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.

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.

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.

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.
