Jeep death wobble. Same problem as the 2018/2019 models. Over 45 mph and/or hit a bump and the Jeep wobbles uncontrollably and won’t stop until you slow to almost a stop. Incredibly dangerous for highway driving. There are no warning signs before it happens. This happened to me on a congested and fast moving highway.
Steering, Suspension, Wheels, Mar 25, 2024
Jeep will occasional shake violently at approximately 60 MPH. Had vehicle in to dealer in July 2023. Dealer said problem fixed. Most recent incident March 19th. Commonly referred to as Jeep “death wobble.” Vehicle in shop again.
Steering, Mar 21, 2024
The contact owns a 2021 Jeep Wrangler. The contact stated that while driving at approximately 70 MPH, the vehicle drove over a bump and experienced a death wobble. The contact then decelerated the vehicle to 45 MPH and was able to correct the failure. The vehicle was taken to the dealer, where it was diagnosed that the steering damper needed to be replaced. The manufacturer was made aware of the failure and referred the contact to the dealer. The failure mileage was approximately 38,000. The VIN was invalid.
Steering, Power train, Electrical system, Mar 19, 2024
After a period of 10 minutes in stop-and-go traffic, a shift warning light indicated on the warning panel. All the lights for the gear shift lever would light up individually. The vehicle turned off the stability control system and indicated a warning to proceed driving however the vehicle may not be able to shift into park. After about 3 miles of driving, it felt like the power steering stopped working and it was extremely difficult to control and turn the vehicle. It also felt like the vehicle would not shift properly. Once the vehicle was to the side of the road, it indicated that the vehicle was not in park despite moving the gear shift lever to park. The vehicle would not turn off of accessory mode. Had whatever happened to the power steering happened at any higher rate of speed, the vehicle would have been impossible to control in a turn or traffic. It took every bit of arm strength to coax the vehicle to the side of the road.
Steering, Mar 19, 2024
The contact owns a 2021 Jeep Wrangler. The contact stated that while driving approximately 65 MPH, the entire vehicle began to shake while driving over a bridge. The contact stated that no warning lights were illuminated prior to the failure. The contact stated that the vehicle was taken to the dealer however, the failure could not be duplicated. The failure continued and the vehicle was taken back to the dealer where it was diagnosed with a bent tie rod. The tie rod was replaced; however, the failure persisted. The vehicle was taken back a third time to the dealer and the contact was informed that the steering wheel damper needed to be replaced; however, the part was on backorder. The manufacturer was made aware of the failure, but no case was opened. The failure mileage was approximately 26,000.

While driving vehicle on highway at 70mph, vehicle went completely out of control shaking violently and would not stop violently shaking until a complete stop on a highway. My wife thought she was going to die. Apparently this is known in the Jeep community as the "Death Wobble." There needs to be a recall immediately before someone dies. This is completely un expectable.
Steering, Mar 6, 2024
While driving down the road, whether local road at 45MPH or on the interstate at 70MPH, under certain conditions the front end starts to wobble out of control and I have to stop the vehicle to get the wobble to stop. This is a known problem and on all of the forums you can see discussions about this exact issue. There is a problem with defective steering dampers which may be undersized for the Jeep Wrangler. This has happened on multiple occasions to me. I went to the local dealership early January 2024 under warranty and they confirmed a defective steering damper. They said the part was scheduled to arrive Jan 30, 2024. Today is March 6 and the part is still on back order for at least 45 days as per the parts department. These vehicles need to be pulled off of the road or Jeep needs to be forced to get the parts ASAP. The local dealership said they have several Jeep Wraglers waiting on this part. This is a nationwide problem. Please help get this addressed. Jeep has identified the problem but the lack of parts is the issue. Putting heat on Jeep is what needs to be done. I have attached an article that discusses this issue named the Jeep Death Wobble.

The manufacturer was notified of the failure but did not assist. The contact also received notification of NHTSA Campaign Number: 23V116000 (Power Train); however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The dealer was made aware of the issue and confirmed that parts were not yet available. The manufacturer was made aware of the issue and confirmed that parts were not yet available. The failure mileage was 21,000. VIN tool confirms parts not available.

My jeep has 42,000 miles on it and the entire steering assembly has to be replaced.

My son was driving our 2021 Jeep Wrangler in the town of state college and the power steering pump stopped working - the vehicle has less than 25k miles. He was able to to move the car out of traffic and avoid an accident. He is very lucky as if this would have happened on the 300 miles of highway between our home and state college at 65mph this could have ended in tragedy After waiting three weeks for the first available appt at the dealer - the dealer said the power steering pump is defective. no warning lights, no symptoms of a problem.

While driving our jeep there are many times on the highway that it starts to shake and wobble very bad. To the point where we have to slow down sometimes under 50mph before it stops doing it. It is very dangerous and the dealer keeps telling us when they test drive it it doesn't do it so there's nothing they can do. Stay away from these
Steering, Suspension, Vehicle speed control, Feb 14, 2024
My 2021 Wrangler began experiencing a violent shaking and reduction of steering control in July 2023. The violent shaking would begin if my vehicle hit a bump while traveling at 65 mph or more. To regain control, I would have to brake and reduce speed to under 65mph (which also is extremely dangerous to do on a freeway). Thunder Jeep in Bartow, FL replaced a broken steering component that temporarily fixed the issue. The issue has now returned in late January 2024. I do not feel safe driving this vehicle.
Steering, Suspension, Feb 13, 2024
Steering wheel violently shakes at speeds above 50 mph, essentially if hitting any sort of bump in the road. This is known as the Jeep "death wobble." We received a damper from Jeep that supposedly fixes the problem. That did not fix anything. Steering wheel still violently shakes at speeds above 50 mph. It can shake for short periods of time (5-10 seconds) or indefinitely. We have to completely stop the car, typically on the shoulder of a freeway/highway, in order to get the shaking to stop. My wife and I feel incredibly unsafe while driving this vehicle. The damper took 10 weeks to arrive so we had to just deal with it for that time period. We thought the nightmare would be over after the damper was installed, but that's not the case. We are now left with a very expensive vehicle that we do not feel safe driving.

I have been experiencing the "death wobble" front end issues. It prevents me from highway driving. First experience almost caused an accident. Dealer said it requires a new steering damper but have been terrible with information on if and when part was shipped and when I can expect the issue to be resolved.

was driving on the freeway about 65mph-70mph when suddenly the Jeep started the shake tremendously. Luckily there was no traffic, and I was able to pull over and stop the car immediately. this is a big safety concern as it made it hard to control and traumatizing for the driver. cars should not do that. We are scheduling an appointment to ensure nothing is broken. No warnings were shown when the incident happened.

1.The vehicle shakes uncontrollably when hitting a bump on the highway at all times. Started with only every now and then. Currently I am unable to drive the vehicle on the highway due to safety concerns. If traveling 50 miles or more, steering wheel shakes and whole car shakes until I slow down. Vehicle is available to inspect and drive to confirm. 2.My safety and that of others is put at risk every time I hit a bump on the highway because I have to step on the brake in order to slow down enough in order to get it to stop. Several times I have had people behind me almost hit me, even when in the slow lane. 3.The vehicle was serviced by the Jeep dealership that I purchased it from I believe 3 times. Each time the problem was not correct even though they claimed they replaced a part. I had an independent mechanic (who we trust: this individual services the police car fleet for the department my husband works for). The repair lasted about a year. The shaking has gotten progressively worse over the last few months and now it always happens when any bump in the road is hit, or over a transition from the road onto an overpass, etc. 4.There are no warnings present.

1. Driving 70 mph on [XXX], the road was somewhat rough. I experienced severe wobbling (Chrysler calls this a shimmy) from the front end up to the steering wheel. I had to slow to about 35 mph so I could maintain control of the car. Jeep dealership said the car was manufactured with an older steering dampener. A new one is not available. 2. The display screen sometimes takes over many electrical functions. Heat and defrosting were not working during driving in a snow storm. Both of these deficiencies are safety issues and should be on a recall. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

At about 44,000 miles driving over 60-65 , going over a bump, or going around a curve at.a slower speed the jeep would violently shake, where you almost lose control. I took to the shop they replaced tie rod ends, drag link, track bar and that didn’t solve the issue they now replaced the something with steering and it’s better but still shakes a little when changing lanes. It is honestly the scariest thing ever. Something isn’t right and should be looked into, I am Not the only one with this issue and soon as my lease is up I am getting rid of it.

My jeep wrangler entire dashboard turned red flashing , lighting up that the coolant was way too high. This has happened twice and both times when contacting Jeep corporate it was the waterpump that went bad and now has been replaced twice. Jeep corporate thinks that it is fine to replace a water pump twice in less than a year and a half . Now I have the death wobble where on the interstate at speeds over 60 miles an hour my steering wheel shakes like crazy making it hard to operate my 2021 wrangler unless I get under 60 miles per hour which is a risk for everyone on the road. When telling corporate about these issues. They have full documentation and they say well it’s covered under warranty. Well warranty doesn’t last forever and I am scared for my safety and others. Look at the reviews on Jeep corporate- none are good and talk continuously on water pump issues and death wobble problems . Please help me

Severe car shaking when hitting bump at freeway speed. Diagnosed as the “death wobble” continued to happen more frequently and severely
Steering, Jan 9, 2024
I purchased this vehicle new and the second day I drove it when I hit an expansion joint on the highway the steering wheel started to shake back and forth and the car shook badly. I took it back to the dealer, they said that there was a recall for the problem(which I found out is not true) they worked on it and it was fine until recently. I noticed the problem again with the same conditions. I have just over 36,000 miles on the vehicle now. I took it to a Jeep dealer near me since I have moved. The service manager called it a Death Wobble, which seems to be correct. They told me there was no recall, but seems to be a familiar problem with the Jeeps. They installed a new steering damper, balanced and rotated the tires, and checked the front end alignment. I seldom drive the Jeep, but last month I was going to take a trip and while driving on the interstate at approx. 72mph I crossed an expansion joint and it started to wobble so bad that I crossed into the passing lane. It didn't stop until I slowed down to around 50mph. I immediately turned around and coming back it happened again when I was only going 65mph and it through me into the passing lane again. Had to slow down to about 45mph and pull off the road. I have only put about 130 miles on it since it was fixed. I'm waiting for an appointment for the dealer to get it in and check it out. I got underneath the Jeep and checked to make sure the new part didn't come loose or was leaking oil and it seems fine. I don't understand that if this is such a common knowledge problem with the Jeeps and has been for years from my understanding, why hasn't anything been done to address it?
Steering, Other or unspecified, Jan 7, 2024
Death wobble. At highway speeds, triggered by varying degrees of uneven spots on the road. Severe steering and control instability. Sometimes the vehicle shaking is extremely violent. Must coast down to a varying speed, sometimes down to 65-45mph for the wobble to cease. Happened multiple times, pre- and post-warranty.
