2024 Cadillac XT4 problems

“The car unexpectedly braked. There was nothing in front of the car & I was traveling only 20m/hr. The car stopped so abruptly my sunglasses flew off. Then i was hit from behind by a landscaping truck.”

“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.”

“While driving the complete dash will go black: no radio, gauges, speedometer, etc. The total blackout lasts for about 30-45 seconds and then different gauges, speedometer, etc will slowly come back to life. During this blackout period I have no idea of my speed nor what other functions, like ABS, might be off-line also.”

“Problem with the fuel pump control module. Car broke down in front of my neighbor’s house. Now there is a problem with the transmission. It is slipping and there’s a clunking noise.”

“I was driving down the road and my vehicle lost power and quit running. Luckily I was in the lane closest to the shoulder and was able to pull over on the shoulder and was not able to restart my vehicle, but had this happened in another location this could have been a huge safety problem for me and others with the vehicle completely losing power while driving in the middle of traffic on highway 27. The vehicle is still under warranty and has 10k miles. I am the only owner of the vehicle and it has only been serviced at the Cadillac dealer. The Cadillac dealer was able to inspect my vehicle and determined that the fuel pump module went bad and replaced it and advised that this has happened to other Cadillac, GMC, and Chevrolet suvs.”

“Purchased used with 30k miles and under factory bumper to bumper warranty. Noted noise when turning right slowly into parking space from front suspension as well as pop sound while going over speed bumps. Dealer replaced 3 axles (2 driver side) and confirmed noise present. Also replaced strut assembly in front which did not assist. Suspension issue unresolved to date and GM Field Tech suggests “operating to spec”. The main issue noted is the leerching forward between gears when braking to a stop. It’s as if car is sliding into each gear , learching while brakes applied, until stopped. This could cause accident and harm to occupants. Transmission is the 9 speed T950. Dealer replaced valve body and fluids and then Field Tech revisited and said “operating to spec”. It is unknown if issue related to transmission, electronics shift coding , or torque converter. I currently own 4 GM products and have owned over 20 without this issue.”
