HHR Electrical/Lighting Questions



  • ray80ray80 Posts: 1,651
    Just a thought on the lighting. I see this question every year in various forums and for various vehicles as we get into fall and sun angle and brightness lowers as we move into fall /early winter. When in auto mode the sensor thinks its getting dark out and switchs from daytime running lights to regular headlights. For the IP and radio this means dimmer setting for night-time mode.
    The solution is to take it out of auto-mode (do without DRL's in daytime and remember to turn lights on at night), or, as the dealer did, turn dimmer switch on bright so the change is not so noticable. It can happen in sumer also if you enter a dark area for long enough (as in getting stuck under a underpass for a bit).

    Just got an 09 HHR (Lemon) :lemon: your comment about being concerned about safety and the possibility of the car shutting down completely, struck a note w/me. I am having that problem. :sick: The last instance was while on the interstate. I was lucky enough to be able to pull off to the shoulder but had I been in the inner lane, I'd have come to a complete stop and I shudder to think of the possibilities. This has happened several times and of course, no reason for loosing power or for the dash lights shutting off or the brakes not working (which caused me to rear end a car at the car wash) GMC opened a case file and has told me they will do what is necessary to find the cause of these the mean time can I hitch a ride? :lemon: :confuse:

    Hello hhr_lemon1,

    I'm glad that you made it safely through the most recent incident on the interstate you described! It looks as though you have a case going with us already, which is great. I wish you all the best during the repair process, and look forward to an update on how everything goes.

    Hi There, I bought the HHR LT2 in 12/06. A year later both one of the key fobs stopped working. I opened it up to replace the battery. I also noticed the metal clip to hold the battery in place lost its soldered point. Put in a new battery and used scotch tape to keep it in place. The piece of tape had be long enough to stick out of both sides when you snap the plastic cover back in place. Then you can trim off the excess tape. The same problem occurred with the second key fob and I did the same simple repair. Saved the ridiculouse quote for a new fob and programming it. Chevy should take ownership of a bad quality product and replace them free of charge to the customer!

    Hope this helps for a simple fix. Jerry

    Hi Sarah, In October of 2010, we started the drive from Portland OR, to Phoenix AZ. The 2006 HHR LT2 had a check Engine Light come on after about 5 miles, called the selling dealer service dept. Said to open the gas cap and screw it on tight. The engine light turned off and all looked ok. Drove about 250 miles to Grants Pass OR. Next morning check engine light came on. Did same thing with gas cap, no joy. Turned car off and on 3 times. Check Engine Light turned off. Drove over the pass into California going downhill and all the lights on the dash started flickering on and off, warning lights flickering on and off. Car shut itself off while on the freeway at 65 mph. No Power Steering. Fortunately, coasted off an exit. Called Redding CA Chevy Dealer and he said to come in, no appointment needed. After waiting 1/2 hour, Car started and cautiously drove to Redding Dealer. Explained the problem. Turned on the car and only check engine light came on. Turned it off and on. Check Engine light went out. Excellent Technician found CHEVY TSB for all the error codews that showed up, that said to check all electrical connections with computer processor modules, ECM, many others. Use some kind of "jelly" not sure what it was, on the connectors. The TSB said to do this with no guarantee it would fix the problem. There where about 12 error codes from the main diagnostic module. After 4 hours of unplugging and plugging all of the connectors, the problem seems to have been fixed. Have not had any electrical problems since. Loosing all power while on the freeway was extremely scarey and unsafe. I called Chevrolet and they conferenced the dealer and I was informed that Chevrolet would not reimburse me for the expense because only a diagnostic was performed in accordance with the TSB from Chevrolet. Since no part or fix was performed, I was out of luck. Safety did not concern the rep from Chevrolet and the case was closed. Since a TSB was issued, and its a known safety problem, why has Chevrolet not done something about this safety issue?! Jerry
