXX] Engine: 6.2L V8 L86 Mileage: Less than 59,000 miles I am reporting a serious premature engine failure involving the 6.2L L86 engine in my 2019 Cadillac Escalade ESV. The vehicle has been properly maintained with regular oil changes and routine service. On September 8, 2026, the vehicle developed a chirping sound during startup. After driving, the chirping stopped, but a ticking noise occurred when the vehicle was restarted. I immediately had the vehicle evaluated by an independent mechanic. The mechanic kept the vehicle for two nights so that a cold-start evaluation could be performed. On September 10, I was informed that the engine noise was caused by lifter failure. The vehicle was then towed to a Cadillac dealership in [XXX]. On XXX, the Cadillac dealership diagnosed lifter failure and camshaft damage. The vehicle had not experienced a loss of oil pressure, noticeable loss of power, hesitation, or other significant warning symptoms before the failure. I am concerned because General Motors has issued technical service bulletins addressing lifter failures and ticking noises involving the 6.2L L86 engine and the…”

“I am filing a safety complaint regarding my Cadillac Escalade due to a transmission/valve body failure occurring at approximately 77,100 miles. The vehicle began experiencing transmission-related issues including harsh shifting, hesitation, abnormal operation, and unsafe drivability concerns. The vehicle was diagnosed by the repair facility as requiring a transmission valve body replacement. I was then informed that the required valve body is currently on national backorder with General Motors, and my vehicle has now been out of service for over two months with no estimated repair completion date available. After researching the issue, I discovered numerous other GM owners reporting similar transmission valve body failures involving Cadillac Escalades and other GM full-size SUVs and trucks equipped with similar transmissions. The widespread nature of the failures and the nationwide parts shortage raise serious concerns regarding reliability and potential safety defects. This issue creates a significant safety concern because transmission failure can affect acceleration, shifting, drivability, and the vehicle’s ability to operate safely in traffic conditions. I…”

“Odometer Fraud. The contact purchased a 2019 Cadillac Escalade ESV on November 5, 2025, from a private dealer. The contact stated that upon having a State Inspection performed on the vehicle, the vehicle failed the inspection. The mechanic stated that the amount of mechanical work needed to repair the vehicle did not match the low mileage on the vehicle. The contact then obtained a Carfax Report and discovered the mileage discrepancy. At the time of purchase, the vehicle mileage was 65,800; however, the Carfax report discovered that the mileage was 237,000 in September of 2025. The contact reported the issue to the Maryland Department of Motor Vehicles and the Virginia Department of Motor Vehicles. In addition, the contact reported the issue to the Howard Police Department and the Howard County District Attorney of Maryland. After having the cases dropped by the various agencies, the contact called U.S. Immigration and Customs Enforcement and was referred to the NHTSA to report the issue.”

Diagnostics/Repair work was done by Reliable GMC/Cadillac of Roseville to fix an ignition coil that was giving the engine error code. 2/24/26 At 86,697 miles, I began having rough idle worse than before, loss of power when accelerating and driving, knocking sounds that increased with acceleration in RPMs as well as a blinking engine warning light. All spark plugs and wiring were changed by Cadillac which resolved engine error codes for misfire. Diagnostics/Repair was done by Reliable GMC/Cadillac of Roseville. 3/30/26 at 87,246 (only 549 miles since the previous work up,) the car began to idle rough, and have a audible rhythmic tapping and knocking when accelerating and increasing RPMs. During driving, I experienced flashing engine light, and then sudden loss of power and control of vehicle. 3/30/26 Veh towed toThompson GMC, of Placerville, CA diagnosed vehicle with full engine failure from broken connecting rods and crankshaft of engine.…”

“My wife and I purchased this vehicle in 2023 with 33,xxx miles on it and since we’ve had it, the vehicle has locked itself with the key fob inside 3 different times, we’re going on the third suspension replacement with normal driving that is ruining alignment and tires, we’ve had multiple issues with the computer system resetting itself and not acting appropriately, key fob not working, seat heaters in the back turning themselves on, and glove box randomly opening. Yesterday, my wife tried to start the car and everything on the dash just started flashing, the vehicle attempted to turn over and made terrible knocking noises in the engine compartment. The final straw for us was on July 13th when my wife placed our then 7 month old son in the car after church with the remote start feature working, placed his diaper bag in the vehicle with keys inside the bag, and as she walked around to the driver door, the vehicle locked itself and shut off in 103*F heat. My son began screaming and the vehicle would not unlock. My wife was forced to punch the window out, lacerating her hand open, and even after peeling the window out, the vehicle still would not unlock even…”

“This vehicle was sold to me with severe frame damage, which was not reported on the carfax, and was not reported at the dealership. If you turn the steering wheel to the right, you will hear a scraping noise under the right front tire, as the suspension is off because of the frame damage caused from an accident with the previous owner. I returned the car for a refund, however the car is being sold again at a different dealership and there is no reports of any frame damage.”
