2018 Jeep Wrangler electrical complaints

In July 2021 our 19 year old daughter was driving our 2018 Rubicon on a trip 2 hours or so from home when all of the dash warning lights came on speedometer was lost . Panicked she asked us what to do? We told her to take it to the closest Jeep dealership (Ladd-Hanford DCJR) to see if the vehicle was safe to drive. She was told it just needed an oil change and it was safe to drive. About 10 days later my wife was driving the vehicle and the same thing happened. The vehicle was taken to our local dealer where they tried to diagnose, unable to duplicate the problem it was returned to us. We returned about 10 days later same lights coming on, this time power steering was lost. Dealership worked with Chrysler engineering and determined that the ABS module needed replaced. Work completed and Jeep was picked up. About 10 days later dash warning lights on, speedometer display out, power steering lost, back to dealership. Unable to look at at that time appointment made and returned. It is now September 30th we have cases opened with Chrysler and Mopar Warrantee. Vehicle is still at the dealership, diagnosis is now a $2000.00 chaffed wiring harness just outside the fuse box not covered by anybody. No guarantee that this will fix it. Neither will put anything in writing. I have tried to be patient, we need our vehicle. I do not feel that my family or others are safe when it pertains to this vehicle. I don't want it to be involved in an accident that could cause serious injury or death.
Stop/Start feature began intermittently working only in March of 2020. Stopped working completely in May. On July 31, 2020 it began functioning. Never worked again after that day. In March 2021 I had the vehicle serviced and advised the dealership it was not functioning. No tests were run and was advised I needed to drive the vehicle more to keep the auxiliary battery charged. On September 12, 2021, vehicle would not start after driving it most of the day. Had to jump start to get running. Would not start the next morning. On 9/13/21, jump started and driven to dealership. R/O Number 6085781/1. Installed BBAUX101AB battery due to Start/Stop battery failed. Stop/Start was not functioning upon leaving dealership. Did not function until 9/19/21 at 8:50am at an intersection. Disengaged the function by pressing the button on the dash. Vehicle shut down, displayed push brake to start. Vehicle put in park. Would not start. Had to use pull cord under gear shift to get in neutral and push out of roadway. Jump started to drive. Vehicle displayed "Stop Safely, vehicle will shut off soon." while driving down the street. Upon arrival, put in reverse to enter driveway, vehicle stopped reversing, felt like it was in neutral, vehicle engine began racing, instrument panel began flashing warnings, had to forcefully hold the brake, would not shift in to park or drive. All gear lights lit up on gearshift. Was afraid the vehicle was going to accelerate and crash. Passengers immediately abandoned the vehicle. Pushed to the start button and vehicle finally shut down. Warning flashing were: Service Electronic Stability Control, Service Power Steering, Service Airbag System, Service 4WD, Service Antilock Brake System, Passenger Airbag On (with no passenger). Instrument needles began moving up and down and would not stop. Opened door and needles ticked, blank screen and a ding. Did this for over an hour before all stopped. Vehicle completely dead. Will not jumpstart.
My Jeep Stalled on me in the middle of the street at Night. All of the lights dimmed out including my Emergency lights, I couldn’t put into Neutral or turn it on I had to get it towed Home. Both batteries replaced it turns on but stalls. Could be the alternator?
My 2018 wrangler accelerates when not on the gas pedal, and both the engine light and electronic throttle light comes on. My Jeep has been to the dealer 4 times for this issue and it still goes unfixed. It has been to an independent service center once, and they diagnosed the PCM (powertrain control module) as failing. This issue is very dangerous for myself and anyone else on the road as my jeep will accelerate at random.
I was in my car at a gas station and the car had shut down with ABS light, check engine light. The car would not start up with push to start. The shifter also was locked into place when the car eventually ended up starting. 5 mins later the car finally started up and all the of the warning lights/messages went away. I received an oil change + inspection from a dealership and nothing was found. This same problem happened again in a parking lot, (ABS, check engine, car not turning on) and I took my car to the dealership for service. They performed an inspection and I was told the ABS module needed to be replaced. About a week later I picked up my car from the dealership after they told me they fixed the issue and my car was good to go. THE SAME DAY, I had the same problem except this time it was significantly worse and extremely dangerous for myself and others. This time, WHILE driving my "serviced" vehicle, the ABS light, check engine light came on, dashboard stopped working, and the steering wheel also had locked while DRIVING and I was unable to turn. I was extremely terrified and I immediately pulled the car over. After multiple attempts to start the car (same issue as before: car would not start, ABS/check engine light) I promptly took the vehicle to the dealership again. The dealership is charging me again for another inspection, hours after their service? It seems that they are using this as an opportunity to make money, rather than actually fix the issue with the vehicle. This should not be about money, this is EXTREMELY DANGEROUS. The service the dealership has provided not only endangered my life, but the lives of others around me. I am extremely fortunate that this did not happen on the freeway. The dealer did not fix the problem, and in fact made the car dangerous with some of these new issues, the steering wheel locking up and the disabled dashboard. The part they replaced did not fix my car and put me, as well as others in a DANGEROUS situation.
My Jeeps steering wheel locked up while driving. It felt like the power steering lost all power. Also, multiple warning lights started to display and the speedometer stopped working.
Uconnect infotainment system frequent freezes and reboots, and this affects the backup camera display. Sometimes the backup camera guidelines disappear, sometimes the backup camera display shows a blue screen of death, sometimes it doesn't turn on when shifting to reverse, and sometimes the unit reboots itself or freezes. The reboots and freezes happen while in motion and are very distracting.
'service axel locking system' warnings light on dash. Occurred on highway in motion, driving straight forward.
While driving on the interstate at approximately 71mph, hit a bump vehicle started to violently shake. Slowing down did not fix the issue. I had to pull over and stop. Very scary feeling. Both batteries died out at approximately 39,000, first the main battery, then the auxiliary battery. Noise coming from behind the glove box when the vehicle is powered on or not. Clunking noise when taking off from a stop, or first take off. (dealer stated it was normal (yeah right)) passenger visor broken. Hardtop leaking in center front, causing the rearview mirror to ruin. (has been looked at by the dealership numerous times. Air conditioning when driving a long distance will sometimes blow out hot air on the passenger side. Coolant drained dye put in to detect leaks, no leaks. Still happening floorboards get extremely hot at times it feels like the heater is on.
Passenger side running light and side light stopped working. Changed the bulb and didn't fix the issue. Also found the back running light to work so know it is not a fuse. Appears to be fauly wiring or a bad ground. Has never been off road with this vehicle and only 42k miles.
The vehicle display and back up camera will freeze and not be usable often. It will freeze and not allow me to see my back up camera. It will also freeze and not allow me to turn the radio down or change a channel. This can happen while driving or while it is stationary.
Have brought my car in numerous times to jeep t correct issue. Back up camera doesn't always function. The screen is black when reversing and sometimes the screen works but without guiding lines. I cannot tell you how many times I have advised them of the issue and they have said they corrected it by resetting software or whatever but issue always comes back. I am writing to you this time because an incident that just occurred today put me over the edge. The screen was black while reversing and since my keep has a molar lift kit with 37 inch times I'm a bit high. I didn't not see or realize that someone standing behind me and I accidentally backed into them. More of a bump but none the less a scary situation. Someone could have gotten hurt. Nothing happened but I am concerned now. I'm also in law enforcement and I see accident all the time. I hope that jeep/chrysler corrects this issue before a tragedy happens. Back up cameras are federally mandated. So they should also be mandated to work effectively. Especially after there are so many complaints online about it. I purchased my vehicle in october of 2018 and from the beginning of my purchase I have had this issue and brought it to them to correct which they have tried but apparently failed. I cannot put a date on the bottom and correctly shows a time frame but know that is has been since october of 2018.
The jeep starts to shake while driving and it is hard to hold onto steering wheel. Feels like you have no control. The mileage odometer goes from 999,999 back to correct one. It is a brand new 2018. Can't get the steering part because it is on back order. We didn't even get a notice about recall. I am so blessed my daughter has not been in an accident going to and from college
While driving, the auto start/stop function will disable and a message on the dash pops up that says 'stop/start unavailable. Service start/stop' and a yellow a with an arrow around it will light up on the dash. This happens intermittently but happens every day. While at a red light, my jeep shut off completely while I was still in drive. The service message as previously stated appeared, along with the yellow a and arrow. I had to put my jeep into park and restart my engine. The system message and a continued to display. The vehicle has only shut down completely one time, how ever that still is a safety risk for myself and other drivers. Vehicle has been at the jeep dealership for roughly two weeks trying to determine what is wrong.
I keep having problems with my 2018 jeep wrangler and my check engine light came on then went away so today 30jan2021 I checked my system with a obd scanner and it popped up the code u0140 lost communication with the body control module.
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.
While my 16-year-old daughter and I were driving on the fl 528/beachline expressway the entire clutch pressure plate assembly exploded off my vehicle. Fluids drained and ignited. The entire vehicle was burned to ashes. The full accident investigation report is included in the upload.
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. The car was at the dealership for 5 days. In june the same electrical problems occurred and it was at the dealership for 6 days. 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.
Had issue earlier this year that cruise control did not work properly. It would not turn off when brake where applied. Now it does not even work. Vehicle had about 54,000 miles only when I tried to test it since the last incident.
Usb port 2. Fault malfunction with connected to USB cable.shown off the radio creating fuse/relay malfunction.
The jeep caught fire while driving normally yesterday on the i95 highway at normal speed.
Tl* 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.
The vehicle does not crank and have to wait 10 to 15 minutes for it to start.it happened four times in a week. There are lots of trends online with other jeep wrangler owner with the same problem. No diagnostic error when using obd scanner.
