CADILLAC Complaints

The contact owns a 2020 Cadillac XT4. The contact stated that upon starting the vehicle, the check engine warning light illuminated. The vehicle was taken to Auto Zone, where it was diagnosed and determined that the EVAP pump (Evaporative Emissions System) was leaking. The vehicle was not taken to the dealer or to an independent mechanic. The vehicle was not repaired. Additionally, the contact noticed that the fuel mileage of the vehicle was fluctuating. The contact stated that the vehicle made an abnormal sputtering sound and delayed starting while pressing the Push to Start button. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was 56,400.

My 2016 Cadillac ATS Coupe has a serious repeating safety defect. The vehicle violently shakes, vibrates, and becomes unstable while driving. This happened TWICE. Both times the rear bolts came out except one. Both mechanics who inspected it said they have NEVER seen this before. The first time, I paid $4,000 out of pocket at another shop. The problem happened again, proving this is a manufacturing defect. My AXP diagnostic on November 4, 2025 confirms major rear differential/axle issues. The vehicle is unsafe and undrivable. One mechanic told me DO NOT DRIVE IT. Cadillac told me the opposite — “safe to pick up” — even though they did no real diagnostic. Cadillac refused to give anything in writing, refused a loaner, and ignored multiple emails. A Cadillac representative told me they reviewed the previous calls, meaning they know the full history. They still refused to fix the dangerous defect. I have paid over $33k, paid $4k for the first repair, still owe $7k, and Cadillac now wants another $7k for the same issue. This is a major safety risk to me and other drivers.

The contact owns a 2021 Cadillac Escalade ESV. The contact stated that the vehicle was taken to the local service center for routine maintenance and after an oil change was performed, the vehicle was started but immediately shut off and failed to restart. The vehicle was towed to the local dealer, where it was diagnosed and determined that the engine had seized and needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure, but no assistance was offered. The contact was informed that the VIN was not included in NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling). The contact related the failure to the recall. The failure mileage was 96,000.

The power steering went out on the vehicle. I was not driving at the time. There was a recall on these vehicles pertaining to the EPS module.

My CT6 had a default engine light on,.Dealer reports broken EVAP line.Car has never been in an accident or damaged.Upon inquiry dealer reports no issues known to them with this problem.However ,this same vehicle had transmission issue when purchased new and the dealer stated same findings.Then recall was issued and transmission was repaired for a known problem and repaired under a recall notice.My concern is this may be similar situation with the fuel EVAP system.The vehicle is my primary car and a fuel vapor leak is a grave concern to me and I believe posses a risk, especially as the replacement parts are unavailable at this time.I have filed an inquiry with Cadillac/Gm #82543696 Steven Maffei(AI inquiry reveals known and past problems with Cadillac EVAP systems)

BRAKE, ABS, Wrench, check engine lights all began intermittently coming on. Before we could bring it into the dealer, it went into "limp mode" while at a very dangerous time and would not move forward while in "Drive". Had to abandon the car in a roadside parking lot. Finally able to get it to the dealer and after their inspection we were told it was NOT repairable. The EBCM module (part of the brake system) was defective and NO parts existed. When we pressed the dealer, no other options or resolutions were offered. Even if a part could be found at eBay, re-manufacturers, or junk yards, they would not touch it. I have had not luck finding a part, re-manufacturer, or repair shop that could be of any help. Right now it is a worthless piece of junk. All correspondence with the dealer has been verbal to this point.

The headlight low beam illumination is extremely dangerous for driving at night. Very poor illumination distance and very poor overall lighting. Can barely even see pedestrians walking if on the side or crossing the road, VERY DANGEROUS!! Have to turn on high-beams when possible just to see at night.

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

The car has a shudder/vibrate and what feels like jerking at certain speeds. I have a 2023 XT5 Premium Luxury 3.6 However, I have taken multiple times to Big O tires had tires replaced, brakes, Lower control arms, I still had a vibration issue. Took back to Big O due to Tire balance issue but came back tires and balance and alignment were fine. I was told that Big O, hooked the car up to a TPS machine and stated my torque convertor needs replaced. My car only has 51,500 miles. They stated that the shudder is between gears 3 & 4. I understand my car powertrain and drive train are under the 70,000 mile warranty. But I keep hearing this is major issue with the 2023 XT5. Making me think I have a lemon since the issue is already happening on such a new car.

The contact owns a 2022 Cadillac Escalade. The contact stated that the message "Low Engine Oil" was displayed prematurely. The vehicle was taken to the dealer, where an oil consumption test was performed, and the contact was informed that the vehicle had passed the oil consumption test.
