Engine complaints
P0306 misfire. Flashing check engine light. Ive replaced all spark plugs. Ive replaced the ignition coil. Still has not fixed problem. While doing research on how to replace fuel injectors came across an article stating special coverage N102291660 for fuel injectors extending the warranty to 10 years, 150,000 miles but this is not showing for my VIN. My vehicle has the 6.2L engine so Im not sure what this is covered for some but not others when this is a known problem. I bought this vehicle a year ago...

because my wife and I took in custody of our 3 nieces all under age 2 thinking this would be a reliable vehicle. Id like to understand why my vehicle os not covered for this known issue, but others Cadillac ESVs are.
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 the vehicle to a safe destination where the mobile mechanic was able to check it out. Luckily, I was not going high speeds and the public road I was driving on was not busy so I was able to pull over safely upon the issue the start of the warning lamp flashing. The engine component failure would have been a much higher safety risk for myself and others if I was driving on a busy road or highway. I have spoke with both GM and Cadillac, they are aware of this defect, yet refuse to provide relief. I have been quoted $13,000-$17,000 to begin repairs to the engine.
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 Cadillac dealership. The vehicle is available for inspection upon request.
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.
Lifters went out in January 2024 Paid thousands and thousands to repair and now having more issues again. Same issues the recalled 2021-2025 gym 6.2L have
With only 78k miles on my 2017 Escalade the same issue happened with the lifters like in the 2021-2025 models. We had to pay out 14k to replace the motor. GM has known about this problem for almost a decade and it's not fair that we had to pay out this much money to replace an engine with them knowing the problems. Had they told us years ago to change to a heavier oil or whatever we would have done so and maybe our factory engine would have lasted like so many previous year models up to 250k miles.
I am writing to formally report an unresolved issue involving a 2015 Cadillac Escalade that I purchased from a Toyota dealership less than one year ago. The vehicle has experienced a complete engine failure, and I am currently left with a non-drivable vehicle and a loan balance of approximately $30,000. Shortly after the engine failure, I took the vehicle to two different certified repair shops, one of which was a Cadillac service center. Both informed me that the engine is beyond repair and advised me to return...

the vehicle to the selling dealership due to the short time since purchase. I attempted to return to the Toyota dealership to seek a resolution or possibly trade in the vehicle. However, they informed me that the engine is now inoperable, and they declined to offer assistance. Despite repeated phone calls and emails requesting to speak with a manager, I have not received any response to date. I have also been informed that replacing the engine would cost approximately $17,000, while the current value of the vehicle is around $18,000. This puts me in an extremely difficult position - paying off a $30,000 loan on a vehicle that I cannot drive or repair affordably. The dealership arranged my financing and is fully aware of my financial obligations. I believe they should take some level of responsibility for selling me a vehicle that failed so quickly, especially given that I purchased it less than a year ago. I am seeking assistance from the DMV to help resolve this issue. I believe there may have been negligence or lack of proper disclosure at the time of sale, and I request a formal investigation into this matter. I am also open to mediation or any recommended steps to hold the dealership accountable and find a fair resolution. Please advise on the appropriate next steps or documentation you may need from me to proceed with this complaint. Thank you for your attention to this matter. I look forward to your response. Sincerely, [[redacted]] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
At 86,000 miles my 6.2 engine had to be rebuilt. Costing $14,000
Widely known problem with the 2017 Escalade motor with the active fuel management system. Driving in a very remote part of Wisconsin when engine light went on, indicating a lifter failure due to the afv shutting down cylinders. This is an extremly common problem with this engine/feature. I was left stranded with my family and a costly repair. (5k)
The engine is a 8 cylinder 6.2 liter. It starts out using 8 cylinders and progressively drops to 4 at highway speeds. The lifter failed, seized and gouged and ruined the block and camshaft. This preventable repair necessitated an entirely new engine. This happens to thousands of GM vehicles of a similar year, but GM only acknowledges years 2021-2024. They made a defective product, knew about it and refused to adress it

sudden loss of engine power while driving Risk of unexpected vehicle stalling in traffic Compromised engine performance and vehicle control Potential complete engine failure The manufacturer's service bulletin recognizes these systemic issues across multiple vehicle models, including my Escalade. Problem Confirmation: General Motors has explicitly documented the problem in Service Bulletin 15-06-01-002M, which covers 2015-2020 Cadillac Escalade models. This indicates a known, widespread manufacturing or design defect. Despite GM's explicit recognition of this critical engine defect, customers must pay for repairs out of pocket when the warranty expires. This places an undue financial burden on vehicle owners for a problem that is clearly a manufacturing defect.
Transmission failing. The transmission has had hard shifts and was serviced to try and fix this issue. No fix and now the transmission is slipping.
Cylinder 6 always presents as a misfired. Between my fiancé and I, we have 3 Escalades. After several diagnostic checks and repair bills, the lifters damaged the Cam shaft. According to the certified Cadillac mechanics, this is an ongoing problem based on the motor's design. This is a pretty costly repair x3 vehicles.
