On January 2, 2023, at about 4:00 PM I encountered the ‘Death Wobble’ while driving in my 2020 Jeep Wrangler (2-door) VIN: [XXX], purchased from Dave Smith Motors, Kellogg, ID on about 7/17/2020. I was driving North on I-15 about 10 miles South of Nephi, UT. I was traveling in the left lane at Freeway speeds (75-80 mph) when the front of the vehicle commenced to shake violently. My first thought was that both front tires had blown, although I did not observe any obstacles on the wet driving lanes. My second thought was, how do I get out of these mess without causing a major accident on that very busy stretch of Freeway holiday traffic? I, of course, braked and pulled to the left in an attempt to avoid getting rear-ended and immediately encountered snow and ice on the left shoulder and then on the ground adjacent to the Freeway. I managed to get off the Freeway, but continued to fishtail, almost losing control on the snow and ice. Eventually the vehicle ended up in a sideways slide perpendicular to the Freeway with the front of the vehicle aimed at the Freeway and heavy TRAFFIC! At that point I had no control over the vehicle as it continued to slide sideways headed for a huge drainage ditch. Luckily, we stopped before the precipice. I scrambled out of the vehicle as soon as it stopped sliding to see what had happened to the front end of the Jeep. There was no obvious damage, the tires were not flat, and I couldn’t figure out what had happened. I have now received a NOTICE OF PROPOSED CLASS SETTLEMNT, that upon further research informs me that 2020 Jeep Wranglers have a manufacture defect that causes the ‘Death Wobble’ in precisely the conditions that existed with me. “…2020 Jeep Wranglers …have a front suspension steering damper defect that causes the steering wheel and front suspension of the vehicle to shake after contact with a bumpy road surface at highway speed.” I was not aware of the Manufacturer's defect.

Death Wobble yet again. Since September 2022 I have been experiencing unprecedented steering issues with my 2020 Jeep. This issue occurs out of random where it feels like my tires shake independently from each other making a rumbling noises when driving highway speeds. I am sure it has Death Wobble. Today is the lost current incident. When I was safe to be in a stopping point I told a family member about it. This family member told me that this is a big issue that should have a recall. They suggested for me to see for any recalls about it and if not start reporting whenever these death wobbles happen again. I looked and there are no recalls for my vehicle at this time. Vehicle has been reregistered in California and originally from Texas. I have no idea of where it was manufactured information due to this.

Driving on highway, 80 miles an hour in Southern Utah, three times I hit a normal bridge / road seam and the Jeep "Death Wobble" occurred. This is a well known thing amongst Jeep owners, but since I was a new owner I had no idea what was going on. After slowing down the wobble stopped. I thought I was going to crash. I am making an appointment with my local Jeep dealer to have it looked at.

We are experiencing the "jeep death wobble" intermittently, usually at speeds 60-70 mph only happens when hitting a bump, it shakes steering wheel violently until finally slowing down to 50-55 mph. Our jeep is all stock, with standard street tires and Never been off-road. Our Jeep has 28,000 miles and is still under warranty, although warranty ending March 2023. We have had it to dealership two times already, they replaced the steering stabilizer with a BDI brand after market stabilizer (experienced death wobble on way home from dealership after this was replaced) they also checked front end alignment which had no issues. They now want to try and change tires, which through my own research do not think this will help. I am now reaching out to another local Jeep Dealership to see if they will check it out.

2PE25014 · Instrument Panel Cluster (ipc) Failure
Opened Oct 23, 2025 · No close date supplied
Status: open (inferred from source dates) · Electrical System: Instrument Cluster/panel
The Office of Defects Investigations (ODI) is opening a Preliminary Evaluation on 2020 Model Year Jeep Gladiators and Wranglers involving a malfunctioning Instrument Panel Clusters (IPC) resulting in the loss of important vehicle metrics and other status information. ODI has received 89 Vehicle Owner Questionnaires (VOQs) alleging a complete or partial loss of the IPC display while driving. The subject vehicles' IPC display includes the speedometer, fuel gauge, engine temperature, turn signal indicators, warning light, and other gauges that are normally illuminated while the vehicle is in operation. Loss of the fuel gauge while driving may lead to an inability to determine the fuel level and result in a loss of motive power, and the loss of other safety-related information may impede a driver’s ability to take action to prevent a safety risk. Furthermore, an IPC that is suddenly not visible to the driver may divert the driver’s attention from the driving task, potentially causing a vehicle crash. ODI is opening this Preliminary Evaluation to evaluate the scope, severity and frequency of the alleged IPC malfunctions and to assess potential safety-related consequences. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov
EA23001 · High Pressure Fuel Pump Failure
Opened Mar 17, 2023 · No close date supplied
Status: open (inferred from source dates) · Fuel System, Diesel:delivery:fuel Pump
The Office of Defects Investigation (ODI) opened PE21-021 on October 14, 2021, to investigate incidents alleging a stall/loss of motive power as a result of high-pressure fuel pump failures in certain model year (MY) 2019-2020 Ram 2500, 3500, 4500, and 5500 heavy duty trucks equipped with 6.7L Cummins turbodiesel engines. During the investigation, ODI sought to determine if the related defect allegation was limited in scope to the recalled population. After review of information request response materials from both FCA and BMW, NHTSA determined that sufficient information to identify a comprehensive recall population could not be produced by FCA and BMW.During the investigation FCA filed recalls 22V406, 22E048, 22V767, and 22E087 which include vehicles not identified in the initial subject population by ODI. ODI also received recall 21V586, involving loss of motive power due to failed CP4 fuel pumps on certain BMW manufactured vehicles. An information request letter response received from BMW indicated that failed pumps on their vehicles were caused by an interaction between pump internal components and US market diesel fuel, leading to increased slip and eventual particle-generating wear surface. Additional work will be done to identify whether a similar root cause is associated with the FCA recalled population and if similar wear dynamics occur on pumps supplied to vehicle manufacturers other than those included in the recalled population.ODI has upgraded this investigation to an EA in order to 1) determine engineering specifications of internal pump components that are correlated with pump failure leading to loss of motive power or other safety related hazards, 2) identify vehicle populations equipped with alleged defective pump variants, 3) assess if vehicles equipped with alleged defective pump variants result in an unreasonable risk to motor vehicle safety and 4) gather and review any other relevant information related to high pressure fuel pump failure associated with the subject populations of recalls 21V586, 21V880, 21E094, 22V406, 22E048, 22V767, and 22E087.Review of the above information will allow NHTSA to confirm root cause and recall remedy viability, and identify and evaluate vehicle populations equipped with pump components that may pose an unreasonable risk to motor vehicle safety.The ODI reports cited above can be reviewed at: http://www-odi.nhtsa.dot.gov/owners/SearchNHTSAID using the following complaint identification numbers: 11257550, 11351441, 11361603, 11361616, 11365300, 11365426, 11365858, 11366401, 11372337, 11373793, 11374797, 11376793, 11377871, 11378173, 11384377, 11386063, 11387018, 11399710, 11402550, 11415339, 11418868, 11418870, 11427075, 11434276, 11436807, 11437226, 11437249, 11437273, 11437292, 11437294, 11437394, 11437399, 11437403, 11437405, 11437423, 11437528, 11437565, 11437579, 11437580, 11437590, 11437679, 11437744, 11437781, 11437842, 11437993, 11438006, 11438008, 11438121, 11438138, 11438155, 11438392, 11438629, 11439359, 11439879, 11440397, 11443030, 11446542, 11448163, 11453556, 11458918, 11460558, 11469337
