Failures after Jump Start

Failures after Jump Start
While on a trip, I accidentally left the lights on overnight and ran the battery completely flat. Got a jump start from AutoClub, and followed instructions in manual closely for jump, also disconnected aftermarket accessories and subwoofer capacitor. Now my tire pressure readout is blank, and the remote (key fob actuated) lock does not work. I reloaded the original programming from my HPTuners, with no change. Going to the dealer in a couple of weeks, but wondering if anything similar happened to anyone else?

Dealer fixed the problem, but it took more than an hour (no cost to me). It was actually pretty complicated to finally get the BCM to recognize the keyfob and tire TPM's. Manual says to jump start from the underhood terminals, but the dealer has had 3 HHR's that had this problem after jump-start, and recommends jumping at the battery instead (that is if you can get the deck lid up with that not-easy-to-use manual release). If you have never tried this release, I suggest you do it now, see https://www.chevyhhr.net/forums/show...manual+release
