2024 Cadillac Escalade

I’m using this car in Poland (Europe) my engine starts to make knocking noise due to Bearings rods and lifters failure . N252494001 L87 Engine Loss of Propulsion I called to European Cadillac authorized service and they refused to replace the engine because USA based manufacturer don’t wan’t to repair a car even is still on warranty

After having the initial engine failure recall completed by the dealership by switching to a different viscosity oil… While traveling at 45 mph the motor made a knocking or ticking sound with a squeal and then “hiccuped “ and immediately lost all power. I was only able to steer the vehicle onto a busy sidestreet. The vehicle had recently been serviced by Cadillac. Once stopped, the vehicle cannot be shifted from park due to “shifting conditions not met” so I was blocking the entire intersection. Police had to respond for traffic control. Due to the electronic shifter the only way to shift the vehicle into neutral is with tools and getting underneath the vehicle to remove a bolt. There is no reasonable or prudent way to do this in the middle of an intersection.

Traveling on interstate preparing to exit on ramp. Press start button displayed, car immediately sounded like it geared down hard and then lost power, unable to control well, all I could do to come to a safe stop, while praying that the car behind me didn’t hit me. The car basically locked up while preparing to exit the interstate. So scary, terrifying and dangerous.

Component/System Involved: Engine / Powertrain and Vehicle Electronic Control Systems, including Serial Data Gateway Module Description of Failure: While driving at highway speed (approximately 60 mph), the vehicle experienced a sudden and complete loss of propulsion without warning. Engine power was lost while traveling on an interstate, forcing me to pull onto the shoulder without propulsion. The loss-of-power event occurred more than once during the same trip. The vehicle was towed to an authorized Cadillac dealership for inspection. Dealer diagnosis confirmed internal mechanical engine failure, including metal debris present in the engine oil, requiring full engine replacement. During diagnostic procedures, the dealership also identified electrical communication faults involving the serial data gateway module, including voltage fluctuation and wiring chafing within the vehicle harness. These faults caused loss-of-communication conditions between control modules and required repair. Safety Risk: The loss of propulsion occurred at highway speed with passengers present in the vehicle, creating a serious safety hazard. Sudden power loss on an interstate increased the risk of collision due to the inability to maintain speed or maneuver safely in traffic. Confirmation / Inspection: The failure was confirmed by an authorized Cadillac dealership. The engine was removed and replaced due to internal damage. Electrical communication faults related to the serial data gateway module were also confirmed and repaired. Warning Indicators: No warning lamps or alerts were displayed prior to the loss of propulsion. Communication faults were identified during post-failure diagnostics. Current Status: The vehicle has undergone engine replacement and electronic repairs and is currently under post-repair monitoring due to the severity and safety implications of the failure. Availability for Inspection: The vehicle and repair documentation should be available through dealership

The check engine light has been coming on intermittently and the engine has felt rough operating. On December 23, 2025, despite the absence of an illuminated "Check Engine Light", I was driving the vehicle when it suddenly lost power/acceleration in the middle of a busy street, which caused me to nearly get into an accident. I brought the vehicle into the Dealership on 12/29/25, and is still there as of 1/7/26. The Dealership has hooked my car up to the scanner, which found code P0300, and they indicated that it's showing a history of misfires across all cylinders. The Dealership has said that they cannot fix the car because they cannot get the Engine Light to illuminate and because as of 1/7/26, my VIN is not included in part of the widespread Engine recall. My vehicle poses an extreme safety risk to drive, and I do not feel comfortable driving it, knowing that the Engine is misfiring and could lose acceleration or power at any moment and without warning.

Vehicle: 2024 Cadillac EscaladenV VIN: [XXX] Mileage: ~31,000 miles On December 29, 2025 at approximately 7:30 a.m. Eastern Time, while driving at Approximately 30 mph under normal operating conditions, the front panoramic sunroof glass of my 2024 Cadillac Escalade V catastrophically shattered without warning. Ambient temperature was approximately 21°F. Weather conditions included freezing rain and high winds. The vehicle interior was heated. The interior sunshade was closed at the time of failure. The vehicle was equipped with a roof rack and a mounted cargo box positioned directly above the sunroof plane, providing physical shielding of the glass from above. There was no collision, no road debris strike, and no external object interaction. The glass failure was sudden and explosive. After safely pulling over and retracting the interior sunshade to assess the damage, glass fragments fell into the passenger compartment and struck both front occupants. Two children seated in the second row were not injured. Visual inspection shows no identifiable impact point, crater, or localized strike origin. Fracture patterns appear to originate near the perimeter of the glass panel, suggesting possible stress related or installation related failure rather than impact damage.

Engine failure. Started making a knocking noise on road with my whole family in the car, no lights or warnings on dash and had to pull over and get it towed to nearest dealer. Took a week to get a diagnostic done. Dealer found metal shavings in oil filter believe to be from a connecting rod bearing. Recall 252494000 was done 2,000 miles prior to engine failure. Now dealer must replace engine assembly, engine oil cooler and radiator all due to contamination

See attached document for complaint. I am writing to you as a deeply concerned mother and consumer seeking urgent help with a danger ous and unresolved engine defect in my 2024 Cadillac E calade, which has been formally recalled under NHT A Campaign 25V-274 (GM Recall 1 252494000). I purchased this vehicle in good faith, believing it would be a safe, reliable car to transport my three young children (age [XXX] , [XXX] , and [XXX] ). lnstead, the experience ha been frightening and exhau ting. The veh icle has suffered repeated engine issues, loss of power, and extended repair attempts - and despite the recall acknowledgment, there is till no available remedy or meaningful support from General Motors. For month , I ha e been unable to afely rely on the car 1 depend on every day. I have pent over a month col lectively without my vehicle and continue to live\ ith constant fear that the engine may fail while dri ing with my children in the car. Each time I tart the vehicle, 1 brace for the po sibi lity that it could suddenly lose propulsion in traffic i a terrifying thought for any parent. I have followed e ery step required under the, arranty and recall process, contacted the manufacturer, and recently issued a formal repurchase demand under California's ong-Beverly Con umer Warranty Act. GM has admitted the defect but continues to leave families like mine waiting indefinitely for a repair that doe not yet exi t. Tam pleading for your agency' immediate intervention and over ight to en ure that GM repurcha es my vehicle before tragedy strike . My family hould not be left driving an unsafe vehicle with known defects - especially when manufacturers had prior knowledge of these issues years before notifying the public. Plea e, I urge HTSA to reviev thi case and compel General Motors to take immediate, re ponsible action to resolve it. The fear and uncertainty this has caused are overwhelming. I should not have to choo e between my family' afety and my only mean of tran portation. Thank you for your time, attention, and
