2019 Cadillac Escalade

All of a sudden the car just died while driving it on the road at speed. There was no warning or indication of an issue. It just shook and then died. It would not restart. This is an egregious safety issue and should not happen on a vehicle with only this many miles. We could have been killed if we were on a highway. A quick google search shows this is a KNOWN issue. The mechanic said this is a know issue with this engine - Please get a recall out for 2019 before someone dies!!!!

The AFM lifters on 1,7,4,6 cylinders go out with no warning causing shuttering and misfires. Scary! This is the second Escalade with the problem and the 2019 engine has occurred twice in 6 months. I have inserted a lockout device to prevent the vehicle from going into 4 cylinder mode since the last episode (6 months ago) and it still failed another AFM lifter. GM said they will fix the 3rd one under warranty but no guarantees it won't fail again. Who knows where I might be? I am without a vehicle for 2 to 3 weeks at a time. GM will not remove the system and replace the cam and lifters (even if I purchase the parts). POOR service also.

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 am requesting that NHTSA investigate these transmission valve body failures and the related nationwide parts shortage affecting GM vehicles.

MY VEHICLE LOST POWER SUDDENLY I ALMOST GOT HIT FROM BEHIND LUCKILY I WAS ABLE TO AVOID A ACCIDENT TOWED TO MECANIC TOLD ME COMMON ISSUE WITH THIS ENGINE MY ENGINE NEEDS REPLACMENT

Loud engine knocking heard after starting vehicle at grocery store, vehicle was driven 25 miles to get to store so was 'warm', check engine lite on dashboard came on during knocking, was able to drive vehicle to dealership for diagnosis (approximately 3.1 miles), dealership diagnosis after engine teardown was roller lifter failure causing damaged camshaft, instead of repairing defective parts in this engine opted for new engine replacement, cost approximately $15,000 for repairs and labor out of pocket, vehicle is 2019 Escalade, less than 110,000 miles on engine, purchased in 2022 with approximately 9000 odometer miles from cadillac dealership, professionally maintained at Cadillac dealership since purchase. GMC has a NHTSA recall (EA25007) for 6.2L V8 engines (which this vehicle particular has), for the years 2021-2024. Model years 2019-2021 with these type of engines has an active investigation (no recall yet) for the same issue of 'loss of motive power due to engine failure'. We were fortunate that the failure occurred in town at low speed driving and not on the freeway with truck traffic at 75 mph, a sudden loss of power due to engine failure would greatly have increased the risk of a crash.

Loud knocking sound in the engine appeared out of nowhere. This is the same engine as what exists in the 2021 year models which does have a recall on them, but for some reason the 2019 models like I have are not included in the recall. I cannot drive the car for fear of the engine seizing up.

The engine has an Active Fuel Management system that has frequent failures of the lifters which causes the push rods to bend. This causes a misfire and the check engine light to illuminate. A broken piece of material entered the lower portion of the engine which could have caused an engine failure while on the highway. I had the vehicle towed to a dealership before a catastrophic failure occurred. Cadillac refuses to warranty this defect when the engine reaches 70k miles. The dealership sees this often and replaced the lifters on only one bank (head) at the cost of $4,000. This occurred on my 2018 Escalade which was under warranty at the time. They had to replace the camshaft and all the lifters on that vehicle.

Lifters failed and needed repaired. $2,000 mechanic bill

The engine valvetrain is suspected, specifically an AFM (Active Fuel Management) lifter or related lifter/oil control component. The vehicle and affected components are intact and available for inspection upon request. An unresolved internal engine malfunction presents a risk of sudden power loss, engine damage, or stalling while driving, which could increase the risk of a collision, particularly at highway speeds or in traffic. The issue has been reproduced consistently by the vehicle owner. Diagnostic work has been performed by independent parties, including inspection of the exhaust system, belts, and valvetrain components. Further confirmation by a dealer has not yet occurred. The vehicle has not yet been inspected by the manufacturer, police, or insurance representatives. Independent mechanical inspection and repairs have been performed. No warning lamps or messages were displayed. Symptoms include a delayed chirping/ticking noise beginning approximately 20–30 seconds after engine startup, which is repeatable and changes with engine load and cylinder deactivation behavior.

The contact owns a 2019 Cadillac Escalade. The contact stated that there was an abnormal whining sound coming from the engine with the check engine warning light illuminated on the instrument panel. The vehicle was taken to dealer; however, the dealer was unable to duplicate a failure. Recently, the contact stated that the check engine warning light illuminated on the instrument panel. The manufacturer was not notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 48,000.

2019 GM Cadillac Escalade 6.2-liter L87 engine rod/bearing knocking noise for second time causing fear of driving and long range usability because of catastrophic failures reported. GM says out of warranty and not their problem and not part of the issued recall years for bad L87 engines. Vehicle engine repaired under warranty 03/07-2024 for bad camshaft and lifter failure at a cost of $8776.63.

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 manually. I had to leave my fire station to meet her at the hospital where she received stitches. Cadillac sent out an inspector on 8/17/25 and we still have not heard anything back. I have filed with the BBB Auto Line as well. There was never any warning lights or messages, other than repeated “service suspension system” warnings, which has been replaced twice in 20,xxx miles and now needs to be replaced again.
