“For the past 3 months I will be driving, in a pretty average way, not speeding or braking to hard, when all of the sudden my horn, alarm, wipers, windshield wiper fluid, and lights will go on and wont stop for up to 5 minutes, it has done this when the Jeep is stationary, in motion, or even without the key in the ignition”

“My 2008 Jeep wrangler would not start. It turns out that the wcm module failed. The replacement cost me $336.20. I know several other wrangler owners who have experienced the same part failing. Including one person where this part failed after only owning the car one week. Chrysler/Jeep will not acknowledge this as a problem with their vehicles.”

NHTSA complaint #10306794, filed 2010-02, 38,130 miles

“While driving, the horn, lights and wipers randomly go off and spray fluid everywhere. Nothing can be done to stop it and even turning the car off doesn't. It can be very dangerous to me and other drivers since they do not know why my horn is going off for minutes at a time. I don't want to be behind someone at an intersection with my horn and wipers going off. Looking online I can see that this is a common problem with this model and should be fixed before someone gets hurt.”

NHTSA complaint #11016543, filed 2017-08, 68,000 miles

“The clockspring on my 2008 left hand drive Jeep has broken causing my airbags to no longer function. I have a valid chrysler warranty until 85,000 miles. My Jeep is currently being serviced at the dealership to replace the broken clockspring which will cost $563. This part is not covered under my chrysler warranty which makes no sense at all. My warranty covers electrical components but the clock spring falls under safety components which are not covered. How safety components are not covered is way beyond me! …”

NHTSA complaint #10578320, filed 2014-04, 77,400 miles

“Got into the Jeep, started and placed into reverse, suddenly, without prior warning and randomly the horn starts going off, wiper fluid shooting out and the wipers going like crazy, air conditioner not working and radio blasting and going quiet. . Nothing you can do will make it stop, this will be a serious safety isssue if it happens when I am driving down the road. This makes it a problem to be driving this car, as you never know when the wipers and horn will start going crazy. I have read many posts that this could happen both when the vehicle is stationary and while driving. …”
