2021 Jeep Gladiator

SUSPENSION: 2021 Jeep Gladiator - 12,000 Miles: On several occasions at freeway speeds vehicle hits uneven road / bumps and vehicle looses steering control like it jumps off the pavement / shutters over road way with no control: At one point I thought I blew a front tire and did loose some control of vehicle and pulled over to shoulder to scope it out: No tire blew: This is a major concern: My safety and the safety of passengers are at risks: I would not put my family members in this vehicle other than city driving!! Tried contacting MOPAR but was unable to do so - 12 March 2022 - A Joke

I was exiting the freeway with a speed limit of 75 mph. On the off-ramp I lost control of the Gladiator. The front end wobble was so bad that I could not hold onto the steering wheel for fear of breaking my wrist. Instead I had to wrap my arms about the wheel in an attempt to stop the wobble. I was unable to keep the vehicle in my lane, and finally ended up in a large ditch next to the off ramp. What happened appears to be a problem with the Mopar 1.5" lift kit installed by the dealer. The kit was installed 8/17/2021. This incident occurred in Jan 2022, about 4,000 miles later. I had the kit installed and then inspected about a month later specifically to check for any loose bolts, and to double check the torque for the bolts. The CV bar in the front lost a the bolt on the passenger side, dropping the cross bar and resulting in total loss of control of the passenger side front tire. I felt very lucky not to have been injured, and not to roll the jeep. It took about 150 feet to stop the vehicle in the ditch. I am attaching a photo of the bar held in place after the accident using bungie cords. This was done just to get the bar off the road and allow for moving the vehicle. The mechanic was able to secure the cross bar with a new bolt. The original bolt and nut were not found. We speculate that either the bolt was not torqued correctly or might have been missing a lock washer. At any rate, potentially this could have resulting in much worse. If this happened just a few seconds earlier on the freeway, the damage and injuries could have been much worse. Now the vehicle is driving like new, after new bolt and alignment. However, I will be checking those bolts more frequently, particularly if I notice any extra play in the steering. Before this happened, the play in the steering had increased. I thought I just needed an alignment, but it was much worse than that. Really I would think this cross bar needs redesign to ensure it can't break loose.

The "death wobble." When driving over 55mph even the slightest bump will set off a violent chain reaction of vibrations. This causes unsafe driving conditions and loss of control. The only way to regain control is to quickly slow down to less than 55mph and at highway speeds this is extremely dangerous. Jeep has failed to fix this and wont even acknowledge that it is an issue.

In January 2021, my 2021 Jeep Gladiator Overland became unstable at normal freeway speeds (60-75 mph) on many occasions. The slightest bump or surface irregularity stimulates a violent and sustaining side-to-side vehicle shudder/vibration from the front suspension that was very extreme that lasted for over 2 minutes or until the vehicle slowed to around 60 mph; where stable vehicle behavior restored. This extreme instability and needed hard braking creates a serious driving hazard. I have taken it to 2 separate dealers who cannot find any issue and are unwilling to investigate unless it happens in their presence even with video proof. I have also taken to a tire shop and had the tires re-balanced and put on a road force machine. The tire shop found no issues with the tires or balancing. This started at about 23,000 miles and occurs more as the temperatures drop. This failure mode is severe, occurs without warning, is not detectable until it occurs and is very frightening. My Jeep has stock, factory wheels and factory tires in good balance with no visible or abnormal tread wear. This is a dangerous condition that needs immediate correction. A 1 year old vehicle with 23,000 miles in excellent condition, no accident history and no modifications should not be doing this. Side note; I did have to have the engine replaced after 11 months of ownership and the Jeep came from the factory with cracked spark plugs and had the spark plugs replaced after 1 week of ownership. This is an ongoing issue with no resolution.

In December, 2021, my 2021 Jeep Willys Gladiator became unstable at normal freeway speeds (70-75 mph) on ~8 occasions. At these speeds, the slightest bump or surface irregularity stimulates a violent and sustaining side-to-side vehicle shudder from the front suspension that was so extreme that it splashed my cola and ice from the center cup holder to the dashboard and doors. R-L-R Steering inputs had no effect and hard braking had no effect until the vehicle slowed to around 60 mph; where stable vehicle behavior restored. This extreme instability and needed hard braking creates a serious driving hazard. The dealer is installing a new steering damper. The engineer in me says there is a bearing, bushing or ball joint as root cause. This defect manifested at ~23,000 miles and occurs more readily as the temperatures drop below 20 deg F. This failure mode is severe, occurs without warning, is not detectable until it occurs and its effect is panic-inducing. My Jeep has stock, factory aluminum wheels and normal sized Michelin All-Season radial tires in good balance with no visible or abnormal tread wear. I ordered this vehicle new on 3/1/2021. The 'Gladiator forum' calls this condition "death wobble". Anecdotally, the condition appears to be associated with vehicles having "lift kits" as well as stock vehicles. My 'Willys Jeep is built by FCA with a modest suspension lift relative to the base Gladiator models. Other (anecdotal) owner information has identified loose ball joints, defective drag link bushings and steering free play as root causes in other new, low mileage vehicles. I am a retired engineer with vehicle development, professional driving and prototype vehicle experience. This is a dangerous condition that needs immediate correction. A 7-month old vehicle with 25,000 miles in excellent condition, no accident history and no modifications SHOULD NEVER DO THIS. A steering damper may reduce this death wobble but there is a more likely root cause.

My jeep has bottomed out multiple times on normal road bumps. I've owned 4 other jeeps and have never experienced this before I've noticed there is one 3" of travel allotted between the front axle and the bump stops and I under stand that the diesel motor weight more than the 3.6l but to not compensate for the extra weight and running the same suspension setup as the 3.6l is not even right.... To spend 57,000$ on a vehicle that I can't just drive down the road without having to watch for bumps or manhole cover because I don't want to jar my back is no peace of mind.

Experienced death wobble-violent shaking of steering wheel and car side to side -on highway on 1/6/2022. It happened twice, 5 mins from my home. Both incidents occurred in expressway. Once while traveling 70mph and had to swiftly change two lanes in rush hour traffic to the slow lane. The shaking stopped stop at reduced speed to 50. Then the second time minutes later I was going 57mph in the slow lane and the violent shaking started again. Luckily it was at my homes exit. I slowed down and drove the 4 blocks on the streets straight to my garage. Called Jeep next morning and they can’t pick it up until Wednesday, January 12. Bought this truck brand new from Jeep in May 2021. When I test drove it, steering pulled to one side. Had it aligned as part of the purchase. Months later I had steering problems and took it to them and they changed the track bar. A few weeks ago I did an oil change with them and they rotated the tires. And now I got the death wobble twice yesterday. There’s something in the suspension that’s either broken, loose, or worn out. I don’t feel safe.

Rear Axle Assembly leaking fluid onto rear brake drum and wheel hub assembly, potentially rendering brakes non-functional in rear of vehicle. Excessive drift/play in steering at moderate speeds (40mph+) "Death Wobble" experienced at speeds ~70mph. Front wheels/suspension near total loss of control. Steering column violently shuddering, and required excessive force to control. Vehicle is dealer stock, completely unmodified, with only 9500 miles on it. Dealer currently has vehicle. Replaced rear axle assembly. Currently test driving to try and reproduce shaking in steering and front drivetrain.

8000 miles on new purchase, never off road, this Jeep goes into a violent shimmy/wobble 60-70 when in an ever so slight off of center steering angle on the freeway after crossing an expansion joint or other sharp road irregularity. Coasting down is the only way it goes away. Full Throttle acceleration out doesn't help, nor hard braking. It's NOT consistent, but it's happened to me three times in recent weeks as the summer temperatures subsided from the 80's F into the fall 40-60 F. Again, purchased brand new May 2021, tire pressures are proper, only driver, no other passengers or cargo. The onset is unexpected and frightening. The local Dodge / Jeep dealer where I have had one oil change seems to be unaware of a fleet issue or problem. It seems to be widely reported on various automotive blogs. Please help.
