Service 4wd light

I guess its my time to tell my "service 4wd" story for my 2011 JGC overland with 57K miles. This is about the 5th time we have used the four wheel drive aggressively since I have owned the car.

The other day we were on the beach and I always put the selector switch on sand/mud when going through the soft sand. There are some places that are real soft and I need to get going at a good clip to get through. My tires are new with lots tread, we don't lower the are pressure so they can dig in a lot (not the best situation for the beach) but I figure what the heck its a jeep it should go through any thing. When the tires spin some times I hear that noise like the anti lock brakes make when they engage (makes no sense). As we leave the cottage I see the dash lit up with two traction control lights and the SERV 4WD light. I never saw this before and at the time I could not think about it because I was trying to get through a tough spot and was thinking great another fault light. As we come off the hill we need to get through a real tough spot of soft sand (lights still on) nope Jeep just stops right in the middle of it, will can not move and only the rear tires turning, I'm stuck WTF! Its 9:00 at night, a major lighting storm and raining no one around. So I call my some to come tow us out which he did, I drove along the hard packed sand for about a half a mile and the lights went out, all seemed fine. Now I can't trust this car to do what is is suppose to be best at, what good is it? If it does it one more time, its good buy Jeep.

Sounds like user error to me.

How could that be possible the car is suppose to be made for this kind of stuff? From the looks of yours (looks nice) I doubt you drive it on the salty - sandy beach.

Re: Service 4wd light

My understanding is that there may be a TSB for this error situation after running on Sand for MY11-13. I had a similar error when I was on the beach a couple years ago. I didn't pursue it at the time since it is a very rare thing for me to do anything off-road and I only learned about there being a potential fix recently from reading a thread on another site.

You are 100% correct about me not taking my WK2 on the beach that's what my WJ is for... You have factory tires and don't want to air down ?? No a stock jeep is not made for that. If you want to be able to not air down get a lift and some much wider tires. I love pulling people like you out of messes you dig yourselves into.

I found the TSB for older jeeps (pre 2008) with this problem but can't find one for the 2011.. I called the dealer they don't seem to know of one specific for this vehicle either. Is there any other way to find the TSB?

Re: Service 4wd light

WOW - awesome that's great sounds like my problem exactly. My car was built in January of 2011 so the date works I'm not sure how to find the sales code DKA or DSF though. The other concern is this was written in July 2011 they might have already done this but then again if I never complained maybe not. Cat goes in the shop Thursday - thanks so much for your help, I will keep you updated.
