Stalling an automatic on an off road hill climb

It's not something that happens often, but it is possible to stall an automatic on an off road hill climb. In this situation you need to be able to react quickly to get into reverse gear to move back down the hill before getting into a slide and a rollover.

 

I was really surprised to find the Jeep JL Wrangler has this ridiculous feature for automatically engaging park when the engine rpm is zero. If this happens on a steep hill the JL auto transmission is likely to lock up when you least want it to. I can't believe that this 'feature' is in a Wrangler. I usually prefer automatic transmission for off roading but I would seriously think twice about off roading an automatic vehicle that behaves counter intuitively to other automatic off roaders. If the manual park override can be engaged before off roading and left in that mode, then this isn't a problem unless you are not aware of it. Perhaps Jeep can clarify if the automatic park override can be left engaged permanently.

I'm afraid I'm one of those people who occasionally reverses by looking behind through the open driver's door.  I had an Alfa Giulia press car for a while that would let you move a few metres before slamming it violently into Park.  I think it did the same if you started moving without the driver's seat belt engaged.

 

I imagine it's a series of FCA-wide features rolled out after poor Anton Yelchin ran himself over with his own Grand Cherokee, but while I found it unnecessarily annoying, I imagine the transmission found it even worse.

 

Vince, I know you favour the technique of removing your seat belt to lean out of the driver's window for a better view, something Jeep UK themselves used to teach.  In a JL, I imagine that is now impossible.

Really? Disengaging the seat belt might do more than just set off the chimes? Or will my butt lifting off the driver's seat shut off the engine like on my lawnmower?

Might do. Difficult to say what safety package we’ll get over here, but I reckon it’s safe to say door open = auto park. Sometimes buckling the seat belt behind you is enough to fool it, unless it’s backed up by an occupancy sensor. Guess we’ll find out in a couple of months.

Curiosity got to me so I read the manual.  With the doors off and the seat belt unbuckled, if you lift your butt off the seat it will automatically go into Park.  If your JL has keyless entry, it will even turn the engine off.  Apparently, it's happy to do this at any speed up to 12mph!

 

On the positive side, this behaviour is apparently disabled in 4Lo.

Wow! The parking pawl won't shear off when engaged at 11mph, that's amazing for such a heavy vehicle.

Jim asks :- "As I have never had a car with rear reversing cameras, just how easy, or difficult is it to reverse purely using the cameras? "

 

It's very easy with a little practice, and using the wing mirrors as well. On the WK2, you can see vertically down, which lets you know when you reach the edge of a marked bay (essential to avoid fines in some cities) or have 5cm clearance from a wall, etc. The wide angle lens lets you see cars coming from the side when backing out in a car park, too.

I'd really like one at the front when off road; I think new Land Cruisers have that feature.

 

The 'engage Park when the door opens' is really annoying, and I got the scraped bumpers to prove it when using a very tight private car park. The windows on every model since the ZJ are too high to be able to lean out and watch where the wheels are, at least for someone as short as me.

I found this Tazer JL gadget. It doesn't yet disable the automatic selection of park but it does a lot of other useful stuff that really should be end user customisable from the factory.

Acquire a spare seat belt buckle

 

This is exactly the sort of unintended consequence of badly thought out 'safety' modifications. I suspect many such modifications are more focused on reducing corporate liability / reputation damage than to actually prevent death or injury.

I'm with Steve on this ,coupled with  other issues too.

I think a lot  is down to lawyers and all their ridiculous litigation etc resulting in all this back protection which we all have to pay for!   Added to this , manufacturers are forced  to pander to motoring road 'testers' who are not in the world of most of us.  It wouldn't surprise me to find that many of these 'tests'  never happened. 

I'm planning to change my G.C. in the not too distant future. At my age I thought I''l have just one more new car.There are only a few  makes (including Jeep of course) that I would consider based upon personal experience of reliability and my needs. So I went out and started booking day test drives etc. I've changed my mind , based upon experience so far I will buy used!  Why, because I found the latest models have endless'safety features' gizmos and 'extras' that to me are unwanted and unnecessary . All of which come at my expense. I respect those who want them but object to being forced to have them when I don't.  A few examples power boot lids (I'm told cost approx £1000), self parking (£1500)  very low profile tyres(up to £400 each).  I don't need to ask why these are not optional.  The 'extras packages 'are crazy in my opinion!  I can't have the comfortable seats I do want unless  I have a panoramic sunroof which I definitely don't,  sort of thing!   Finally  I feel that some of the 'safety  features' breed  sleepy drivers who lack concentration because they are too reliant on tech.

Dinosaur, maybe!

Only just seen this thread.

I've stalled twice in my 2WD Auto Renegade. Going uphill offroading at last year's Jeep summer camp as I was trying to adjust my steering and then the next day when the rpm went too low for first gear. Guess what caused it?

Auto Stop/Start.

Unfortunately my battery was charged enough for that function to work. So it promptly switched off uphill when I braked and then as I couldn't accelerate immediately, slid downhill. 

It's such a pain and there is no option to disable this function completely. 

Electronic park brake does not engage when stalled and not having a handle to pull the emergency brake like other vehicles threw me off. Who thinks of looking for a button to engage the emergency brake?

Definitely going to ask dealer if the auto Stop/Start can be disabled.

PS. My e-brake is set to engage automatically when in Park however it will also engage when the door opens with the engine running and if you remove the seatbelt when in reverse, ie if you have been driving and decided to remove the seatbelt so you could reverse

Thanks frosty, looks like you're going to have fun with that project. I considered a respray but there's a lot of acreage on a GC to prep, spray and then there's a lacquer to finish off with to give its pearlescent finish - I decided it would be too expensive so gave it a T-Cut & keep it polished instead. My only worry is that it gets totalled in an accident. I'll lose the £10k I've spent on it and maybe get £500 from Adrian Flux. 

All the best and happy motoring with the TJ.

Chris

Hi.

Just to let you know that we can offer a fixed agreed value on pretty much any car as long as it's over 12 months only. If you'd like more details please feel free to drop me a line.

Regards,

Dan.

... i think A plan may also have it, i am sure they will advise. 

 

We have options for Agreed Value... only in Thatcham Branch (Specialist).

 

Our AV is done via the insurers and costs nothing, no charge, zilch! 🥳 As we do not use an additional external supplier for this.
But there are requirements to be met: 8 photos submitted, limited mileage, use of vehicle, where it's kept (varies on postcode) and that kind of thing - but if you meet the criteria then yes we can look at AV and it won't change your quote.

Thanks Carlie and Dan, but Dan I am aware of your AV and have considered it but I still don't think for a 12 month additional premium of £40 you'd pay me £10k if my motor was written off.

Because our AV is agreed with insurers  the value agreed is what it says on the tin so to speak (minus excess in a fault claim). 

- if its an additional product I'd always just advise reading their terms and conditions and checking reviews for that company etc 👍
