Re: Caught On Fire

My Jeep is scheduled to get the fixes (brake and vanity mirror wiring fix) done in May. Yep, they were that backed up on this issue and I called them in January. It does worry me a bit about getting the recall done.

Does the fire start as a result of using the mirror? When the mirror is used, the light turns on and does this cause the short? Perhaps, like someone suggested above, it would be wise to just unplug the vanity mirror lighting.

My understanding is that the wiring can get pinched to the point of shorting. If that's the case then I'd think simply using the sun visor could cause that.

I had this recall done today. They did a nice job... only found two small fingerprints on the leading edge of the headliner by the rear view mirror. I consider that an indication that they actually did the repair... LOL.

They also ordered a new radio for me due to a chronic issue with SXM constantly displaying the "XM Service loading. Please wait..." message and rebooting of the radio. They updated the software, did the hard boot, had Sirius send a reconnect signal... nothing worked.

Thanks for the info. Had the visor recall performed two months ago. So far so good.

Re: Caught On Fire

You're welcome. I wasn't planning on doing it. Then I started imagining it starting on fire in the garage some night while I was asleep. That was enough to convince me to do it.

Total speculation, but given the description of the problem it sounds like a screw can pierce the wire insulation and cause the short (likely either to the grounded body or to another wire similarly pierced). This would explain why the vehicle has no danger of fire until after the headliner has been accessed and reassembled (which what is stated in the recall notice)... the problem is caused by service techs inadvertently driving a screw through a wire, and the "fix" is a plastic piece that moves the wires a bit off to the side to avoid screws being driven back in during reassembly of the headliner.

Now you can probably perceive how the "fix" could conceivably ironically cause the very problem it was meant to prevent: service techs have to pull down the headliner, loosen screws, move the wires, and drive the screws in again near these vulnerable wires that are now supposedly safely away from the screws.

In the case of grounding to body or to another pierced wire, then only deenergizing the circuit would prevent the resistance heating => potential ignition. Pulling the fuse is likely the safest course, but somehow I doubt the vanity mirrors are on a circuit branch by themselves... meaning you'd likely give up other functionality as well.

Re: Caught On Fire

I just had the same problem but I caught it before it caught on fire. The dealer did the recall last October. Last week it blew the M20 fuse and I lost all the controls on the steering wheel. I brought it back to the dealer and all they found was the blown fuse but could not find the short. I found it myself as you can see in the pictures. The wire harness was very warm as there is always power to this circuit.

Re: Caught On Fire

I have a 2012 Grand Cherokee. Here is a picture of the wire being pinched. As you can see the wire comes out from below the white disk and is pinched on top between the disk and the roof frame. When I pulled it out the white disk was melted and yellowed. I also felt the harness was warm as the vanity lights always have power.

Re: Caught On Fire

I own a 2011 Jeep GC WK2 and I also had a fire this week. I had the recall done earlier this year, and have a full Mopar lifetime warranty.

What was the result of the fire? Were your Jeeps fixed, or totaled? What did Jeep/Chrysler do for you during the time you couldn't drive your Jeeps?

Re: Caught On Fire

IMHO this is a very poor design.

The whole concept of having fuses, is that the fuse should blow before a wire is seriously overheated.
Whether it's a dead short, or just a high resistance one, the wiring should be heavy enough to handle the load until the fuse blows.
There is little point in having a fuse large enough to allow wiring to catch fire!


Does anyone know what size fuse is on this circuit? (I'll have to have a look myself.)
Maybe we can use a smaller fuse on the circuit to add a bit more protection.
I'd rather blow the fuse occasionally than have a fire, though maybe there is so much stuff on the circuit that it is impractical to do so??

Re: Caught On Fire

You're very lucky the fire department didn't put it out. Especially they way they put out house fires..... "The screen door is locked! Got the axe?... Good, chop a hole in the roof. We'll get water on it from above!"

It's worse than you think... I'm pretty sure there is no fuse! People have posted that info. I would cut and cap all of them if I knew how. I never use sunroof anyway. As i posted before my neighbor had a fire a week after his recall.. So I'm not having it done.
