2015 Cadillac Escalade transmission problems

Filed Sep 29, 2026 · Acceleration, Transmission · TX

While I was driving i needed to accelerate to pass slower traffic. As I pressed the accelerator I I felt a shudder and binding sensation throughout the vehicle and had to make a very drastic and unplanned maneuver to return to my lane as I had not completely departed from my lane, while maneuvering back in my lane I was forced to make several decisions as what next to do not know how my vehicle was going to respond to further acceleration attempts and if my wheels were going to lock up going freeway speeds. Since the incident I have noticed when my transmission fluid temp reaches between 100° and 150° my truck consistently exhibits the same behaviors inconsistent acceleration, clunking sounds, grinding/ binding sensation felt while at highway cruising speeds, clunk sounds during deceleration under breaking. I purchased the vehicle on 9/10/26 used. I have since stopped using this vehicle because it is a primary family vehicle used for schools drop off and pick ups as well as traveling for sports events. I do not trust that the behavior of the truck will simply works itself out and I will not risk my family safety on the roadway. Also after driving my vehicle the transmission fluid temp reading does not go down to ambient temperatures after 8 hours of setting.

My 2015 Cadillac Escalade 6.2L V8 with Active Fuel Management has had repeated lifter/valvetrain failures. On 10/2/2025 at approximately 109,536 miles, an independent repair shop confirmed a failed lifter on cylinder 3. The driver-side cylinder head was removed and all eight lifters on that bank were replaced along with a pushrod. On 9/9/2026 at approximately 116,689 miles, only about 7,153 miles later, the vehicle again developed severe shaking while driving. A different independent repair shop documented diagnostic code P0300, cylinder 1 low compression and misfiring, and noted that the lifters on that side had recently been replaced. Additional lifter-related parts, including lifters, a pushrod, guide and VLOM plate, were replaced. The shaking and misfire occurred while the vehicle was being driven, which concerned me because a sudden engine misfire or loss of normal engine performance could reduce power and affect safe control of the vehicle in traffic. Both failures were confirmed and repaired by independent automotive repair facilities. After the most recent repair, I returned the vehicle to the mechanic because it still felt different and had some vibration. The mechanic stated that the engine currently checks out, but I can still feel vibration that was not present before these problems. I do not know whether the removed failed lifter components are still available for inspection, but I have repair invoices documenting both failures and repairs. To my knowledge, the lifter failures themselves have not been inspected by General Motors, police, or an insurance representative. The second failure was documented with code P0300, low compression and a cylinder 1 misfire. I do not know whether the check-engine warning lamp was illuminated at the exact time the symptoms first began.

The contact owns a 2015 Cadillac Escalade. The contact stated that while driving through a conveyor car wash with child occupants in the rear seats, the vehicle was placed in neutral (N). The vehicle was then shifted into drive (D) as instructed but accelerated independently. The contact added that the vehicle barely made a left turn exiting the car wash bay, nearly colliding with a wall and a car wash door. The contact depressed the brake pedal, but the vehicle failed to slow down. The contact shifted the vehicle into park (P), but the vehicle failed to stop. The contact added that after shifting the vehicle into neutral (N), a roaring noise emanated from the engine compartment as if the vehicle continued to accelerate. The contact depressed the power button, but the vehicle failed to shut off. The vehicle continued across the parking lot at a high rate of speed. The contact made a sharp right turn, nearly missing the car wash stalls, and then shifted the gear selector between park (P) and neutral (N) quickly multiple times. The vehicle accelerated in a circle, slowed down, came to an abrupt stop, and rocked violently before turning off. The contact then noticed a clicking noise behind the dashboard, and unknown warning lights, numbers, and messages appeared. The son-in-law of the contact arrived and restarted the vehicle. A police report was filed. The contact sustained a sore neck, and the child occupants became dizzy, but medical attention was not provided. The vehicle was towed to a dealer where the failure could not be replicated. The vehicle was left at the dealer. The manufacturer was notified of the failure. The failure mileage was approximately 130,000.

Mileage: 90,406 2015 Cadillac Escalade Engine: 6.2L V8 EcoTec3 has experienced lifter and camshaft failure, and the vehicle is now stalling while driving, creating a serious safety risk. I transport my disabled child daily, and the stalls are unpredictable, putting us and other drivers at risk. This issue is consistent with the pending class action Harrison v. General Motors LLC, which alleges that 2014–present Cadillac Escalades with 6.2L AFM/DFM lifters can fail, causing engine noise, stalling, and catastrophic engine failure. The vehicle was service on 3/02/2026 at Riverview Chevrolet GMC for these issues and a complaint was summit to GM for these problems. Since after having the vehicles services I have had issues with the vehicle stalling while in progress and while driving causing me to be very scary that the vehicle will completely stall out or shut down on me while on the road driving causing an accident. Please help me resolve this unsafe matter. Thank You!

Vehicle has a shake that seems to be coming from the rear and can be felt in the seats, slightly in the steering wheel while driving at highway speeds ( 70+ ) this shake or vibration come in waves but never goes away long as you are traveling at highway speeds . It goes from an annoying shake to a bad shake and from a bad shake to annoying shake if that makes sense . I’ve spoken with different mechanics including the GM dealer and no one seems to have a fix just recommendation of expense part replacements that hasn’t worked for other Escalade owner with the same issue . I have experienced hard shifting from park to reverse and from 1st gear to 2nd but a temp sensor replacement seemed to have resolved the harsh shifting some what. It’s not as bad but still feel a gear thud when shifting after a cold start but not so much after it’s been driven for awhile. My main concern is the shaking . It’s an embarrassing ride with passengers to the point I avoid driving it on long trips For fear that my Escalade will break down completely leaving myself and family stranded. I’m not looking for free handout repairs I just want to be pointed in the right direction of a sure fire resolution so I can get it repaired and start enjoying my vehicle .

I dropped my vehicle off for transmission service maintenance with no engine issues and no check engine light. The Cadillac dealer called me the next day and said the check engine light was on and the engine was bad and needed $12,000 repair due to faulty bad designed lifter's and camshaft also stated this is a well know defect in the engine and they have replaced many 6.2 engines. Vehicle has 59,345 miles and has a 72,000 mile powertrain warranty. I contacted GM and was told no they would not help with the cost. I drove the vehicle home and it would stall out at stop lights the stabilitrack and ABS lights came on and it would not go over 35MPH. Vehicle is dangerous to drive.

Transmission brakes at speed, feels as if I got rear ended from the back. I know that there is lawsuits against GM for this same problem that I am having. GM knew about these transmission problems and told everyone that this 8 speed transmission was supposed to shift this way. But, now I have it parked in my driveway. Is there anyway that I can get my truck fixed?
