Mine has an issue with the TPMS. After about 25-30 mins at freeway speeds, 105km/h or higher, the TPMS light comes up flashing for over a minute, and then goes solid. According to wk2jeeps, this indicates a fault. Once you drop below 80km/h it goes away after about a minute. It last happened in September after a return trip on the M4, and can be replicated pretty reliably.

As it's in for its 10000km service next week, I was thinking about taking it out on the weekend down the M5 to trigger it again. Though if it's keeping errors, then there should be 4 instances of the problem recorded.

This is a base system on a Laredo, so no other hints as to which wheel is suspect. Pressures are correct each time it happens and it never occurs at normal speeds.
That issue appears to be related to the tyres heating and therefore the pressures are exceding the tolerances.
What pressures are you running?
I am running 38psi, and noticed when coming back from Vic a few days ago when the ambient temp was 43c, my pressures where over 42psi while driving at 110kph. My TPMS never showed any alerts at that temp.

Re: Grand Cherokee + sand = FAIL

They're only supposed to alert for low pressure according to the detail on wk2jeeps.

However I did think about over pressure as well the first time it occured, as I was running 36 cold. They were at 40 when I stopped to see what was going on. Which is not particularly high for a hot tyre, so dropped them back to 38 hot. It re-occured as soon as I got back over 105km/h.

The second trip that this happened, I had they tyres at the standard 33 psi cold. It happened again after about 25 mins at 110km/h.

The only constant in all this is over 105km/h for more than 25 minutes and it's a fault warning that gets generated, rather than a low pressure warning. There must be a sensor that isnt handling the rotation at that speed terribly well.

Anyway - sorry about hijacking the thread,guys. Back to the sand ....

I have the same problem. It happened to me 2 times, once during a slow turn and today at 80km/h. I am running 33 psi cold. checked all tyres after the fault and pressure was 36psi. I am suspecting it is a one or more TPMS sensors faulty/intermittent. A remote possibility is some external RF intefernace at 433MHz causing malfunction in TPMS.

Anyone got a recommendation for a good Tyre pressure gauge?

I still haven't had mine on the beach so haven't had the issue before, wanted the install for peace of mind (or if they said mine was clear then it would at least give me a legal argument if it ended up with the fishes).

Install of the module was completed today, first one the dealership had done. There is still a software flash that Jeep are apparently working on, in the meantime the abs light will still flash in heavy driving on soft sand but doesn't actually effect the abs.

Can't wait to test it out now, just need to get some time to get my recovery hook installed (eBay purchase) and then I'm away.

Re: Grand Cherokee + sand = FAIL

Hi Tooves,

Is your GC equipped with quadralift or the normal suspension?

Thanks Tooves. The reason I asked because somewhere along the line was a statement that this fix was only for QL equipped GC's.

Mine is in next week for it's 10000 and I have already flagged that I want this looked at as it will be doing sand and desert work trips this year.

I was originally told by my service manager that they had fix for QL vehicles only, but then after that he back flipped and said he had nothing for my QL equipped GC anyway. In my opinion I reckon it has the potential to affect any wk2 GC (unless they have been applying the software fix to most recently manufactured, but if that were the case I would also expect a TSB).
If I were you Savvas, I would not rely on the service dept giving you the fix (there is no TSB). I would bet money they will come back to you and say they have nothing. Contact Chrysler in advance and get the module lined up and ready to be fitted when you have your service done.

After 2 weeks of to and fro with the HQ and service manager I have just been told that the engineers at the service center haven't been able to follow the instructions and basically lost. I was also told that the senior engineer has resigned and walked off.

HQ will call me tomorrow and request me take the vehicle to another service center.

What a nightmare.

Re: Grand Cherokee + sand = FAIL

For the benefit of everyone it might be worth stating which service centres have actually been able to do this right, and which ones haven't.

So the guys who have had this done successfully, which dealer was it?

live_life_tb ... I reckon that service centre has bigger problems than this.

Re: Grand Cherokee + sand = FAIL

Mine was done at Salters at Springwood (Brisbane, QLD), althought it is worth noting that I haven't field tested it yet.
