In cold temperatures, the Jeep quadralift air suspension system freezes and shorts out the relay. This renders the air suspension useless and makes driving unsafe. My vehicle was fixed only to have the unit fail a week later with the same issue. There is clearly a defect in the design of the system in that it does not work in cold temperatures.

2018 - "service shifter" message pops up. Over $1000 I had to pay to replace it as it was just outside of warranty time. Past few years, in cold weather, the suspension creaks and cracks noises. Just yesterday, February 2019, less than 5 years old, "service air suspension immediately" pops up on my way home on interstate. Very bumpy ride all the way to my local dealership. I feel I was lucky when I made it, as the tops of the rear tires were angled inward. Apparently, one air suspension "bag" blew out. This resulted in the pump/compressor burning out. Having to replace both bags at the same time and the pump, over $4,300 repair for something no fault of my own and for something that should only happen in cars that are much older in my opinion. Looking online, appears to be many complaints about this. Will Jeep address this issue and maybe "recall" this system so we can be reimbursed? I am about to switch brands as soon as I get this one out of the dealership service dept and anyone else I ever come across who wants to buy a Jeep, I will tell them the horror stories from my current overland, my previous overland, with its 2011 model issues, and my unlimited Wrangler issues before that. I don't hear any issues like these from friends and family with other brand vehicles.

On February 11, 2019, the safety mechanism in the driver's side headrest deployed while the vehicle was in park. This is a safety concern because there was no collision and headrest can affect a driver's ability to remain focused while driving. Mileage at time headrest "deployed" was 78,000. There is also a suspension issue searchable online. The error message reads: "service adaptive damping suspension system." Owner has a 2014 Jeep Grand Cherokee srt. Mileage was 78,000 at time error message appeared. Please contact owner for further information.

I believe there to be a defect with the air suspension compressor in this vehicle, and the same model from other years starting from 2011 until the current model year. At the time of submitting this complaint, there are approximately 200 orders of this part on back order across Canada, and I was told it would take up to 2 months before the part is available for installation. This sounds like a manufacturing defect. I was simply driving on the highway when the display in the car told me to "service air suspension immediately". I drove straight to the dealer to check it out. This part needs to be investigated further as I am very clearly not the only one experiencing issues with major failure of this part, which is crucial to the safe operation of the suspension in this car.

Vehicle was in a level parking lot with a boat and trailer attached. Vehicle was in park configuration with engine running. Vehicle was left unattended for about 1 minute and it rolled about 100 feet, through the parking lot and across a road and down a levee where it hit a tree on the left front side. The driver was not in the vehicle when it hit the tree. The California highway patrol arrived at the scene and there was no citation issued. There was no other property damage other than to the vehicle and the boat trailer. The insurance company paid for the damage to the vehicle less the deductible.

The 2014 Grand Cherokee summit, was serviced on 7/30/15. I had the tires rotated and an oil change. The next day, I got on the freeway and proceeded to do 65mph when the front end and or the steering wheel started shaking violently. I am getting the tires balanced/serviced on 8/19/15 to see if that will fix the problem.

I recently purchased a 2014 Jeep Grand Cherokee. At highway speeds the vehicle will turn, not drift but turn, to the left. I have had the vehicle in for service three times for this issue each time by the service department at cross Jeep in louisville. I was told today that the Chrysler engineers have determined that this issue is "normal" for the 2014/15 Grand Cherokee because of the air suspension. To me this is certainly not normal. At a minimum this is a nuisance problem but also a safety issue when a vehicle will turn to the left on its own. I am very concerned about this issue and equally concerned about Chrysler response or rather lack of response.

The contact owns 2014 Jeep Grand Cherokee overland. The contact stated that the steering wheel vibrated with force when driving over 60 mph. The dealer rotated and balanced the tires several times, however the failure was not corrected. The vehicle was also take to a tire specialist and an independent mechanic, who both inspected the vehicle and advised the contact that the tires were operating normally and the failure could have been due to a defective suspension. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 320. Updated 12/30/14 updated 05/29/2015

Noticed vehicle has creaking noise from the rear portion of the car. Especially when driving at low speed. Suspected was the rear suspension busing. Made an appointment at the dealership to check up.

I saw grease leaking out of both half shaft boots on front wheels and brakes car is in shop to have half shafts replace hoe ever don't no when my car will be fixed.

- Canton, OH, USA

Both cv axle boots leaked all the grease out. Had the axles replaced with new parts from the mfg, and both boots leaked again after only 475 miles or less. Appears that the bands on the boots are not tight enough, or the boots may be too short. They seem to pull apart if wheels are steered close to maximum radius. The issue is that the grease is slung all over the wheels and onto the front disc brake assemblies. This can cause loss of brakes or severe braking issues that can lead to a serious accident. I called Jeep customer service and they are aware of the issue but told me no recall is current. They called my dealer in wilmington nc, and I have another appointment to replace. These will be the third set of cv axles. The Jeep forums online are full of this issue. Seems to be a problem with vehicles built around March/April 2014. This should be a recall with a recognized approved fix. There are probably several vehicles that are affected by this and the owners are completely unaware of the problem as it requires you to look for it. Dangerous.

Driver's side front outer cv joint boot slipped due to an improperly-installed boot clamp and the grease from the joint migrated to the brake splash guard, suspension components, and inside of the wheel on that side. No grease apparent on the brake rotor at this time, however the dealer, grapevine Dodge Chrysler Jeep, in grapevine, tx, has instructed me to drive the vehicle to them for service in a few days. Any grease on the brake rotor could cause a brake failure on that side (leading to loss of control) and would require some parts to be replaced. I understand that this is a common problem with Jeep Grand Cherokee manufactured in March and April of 2014, however the dealer's service advisor whom I spoke with appears to be unaware of the trend and largely ignorant of the danger that it presents.

- Justin, TX, USA

Front cv boot clamp failure: Noted grease on left front wheel, looked underneath to find axle grease splattered all over inside of the rim, brake caliper, and most front left axle components. Clamp which holds the cv joint boot in place at the wheel was missing and cv boot was off, allowing grease to escape from cv joint. The same problem has been reported numerous times on this site, as well as on the Jeep owner forums, and seems to affect 2014 Jeep Grand Cherokee built between early March and mid-April. Many owners have reported both cv boot clamps failing (both front axles), at different times. At this point Jeep has not issued any type of recall for the issue. The affected axle has been since replaced, after a 6 day wait for the part.

Purchased brand new Jeep Grand Cherokee overland 4X4 with a 03/14 build date on May 26, 2014. On May 30th, 2014.....5 days later......noticed an excessive amount of grease on the inside of both front rims. After researching the issue, came across a blog on jeepforum.com that described and provided pictures of others with same build date that had experienced the same problem. Notified Jeep customer care hotline of the issue and they claimed to have no knowledge of issue. Took vehicle to dealership it was purchased from and they diagnosed the issue as a loose clamp on the front cv driveshaft axles. Both sides had to be replaced. Dealership claimed to be unaware of the issue affecting a larger number of Jeep and Dodge owners. How many individuals need to die/be hurt for a recall to be issued for this factory defect? www.jeepforum.com/forum/F309/factory-defect-warning-grease-front-wheels-3-14-build-date-2352729/index18.html.

I purchased my car on 4/5/14 and took it to the dealer on 5/24/14 to have a hitch installed. I received a call from service stating that as soon as they raised my car they noticed that both front axles were "shot". I was told that my car was "undrivable" and by no means could they allow me to take it until the problem was resolved. They gave me a rental. They were unsure as to the reason why until June 2nd when they told me that there was a batch of front axle clamps that were defective, allowing front axle petroleum fluid to leak out. My mechanic told me that had all of the fluid leaked out, my car would spontaneously stop, potentially causing a crash. All cars manufactured from around March-April 20014 have this problem. To my knowledge, new owners are not being notified. I was fortunate enough to have brought it in before an accident.
