2021 Jeep Wrangler

June 5, 2025 stopped at red light turned green tried to turn left and the jeep flashed the electric red bolt symbol and check engine light came on lost all power would not go when gas pedal was pushed. a/c lost power started blowing hot air and engine turned off. Restarted engine finally got it to go enough to pull out of traffic. Turned off engine opened hood checked battery cables, fuses and all was intact. Started engine drove slowly to the Autozone store to have the diagnostic test done and it showed P2101 power train system throttle actuator A control motor circuit range /performance detected unexpected voltage on the throttle actuator control motor circuit also C121C-00 ABS torque request signal denied Anti-lock Brake System U0401-00 implausible data received from ECM/PCM “A”. System was reset to be able to drive home. 6/16/25 went to start jeep to go to work made a clicking noise check engine light on and the voltage warning sensor flashing and showed Service Electronic Stability Control error would not stay running checked battery cables fuses and restarted engine tried to back out of driveway engine would not go. Had jeep towed to Moore CDJR dealership where it was purchased from 9/2023 to have serviced found throttle body needs replaced dealership contacted several parts dealers, Mopar, and other dealerships etc. to locate the part needed was advised couldn’t find the parts needed for the repair. Contacted service department and they advised they were calling National Auto Care my extended warranty for approval for repair. My concern is if I had been driving 65 mph and it went out I would have been in a accident when the vehicle stopped functioning. Safety of myself and other drivers would have been compromised. This is the 2.0L Turbo motor and have been advised that there are several issues with this motor and should trade in vehicle. I don’t have that option and this is the only vehicle I have.

Death Wobble/uncontrollable shaking when vehicle hits any kind of inconsistencies in the road, especially on the freeway. Yes it’s available for inspection upon request. I have taken it to the local Jeep dealership mechanics and Les Schwab auto center to have the problem inspected/fixed and both have told me “everything looks fine” but it is absolutely not fine when I have to put my hazards on and pull over to almost a complete stop to get the shaking to stop on the freeway. It’s terrifying. No lights or warnings happen before the incident occurs.

I am writing to formally express my frustration and concern regarding an ongoing issue with my 2021 Jeep Wrangler Unlimited. For several years, I have experienced severe shaking in my vehicle when driving at speeds between 50-70 mph after hitting a minor bump. The vibrations are so severe that it feels like the vehicle is going to shred itself in half. The issue has gotten worse over the years. Once this occurs, it requires rapid deceleration to 40 mph for the issue to subside. Most concerning is that on [XXX], this shaking occurred twice while driving in heavy traffic on [XXX] with my [XXX] son in the back seat. The severity of the issue poses an undeniable safety risk—not just to me and my passengers, but to others on the road as well. Given Jeep’s reputation for durability and off-road capability, it is deeply disappointing that such a serious issue is not being addressed with more urgency. After the event on [XXX], I initially addressed this issue with a Jeep service center at Dellen Chrysler Jeep and Dodge in Greenfield, IN. I was informed that the problem was related to the steering damper. However, despite recognizing the issue, my vehicle has yet to receive the necessary replacement due to a nationwide shortage of the part more than 2 months later. I implore someone from Dellen, Jeep, and/or NHTSB to do the right thing and properly warn owners about this serious safety issue. As a consumer and Jeep fan, it is unacceptable to me that: 1) A vehicle fails this catastrophically during normal driving, putting the public at risk. 2)Jeep doesn’t have sufficient inventory to fix the problems. 3)Jeep isn’t doing anything to make owners aware of this seriousness of the issue.

Steering damper has been replaced 4 times due to random starting of violent shaking when hitting a bump on the highway. When this shake occurs the vehicle is harder to control and entire vehicle shakes. It was replaced 4 times but they had 6 chances to permanently fix this issue. Some times they chose not to do any work on the car. Being as this makes the vehicle harder to control, hitting another bump while shaking causes dangerous unpredictability when driving. The jeep dealership was able to recreate the shaking before replacing the steering damper each time. The part was inspected and prepped by the mechanic each time before being replaced in my vehicle. There are no indications such as warning lamps or messages prior to it happening it is unpredictable. I was told by the mechanic the last time it was replaced that this is an ongoing issue with 2021 Jeep Wranglers and that Jeep keeps updating the steering damper part but the have yet to be able to fix the issue with all the new updates to the part they are making. The first time it occurred was at about 17K miles and my car is now at 45K miles, so it has been replaced 5 times in the span of 28K miles

Extreme steering wobble at speeds over 65 mph when hitting bumps on the highway. First time was with about 20,000 miles didn’t not know what it was, and it stopped after slowing down. After more times this happened I want to the dealer my warranty was expired and the want to replace the steering stabilizer to start. This problem now happens about every 5 miles on the highway and I fear losing control so I don’t drive over 65 mph with this vehicle. What can be done to fix this

The following is copy of an email sent to JEEP CEO in November and then again in January. I have not received a response. I have also sent an email to the dealer. I ask NHTSA to look into Dear Mr. [XXX] : I would like your assistance in a major issue I am having with my 2021 Jeep Wrangler Sport. I have contacted the dealer (Airpark Jeep- [XXX] ) and your corporate customer service department with both saying they are unable to help me. As I am sure you know, social media has a lot of information on what is referred to as the Jeep Death Wobble- A problem with the stabilizer bar. My jeep has this issue and it hits mostly at highway speeds causing the entire jeep to shake violently until the jeep settles down. This is now happening too many times and there is nothing the driver can do, but hold tight on the wheel and hope the shaking doesn't cause an accident. I can not believe this was not addressed via a safety recall! This problem has the potential in my opinion to lead to serious injury or death of passengers in the jeep and others nearby! I will be turning the jeep in at the end of February and I assume the dealer will have to fix the problem (I am told it takes a couple hours to replace the stabilizer bar), before the vehicle is sold as a used jeep. To allow this condition to exist is inexcusable by both Jeep HQ and the local Jeep dealer. Because this has been a known issue and Jeep and your dealers have done nothing to resolve this problem, I will not simply go away. I and other jeep owners are owed something more than "We can't help". I have owned two CJ-7s, one Grand Cherokee, and now my Wrangler Sport. As part of a Sheriff's Search and Rescue Team, I am required to have a solid 4-wheel drive vehicle. Based on this experience and a few other issues that were not resolved, I will now consider purchasing the Ford Bronco instead. I would like the courtesy of a response please. Thank you, [XXX] [XXX] Deputy Director FBI NEIA INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION A

On three separate occasions the vehicle began violently shaking giving the impression the front wheels were coming off (aka the death wobble). On all three occasions the shaking started while driving straight on paved road at 45-60mph. The first two incidents occurred within a week’s time. The Jeep services testing reported no issues. At that time they performed a realignment and sent me on my way. The most recent occurrence happened on Jan. 18, 2025. On this occasion the same Jeep services testing reported a possible problem with the tie rods. This vehicle was purchased in Jan 2021 and currently has about 25,500 miles. It has not been driven off road and has not been modified. Considering Jeep’s well documented issues of this nature, it does not seem that they have addressed the problems.

While cruising control is engaged, turning the steering wheel 5-10 degrees to the right will result in disruption of the cruise control and displaying a message "cruise control cancelled." This results in an abrupt deceleration during a turn that is unexpected and can create a safety hazard. Additionally, the illumination of steering wheel switches flickers with 5 degrees of right turn. This appears to be consistent with the findings of recall 15B, but my VIN is not included in the recall.

My 2021 jeep wrangler unlimited started shaking uncontrollably at highway speeds, and whenever I hit a bump in the road. I took it to a dealership which shows no active recalls. The dealership ran a diagnostic a d claims it is a faulty steering wheel damper. As this is an ongoing issue from previous jeep years, I was hoping you could investigate.

01/21/25 While driving on Interstate 64 at posted 70 mph suddenly experienced a complete shuddering of the vehicle. I was able to maintain forward direction with speed. Control on by “gripping” tightly with both hands and then braking quickly to shoulder and engaging 4 way flasher. I thought at first I must have hit something in the road or experienced a sudden tire blowout. But myself, spouse and brother-in-law exited the vehicle and could discern no apparent vehicle damage. No loose body trim / tires intact. I got down on the pavement and viewed the undercarriage and no loose parts were observed. Decided to drive it if possible. Vehicle started up fine and then accelerating to speed limit pulled up existing tire pressure and they were 36-37 psi. About 15 miles later now on I69 experienced the same sudden intense “shuddering “ of the vehicle. This time I braked quickly and let off the gas peddle and the wobble stopped. Immediately continued to Evansville Jeep dealer , reported the issue. They could not examine the vehicle immediately and though I expressed concern about driving the vehicle 50 miles back home I was told no loaner car available. I did make an appointment for 01/23/25 the earliest opening. The person handling the issue evidently discussed the issue with a technician and came back and stated it was a common Jeep issue and may need a “damper “ or repair to a damper. When asked if my extended warranty would cover the repair he wasn’t sure though I have less than 60XXX miles and purchased May 2021 with 100,000 miles extended warranty. I told we have a major trip planned soon and have concerns.
