I received my Retractable Sunrider a few weeks ago, didn't apply for the Rebate.
Why ? The hassle getting it not worth the effort.
The Retractable Sunrider is great, overpriced, but works well.
Don't want to waste it ? Sell it to someone who can use it, stick with the manual- recommended oil for the 2.0T.
There are several reasons for doing this, as you will discover.
Well, the people that want old style TJs or CJs don't care about the enhanced Safety features of the JL, or the much improved fuel economy, easy to overlook.
My 2 Dr Sport JL, 2.0T, E-Torque, gets in the mid to high 20s on Regular gas, is fun to drive. Right now, a Keeper, despite the old TJs...
First off, the Posters Jeep is a 2.0, with E torque, so back to basics. The 12volt battery is charged from the 48v battery, so see if it is charging, and if the original battery is taking the charge. Does it test well under a load test ? These are things you can do, without involving a Dealer.
What oil and filter are you using,? Hopefully the recommended oil and filter for the 2.0 T you see in the manual. Hard to determine without this factor being taken into account.
I have 4dr seat covers on my 2 Dr, the upper trim handle is the only difference. The side air bag is the same, so if you don't have rear seat passengers, you are good to go.
The casting acts as protection for the camera. Sun, rain, dirt, without it.
I made a plastic shield for mine, on the set of alloys for my Sport. Easy to do, and well worth the effort.
