Engine knocking on cold start up. Second time hearing this. Loud “rattling” noise emanating from exhaust tips on rear of vehicle. I experienced this once before and notified my dealer. Additionally, at that time, I had a loss of power while towing a very, very, light empty trailer. The vehicle was struggling to maintain normal driving speeds and required considerable throttle input to do so. The loss of power was so pronounced that I actually pulled over to the side of the road in a parking lot to check to see if the wheel bearings had locked up on the small trailer I was towing. Of course, the trailer was completely normal and the hub temperatures were completely normal. I later found out about the GM L87 Engine issues and the recall issue. This vehicle then had the “pico“ test performed on it, and I was informed that it had passed. However, today I once again heard the same engine knock that I heard a few months ago.

Subject: Safety Complaint – 2022 Cadillac Escalade ESV Transmission Failure After Recall Repair To Whom It May Concern, I am submitting a formal safety complaint regarding my 2022 Cadillac Escalade ESV. VIN: [XXX] My vehicle experienced a serious transmission malfunction where the vehicle would not properly engage in reverse. The “R” gear indicator blinked multiple times, and the vehicle became unsafe and unreliable to operate. Cadillac dealership diagnostics later confirmed issues related to the transmission valve body and/or transmission control components. After researching this issue, I discovered that GM and NHTSA issued Recall No. 26V085000 regarding transmission control valve body wear in certain 2022 Cadillac Escalade vehicles equipped with the 10-speed transmission. The major concern is that my vehicle had already received the recall/software update before this failure occurred. Despite completing the recall remedy, the exact transmission problem still happened. I never received any warning before the failure. I was forced to spend significant time and money dealing with towing, dealership visits, diagnostics, and transportation disruption for my family. This raises serious concerns that the recall software update does not actually resolve the underlying mechanical defect within the transmission valve body. For a luxury SUV of this value and age, this type of major transmission failure is unacceptable and creates a serious safety concern. I request a full investigation into why the recall remedy failed, confirmation of all recall work completed on my VIN, and extended warranty coverage for the transmission and related drivetrain components. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I own a 2022 Cadillac Escalade equipped with the 6.2L V8 engine. While driving in [XXX] near [XXX] and XXX [XXX] , the engine suddenly failed without warning and left me stranded in traffic. Prior to the failure, there were either no warning signs or insufficient warning indicators to safely prevent the incident. The sudden engine failure created a serious safety concern because the vehicle lost power while operating on a public roadway. I was forced to pull over unexpectedly in traffic conditions, placing myself and others at risk. The vehicle had to be towed and I was informed the engine would require major repair or replacement. I have since learned that other owners of GM vehicles equipped with the 6.2L engine have reported similar catastrophic engine failures. The failure appears to occur unexpectedly and can leave drivers stranded without adequate warning. I believe this issue represents a significant safety risk and should be investigated.

On February 21, 2026, my 2022 Cadillac Escalade ESV experienced a sudden and complete engine seizure at highway speed at 57,825 miles just 8,613 miles after passing GM's PicoScope inspection under Safety Recall N252494000 (NHTSA Campaign 25V274). After fueling, I entered a highway on-ramp and accelerated to approximately 70 mph. Within 30 seconds, the engine lost power completely with no prior warning lights, no diagnostic trouble codes, and no audible warning. The only dashboard notification was a prompt to press the Start button. The vehicle behaved as if shifted into neutral, decelerating rapidly from 70 mph to 40 mph while I was navigating an exit merge ramp. I reached the right shoulder safely. Under normal weekday traffic, this failure on an active merge ramp could have caused a serious collision. The engine would not restart. The vehicle would not shift out of Park. OnStar could not remotely start the vehicle. A tow truck was dispatched; the operator could not shift the vehicle to neutral and required a dolly. The dealership confirmed the engine had seized and the engine would not crank. A complete engine replacement was performed under the recall warranty (RO 606490). The recall remedy was performed August 20, 2025 at 49,212 miles. GM records confirm the PicoScope result: "Engine Passed." The engine seized 8,613 miles later with no warning. This is consistent with 30-plus NHTSA complaints reporting loss of propulsion after the prior remedy, and demonstrates the inspection-based remedy is insufficient to identify engines at imminent risk of seizure.

My 2022 Cadillac Escalade Diesel (3.0 LM2) is experiencing a failure of the engine coolant control valve, a known defect addressed by GM under Special Coverage bulletin N252508341. The failure causes: •Intermittent reduced engine power •High-speed radiator cooling fans running continuously •Check engine light •Emissions system malfunction As a result of this condition, the vehicle fails emissions/smog testing and cannot be registered or legally operated in my state when the fault is active. The reduced power condition occurs unpredictably during normal driving, creating a drivability and safety concern, especially during merging, highway driving, and traffic conditions. GM has acknowledged the defect through a Special Coverage program but has denied repair coverage due to salvage title branding, leaving the vehicle with an unresolved emissions-related defect that affects safe operation and compliance. This issue is unrelated to any prior damage and occurs during normal vehicle operation.

At approximately 6:45pm on Friday November 14, 2025, while driving among tractor trailers in the passing lane at highway speed on westbound RT 30 near mile marker 191 (Lancaster, PA), my 2022 Cadillac Escalade ESV Sport Platinum experienced a complete loss of propulsion. This catastrophic and sudden engine shutdown came with no warning lights, no symptoms prior to a complete loss of power. The vehicle had previously been inspected as part of the recall service by Fred Beans Cadillac in Doylestown months prior and customer was informed it had passed the recall inspection and was given the recommended corrective action - (new oil [0W40], oil filler cap and new oil filter). Customer had ABSOLUTELY NO REASON TO SUSPECT this engine had issues, because it "passed" GM's recall... This vehicle's unexpected & compete loss of power gravely endangered the lives of the vehicle's four occupants who were absolutely terrified during this experience ! I put the vehicle's hazard lights on and guided it to a stop on the right shoulder of RT 30 at the mile marker 191 Westbound. I contacted my insurance provider's roadside assistance for a flatbed tow off the highway. Vehicle was eventually flatbed to Kelly Cadillac for engine diagnosis. [will give much more details in subsequent communications as the characters here are limited] We are awaiting Cadillac dealer's diagnosis of the cause of this catastrophic engine failure with complete loss of propulsion at highway speed (after the recall was performed and vehicle was cleared). I have added photos of the confirmation from the insurance company's dispatch of a flatbed to my location on RT 30 as well as a screenshot of us on the right shoulder of RT 30. I have attached text messages received from GM of the engine issue that were received AFTER the vehicle was stopped on the shoulder of highway. My family - and others on the highway that evening - could have been gravely injured or even killed by this Cadillac's complete malfunction !

Complete engine failure with no prior warning and vehicle is currently at dealer waiting for new engine to arrive. The lives of myself and my children were at risk as the engine failure occurred while traveling at about 55 mph on a rural country road with cars having to swerve around me before I came to a complete stop on the shoulder of road. Again there was no prior warning or warning lights on the vehicle. The Cadillac dealership in Texarkana has inspected the vehicle and determined the engine failed and needs a completely new engine.

On April 24, 2025, GM issued recall 25V-274 to address the concern with L87 engines produced between March 1, 2021, and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issues. GM’s recall remedy will be either an oil change to an oil with a different viscosity or engine replacement depending on the results of the remedy inspection procedure.
