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. Keep in mind I live in MN and have done NO off-roading. Someone is going to crash of these issues do not get fixed

I spent extra money to get a Jeep Wrangler 4xe, and for over a month now it has been under recall 89a. I have to pay for gas and park far away from everyone and everything, as though that is even possible. If I don’t and my new, expensive vehicle catches fire I will somehow be liable if someone chooses to park next to me, or if my driveway isn’t long enough and the fire spreads. There is no fix or compensation in sight and I am angry that this has happened to the car that I used to love.

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

Owners are advised not to recharge their vehicles and to park outside and away from structures until they are repaired. There are a few reasons why this should be a NON-Driveable recall. 1. The recall involves risk of fire and injury to those in or near the car or property. 2. It is a significant hardship to have to continuously park a car outside of the garage due to extreme cold. Often times homes/apartment buildings simply do not have outdoor parking. 3. It is also extremely challenging to find a place to park the car away from others when driving about town. How does one do that in busy parking lots and parking structures? This would be difficult in any state but far more pronounced in states with cold climates where the vast majority of parking areas are busy and often covered or enclosed. 4.If something catastrophic happened to the Hybrid battery system where the Hybrid system didn't work, you would essentially be stranded. This seems counterintuitive with a separate gas powertrain and separate Hybrid powertrain. 0% is still about 15% general operating condition for the electric assist. There is always some type of regen working to maintain that SOC. That is unacceptable for a dealership to treat this as it is and not notified the customers when or what could be done.

Recall (B9A) has been out since November of 2023. The recall states "An internally failed HV battery could lead to a vehicle fire with the ignition on or off. A vehicle fire can result in increased risk of occupant injury and/or injury to persons outside the vehicle, as well as property damage." As of today, no 'remedy' is available. In the mean time, can't charge the car. Driving the car would seem to be 'unwise' as the risk seems to be with the 'ignition on or off'. Can't park the car in my garage. Can't drive it to work as my employer doesn't want the liability should an issue arise. Been waiting patiently for a remedy - so far nothing but static.

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?

- Auto stop / start "feature" failed at restarting the engine. - At an intersection, waiting to turn left and for a gap in oncoming traffic, the auto stop feature engaged. Upon an opportunity to proceed, the vehicle did not restart and left me stranded with traffic on coming. Luckily, the approaching vehicle was able to stop - else I would of been t-boned, hitting the passenger side with my wife in the seat. - The only warning was barely noticeable - just to "SHIFT TO PARK" - As a result, I will be purchasing an after market component to override this "feature" I will never be stranded or put in harms way for political reasons again.

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.
