“My right side suspension has a hard time coming up and I can hear it then it eventually get to right level and my car is freaking out have every light come on and the windshield wipers but it doesn't always do it but I have videos. The codes I get say malfunctional control u1403 and other ones”

“The contact owns a 2011 Jeep Grand Cherokee. The contact stated that while driving at approximately 70 MPH, it lost automotive power. The contact turned on the hazard lights. The contact was able to pull over to the side of the road. The vehicle stalled but was able to be restarted. There were no warning lights illuminated. The vehicle was taken to an independent mechanic, who informed her the vehicle began to shake and the failure was due to the tip-in. The contact stated that while driving at unknown speeds, the service air suspension message was displayed. The front end of the vehicle was sitting on the tires. The local dealer was contacted, but the vehicle was not diagnosed or repaired. The manufacturer was contacted and referred to the NHTSA hotline. The failure mileage was approximately 55,000.”

“My Jeep's air suspension system (Quadra lift) has failed 4 times within the past year. At the beginning, the only signs there was anything wrong was that it took the vehicle several minutes to raise from the "park" setting and it would sit extremely low when parked for long periods of time. Upon bringing it to a Jeep dealer in October 2021, they informed me the front air suspension lines had a leak and needed to be replaced. A month later, I received an error message that the air suspension system needed immediate repair, at which point we discovered the compressor and relay failed and needed replacement. I was told the car was inoperable in this condition, but they could set the ride height and close the system and it would be driveable. I proceeded to drive the car in this condition for 5 months and ~5,000 miles while we waited for a backordered part to come in. Upon bringing the car into a different dealer after 5 months I was informed it was EXTREMELY dangerous to drive it in this condition (no compressor or relay, static system set at ride height). I was not told why it was dangerous nor why another dealer thought it was okay. The dealer fixed the…”

“THE AIR SUSPENSION - SERVICE AIR SUSPENSION LIGHT CAME ON, THE AIR SUSPENSION THEN LOWERED THE VEHICLE TO WELL BELOW NORMAL RIDE HEIGHT. WE TOOK THE VEHICLE IN TO BE SERVICED AND HAD THE COMPRESSOR REPLACED. 3 WEEKS LATER NOW THERE IS A MODULE AND NIGHT SENSOR SUPPOSEDLY NEEDING TO BE FIXED. NO EXTENDED WARRANTIES COVER THIS AS IT'S AN "AIR SUSPENSION" AND NOT A REGULAR SUSPENSION ACCORDING TO THEIR PAPERWORK. IT'S A KNOWN PROBLEM WITH THESE PARTICULAR AIR SUSPENSION IN JEEP/CHRYSLER/DODGE THAT THEY REFUSE TO ACKNOWLEDGE. THE TIRES COULD BE BLOWN DUE TO THE LOWERED STATE OF VEHICLE AND THE FRONT TIRES CAMING OUT.”

“DELAMINATION OF THE LEATHER TOP OVER THE INSTRUMENT CLUSTER IS BLOCKING VENTS AND CAUSING VISIBILITY ISSUES. ADDITIONALLY THE AIR SUSPENSION IS LEAKING AT CONNECTIONS AT TOP OF STRUTS.”

“A FEW THINGS, ONE BEING HOW MY JGC ABRUPTLY SHUTS OFF WHILE IN MOTION(LUCKILY I WAS EXITING THE EXPRESS WAY (BOTH) TIMES) YEAH, HAPPENED MORE THAN ONCE, TO THE SUSPENSION NO LONGER FUNCTIONING, ALL THE WAY TO IT DECIDING NOT TO START UP.”
