Thumbs up WK2 Offroad

Had a great weekend in the Jeep last weekend. Spent Saturday on Stockton Beach and then Sunday drove up to Coxs river.

Few questions though im wondering if others have experienced?

With the Jeep in sand mode, going up some dunes it appeared once below a certain speed (like 10kmh ish) the traction control would intervene and really start to kill the power (even stalled the car once). Even happened in low range sand mode. I got around the issue by just driving faster and staying in high range for momentum, but just wondering if I can force traction control off completely?

On Sunday going down some steep sections, in low range using manual mode to engine brake, the car would upshift out of 3rd gear all the time, it would stay in 2nd and 4th but not 3rd. It would shift at about 2500rpm, anyone else experienced this?

Im going to take it in to dealer to check out but im waiting on some unrelated parts.

BTW, the car performs great most of the time, and the strange behavior i had could be easily worked around.

Re: WK2 Offroad

Re TC intervening at slow speed, are you keeping your foot on the accelerator when it happens? Or are you backing off?

Re: WK2 Offroad

Foot on the accelerator, all the way down.

A few times i turned off car and it reset to auto, then the traction control would be very intrusive. But set back to Sand and it would be ok.

Only time i experienced it was as the vehicle would be in very soft sand going up hill and rapidly losing momentum (ie when i need the power), a normal 4wd would just keep burying itself but the Jeep traction control would cut in and stall/stop the car.

Re: WK2 Offroad

Video should be fixed.

Appears the transmission TSB should fix my down shifting issues:

Re: WK2 Offroad

Video still won't work.

I've driven a fair bit on beaches including Stockton, and a couple of training days up and down some big dunes and low range has never been necessary. Low range in my book is for low speed crawling - sand driving is momentum and revs. Best technique I've found is that when the car feels to be bogging down just keep your foot on even position and the traction control sorts itself out and feeds more power as it sees fit. I've never felt like I was going to get stuck. It's a different technique to my old challenger where you needed to back off the power if it felt like it was going to wheel spin and dig in. The GC took some getting used to but I trust the tech now!

Re: WK2 Offroad

Agree - sand driving is all about momentum and revs. I got around a similar problem by using the paddles to select a lower gear to keep revs up.

Re: WK2 Offroad

I was there the week prior, the dunes arent as steep and high as 2yrs prior I was very disappointed. Lots of areas now fenced off. My overland performed effortlessly only time I would get stuck was forgetting to put it in sand mode. If I jumped in forgetting and it was left in auto it would bury itself but once sand was selected it crawled out. Never used the downhill descent as it was never needed. I did find the traction control doing odd sh it though but keep it floored and it sorted itself out.

Re: WK2 Offroad

20" tires down to 20psi although I should gave gone down to 14-16 think that would have been a little better

Re: WK2 Offroad

I was with nikjak on this one. Had a great time there.
On your matter, my car had a service and software update the week before I went here and all performed well. No issues with Sand mode apart from forgetting to turn it back on whenever I turned the car off!
