Hi guys,

I'm new here and I'm seriously thinking of buying a new 2012 Jeep Cherokee Laredo X this summer.

I have a question though, is there any response lag when you hit the gas pedal?? Right now I have a Mazda CX-7 turbo, and when you floor the pedal there's a half a second lag time before the fuel injector kicks in.

I really hate this and if I had known (or payed closer attention) during the test drive I wouldnt have bought my Mazda.

Any help is appreciated, thanks

so you are looking at a 2012 grand cherokee laredo. i have driven a 2011 and there was no lag. honestly go test drive one

They don't make Cherokee's anymore.. Don't know much about the 2012 Grand Cherokee's.. Sorry.. What engine did you opt for? I think there were a few choices..

and of course WELCOME TO CF

Thanks.

And yeah, I'm talking about the Grand Cherokee Laredo X. The engine I want is the Pentastar 3.6L V6 engine automatic.

I just hope it doesnt have that annoying lag that my Mazda had (and also my Nissan pathfinder I owned before that had it to some extent).

Its annoying because if you need to accelerate quickly (like say you're stuck on a railway crossing and a train is coming), it will lag for about .5 seconds and not respond at all.

Highly, highly annoying!!

Everyone I've talk to with a 2012 JK(U) hasn't said anything about a problem with lag when hitting the gas.. So im gonna guess you should be OK.. Like others have said.. test drive one or two of them.. it's your best bet to find out for sure..

The throttle lag is because it has an electronic throttle instead of a cable linkage. Even worse than lag is a slow servo. My moms turbo Subaru has that, if I run it in first up to about 4000, build boost, then snap the throttle it accelerates about as hard as my Jeep from a standstill.

Gee oh Dee

I think that's turbo lag your talking about...

I don't know if a new grand cherokee has a responsive gas pedal or not but if not you could try one of these to fix it, but i don't see a listing for a 2012 model so that may be a problem.

Its a POS subaru. It has both. The throttle lag is bad enough that it has turbo-lag lag.

I plan on test driving one, its just that my nearest Cherokee dealer is 30 miles away, so I figured I'd ask on this forum first.

Yup, that sounds exactly like my Mazda. Its fricking dangerous as hell too, because if you have to pass another car the lag might just be the difference between accelerating out of trouble, or a car crash
He he....you know it

Interesting!

But on their website they say it only works on Cherokees from 2007 to 2011. Nothing regarding 2012's

Bingo...it's not the injectors. It's the turbo spooling up and kicking in. That's the lag youre talking about.

The last cherokee was made in 2001..

That's turbo lag...mixed with an electric gas pedal. So no a Cherokee won't do that.

Esco

Some non-turbo cars have it also. Its like a fuel injector lag of some sort.
My old Nissan Pathfinder had the same problem, although it was a bit less noticable
