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

While driving vehicle reported multiple system failures and started shaking. Was safety parked and towed to dealership. Dealership found metal shavings in engine oil. No resolution as of yet.

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 tires were swaying

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

Having it at four different dealers have not corrected the infotainment screen, adaptive cruise control phantom braking, electrical display issues such as ambient temperature, malfunctioning fuel gauge. Check engine notification was on, they seem to have corrected that, the next notification was service rear axle. Back up camera fails intermittently. I have had it to the dealer nine times, GM won't do a buy back I guess until they are sued. Also, dealer changed the oil to a thicker viscosity due to the engine recall. All the above ongoing for a full year.

Clicking that the dealer stated was normal. It was not loud knocking saying that is how the high flow fuel pump worked. Safety braking did not work at all. And there was a water intrusion in the trunk.

The brake system failed within 3 months of purchase of Cadillac Escalade. The mileage was 4,209 miles, when the incident occurred The vehicle was towed to Massey Cadillac, Authorised Service Partner (ASP) and diagnosed that 'DIAG BRAKE LIGHT C058A BREAK MASTER CYLINDER HAS INTERNAL FAULT'. They replaced the faulty part and the brake is working good now I was saved from a major accident, there was a chance to ran over some one as I realised the failure of brake, while the vehicle was in motion. I believe, this a potential claim for a compensation from manufacturer. I filed complaint with General Motors and I did not get a satisfactory reply. They were dragging it without any timely response.

The vehicle died while driving with no warning and had 6,800 miles on it at the time. I received a message to "Push ignition to start" but it did nothing. Had it towed to Cadillac dealership. The engine was replaced. The paperwork that I received says "Large amounts of metal debris in oil. Drained engine oil and found oil to appear silver not brown/black. Suspect major internal failure not allowing engine rotation. Engine requires replacement due to extent of oil contamination with metal debris. I now need to use 0W20 oil. I feel like this isn't solving the problem and I don't feel safe driving this vehicle.

The contact owns a 2024 Cadillac Escalade. The contact received notification of NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling). The contact called several local dealers who confirmed that parts were not yet available. The contact stated that while stopped, the vehicle shut off while depressing the accelerator pedal. There was no warning light illuminated. The contact made multiple attempts to restart the vehicle; however, the vehicle failed to start. Due to the failure, the contact was forced to have the vehicle towed.

The manufacturer was notified of the failure and the contact was provided a case number. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The failure mileage was approximately 15,000.

I was driving on the expressway going 75mph in the middle lane when the vehicle said “press start button” and lost all propulsion. I started slowing down rapidly and was unable to get to the right lane as there were vehicles so I merged to the left lane and came to a stop narrowly missed by a speeding driver. The vehicle would not turn back on. I was in the left lane around 2:30pm with rush hour beginning. I did not feel safe waiting for a tow truck so was picked up by a coworker.

While traveling 65 mph on a highway the car turned itself off and shifted into neutral. I was able to make it to the side of the road nearly avoiding a high speed accident. The car was placed in park and restarted. Less than five minutes later it did the exact same thing again. This time forcing me to come to a complete stop on a highway in a construction zone. The vehicle is only a few months old with 9k miles on it.

Coffee was spilled on center console while transferring cup from Starbucks employee to cup holder. Cup was overfilled and lid wasn’t on properly. Immediately the dash panel started flashing and the service transmission light came on. Drove around a parking lot for a few minutes and seemed okay to drive even with the instrument panel flashing. Had 90 mile drive and during drive message similar to slow down for gear shift popped up and “Service Shifter See Owner’s Manual” came up. When I went to exit freeway and was around 5 MPH the vehicle slammed to a stop. Then would not go into any other gear. As I called for tow driver I turned vehicle back on and was sitting when the vehicle started moving again without my control. I then drove it an additional 20 miles home staying above 20 MPH. Insane Cadillac would design a $120k vehicle with that risk in a very susceptible to spills area. Incredibly unsafe. Beyond traumatizing experience with a vehicle that has leas than 8500 miles on it.

Engine blew up on the highway and stranded my wife and 4 kids on a busy highway. Catastrophic engine failure on a brand new vehicle. GM is doing nothing to help with the situation. They said the engine is backordered and it might be months before they have a solution. This was a new 2024 $125k vehicle. GM has been terrible to deal with. They Refused a buyback. Dealership had several 2024 in for blown engines.

While driving on a major highway and traveling at 80 mph or so, the vehicle flashed a warning light saying “Press Start Again.” I noticed the gas pedal was no longer responding and the RPM gauge dropped to zero. The vehicle shifted itself into neutral and I was forced to steer the truck to a shoulder and scraped the underside of the front ground effect trim. The vehicle then shifted into park and would not start. When a tow operator arrived, the vehicle could not be shifted into neutral to be towed and the electric parking brake kept activating by itself while trying to load and unload the vehicle from the flatbed. The vehicle is now completely immobile and I’m waiting for information from the dealership.

The car started with a rough idle and a check engine light. It was also louder than normal. Driving down the main road approaching a light on the brakes. the light turned green and when I went to hit the gas the car died in the middle of the road. Car would not restart. OBD code P0016 The car is currently at Cadillac service

Engine had a catastrophic failure at 6,232 miles.

ENGINE FAILURE Engine failed at 20k on the highway. The vehicle went into neutral and shut off at 75mph. My wife couldn't get it all the way off the highway and multiple cars about crashed into it. A semi truck locked up his brakes and almost t-boned the car with my wife and kids in it. My wife and 4 kids had to exit the vehicle and run through heavy traffic to get to a safe place. The car wouldn't restart and had to be left in the highway. The wrecker couldn't get the vehicle in neutral to get it up on the flatbed. It had to be dragged in park onto the tow truck. The dealership is saying the engine failed and they have 5 in the shop right now for the same thing. They are saying it will be months before they can get it repaired.

While traveling down I-95 at 65 mph the truck shut down without warning. Extremely dangerous situation. The Cadillac dealership took the truck in and replaced the entire engine. I requested a buy back but was denied. I spoke to the dealership and GM corporate but neither would consider my buyback request.

When accelerating to merge onto highway traffic, engine starting making rattling noise from front left motor and losing power when trying to accelerate.When taken to the dealership stated metal shavings in oil and that we needed a new motor. Dealership would not tear apart motor to see what issue was. Dealership currently had motor. This commonly known defect with gm motors put my family at risk with the loss of power while trying to merge onto highway with cars traveling at highway speeds. There were no warning lights or any check engine lights that came on.

Twice during eight months of vehicle ownership, the vehicle experienced catastrophic engine failure resulting in danger to the health/welfare of the driver. In both cases, the engine has to be totally replaced. The service manager at the dealer acknowledges that Cadillac is selling hazardous/defective products but hopes the vehicle will not experience catastrophic engine failure in the future.

1.What component or system failed or malfunctioned, and is it available for inspection upon request? •The primary issue was with the vehicle’s software system, which was incompletely updated on 9/13/24. This has caused the safety features to malfunction. Additionally, the parking emergency brake engaged suddenly while I was driving. The vehicle is currently available for inspection upon request, as I have already reported the issue and requested immediate attention from the dealership. 2.How was your safety or the safety of others put at risk? My safety,, was severely put at risk when the parking emergency brake suddenly engaged while I was driving. This sudden braking caused me to sustain a strained neck and strained back. I was fortunate to avoid a more serious accident, but this malfunction was extremely dangerous. Additionally, the faulty safety features and the repeated and incorrect engagement of the OnStar emergency system have caused further distress and distractions while driving. 3.Has the problem been reproduced or confirmed by a dealer or independent service center? •As of now, the problem has not been reproduced or confirmed by the dealer. I have scheduled an appointment for inspection on 10/2, and I have made the dealership aware of the issues through my communication. 4.Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? •The vehicle or component has not yet been inspected by the manufacturer, police, or insurance representatives. I have only reported the issue to the dealership so far and requested an immediate inspection and resolution. 5.Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? •Yes, there were symptoms prior to the emergency brake incident. After the incomplete software update on 9/13/24 the vehicle’s safety features began malfunctioning.

I started my Escalade and 5 minutes later I lost power which as the entire vehicle had no power. So I left it alone for an hour or so in my garage and I started up again and this time didn’t loose power. Everything appeared normal and working again. Than the next day I started it up and I had this popup message SD card has been removed press ok to exit navigation (when no SD card was removed). I also noticed that my backup camera, grid lines, or augmented reality has also intermittently not working on days. It sometimes works as normal and sometimes it does not. The message shows Service Augmented Reality System. The following next day, while I’m cruising on the highway the Escalade shifted into neutral when I was going 75 mph and had no mechanical power. So I pulled over stoped the vehicle and shut it off. Restarted after 15 minutes and it operated normally. I’m worried about Safety since it shifted to neutral at highway speed and lost mechanical power, along with other power issues which is extremely dangerous. This vehicle either is a lemon or there is a unknown manufacturing defect and in both cases needs to be replaced due to egregious safety concern.
