The Side Detection System warning light came on. I found that other vehicles in our blind spots were not be recognized by the system. The warning lights were not being activated on the side mirrors. The system was repaired at the dealership at a cost of $865.43. When speaking withe the service technician he said this is happening quite frequently. They found three wires that were corroded and two more that showed signs future issues.

I took my SUV to Heritage Cadillac in Lombard, IL for a revving sound while accelerating, specifically from 0-35mph and then acceleration on the highway at higher speeds. It sounded like I was revving the engine even when I wasn't accelerating and stay at a constant speed. There were not any service lights or notification of any issues in my vehicle. The car is at 59,000 miles, I paid $230 for a diagnostic run only to be told it was a "Faulty Muffler" and needed replacement for $1479.66 as it was not covered in my extended warranty. When I took it for a competing bid at a national-brand muffler shop, I was told parts were very hard to get for it as the car was "so new" and that he had another customer bring in for the same problem, but he couldn't find the muffler in his national data base. This lead me to research further why this would happen to a car only 5 year in. This led me down a rabbit hole researching this issue on other Cadillac forums. I'm seeing a recurring pattern among 2020-2021 XT5 owners with the 3.6L engine: a whiny noise when accelerating at low speeds, peaking around 3,000 RPM, traced to loose baffles inside the muffler or a restriction in the exhaust system. Several owners report first noticing it as early as 2,000 miles, with it getting louder over time - which lines up closely with what I experienced. More notably, multiple owners with this exact symptom got their full exhaust systems replaced under warranty, including vehicles with comparable or higher

When braking — both at low speeds and when slowing from highway speeds (40+ mph) — vehicle feels like engine revs and is still pushing against the brakes. Requires very firm pedal pressure to hold car in place; if brake pressure is eased, vehicle surges forward until it finally settles after several seconds. Concern is intermittent but repeatable. I had a near collision on 10/3/2025 due to this issue. I have been in constant contact with the dealership on this, including the service manager, as well as Cadillac Care. The dealership has test driven the vehicle several times and has been unable to replicate the problem. However, I do have an audio recording of the engine’s idle speed at various points during one incident.

Car exhaust was making vibration sound brought into dealership and the muffler is broke on the inside. Cadillac repair said it’s not a common occurrence and was not covered under any warranty. Stated it could have broke on the inside due to vibrations. The muffler shouldn’t have just broke inside due to vibrations if the integrity of it has to of been compromised especially if the car isn’t that old and there’s no damage.

See attached document for complaint

At a red light in traffic, it suddenly shut off the engine, emergency brakes went on, multiple warning lights were on (Low Bat, Low fuel {full of fuel}, lower passenger window, etc..), totally immobilized itself by not being able to start the car or push it with the brakes on! 81 year old female driving and if the car did this at highway speed it could have been a catastrophe! It appeared everything else in the car was working but had 'self immobilized'!

Update - Original event was the power steering automation system failure which left the vehicle with no power steering system. When car rested over night the system operated properly. Took it to dealer today and they could not find any mechanical failures or wiring failures. A software update for the power steering module was available and they did the software update. Loss of power steering when driving is a very serious event, as the vehicle is almost impossible to steer. A woman or weak elderly person could not move the wheel at all, which could easily result in a serious accident if driven at high speed or on a windy road when the system failed. Since Cadillac had already developed the software update, why was that not made a recall. Why wait until it fails and results in an accident? Cadillac clearly knew that was a possibility. I think NHTSA should demand a recall to update all the 2021 XT5 vehicles.

The power steering suddenly shut down while driving, making steering almost impossible. Luckly I was on a straight part of the road and close to my house. It would have been disastrous if it occurred at high speed. I understand there is a recall to replace software on some 2021 Cadillac vehicles but mine is not in the list. I think my vintage of vehicles needs to be added to the recall list

My new car has a serious lag issue. The car is not responsive to the gas pedal. You have to press the gas a lot to get moving. Once moving a lot lag. If I press it fast. Completely non responsive. My car is slower than any other car I have driven. Although this is 310 HP. Feeels like 150 HP. And I get only 12-15 miles to the gallon. Regular driving in suburbs and highway.
