The vehicle has experienced premature factory paint and clear coat delamination across the main roof panel structure. This is not cosmetic weathering; it is a latent factory application defect where the clear coat chemically failed to bond to the substrate. The resulting delamination has left raw structural metal exposed, leading to rapid substrate oxidation and structural degradation of the roof panel sheet metal. The advanced delamination and corrosion have directly compromised the sealing integrity of the roof-mounted GPS/emergency communication antenna and the structural integrity of the roof rack mounting tracks. Water intrusion through the compromised factory finish risks shorting out emergency telematics, causing electrical fires in the headliner, or causing a structural failure of aftermarket cargo crossbars at highway speeds, creating a severe road hazard for vehicles traveling behind me. This is a known, widespread manufacturing flaw originating from the Arlington Assembly...

Engine misfire, AFM lifter collapse, defective AFM/DOD lifter technology. The three diagnosis I have had done to check for multiple opinions have all come back the same with a collapsed AFM lifter causing camshaft damage, overall failure of an AFM/DOD deactiviating lifter in the 6.2L L86 engine leading to engine damage. It is available for inspection. The problem has been confirmed by multiple independent service providers and confirmed to be an issue in ongoing litigation against GM. It was initially diagnosed by a mobile mechanic and then taken to a independent service mechanic who confirmed the initial diagnosis. It was then confirmed again by a third party independent mechanic. The engine light did not appear until the noise started and what I now know as when the lifters failed, at which after my vehicle alerted me with the engine light. When the problem first occurred, I was driving around 35 MPH down a public road, I had to immediately slow down and pull over. I then limped...

My 2017 Cadillac Escalade with the 6.2L V8 engine experienced AFM (Active Fuel Management) valve lifter failure. While driving on the freeway the vehicle began stuttering and shaking violently, and it felt as though I had lost control of the vehicle. The check engine light illuminated and diagnostic codes P0300 (random misfire) and P0304 (cylinder 4 misfire) were found. The vehicle was confirmed by a Cadillac dealership to have collapsed AFM lifters on the right side, a faulty valve lifter oil manifold (VLOM), and a broken exhaust bolt requiring extraction. The engine was also showing slightly low compression at times and making noise on cylinder 4. This is a known defect in GM's AFM system across multiple model years. The failure poses a serious safety risk as the stuttering, shaking, and sudden loss of engine power occurred unexpectedly at freeway speeds, significantly reducing my ability to safely control the vehicle. The repair has been confirmed and quoted by an authorized Cadilla...

The 6.2 L engine on my 2017 Cadillac Escalade failed at around 97,000 miles. I took it to Heritage Cadillac dealership for a diagnostic check and had it repaired. The engine had a broken engine rod and lifters damage to the engine. I had the engine repaired at the dealership but a few weeks later I heard rattling noise coming from the engine. I took it back and told I would need a another engine due to complete engine failure. Prior to my engine failure around 55,000 miles, I reported to the same dealership service department that I noticed the engine would give me a rough idle occasionally and burn more gas whenever it happened. I was told it was nothing they could do because the check engine light wasn't on.
