2015 Cadillac Escalade electrical problems

Filed Sep 17, 2026 · Electrical, Engine · RI

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.

THIS IS FOR SAFETY RECALL IN oct 2019- regarding the brakes- it has ALREADY BEEN MADE AWARE TO DOT. This is in regards to getting a refund for my almost 4k out of pocket expense. The brakes went out completely in sept 2019 ( in 5-7 mph I could not stop in traffic even with them all the way pushed to the floor. and caused a front end collision ad the brakes been working normally this would have never happened. I was wondering what i needed to do ( or if i can ) to get reimbursed for the damages that i incurred on fixing my vehicle. ( around 4,000). Or if i need to notify Cadillac of this issue. Also the vehicle went in for repairs after the recall was issued ( we were never told or advised by the dealer that there was a recall open) and have no idea why the dealer would not even tell us, or advise us of such.

I have a 2015 Cadillac Escalade. It has been well taken care of. To my disappointment, this vehicle has been a money pit since day one. We have had to have all shocks replaced two times since January 16, 2020, costing thousands of dollars.The front cross bar was replaced the first time the shocks were replaced. The airconditioning system went out in the summer of 2020, replacement cost over 2500.00 The back suspension was just replaced in December 2022 for 2100.00. Running board motor wore out. Radio touch screen had to be replaced because it did not respond to tounch 1400.00 No warning lights appeared. SAFETY ISSUES**** The automatic seatbelt system no longer works since August 2022. Now the side detection system doesn't work since December 2022, replacement cost will be 1500.00 These have both been inspected by a dealer. These put myself, my passengers, and others at risk by not properly ensuring their safety while in my car and drivers in my blind spot. I do not feel safe driving this vehicle any longer. I don't know when or where it will malfunction next and that will extremely dangerous to those in my car and driving along side me. Needless to say, this vehicle has cost us more money than the beauty of the vehicle. These are a just a few of the issues we have encountered while owning it and I can honestly say, we will probably not purchase another Cadallic again.

My vehicle stops running when I am placing it in reverse or making slow turns. The car turns off and the driver assist screen turns off (cameras do not work) and then my car says 'service: driver assist'. I have been driving at a low rate of speed on the street and my car stops running and the steering wheel becomes very tight and hard to turn. When I am backing into a parking space, my steering wheel is hard to turn and the car shuts off and the screen that shows my cameras goes out and then the car comes back on. It is very scary. I am very afraid that the car will stop running while in motion again and cause an accident. I have contacted onstar about this and requested roadside assistance, it was the weekend and they would not send them. The car turning off has occurred more than 7 times in the past month. It started in april 2020.
