    I have an ’06 that I bought a year ago from my sister in law to help her out of a bind. She claims to never have had a problem and if something came up she was at the dealership to rectify it and her stack of paperwork confirms it. It has 125k, is a 2.4 and Lt trim. My wife uses it as her primary car. I’ve replaced inside door handles….no biggy, they’re plastic, they break. Months ago my wife said the dash lights are going haywire. I drove it, nothing. Later she says it’s happening more and more. The lights go crazy, AC and radio shuts off and it steers hard. Oh, and key stuck but can stop engine. (Did the ignition recall). This week she called from work “it’s dead. No start, no lights, nothing”. I figure since the ‘puter is shutting things down, it’s prolly low voltage. Yes, the battery was shot – new battery (almost $200). Started the car. It ran for five minutes and shut down. Started again, die. Start again, die. Alternator? Another test with volt/ohm meter. I get no charging voltage back to battery so the ‘puter shuts down? Ok, new alterator ($125). What a horrible pain to get at, but today that task is complete. I start the motor and watch the meter. Good juice even with air on. I shift to reverse then into drive. Ok, no drop in voltage, sweet. No crazy light show on the dash. Man, I soo rock. I shift back to park, it dies. Start it back up, die. Start, die. Start, die. The car is still sitting in my wife’s Employer’s parking lot where I did all the “repairs” in between rain showers. Why doesn’t it go bad when it’s near the garage where all the tools are? Now I’m stumped and will have to pay for a tow and shop rates for diag and labor. Can’t wait to hear what they want for parts. Being retired and budgeting has it’s drawbacks. I haven’t even touched on the front end trouble we’re experiencing such as steering wheel wobble when braking hard. I inspected the brakes and it all appears in good shape (recent brake work performed according to sis in law’s receipts). I have replaced all four hub bearings and it still doing it.
    There are so many probs on this thread, has anyone got any solutions? I’ll try to be diligent and follow up with fixes.

      So far it has been learned that this 06 HHR, and very possibly many other models, have many grounding posts placed throughout the car’s unibody. Since the battery is in the rear under the spare tire, the negative post is no longer tied directly to the engine block like the “old days”. My mechanic researched the wiring schematic for this car and we found that many different functions are bundled and grounded at various locations. GM has replacement bolts you can order because the originals tend to rust and/or oxidize over time. A bad ground will play havoc with an electrical system by not completing a circuit thus not allowing certain functions to operate correctly. And since many of the problems we’re experiencing are bundled to common ground locations it makes sense the we will find the problem. Right? Each location was painstakingly checked and cleaned. All serial connections, wires, modular plugs and relays were inspected and tested. Seriously, we have talked with GM dealers, Buick dealers and they have no idea what do to look for next.
      BCM. Body Control Module.
      Can it be tested? No, not really. We know that the commands are being transmitted but the actions aren’t being carried out. An example would be that there are no injector codes stored and there is no pulse at the injector when there should be to keep the engine running. The ECM (Engine Control Module) gets a lot of commands from the BCM.
      My mechanic doesn’t have the expensive testing equipment that is usually reserved for dealers to plug in and the BCM but being a good mech and running a reputable shop, he knows someone that does. This process does NOT come cheap. The car is now in another shop and I’ve been contacted by the owner and he stated that he thinks we need to order a new BCM. You think? He says it’s getting commands but nothing is happening. Hell, I knew THAT much. I asked where he gets them and he answered “chevy”. His quote is just shy of $600 to acquire it, program it since it is specific to the car’s VIN, and install it. That doesn’t include the use of the “wonder machine” and his time thus far. Wow. Just wow.
      Please order the part and make the car whole, thank you very much I mutter through clenched teeth all the while trying to sound cordial. I doubt that it did.
      More later, I hope it’s good.

        Got the call to inform me that the car is done and ready to be picked up. With a shaky hand I swipe my credit card and the gal at the counter handed me my key. I have almost $1000 into this damn car so far. My wife and I go outside and she starts the car. It’s running!! Finally, a step in the right direction. I have my wife push all the buttons, turn every knob, operate all the functions she can find. It’s still running. Ok, lets roll. I’ll follow you home.
        This morning while my wife is driving to work the dash board lights went out and came back on and now the key fobs don’t work. Oh no, this feels very familiar.
        Tune in again to the continuing saga. More to come.

          had all those problems finally found somebody who diagnosed the situation as a simple bad ground to the computer he did not want to charge me took 5 minutes to fix after me spending hrs replacing sensors

      I have an 07 hhr I had the same problem with the keys it turned out to be a faulty neutral switch on the shifter, the whole shifter had to be replaced, a couple years later I got a recall notice on it and GM refunded my money. Currently I have no reverse due to getting stuck in a snow storm, but I guess at a 174,000 miles and only these two problems I can’t complain.

    I have a 2011 HHR bough it brand new with 11 miles on it. Before 20k miles I had a circuit short out and took it to the dealership for an under warranty repair. 25k I start having problems with the passenger side back window getting stuck in the halfway or fully down position and not closing. Took to dealership again who says I’m pressing the window button too much causing a temporary short. 41K miles and the passenger side window will not roll down from driver side controls. I get a check engine light that comes on out of the blue, take it to get a diagnostic, nothing wrong…now getting brake fluid/service traction message from dashboard.

    I have a 2009 Chevy HHR. It has 108k on it. Can anyone tell me how to fix my ground problem?? I thought my problem was because I was in a rear end collision??? About a year after that, every time I touch my brakes, my back windshield wiper would turn on!! It was driving me crazy, so I took out that fuse under the hood. Then my rear hatch would not open, I ordered a new latch and put it on, it works now. I asked my brother about it so he looked at it. He took one ground wire off the back hatch towards the middle (by the way, I had already taken the plastic covering off the inside the back hatch, it’s still off!) When he took that ground wire off, the back windshield wiper wouldn’t work at all, neither would the back taillights. I would like a fix for my car. I have also been having to replace the Intake Camshaft Position timing, also it read the oil control circuit malfunction??? It this car going to catch on fire??? Actually, it probably needs too!!!!

    Hi Armando
    So how did u fix the ground cable?

  • Juanita clark January 13, 2016 at 12:29 pm

    I have a 2008 HHR. I love my car. The main issue I have is in the Winter time my gear shift is stuck. It takes about 20 to 30 minutes the actually move. I have to literally let my car sit for that long for it to thaw out. It’s bad because sometimes I’m going to work and forget that I had to sit for an 1/2 hour more. What can I do about that?

    • rik January 17, 2016 at 9:10 pm

      theres a plug with wiring peoblem. you can bpass it its a switch under the shifter button press.

  • Cheryl January 16, 2016 at 12:12 pm

    Having the same problem. Went out this morning and my HHR wont let me out of park. Yes it’s 14 degrees out there but this should not be happening. Came back into the house and waiting for it to warm up….hopefully I’ll get to the store today. Can this be fixed?

    • Juanita clark January 20, 2016 at 4:16 pm

      I have been having this problem every since I had my car. Only in the Winter time though. It’s really annoying.

      • Juanita clark January 29, 2016 at 8:22 pm

        Cheryl I have had this problem since I bought it 6 years ago. Now I need a censor. I have had a lot done to this car. I didn’t realize it had been in a car accident until 2 years later. It was leaking antifreeze. I looked under the car and the paint was different colors.

  • Mary January 27, 2016 at 10:35 pm

    I have a 2008 hhr that I can not get unlocked. Why would anyone design a car with ony 1 key entry. There are 4 doors and back hatch. Key doesn’t work to unlock it.

  • Brittany January 30, 2016 at 4:36 pm

    I have an 07 hhr and the steering knuckle snapped, suspension on driver side twisted to hell and back. Car rolled 4 times… anyone else have suspension issues? Cause before 12/21/15 i had none to speak of. Never hit anything, no pot holes were in the road i was on. Suddenly car started jerking outta no where, ended with myself and my 4 year old flipping down the road into the side of a hill. Anyone have aome thoughts on this let me know.

    • Juanita clark February 3, 2016 at 5:35 pm

      I’m glad you guys are alright. I was having a steering problem, there was a loud click like it was going to snap or something. I went and got the steering column replaced last weekend. Now everytime I hit a bump it sounds weird. Back to the shop this weekend.
