Automatic Air Suspension defective. Truck back 2 wheels remains in "off road" mode while the front 2 tires remain in" plant" mode. Brought to carmax after owning for a month. they brought to dealer where is was serviced and fixed at the time. same issue is ongoing after now 2nd attempt to fix. replaced relay part and broke a week later. now having battery and alternator issues along with suspension is still broken.
Car dealership (CarMax) has been not repairing vehicles that are still under warranty and not having loaner vehicles available and having secondary repair shops that are not getting paid to repair warranty issues. My vehicle has been having cv boot issues that have not been repaired as of this date (4/9/2026 .
this vehicle it's located at the New England area where winter eats metal. the links and axis axle are exposed to salt on winter months. see images attached. the whole underline vehicle should have a decent anti rust protective coat. the rear transmission cap should be replaced as well.
At 5 months 3600 miles of ownership the 4 corner air suspension went out. This also caused me to loss my electric stability control of the vehicle. While driving down the highway and switching lanes (before I know of the issue) the truck became very loose. I was driving at the speed limit and just the act of changing the lanes caused the rear end to sway a bit. I feel if this had happened to a less experienced driver they could have overreacted and caused an accident. A 16 year old would have reacted a lot different than myself a 40 year with driving experience in many different situations. The suspension going out in these vehicles is a known problem and needs to be taken care of. Dodge should own up to it. Bottom line, the 4 corner air suspension will cause serious injury or death to someone driving at highway speed when it goes out. …
We bought the vehicle brand new at bill luke in phoenix arizona, after getting the vehicle home we noticed the underneath of the vehicle is rusted and the paint is flaking off. We meet with the district manager of Chrysler and she stated rust is normal on brand new vehicle, they took off a couple of parts, cleaned them up and painted, we asked about all the other parts, engine block, suspension parts, oil pan, outer wheel bearing covers and they let us know they are not going to do anything. The dealership body shop, used touch up paint on the areas the paint was flaking off and that came right off and more paint is flaking off and Chrysler is not going to do anything about that either.
Started having trouble in the steering. Tightening up and hard to steer. Some thing was wrong with the steering shaft. And with this bad it caused the rack and pinion to go bad. Couldn't get it programmed after the shaft was fixed because of the rack and pinion. So its in the shop now and will be in there for over 2 weeks waiting on the rack and pinion.I have had this truck just over a year and I'm having to put over 3000.00 in it. It was hard to steer going around a corner. The wheel would stick and I would have to turn it back. Trying to back up the wheel was hard to turn.
Tl* the contact owns a 2018 Ram 1500. While driving various speeds, the air suspension failed and the "service air suspension" warning indicator illuminated. The air suspension was repaired three times by larry h. Miller colorado Chrysler Jeep (350 s havana st, aurora, co 80012, [phone]), but the failure continued. The vehicle had not been repaired for a fourth time. The diagnostic information was not provided. The manufacturer was notified. The failure mileage was 7,000.
Unpredictable vibrations at various highway speeds. Sometimes annoying other times more severe. This condition also existed on my previous 2017 Ram 1500 that I just traded in. This is the second Ram 1500 that has had the exact same symptoms. I just bought this truck brand new 10/05/19. Dealers cannot solve, and FCA customer care is useless. I suspect this is a know issue with Ram. The standard canned answer is it is the tires.
Air suspension gives out will at high rates of speed. It becomes unsafe to drive. And is not reliable to be on the road as not having suspension in a new vehicle at high or slow rates of speed is a severe safety issue. This is the third time this had happens and will be in the shop again for a quick fix by the dealer. I will be contacting wa state attorney general to do a lemon law as this fall in the un safe category.
