Customers report that 4-corner air suspensions in Model Year 2013 to 2019 Dodge Ram 1500 trucks and Model Year 2013 to 2019 Jeep Grand Cherokee SUVs fail in temperatures below freezing.

NHTSA complaints detail the dangers that occur due to this defect: 

“The service air suspension display comes on and instantly goes out with no stored codes according to dealership. While driving the rear air bags dump (deflate) completely empty. There has been times where this has happened at 70 MPH other times it has happened at 35-55 MPH. This causes the truck to bounce violently and have sway side to side when going over bridges and bumps.” NHTSA ID: 11444284

“I was driving down the road when the air suspension went out. My truck started bouncing and I almost lost control of my truck. I had to pull over and see what the issue was. The air suspension works when. It wants too. It’s very dangerous driving on the freeway when the suspension goes out.” NHTSA ID: 11432986

“Just like so many others, the air ride suspension service immediately message comes on at different times. the truck deflates to ride on no suspension and bounces and swerves every time you hit a bump. super dangerous” NHTSA ID: 11398686

“The vehicle’s air suspension system suddenly failed during driving. the air suspension system controls the ride height of the vehicle, and the ride height also impacts the vehicle’s steering alignment. my understanding is that the issue is that the nitrogen air suspension system performs a self-check upon start-up and purges a small volume of air and ingests outside air, which contains moisture. during the winter months, this moisture gets into the suspension’s compressor, and causes premature failure due to freezing. the cost of repair/replacement for this air suspension compressor is $1200, and will fail again when the same cycle repeats. chrysler/ram is aware of the issue, and there are tsb’s about air suspension issues, and multiple customer care cases, but they refuse to issue a recall. if this system fails during driving it can cause a sudden loss of control due to vehicle geometry changes. i was on a highway when this happened, and had to pull over to the side of the road, as the warning said seek “immediate repair” of the air suspension system. i contacted chrysler, which acknowledged the issue, and opened a case, but later denied the case. this issue is documented among many other chrysler air ride suspension vehicle equipped owners. the only recourse is to replace the system with like parts (which fails again), or to swap the air ride system for traditional coils and spring suspension, which is costly.” NHTSA ID: 11398569

Customers report being told by dealership technicians that the issue could not be duplicated or that there are no stored codes after the service air suspension display comes on. Customers report recharging the air suspension system costs $200, and once repaired, the suspensions “go bad again.” The cost to replace the air suspension system can be between $1,000 – $3,000. 

Dodge faced a Canadian class-action lawsuit alleging failure of the 4-corner air suspension in Model Years 2013-2020 Dodge Ram 1500, Dodge Ram Rebel, or Jeep Grand Cherokee.  This air suspension system defect allegedly causes operators of the vehicles to experience issues with safety, comfort and ride quality.
