Cadillac Escalade ESV loss of power problems

Filed Nov 8, 2026 · Engine · NV

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.

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 Friday, XXX, my 2026 Cadillac Escalade ESV (VIN: [XXX]), with approximately 10,000 miles, experienced a sudden and complete engine failure while I was driving on a busy highway exit ramp. My wife, [XXX] daughter, and dog were in the vehicle. The engine died without warning, resulting in total loss of power. We were extremely fortunate that no following vehicle struck us. This created an immediate and serious risk of a high-speed collision. The vehicle was towed to Pepe Cadillac of [XXX]. Pepe Cadillac diagnosed the failure as involving metal shavings/contamination in the oil, internal engine failure consistent with spun bearing and/or crankshaft/connecting rod issues, and stated that it matches the known L87 6.2-liter V8 manufacturing defect. A complete engine replacement is required. The vehicle remains at the dealership waiting on a new engine. This failure pattern matches the manufacturing defects that were the subject of the prior safety recall on 2021–2024 L87 engines (the federal safety agency 25V274000) and that are currently under investigation in Engineering Analysis EA26005, which covers 2021–2026 model year vehicles including the Escalade and Escalade ESV. I am submitting this complaint so that it can be added to the open investigation. Sudden loss of propulsion while driving is a clear safety defect.

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.

On Sunday, September 6, 2026, at approximately 10:38am, my wife was driving our 2026 Cadillac Escalade ESV Platinum Sport (VIN 1GYS9RKL8TR113098, ~9,000 miles) with multiple young children in the vehicle. The vehicle began making loud clicking noises and lost power at a busy intersection, with no prior warning lights or messages; the clicking was the only symptom before the sudden loss of power. She maneuvered it partially off the road; it would not restart. She removed the children onto the roadside while managing a disabled vehicle in active traffic, creating real risk of a secondary collision. I arrived at 11:00am and tried to restart it, including adding fuel, with no success, only intermittent clicking and no start. A jump start was attempted before AAA arrived. AAA arrived at 1:16pm, inspected the vehicle, and confirmed the battery and fuse boxes were fine and not the cause. OnStar was also contacted. The vehicle was towed at 2:37pm to Camargo Cadillac, our dealer. I contacted the dealership the next morning. On September 9, their service department confirmed the engine had failed internally and requires full replacement, a diagnosis made by the authorized dealer, not merely suspected by me. The failed engine remains at the dealership, unremoved, and is available for inspection upon request. I've opened Case #SR:110162786 with Cadillac Customer Assistance; I am not aware of a direct GM factory-level inspection yet. At approximately 9,000 miles and roughly nine months of ownership, this vehicle suffered a total, sudden engine failure with no advance warning, stranding my family in traffic. This engine (L87, 6.2L V8) is subject to a prior recall (25V‑274) on 2021-2024 Escalades for related crankshaft and connecting rod defects, and the federal safety agency has since opened investigation EA26005, extending to 2025 and 2026 model year vehicles due to continued reported failures. I'm submitting this to add my vehicle's experience to that federal safety record.

Vehicle: 2019 Cadillac Escalade ESV VIN: [XXX] Engine: 6.2L V8 L86 Mileage: Less than 59,000 miles I am reporting a serious premature engine failure involving the 6.2L L86 engine in my 2019 Cadillac Escalade ESV. The vehicle has been properly maintained with regular oil changes and routine service. On September 8, 2026, the vehicle developed a chirping sound during startup. After driving, the chirping stopped, but a ticking noise occurred when the vehicle was restarted. I immediately had the vehicle evaluated by an independent mechanic. The mechanic kept the vehicle for two nights so that a cold-start evaluation could be performed. On September 10, I was informed that the engine noise was caused by lifter failure. The vehicle was then towed to a Cadillac dealership in [XXX]. On XXX, the Cadillac dealership diagnosed lifter failure and camshaft damage. The vehicle had not experienced a loss of oil pressure, noticeable loss of power, hesitation, or other significant warning symptoms before the failure. I am concerned because General Motors has issued technical service bulletins addressing lifter failures and ticking noises involving the 6.2L L86 engine and the Cadillac Escalade, including GM bulletin 15-06-01-002 and GM bulletin 19-NA-218. The vehicle has less than 59,000 miles. I am requesting that the federal safety agency document this engine failure and review whether similar failures involving this engine and vehicle warrant further investigation or action.

On XXX, at approximately 6:30 AM, I was driving my Cadillac Escalade ESV when the vehicle suddenly and completely lost engine power while I was traveling on the roadway. The engine stopped without any warning.There were no warning lights, warning messages, unusual noises, or other indications that an engine failure was about to occur. The loss of propulsion was sudden and unexpected.I was barely able to maneuver approximately half of the vehicle onto the shoulder. A significant portion of the vehicle remained in the roadway, creating a serious safety hazard to me and other motorists. I was forced to remain in this dangerous position for approximately two hours while waiting for a tow truck.The vehicle was towed to Richland Motors in Roswell, New Mexico. The dealership diagnosed the engine as seized and determined that the engine requires replacement. I have been informed that a replacement engine is currently unavailable/on backorder, and I have not been provided with a definite date when the vehicle will be repaired.This incident is particularly concerning because the vehicle had already received the L87 engine recall repair at the dealership on XXX. The recall repair was completed approximately five months before this catastrophic engine failure. As part of the service performed at that time, the engine oil was changed to 0W-40.The vehicle subsequently experienced a complete engine failure and sudden loss of propulsion while being driven, despite having already undergone the recall repair. The most significant safety concern is the sudden loss of propulsion without any warning. There was no opportunity for me to recognize an impending engine failure and safely pull off the roadway before the engine stopped. I was fortunate to be able to get part of the vehicle onto the shoulder, but the vehicle remained partially in the roadway for approximately two hours while awaiting assistance.am requesting that the federal safety agency document and investigate this.
