CADILLAC Complaints

11/26/25 at 85,400 miles on the v8 6.2L L86 engine, I began experiencing rough idle, loss of engine power and propulsion, a ticking/ knocking noise at idle and when RPMs increased as well as blinking engine warning light. Diagnostics/Repair work was done by Reliable GMC/Cadillac of Roseville to fix an ignition coil that was giving the engine error code. 2/24/26 At 86,697 miles, I began having rough idle worse than before, loss of power when accelerating and driving, knocking sounds that increased with acceleration in RPMs as well as a blinking engine warning light. All spark plugs and wiring were changed by Cadillac which resolved engine error codes for misfire. Diagnostics/Repair was done by Reliable GMC/Cadillac of Roseville. 3/30/26 at 87,246 (only 549 miles since the previous work up,) the car began to idle rough, and have a audible rhythmic tapping and knocking when accelerating and increasing RPMs. During driving, I experienced flashing engine light, and then sudden loss of power and control of vehicle. 3/30/26 Veh towed toThompson GMC, of Placerville, CA diagnosed vehicle with full engine failure from broken connecting rods and crankshaft of engine. Dealership is recommending full engine replacement, costing approx $23,000. This engine failure occurred on XXX in [XXX] …a dangerous, steep and curvy 2 lane highway. The engine light and loud forceful knocking happened almost simultaneously, without warning. I was forced to perform a dangerous maneuver to exit the highway into a gas station. Had I not done so, the engine failure could have caused full control loss of the vehicle. Traveling approx 50-65mph with my wife, [XXX] son and 2 daughters, an engine failure put my entire family at risk of serious injury or death. Had I not acted quickly, the outcome would have been catastrophic if not fatal. The vehicle is currently at Thompson GMC, [XXX] and available for further inspection. We believe this may be related to NHTSA EA25007. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA)

Low beam headlights extremely dim. Feels like driving with parking lights only. Very difficult to see. While checking different positions of the headlight switch discovered that in the parking light position ALL lights go off.

While driving at approximately 40 MPH there was a loud pop and the panorama sunroof shattered. There were other cars traveling at the same speed or less, but nothing struck the vehicle to cause the glass to shatter. The glass did not immediately give way, but had it, there were passengers that would have been impacted. The roof was inspected by the dealership but is no longer available for inspection as the dealership could not provide a loaner or rental vehicle. There was no warning. The temperature was mild. This is not about the repair expense or time involved but about the safety or the panorama sunroof.

My original factory 2020 Escalade 6.2L engine suddenly without warning seized while driving on a two lane undivided highway. I was forced to steer and brake the vehicle from 70mph to the shoulder of the road. My Vehicle had to be towed to GM dealer who diagnosed a seized engine. GM Replaced engine under warranty. This incident is identical to the 6.2L engine failures of the 2021 to 2024 recall.

Driving on freeway, engine starting knocking loudly and completely failed. I blew an engine on my 2023 escalade esv as well. Seems like the recall might need to be extended to the 2026 models as well.

While driving at highway speeds, I needed to accelerate hard in order to pass another vehicle and while accelerating there was a downshift and increase in RPM. After passing, the RPM remained high even after I took foot off accelerator and it seemed the transmission did not shift back out of lower gear, keeping the car traveling at a high rate of speed, endangering myself and other traffic. Applying the brakes would not cause the engine to slow down and the engine kept working hard and traveling fast, causing strain on the brakes to slow down. I pulled over and initially shifted to neutral, but the engine was still revving high (4000 rpm observed). Then I placed the car in park which did not change the high RPM. Then I shut off engine and let it rest. Then I turned auto back on and all was normal. The problem has not yet been reported to dealer but will occur in coming days. There were no prior symptoms, problems, or warning lights on dash display prior to this occurring.

Rough running engine at idle. The vehicle also shows low oil pressure at idle 13psi. Took to several service technicians and was told this is unfortunately a flaw in the engine design and there is not a known current remedy. Also they are surprised that this model was not covered under the same recall campaign that later models are as they are nearly identical engines. The transmission also gave out on this same vehicle at 85k miles.

This is the second time the EV charging system has alerted for overheating and inability to charge. The dealer has now had the car for 2 weeks this second time. It was in the shop for 4 days the 1st time when the issue was not fixed. I was in the vehicle with my small child and had no air conditioning as well.

Transmission would intermittently lock up and cause rough running conditions. Occasionally causing wheels to lock up and the vehicle to lose control. Took the vehicle to multiple service facilities and was told this is a common issue with this transmission and it is in need of replacement to remedy the issue. The vehicle has 85,000 miles on it.

The original engine was replaced in my Escalade in September 2025 under the GM Engine Recall. The original engine was working, but it failed the inspection at the dealership and was replaced. March 1st, 2026 the Escalade died while driving. Police came and helped block traffic and called a tow truck since the engine was dead. The Escalade was towed back to the same dealership and they confirmed the newly replaced engine failed under the same bulletin that mandated the replacement of the original engine.
