We tried to start the Jeep at our home (street) and it would not start. But the electrical system started flickering. After some research, we decided to have the battery checked. The battery was used for 34 months of driving. Interstate battery tested it and it was low. We decided to buy a new one and installed it. Now the Jeep starts but there is a service shifter warning light and the gear shifter does not light up. We cannot put it into gear. There are numerous complaints on different Jeep forums. Some dealers cannot solve the issue, while other find that different harnesses are the problem. Our vehicle is out of warranty, and believe Jeep should initiate a recall to correct this problem for its customers.

When the vehicle is in reverse, whether stationary or moving, sometimes the parking assist grid lines do not show up at all on the screen that you are looking at which are supposed to help you when you are backing the vehicle up. The grid lines let you know how far to keep backing up, if you are going straight or at an angle, let you know when you should stop backing up, etc. This means you are not exactly sure when you should stop & sometimes you hit the curb behind you with your wheels or in my case, I hit our backyard fence. I also couldn't tell that I was as close to a parked car as I was or that I did not pull into a parking space straight. I've emailed Jeep several times over the past 2 years & joined several online blog groups & Jeep keeps telling us Jeep owners they will be putting out a uconnect upgrade which should fix it but we've been waiting over 2 years now & nothing has happened.

I have a push to start 2018 Jeep. The other day my car wouldn't start, battery died on it. It was fixed but then the ac/heat unit won't turn on at all. While looking for solutions I saw this issue was very common in 2018+ models and was wondering why there isn't recall on this if it's a electrical issue within the vehicle.

I was going around the corner and the steering wheel locked up making it to where I had to pull hard the other way just to unlock it. And when I first got this vehicle the windshield shattered within two months of owning this Jeep. And now the steering wheel is locking up and also my controls are not working on my steering wheel and the column in the middle ac heater heater all the controls.

While driving, the battery voltage light came on. We monitored the voltage and noted that it was dropping quickly from around 11.7 to a low point of about 8.9. when the voltage got that low, many different warning lights came on and the power steering went out. Vehicle was in motion when this happened, on a residential street going under 20 mph. It was immediately after a turn. Cause of issue is unknown. The day before, the battery voltage warning light had come on. I did some basic diagnostics and did not locate an issue with the battery connections or battery itself.

The wiring going to the steering column keeps shorting out making it so the horn, steering wheel electrical buttons and likely airbag stop working. The dealer says it is the clock spring. It has been going on since purchased with 12000 miles and replaced twice. At 22000 miles the dealer cannot keep it functional. I'm concerned that the lack of functional safety equipment could lead to injury or death. This also leads to loss of value if the manufacturer cannot provide a solution.

The 2018 Jeep Wrangler began having problems in Oct of 2019 with a racing engine and electrical issues, may of 2020 the car had severe electrical issues and the dealership could not find anything wrong.

When the car was returned to us the dealership said not to drive it very far. On July 23rd. The car went rogue in reverse at 60 miles an hour backwards. No pressure to the accelerator, it just took off, it has been determined that the braking system did not work. It was in our driveway.

The contact owns a 2018 Jeep Wrangler. The contact stated that she was never informed nor saw in the owners manual that the vehicle was equipped with two batteries. The contact was concerned because if the primary battery was disconnected the second battery would still provide electricity to the vehicle. The contact stated the secondary battery short circuited and the vehicle was not able to be started. The vehicle was taken to the napleton Chrysler Jeep Dodge Ram (1460 E osceola pkwy, kissimmee, fl 34744, 407-288-8243) to be diagnosed. The contact was informed that the batteries needed to be replaced to correctly diagnose the failure. The contact was informed that the manufacturer was contacted and informed of the failure. The contact was informed that the batteries were available for purchase at the dealer at a cost of $800 for both batteries or could be purchased at the local parts store. The failure mileage was 40,000.

On March 16th drove to work and parked car. Left work and got into car in parking lot. Upon trying to start the car we experienced multiple electrical issues as well as loss of power steering, traction control, stability control, engine start/stop failure, push start unresponsive. Car finally started although multiple lights remained on. Drove the car slowly to fca dealer closest to home and explained issues to service advisor tyler pennington. Dealer had car in service for approximately 3 weeks until today 4/3/2020. Picked up from service manager al begil. Mr. Begil explained that they never could physically find the source of the issues despite going through many wiring harnesses, modules, fuse boxes, etc. Communicated with fca engineering multiple times over the three weeks. Seems like it was engineering advised dealer to try something and if that doesn't work try let engineering know and then they would try something else. Our service adviser said that they had never seen anything like it. When I picked up the vehicle, I was told to drive around town slowly for several days in case power steering goes out again. Don't go on highway. Paperwork from dealer doesn't show any correction for concern. Called fca customer support upon arriving home. Customer support advised that my issues needed to be "escalated" and that someone would reach out to me on Monday or Tuesday. I now go through weekend without vehicle having to go to work every day. Fca customer service said they can't offer a loaner because we got car from dealer. Extremely unprofessional service department at dealer. Not much better from fca since I won't hear back for at least 3-4 days. Have notes of conversation with service manager that scared my wife and I to death. Just too much to write here.

Weld quality on frame are very questionable. When my Jeep twists while off-roading, it sounds like it wants to tear itself apart and the doors dont want to shut close when the vehicle is fully flexed. This doesn't happen to the newer 2019+ models with obvious better welds on frame. It gets annoying with all the crunching noise the body makes when I drive on uneven roads. Again, not seen on newer models. Also, the steering stabilizer was replaced and still my steering wheel start shaking when I drive on uneven roads. I have taken my Jeep to the dealer 4 times complaining about the radio and it keeps shutting off and volume freezing.

My 2018 Jeep jl has had non stop issues with the "death wobble" so much that I have had to park this vehicle and not drive it. It has been in three times for repairs, each time promised a fix would occur. Last week I was driving on the interstate between work and home, and I hit a regular uneven pavement one would drive over everyday, and the vehicle resonated so much that it pushed me into the left lane.. luckily no one was there but decided to park the vehicle till the next scheduled fix on 11/18. After receiving the vehicle back the instability is still there and resonates when going over any unevenness in roads. I have created a case with Jeep waive (case number 68188061) and called jim cogdill Dodge dealership in knoxville tn whom has repaired the front end the last three times. I was told on 11/22 that the dealership just got notice by a official Chrysler notification that the recall fix for the death wobble is not fixing the instability in the front end, and in some cases making it worse. They have been told to stop fixing the cars until a new part/fix is released by Chrysler. I now have a car that I cannot drive, purchase new just last year and have lost all trust in the safety of this car. I am looking for help to solution and help others whom are in my same situation. Additionally, my vehicle computer has messed up and is showing almost 1 million miles (999,999). This complaint is also part of my case as I cannot sale my vehicle, or be legal with the odometer in current status.

Steering wonders and is unresponsive at highway speeds requiring constant correction. This problem has nothing to do with the damper or track bar, as I have had these replaced, yet the problem persists (9/29/2019). I also, had the BCM body control module fail (7/11/2019) while in motion which caused the steering to lockup and the Jeep not respond (thankfully this was a low speed incident).
