2016 Grand Cherokee - Features & Changes

Re: New: 2015 Grand Cherokee High Altitude Edition

I'm guessing maybe 2016. When I checked the parts for the 2015 4x4 HA with air suspension...no dice. They are all SDA (normal) suspension...same as the Overland and Summit with air suspension. Part...

Well...I don't know what the sales demographics are but I kind of doubt they match your perception.

Well...it looks like it might be bad news for anyone hoping for a "sportier" air suspension in the HA models vs the standard Overland. I ran the build sheet of of one of the HA VINs coming in...

Re: 2016 Grand Cherokee - Features & Changes

Ditto. I specifically got an Overland instead of a Summit because I can't stand the trend of dark cave-like interiors and wanted a light interior.

Re: 2015 Jeep Grand Cherokee-transmission problem

It's either accidentally hitting a paddle, or in some cases may be a bad paddle switch which has an intermittent short (personally seen this...very annoying).

Re: Highest Oil Temp You Have Experienced ?

Highest Oil Temp You Have Experienced ?

235-240F is fine for a full synthetic motor oil. In all honesty, it's usually fine for a non-synthetic as well if it's not sustained for hours or days on end.
