While driving at highway speeds of approximately 65 mph, the vehicle suddenly suffered a catastrophic loss of propulsion/motive power in active traffic. The engine oil temperature surged, and the vehicle completely lost power, forcing me to navigate across lanes to the shoulder without engine power, creating an immediate, severe safety hazard of a high-speed rear-end collision. The vehicle had to be towed via flatbed. This vehicle previously had an open recall for this exact issue under the federal safety agency Recall 25V‑274. The GM dealership closed the recall on September 2025. by applying the authorized remedy: replacing the engine oil with 0W-40 and installing a new oil fill cap. No component replacement was performed because the dealer stated it passed inspection.

What 2023 Cadillac Escalade ESV owners say
Most recent owner complaints, unedited.
engine seized on the highway
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 diagnosis delayed meaningful investigation. GM escalated the matter to a specialized field engineer at Braman Cadillac. I was informed that the senior engineer could not identify the cause and requested another engineer. The promised follow-up inspection was still pending nearly three weeks later. Despite repeated visits and manufacturer involvement, no confirmed root cause or permanent repair has been provided. GM did not arrange towing for the latest return. I drove the malfunctioning vehicle in the emergency lane everyt time because it could not be trusted to maintain normal operation. The vehicle remains at the dealership and is available for inspection. I request investigation of the recurring shutdown/loss-of-propulsion safety defect and the unsuccessful diagnostic and repair history.
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 separate, documented engine, brake, and electrical-system safety concerns. Dealer repair records and supporting video footage are available for review.
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 the federal safety agency investigate this pattern of defective replacement engines and faulty dealership repairs to prevent severe safety hazards on public roads. p.s. I have all email communications and video recordings of this issue.
My 2023 Cadillac Escalade ESV, equipped with the 6.2L V8 engine, developed an abnormal engine knocking/clicking noise despite previously receiving the remedy for GM engine safety recall N252494000, the federal safety agency campaign 25V274. On August 21, 2025, at 37,437 miles, Costa Mesa GMC Cadillac performed the recall inspection. The repair invoice states that the engine passed the PicoScope inspection and that the dealer changed the oil and filter and installed a new oil-fill cap. On September 16, 2026, at approximately 49,000 miles, I first noticed an unusual engine noise while driving through a store parking lot. After returning home, I observed a clicking/knocking noise at approximately 1,500–2,000 RPM. On September 17, I brought the vehicle to Costa Mesa GMC Cadillac at 49,093 miles. Repair order 61438 documents an engine knock during acceleration. Approximately two hours after drop-off, the service adviser informed me that GM had authorized replacement of the engine. As of September 24, 2026, the vehicle has remained at the dealership for one week and is awaiting a replacement engine. The vehicle is available at the dealership for inspection, subject to coordination with the dealer. Whether the original engine will be retained and available for inspection after replacement is UNKNOWN. My safety concern is the potential for engine failure and sudden loss of propulsion while driving, which could increase the risk of a collision. The recall notice specifically identified this risk. I am reporting the abnormal engine noise and dealer-reported need for replacement; whether the engine had reached the point of imminent seizure or loss of propulsion is UNKNOWN. The dealer evaluated the vehicle and reported GM’s replacement authorization. The exact internal component failure and root cause are UNKNOWN because I have not received the final diagnostic or repair report. Whether a GM representative separately inspected the engine, rather than reviewing the dealer’s findings, is UNKNOW
