2026 Cadillac Escalade problems

“The contact owns a 2026 Cadillac Escalade. The contact’s son stated that while coming to a stop, the engine unexpectedly seized. The contact stated that due to the failure, the vehicle could not be shifted into neutral. The contact’s son stated that a Police escort was required to prevent a crash. The Police issued a record to the contact’s son. The vehicle was towed to the dealer, where the engine failure was confirmed. The contact was informed that a diagnostic report would be provided later. The vehicle was not repaired. The manufacturer was made aware of the failure by telephone, and a case was opened. The contact was concerned that the failure was extremely dangerous while the contact’s son was operating the vehicle. The failure mileage was approximately 46,000.”

“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…”

“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…”

“I purchased a new 2026 Cadillac Escalade on July 27, 2026. Shortly after purchase, the vehicle began experiencing significant engine-related problems, including shaking, rough running, loss of power, knocking-type noises, misfires, and a check-engine light. The vehicle underwent three separate repair attempts for the engine-related concerns. During these visits, the dealer diagnosed and attempted to correct the misfire and related engine issues, including work involving the ignition coil/coil pack. Despite these repair attempts, the problems continued or returned. A fourth visit was then conducted as a final repair attempt. During this visit, a General Motors engineer became involved and attempted to diagnose and correct the vehicle’s continuing engine problems. Despite this additional manufacturer-level repair attempt, the underlying engine concern was not successfully resolved. The vehicle was essentially brand new when these problems began. After three repair attempts and a fourth final repair attempt involving a GM engineer, I remain concerned about the safety, reliability, and long-term condition of the engine because of the repeated shaking, loss of…”

“An over-the-air software update installed on my 2026 Cadillac Escalade IQ on September 11, 2026 removed the side-view camera display that previously appeared on the center infotainment screen whenever the turn signal was activated. Before the update, activating the right turn signal displayed a live video feed of the right side of the vehicle, which I relied on because the passenger-side exterior mirror provides a poor, narrow field of view (flat mirror with a bad angle, and no auto-dimming at night). After the update, no camera view appears and the mirror alone is inadequate, leaving the right-side blind spot completely unchecked when changing lanes or merging right. This safety-relevant feature worked correctly before the manufacturer's update and was disabled by it. I have also filed a safety complaint with Cadillac/GM customer assistance on September 12, 2026. No crash, injury, or property damage has occurred yet, but the vehicle is now meaningfully less safe to drive, and I request that NHTSA investigate this software change.”
