CADILLAC Complaints

The vehicle experienced a total engine failure on 03/16/2026 while traveling in the Houston/Friendswood, TX area going home from our vacation in Galveston, TX. The vehicle remained out of service at Big Star Cadillac in Friendswood until 04/27/2026. This failure is directly related to GM Safety Recall N252494000, involving defective internal engine components. Prior Ownership History (01/22/2024): The vehicle experienced an engine failure at 18,424 miles while under previous ownership. The engine was replaced by an authorized Cadillac dealership prior to my purchase. This material repair history was not disclosed at the time of sale. Second Failure (03/16/2026): At 47,503 miles, the replacement engine (N1240062M69X0196) failed catastrophically while in my possession during a return trip from vacation with my family of five. The failure occurred on Interstate 45, a heavily traveled highway, and we were barely able to exit the freeway. The new engine is part of the N126086N44X0534 series.

My vehicle lost full engine propulsion going 70mph on the highway. We were blocking lanes of traffic and lost speed at a very rapid pace. No engine or warning light came on before the car lost engine and shifted into neutral. We called 911 and the California Highway Patrol had to assist in us not getting hit from behind as our car was disabled and would not restart to move off of lanes of traffic.

High-pitched squeal under light braking at low speeds (under 10 mph), typically occurring during the first few stops of the day...Dealer stated TSB Numbers: 20-NA-002 or MC-10232149-0001 only refers to 2020 model year. Please update this TSB so it includes 2024 model year XT4 vehicles. Dealer unable to replace break pads and charge GM without updated TSB. Note: Issue has been ongoing since purchase of vehicle and both dealers in Michigan (where purchased) and Indiana stated humidity. Recently, Indiana dealer (Lockhart Cadillac Fishers) got more and more vehicles back so now believes it should have a TSB to fix due to noise caused by semi metallic pad issue. Dealer charging $469.78 to apply anti squeal to pads which they know is only a temporary fix (so not recommending it). Dealer cannot help unless GM acknowledges issue.

Had three different incidents: 1st occurrence was at a red light and vehicle stalled and would not restart. Jumped the vehicle and went on my way. 2nd time was traveling at 40 mph and engine killed. Jumped it again and it started. 3rd time vehicle was parked and would not start. Had it towed to dealership. They determined it was a bad fuel pump power module. This is a dangerous reoccurring issue with the Cadillac XT4 which demands a recall!

On April 30,2026 I was pulling into a parking space and the gear shifter wouldn't go in to park with my foot the brake and the gear shifter wouldn't go in to park with my foot the brake and the gear shifter wouldn't go in to park . The tow truck driver who finally responded was able to lift the rear of the car up to see what was wrong with my car and I was placing it in the back of the he determined the cable for thre gear shifter was broken.

On 3rd differential in 2 years. Dealer won’t fix without us paying ANOTHER $4,700. There is NO way a differential goes 3 times in 2 years. Something is wrong. Help!!

2018 Cadillac Escalade ESV Platinum, 6.2L V8 L86 engine, under 100,000 miles. Engine seized and was towed to an authorized GM dealership. Teardown confirmed a spun and twisted rod bearing resulting in complete crankshaft seizure, documented by the dealer as non-serviceable per GM, requiring full engine replacement. Component is available for inspection. Prior to seizure, the vehicle experienced a highway stall preceded by a harmonic balancer failure, belt system failure, and charging system collapse. The vehicle lost propulsion at highway speed, creating a crash risk to myself and other drivers. The failure mode, spun rod bearing with crankshaft damage, is physically identical to the defect documented in GM Safety Recall 25V-274, covering connecting rod and crankshaft manufacturing defects in 6.2L V8 L87 engines in 2021-2024 vehicles. The L86 and L87 are variants of the same Gen V small block architecture with the same bottom end design. I contacted Cadillac Customer Care and requested a Field Technical Specialist review. GM instructed the dealership to delay filing a technical assistance case until my third party warranty determination was made. GM subsequently refused to file any technical case, stating the L86 is not included in the recall and they have no plans to include it. The failure has been confirmed by an authorized GM dealership. I am requesting NHTSA evaluate whether the recall scope should be expanded to include 2018 L86 engines, and whether GM's refusal to conduct technical investigation while directing a third party warranty to absorb a potentially recall-related repair constitutes inadequate recall handling.

2023 Cadillac Escalade ESV - passed Safety Recall N252494001 L87 in August of 2025. March 2026 experienced loss of propulsion (while driving), major noise and violent shaking. Every warning came on. There were no other symptoms Very fortunate no one was behind us as vehicle completely stopped on road. Reported problem to dealer and took into them. Said it was serpentine belt and we were charged to replace (they never showed us the belt nor took a picture of it. In April 2026 the same exact issue occurred with complete propulsion failure (vehicle dies abruptly with significant noise and shaking) on the road near home (nearly hit by following traffic). Called dealer, told to not move the vehicle and we had to have it towed to same dealer. In shop now for 2 weeks, we have heard 3 different reasons with no fix of the issues. They will not call us. We have to phone them and it is a different issue each time we call. We were told GM is involved; but we have had no verification.

The contact owns a 2013 Cadillac XTS. The contact stated that several codes will intermittently illuminate on the vehicle, such as code 813, which refers to a transmission communication failure; a malfunction with the Instrument or Cluster (IPC); and code 62, which refers to the Body Control Module (recalls 13 and 158). The Power Steering, Drive Carefully, and Suspension warning lights would illuminate. The instrument panel would suddenly black out, or certain monitoring systems, such as the speedometer, would fail. All failures would occur intermittently. The vehicle was taken to a certified mechanic, who informed them that water intrusion into a bulk cluster behind the bumper of the front passenger's wheel, where several wires for different systems of the vehicle are interconnected. The vehicle was drained, dried, and sealed with silicone. The failures persisted. The contact completed some research and learned of NHTSA Campaign Number: 14v116000 (Service Brakes, Hydraulic) online, which they believed could be related to their failure. The dealer was contacted, and it was confirmed that the VIN was not included in any open recalls at the time. The vehicle was not repaired again. The manufacturer was not informed of the failure. The failure mileage was approximately 156,000.
