2023 Cadillac Escalade engine problems

“After the recall and switching to the new oil viscosity, the 6.2 ltr engine still quit working! Dealership said bearings seized up and metal shavings were found in the oil.”

“Since May 24, 2026, my 2023 Cadillac Escalade ESV has repeatedly experienced reduced engine power, check-engine warnings, multiple dashboard alerts and loss of propulsion. During one incident, the motor stopped responding, the vehicle lost power and came to a complete stop in the middle of a public roadway. This exposed me and surrounding motorists to a serious collision risk. Whether the shutdown resulted from an internal engine failure or an electrical/control-system malfunction remains UNKNOWN. OnStar documented recurring warnings and fault codes, including engine/transmission communication faults. The same condition returned after multiple dealership visits and repair attempts, including module resets/reprogramming. At times the check-engine light was no longer illuminated upon arrival, but the dangerous symptoms and OnStar reports had already occurred. An authorized Cadillac dealership blamed alleged aftermarket alarm/tracking equipment and proposed charging approximately $1,900 to remove it. I paid $250 for an independent inspection, which found no such aftermarket equipment and identified the questioned component as a genuine GM part. This incorrect…”

“I am reporting a catastrophic engine failure on my 2023 Cadillac Escalade with the 6.2L L87 V8 engine (currently at 106,000 miles). The engine suffered sudden engine failure while driving / stalling, creating an immediate traffic hazard. The vehicle was towed to an authorized Cadillac dealership in Louisiana, where it has remained completely unrepaired for 60 consecutive days. The dealership claims they cannot repair the safety defect because they are "short-staffed." This vehicle’s failure directly matches the systemic manufacturing defects currently under investigation by the Office of Defects Investigation in Engineering Analysis EA26005. The manufacturer's inability to provide a timely repair through its dealer network leaves a known safety hazard unresolved.”

“Around May 2025; we noticed a ticking/knocking noise coming from our engine. We popped the hood, confirmed the noise was coming from somewhere in the engine. Shut the vehicle off, noticed that the drive belt was significantly damaged/frayed. Brought it to the dealership - they we were informed that our engine had failed related to the GM 2025 recall. Engine was replaced at 68,500 miles with new engine. October 2026, around approximately 103,000 miles, we heard the same ticking/knocking noise coming from the engine. Again, popped the hood & found the drive belt to once again be destroyed, this time even worse from our perspective. Cracked in several places, frayed edges along several sections. Had the vehicle towed back to the same dealership the following day (Monday). Service advisor let us know the next day that the engine had "internal failure." Per the technician, "crankshaft bearing failure - premature wear, oil pressure collapse, and destruction of the main and rod bearings."”

“On September 24, 2024, my 2023 Cadillac Escalade ESV stalled while I was driving in traffic and would not restart. I was unable to proceed normally at a green light, creating a risk of a rear-end or other collision. I have video footage of the vehicle unable to proceed. The authorized dealership documented a no-crank/no-start condition and found the engine assembly was seized. The engine assembly was replaced under warranty. Following the September 24 engine failure, the vehicle remained at the dealership through October 31, 2024 while the engine assembly was replaced under warranty. Earlier that same day, the dealership completed serial-data gateway module reprogramming and brake-system control-module programming related to brake-fluid leak detection. This is included as a factual chronology; I do not know whether that work was related to the engine seizure. Separately, on July 30, 2024, I received a “Replace Brake Pads” warning and heard grinding. The dealer found the driver-side front brake pads metal-on-metal and the wear sensor damaged. The dealer replaced the front brake pads, rotors, and wear sensor, and performed a brake-fluid exchange. These are…”

“I am filing this safety complaint regarding a critical, unresolved mechanical defect in my 2023 Cadillac Escalade ESV (approx. 80,000 miles). The dealership (Earnhardt Chandler Cadillac) notified me that my vehicle required an engine replacement under a recall/warranty service. Following their service, a brand-new replacement engine was installed. However, immediately after the replacement, the new engine developed a loud metallic knock upon cold starts, indicating severe internal mechanical failure, defective components, or improper assembly. Despite recognizing this critical defect, the dealership and General Motors failed to rectify it. Most dangerously, they recently delivered the vehicle back to my residence, claiming it was "fine," while the engine continues to exhibit the exact same loud metallic knocking noise. Operating a vehicle with a severely defective, knocking replacement engine poses a high risk of catastrophic engine failure, sudden loss of power while driving, and potential highway accidents, endangering my safety and the safety of other motorists. I request that NHTSA investigate this pattern of defective replacement engines and faulty…”
