“The engine malfunctioned. On October 19, 2026, the dealership advised by telephone that the engine would need to be replaced. The specific internal component or cause of failure has not been provided. The vehicle is available for inspection upon request. 1. During highway driving, the vehicle hesitated while accelerating and did not respond as expected. The driver backed off the accelerator and observed a flashing check-engine light. Unpredictable acceleration created concern about safely keeping pace with traffic. Additional noises and an unusual odor later developed. The vehicle was parked safely. 2. Yes. The dealership evaluated the reported problems and advised on October 19 that engine replacement was necessary. Written diagnostic findings have not yet been provided. 3. The dealership evaluated the vehicle. No separate inspection by the manufacturer, police, insurance representatives, or an independent service center is known. According to the records available to us, the vehicle was driven only TWO miles in connection with the dealership’s Certified Pre-Owned (CPO) inspection. This raises concern about whether the inspection adequately identified the…”

“6.2L Engine blew with less than 6,200 miles. Driving highway speed, started by hearing a slight tick and within 3 miles, the tick got louder, check engine light came on, then the pull over notice, pulled over and wouldn't start.

“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 (NHTSA 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…”

“Vehicle engine shutdown on routs [XXX] in [XXX] while traveling at 70mph.”

“I purchased a new 2026 Cadillac Escalade equipped with the 6.2L V8 engine and took delivery on XXX. At approximately 9,700 miles, the vehicle developed an engine-related problem and the check engine light illuminated. I brought the vehicle to Cadillac of Norwood in [XXX] on XXX During diagnosis, the dealership identified metal contamination in the engine oil. I was advised that, because metal was found in the oil, further internal diagnosis was stopped and the engine would need to be replaced. The dealership subsequently ordered a complete replacement engine. As of XXX, the vehicle remains at the dealership awaiting the replacement engine and has been out of service continuously since September 16. This is particularly concerning because the vehicle is approximately six months old and has fewer than 10,000 miles. An internal engine failure resulting in metal circulating in the oil at such low mileage raises concerns about premature engine failure and the possibility of loss of engine power if a similar failure occurs while the vehicle is being driven. Prior to this failure, I had also noticed an abnormal ticking noise from the engine. The vehicle has required…”
