Selected complaints filed with NHTSA by 2008 Jeep Wrangler owners, lightly cleaned up (personal details are redacted by NHTSA).
Car was purchased 1 hour prior to incident from a dealership. Car was in idle and was shifted to drive and automatically accelerated rapidly without foot on gas pedal and breaks did not work when breaks were forcefully applied during the incident. The car crashed into a house deck and went off the cement pad and crashed into trees in the yard. Unable to remove key from ignition, had to be placed in neutral to remove key. We had the car for less than an hour after purchase. Damage was sustained to the deck and significant damage to car, air bags did not deploy. Claim was immediately filed with insurance.
The contact owns a 2008 Jeep Wrangler. The contact stated that the horn, alarm, windows, and windshield wipers spontaneously engaged. There were several unknown warning lights flashing. The vehicle was taken to the local dealer to be diagnosed. The contact was informed that the clockspring needed to be replaced. The vehicle was repaired; however, the failure recurred. The contact was then informed that the TIPM needed to be replaced. The manufacturer was notified if the failure, however, no additional assistance was provided. The approximate failure mileage was 125,000. The VIN was not available.
I was driving down the road in my 2008 wrangler and all of the sudden every light flashed on my dash board then it felt like I could not shift gears then smoke came pouring out of my air vents. I pulled over and got out realizing it was on fire. Climbed in to save my dog just before the fire got huge. My entire Jeep is gone.
The contact owns a 2008 Jeep Wrangler. The contact stated that while driving at various speeds or while the vehicle was parked, the horn would sound, the windshield wipers would engage while the windshield washer would spray washer fluid on the windshield, the doors would lock and unlock, and the headlights would turn on an off intermittently. The contact stated that the vehicle would lose electrical and motive power and become difficult to steer. The contact stated that the failure had occurred at least 30 times since owning the vehicle. The vehicle was taken to an independent mechanic and several dealers who were unable to diagnose and determine the cause of the failure. The contact stated that he was informed that this was a known issue with Jeep vehicles. …
My Jeep just intermittently started the crank no start issue and gave code PO5013, incorrect immobilizer key. After extensive research I have found many Jeep owners to have this same problem and also found that Chrysler has confirmed it is a built in problem. After taking my Jeep to to dealer and having my keys checked along with the starter and ignition cylinder lock it is the (WCM) wireless control module that is the culprit of the crank but no start issue. This is an extremely unsafe problem due to my vehicle shutting down while driving on top of the other various problems the wcm has caused. Directions say to reset the WCM by pulling the IOD fuse for 30 seconds and then replacing however this method no longer works.
April 22, 2025 my 2008 Jeep lost power. There was a sequence, where one warning light was followed by another, followed by a complete loss of power. I charged the battery, car started up, I drove to dealer (a 5-minute trip), and by my arrival the Jeep had again lost all power. Dealer checked the vehicle, and told me the battery and charging system were fine, but the ABS brake modulator was draining the power. They have not been able to get another modulator and the vehicle is still at the dealer (Crown Chrysler Jeep Dodge Ram Dublin, OH). Losing power precipitously presents a safety hazard.
This has happened on more than 1 occasion. Driving on the highway and I lose power, the Jeep slows way down, the accelerator pedal is dead, and the Electronic Throttle Control (ETC) light comes on. It does the same thing driving in town. Sometimes you can turn the vehicle off, wait a couple minutes, start it back up and it will be ok for a little bit. Sometimes it won't. I have replaced some parts, read forums, communicated with a dealer service department and it doesn't sound like there is a "fix" for this. This is very dangerous and someone could get seriously injured or killed.
While driving at speed, vehicle electrical went haywire. Headlights went on and off. Horn sounding on and off, Wipers and washers going on and off, HVAC blower on and off. Pulled over vehicle and turned off and removed key and it still remained running, all horn, lights, and wipers still going on and off. Opened hood, removed negative battery terminal, and with that, car still ran! Was several minutes and car finally shut itself off. Scary that the car went completely haywire and would not shut off, even with key out, and battery disconnected!
The TIPM shorts out then the wipers, start running, horn blares, windshield washer fluid sprays, lights flash. The only way to stop it is unhook the battery. This is so unsafe driving on the highway you cant see the road. I almost crashed trying to pull over. After doing some internet research this is so common. This should be a recall it is dangerous! I wont let my son drive it now.
The ABS computer brake module is bad in my jeep. It needs a replacement. Confirmed by Chrysler Jeep dealership. However, Chrysler does not offer a replacement module. ABS does not work on my vehicle. This is a huge safety issue and is common problem among this year Jeep. Chrysler shouldn't be allowed to NOT have a replacement OEM ABS module. Huge safety risk and lawsuit
