NHTSA Complaint #11493321 — 2011 JEEP GRAND CHEROKEE

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 compressor and relay and within a month the air suspension system started to show similar signs as before where the car was sagging in park and taking a long time to raise, but this time there were absolutely no warning signs or error messages with the car. I brought it in for repair a 4th time and was told the front air shocks and lines had severe leaks, rendering the car inoperable and dangerous to operate in this condition. Considering the frequency in failures and need for repairs coupled with the lack of warnings or error messages I believe this to be a safety risk. There may be many other drivers of Jeeps with the Quadra lift system driving with similar issues and no warnings that could be potentially dangerous.
