Five problems related to headlights have been reported for the 2012 Jeep Wrangler. The most recently reported issues are listed below.
Passenger side headlight failure. Repairs made to wiring, and replacement headlight installed. Lamp still only works intermittently. Affecting low light visibility. Potentially an issue with tipm which has lead to other electrical issues, such as transmission not engaging. Has caused engine failure, and control failure in other vehicles. Happens at any time, stationary, moving, fwd, reverse, turning, etc.
Exterior lights stopped working which includes headlights and directionals. I was driving and when I went to turn on my lights due to darkness they did not turn on. Tipm (fusebox) needs to be replaced according to mechanic. Told this is a common problem with this vehicle and will cost between $1100. 00 to $1200. 00 to replace.
The tipm unit went out, causing lots of issues. The issues we¿re aware of are: the doors wouldn't lock, shifter was stuck in park, radio/cd/bluetooth wouldn¿t work, and the front headlights wouldn't turn off leading to a complete drain of the battery. Thankfully, the vehicle was parked and this didn't happen while we were driving it (it could have been very dangerous if it did). It cost us $1100. 00 to replace the tipm unit, which was a huge financial burden on us, but even worse was that we had to go without the Jeep (one of our main means of transportation) for almost two months because there's a waiting list for the replacement part. We checked with 3 different repair shops just to be sure, and all said the same thing: 1. ) that there's a waiting list at least 40 people long for this tipm unit, and 2. ) that they've been seeing Jeep Wranglers left & right for this same exact problem, and there¿s a waiting list because the part can't even be manufactured quickly enough to keep up with the demand. I know the tipm unit has been recalled for Jeep cherokees, but why not Jeep Wrangler when this is clearly a major issue for it as well??.
Several problems occurred electronically with my Wrangler in the past 2 months. 1. Headlights turned on when I came out of the store 2. Check engine light came on (4cyl. Misfire) but cleared itself after 100 miles 3. While sitting idle at a red light, the dash warning light lit up and flickered as well as chimed for a minute. 4. While cruising on the interstate about 70mph, the Jeep shut off for a few seconds and turned back on before I was almost rear ended by the vehicle behind me.
The windshield wipers, directional signals, horn, steering wheel radio controls, headlights failed and rear back power window would not go up- this happened while driving in the rain.
