New member here, my wife's HHR is having this issue where the speedometer will randomly spike, stopped or driving, but no associated RPM spike. Several times in the last few weeks, her car has simply stalled when she comes to a stop, it'll turn back over but the stalling is making her worried. I'm thinking somewhere between an electrical issue or maybe the computer, no check engine light or anything but I'm rather stumped on what way I need to look. It's a 2011 LT I believe, over 100k miles.

 

Has the ignition switch recall been done? Battery checked? https://www.chevyhhr.net/forums/gm-r...-status-50716/

 

X2^^^^^ have the battery load tested, it could be on it’s way out!

 

X3^^^^^^ Hot weather is a battery killer.
