2013 Cadillac XTS suspension problems

“The contact owns a 2013 Cadillac XTS. The contact stated that while driving at an undisclosed speed, the rear suspension was bouncing, and the vehicle became difficult to maneuver. The message to "Check Leveling System" was displayed on the instrument panel. The contact researched and became aware of a recall; however, the VIN was not under recall. The vehicle was taken to the residence and the vehicle was self-diagnosed and it was determined that the stabilizer bar had detached. The vehicle was not repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline to report a failure. The failure mileage was approximately 200,000.”

“Front right passenger side suspension slams hard on the ground while driving at times. It has occurred multiple times and this can be dangerous while driving. It has been checked out and repaired by replacing them but front right side suspension still slams while driving after a few months. This is an expensive problem as well as dangerous.”

“THE SUSPENSION IN THE REAR OF THE VEHICLE WILL SUDDENLY AND WITHOUT WARNING TOTALLY COLLAPSE. THIS HAS HAPPENED WHILE DRIVING AND ALSO ONE FIRST GETTING INTO AND STARTING THE CAR. MECHANIC REPLACED A RELAY SWITCH BUT THE PROBLEM CONTINUES STILL. I HAVE LOOKED ONLINE AND FOUND MANY SIMILAR ACCOUNTS FROM VARIOUS OWNERS OF THIS YEAR AND MODEL!”

“THE SUSPENSION OF THE VEHICLE GIVES OUT AND A CORNER OF THE CAR WILL SLAM TO THE GROUND WHILE DRIVING. IT CAN BE DANGEROUS WHEN DRIVING ON THE FREEWAY. YEAR OVER YEAR WE HAVE HAD THE " SERVICE LEVELING SYSTEM " ERROR COME UP FOR OUR VEHICLE. IT IS NOT ONLY EXPENSIVE BUT DANGEROUS TO DRIVE NOT KNOWING WHEN THE SUSPENSION WILL GIVE OUT. DEALERSHIPS HAVE MADE MULTIPLE REPAIRS AND UPDATES TO NO AVAIL. NOTHING SEEMS TO FIX THE PROBLEM.”

“I PURCHASED THIS CAR IN DECEMBER, 2019. THE FIRST PROBLEM IS THAT THEY HAD TO CHANGED THE RADIO. THE SECOND PROBLEM WITH THE CAR IS THAT THE HAZARD 4-WAY FLASHER STOPPED WORKING AND WAS ON PERMANENTLY AND BECAUSE OF THAT IT KILLED THE CAR BATTERY. I CALLED THE CADILLAC DEALER AND THEY TOLD ME TO BRING THE CAR IN. I GIT IT JUMPED START AND TOOK IT IN THAT WAS IN AUGUST, 2020. THEY TOLD ME THE SWITCH WAS NO LONGER GOOD AND NEEDS TO BE CHANGED. IT COST ME OVER $400 TO BE FIXED. ON THE DAY I PICKED UP THE CAR I NOTICED IT A SIGNED ON THE DASH BUT I DID NOT KNOW WHAT IT MEANT BUT THE CAR STARTED TO BOUNCE. THE FOLLOWING DAY I WAS ON MY WAY TO NY FROM NY SO I TOOK LOTS OF HIGHWAY, FROM 287, RT 80 AND SO ON INTO LONG BRANCH, NY. ON MY WAY I ALMOST LOST MY LIFE BECAUSE THE CAR WAS BOUNCING OUT OF CONTROL. I CALLED THE DEALER AND REPORTED WHAT HAD HAPPENED. MATTHEW TOLD ME TO BRING BACK THE CAR TO SEE WHAT HAPPED. I LEFT THE CAR FOR COUPLE OF DAYS I THINK IT WAS 8/28/2020. HE CALLED ME ON 9/1/2020 TO LET ME KNOW THAT THE AIR SUSPENSION CONTROL MODULE HAD FAILED AND IT WOULD COST ME OVER $1700.00 TO BE FIXED. SINCE THAT TIME THE CAR HAS BEEN SITTING IN MY DRIVE WAY AND…”

“AFTER DRIVING AROUND TOWN FOR 30 MINUTES, I PARKED THE CAR, SHUT OFF THE ENGINE, GOT OUT TO TALK TO A NEIGHBOR 6 HOUSES AWAY FROM WHERE I LIVE. 10 MINUTES LATER, I GOT BACK IN THE CAR, AND DROVE FOR HOME. THE FIRST LITTLE CRACK IN THE ROAD MADE THE CAR RIDE LIKE A GO CART. AFTER A FEW MORE FEET, I COULD TELL SOMETHING WAS WRONG, SO I PULLED OVER, AND GOT OUT, AND SAW THE REAR OF THE CAR SQUATTING DOWN TO WHERE THE TOP OF THE WHEEL OPENING WAS WAY PAST THE TOP THE THE REAR TIRE. I LEFT THE CAR RUNNING AND COULD HEAR THE AIR COMPRESSOR RUNNING, AND WATCHED TO SEE IF IT WAS RAISING THE REAR END TO A LEVEL POSITION, BUT AFTER 30 SECONDS, IT WASN'T RAISING. SO I GOT BACK IN AND LIMPED HOME, SCRAPING THE STREET AS I TURNED IN TO A SLIGHTLY INCLINED DRIVEWAY, AND PARKED IT IN THE GARAGE AND SHUT OFF THE ENGINE. I GOT OUT TO LISTEN FOR THE AIR COMPRESSOR TO KICK ON AND AFTER 2 MINUTES, IT DID NOT KICK ON, SO I GOT BACK IN THE CAR AND STARTED IT UP, THEN GOT OUT WHILE IT WAS RUNNING , TO HEAR IF THE COMPRESSOR WOULD KICK ON THO RAISE THE REAR END UP TO LEVEL. IT DID NOT KICK ON, SO I SHUT THE ENGINE OFF, AND LET IT SIT FOR AN HOUR, THEN GOT IN IT AND STARTED IT UP, AND…”
