#81 of 100 This one has my GM Service guys stumped...
Feb 19, 2010 (8:11 am)
Several times over the last few years my 2006 HHR LT has had a problem that the Chevrolet service department cannot correct. When driving or after just starting the car, it occasionally/randomly/infrequently chimes 3 times, the vehicle theft light on the dash lights up, all analog gauges perform repeated full sweeps, the information display cycles through bogus readings, the shifter clicks wildly, automatic shifting stops, engine stutters but keeps going and power steering goes out completely (this last one doesn't always happen). Brakes seem fine. This has happened about 6 or 7 times since I purchased the car used in July 2006. When it happens, I drive straight to the service department and leave it running for the technicians. They see the theft light on, and the lack of shifting, but by the time I get there the gauges seem to behave again. They have replaced various wiring but have yet to fix the issue. The last time it happened, the service department kept it for almost 3 weeks trying to repro the problem but couldnít so they gave it back unfixed.
It happened again last week and itís quite scary when it happens while on the highway. It's back at the service center but they're ready to give it back again without fixing it. I've contacted corporate to see if there's anything they can do, but beyond asking if I still have a warranty (no) they haven't been able to do much.
Anyone else have a similar experience or suggestions on what might be causing this?

Really nice mess of troubles you have there One thing I remember when the 06's came out was some people noticed fuses in underhood fuse box were not tightly seated, an easy thing to check and correct (and while there, perhaps a check of connections to fuse box would be in order). For whats happening inside of cabin, one thing that may be common is BCM which controls a bunch of stuff inside, loose connections, water intrusion from leaky sunroof can cause troubles in that area. (may as well check fuses inside cabin as well). Going back to big picture, a questionable level of electric suppply can reak havoc with electronics and engine stuff. Loose battery cable (at either end) or shaky condition (sometimes works, sometimes doesn't) alternater could cause this.

Thanks Ray80. This has been my little slice of fun for a while...
The Chevy service guy (their top electrical troubleshooter) did do a bunch of tests and replaced parts of the harness so I would think he already checked these things, but who knows. I'll ask when I pick up the car today - they still haven't found the problem but don't know what else to do. I'll also try poking around over the weekend to see if there's anything obvious.
Thanks for the ideas. If anyone happens to think of something else, please let me know. I like the car and would like to keep it, but only if I can get this issue solved.
#84 of 100 Headlights go out
Feb 24, 2010 (8:24 pm)
I have a 2006 HHR that I bought new Jan 2007. I have had very little trouble with it. A few problems were mentioned here in the blogs, but has anyone else had their headlights go out on then for a second or two? Mine has done this twice. I was driving at night and was turning right. I gave my right turn signal and brighted my lights so I could see the driveway better and the lights just went out for a second or two! My husband thought I did something screwy to it to make it happen then a few weeks later it did it to him!! We took it to our dealer and they had not heard of the problem and could not figure it out. Does anyone have any ideas? Also, we went to the mountains this weekend and our brakes now make the car shimmy. My husband thinks it might be cheap thin rotors. ??

Yup exact same problem with the lights sometimes, high beams on, turn right signal light on and everything goes out. It is most likely something in the turn signal/ light switch.

Didn't find anything obvious with the harness, battery checks out, and fuse box seems nice and tight.
The GM corporate folks have recommended that I get a VDR (Vehicle Data Recorder) installed from the dealership so that the next time all these issues happen, it will log a bunch of additional info about the current state of the car.
I'm hoping to get that done today and will keep everyone posted on what happens...

I'm going to call my dealer tomorrow and see if I can get it looked at again. I'll tell them to check the turn signal. Thanks for the suggestion and also letting me know I am not alone with this problem!!
#88 of 100 Heater fan problems
Apr 17, 2010 (1:39 pm)
This will be the second time I have had to change the heater fan speed control resistor.. I have found it on line for as little as $32. It is easy to replace, under the dash behind the glove box door. But I wonder why it fails at about 12 months.
There is also a squeal in the motor bearing. I guess that will be the next thing to replace, found it costs about $120 but I don't know how hard that will be to get out.
2006 HHR LT.

Without checking back to older posts in HHR or Cobalt, is that the problem where a cover that diverts water away that's under the plastic piece of the heater air intake leaks and lets water go down to where the resistor is? Others have replaced that or cobbled an effective fix.
I noticed it because I own a Cobalt which is similar to the HHR in design.
Edit: I found it in another topic with the HHR cluster.
Here's a llink to the whole cluster. You can subscribe to the whole thing and anytime someone posts you'll have it as an unread post
Good luck finding it. Sounds like the squeaking fan motor may be a result of a leak as well as the resistor unit.
Report back and tell us what you find.

I am relieved to find someone else out there with the same problem that I am having with my 2006 Chevy HHR LT.
Tim146- My car is doing the exact same thing as yours. Mine is actually back in the shop for the third time for this issue in the last year.
When I first got the car, within 3 months, I noticed that maybe after a minute or two of driving, when I came to a stop, the car would jerk forward, it would idle up and down, my foot was completely on the brake, but it acted as if it wanted to go forward. It would do this several times then stop. I immediately took it to the dealership where I bought it from. They installed one of those devices that records data from your car while it happens (you hit a red button on the device and it records for I believe 30 seconds) Everything came out clear.
This problem has continued for the last 3 years. Recently in the last year, when I first turn on the car, all of the gauge lights flicker, the 'power steering' and "low fuel" light flicker on and off, the shifter knob clicks wildly, the motor idles up and down, the temperature gauge, gas gauge and mph gauge float up and down at random trimes (the car is parked and e-brake is up, the car is not moving when this happens)
When all these lights are going off, I then try to shift into reverse and with each gear I go into, it makes a very loud "CLUNK" noise and the car jerks voilently. I drive it, then when I stop the car, it feels like its about to turn off completely, but at the last minute it turns back on again. As I'm driving and the transmission is switching through gears, the car "CLUNKS" again and jerks forward violently (almost like when you press the gas pedal too hard before letting out the clutch in a standard car and it jerks forward a couple of times) When I come to a stop, it feels like its about the shut off, then it turns back on within a quick second.
The first time, they told me it was a belt to my AC that causes it, they replaced it and $1200 later, the car acted up again 2 weeks later. That time, they kept my car for 2 weeks, they even had master techs from GM come to look at my car. They concluded that it was electrical and my computer. They replaced my computer, 'rebooted' the car.....4 months later I'm having the same issue. I dropped it off this morning (its so bad they know my name at the dealership ) So more testing will be done.
What can we do about this? There has to be more people out there with the same issue? At this point, I'm concerned about safely, or my car possibly shutting down completely as I'm driving. I plan to get rid of the car soon, with only 9 more months of payments, I hate to do it, but at this point, if this is going to be a 4-6 months issue (The car only has 40,000 miles on it) I can't afford to keep up with this.
