All gen5 HEVs have the spare tire screw hole. No gen5 PHEVs have it. Trim levels don't matter.

The only difference between the FWD and AWD screw holes is that the FWD version is a stand-alone part, while the AWD screw hole is part of the bracket that mounts/protects the rear motor HV connector.

Oh, the XLE pic above is an XLE AWD pic then, and I see the screw hole now, thanks.

I have installed one in my gen 4, and found the car dead when I went to use. it. I was able to resurected it with a full charger, but was quite annoyed at the fact it went dead. Isn't this the point of a maintainer? Could I b doing some thing wrong? Is it worth complaining to the dealer whom I bought it from and installed it?

Which maintainer brand. How many amps is it rated for ? How long do you leave the car sit before starting it ?
