Key gets stuck / can not turn to off position and remove the key. If you can not remove the key within an hour, your battery will be depleted. There is an actuating rod in the shifter that pushes a micro switch that completes a circuit to pull a solenoid in the steering column to allow the ignition switch to be tuned to the off position (and remove the key) when in park. The plastic part in the shifter assembly breaks and allows the actuating rod to fall out. The fix for this is to replace the shifter assembly. $185 not including labor. The quick fix for this is there is a plastic plug on the under side of the steering column. Inside you have to feel for the end of that solenoid and depress it to release the key. GM tsb #06-07-30-004F acknowledges the common occurrence of this failure from 2006 to 2010 HHR, cobalt, and Pontiac G5. Although, if you are out of warranty, your dealer may be reluctant to fix this problem without cost. Tires, ball joints, brakes, what have you, fail and are, no doubt, a common occurrence. If fact that is to be expected. But the shifter in an automatic? I would think that the shifter in an automatic should last the lifetime of the car. Imo, they installed a poorly made part. To me, this is obvious since they are stating in that tsb, 2006 - 2010 shifter are expected to fall apart as mine did. I have a 1965 Plymouth belvedere, the oldest car in my possession, that the shifter never needed to be repaired. In fact I've never had an automatic shifter problem with any car. It was stated in a forum that GM should have considered a metal collar or ring around the plastic bit that holds that pin to reinforce it and this problem would have never become a nuisance. Also, when that pin falls out, the shift lever is free to move without pressing the shift button on the front of the shift lever, so it could accidentally be moved to another gear while driving, even reverse!! I guess that is not enough of a safety issue for GM to worry about.

I bought my car brand new and sometimes without warning the engine light comes on and you only have a few seconds to pull over before it shuts down. Sometimes the light comes on when I'm stopped at a red light and the whole car starts shaking as if you popped the clutch too fast, except this car is an automatic. I have found through trail and error if I start messing with the computer buttons on the steering wheel that changes the information that is displayed on the dash board it will sometimes reset itself and act okay. Other times I have to let it sit for over 20 minutes before it will start up again. There is no set time this occurs, sometimes it happens a few times a day and other times it will go a month without happening. It shuts down at various speeds. Sometimes I'm going 65 miles and hour and other times I'm going 20 mph. I have brought the car back to the dealer but they told me they can't fix it until they reenact the problem. Each time they have had the car they could not reenact the problem, yet they said they can see there is a problem when they read the computer. I paid $20,000 for this car and am scared to drive it. I can't drive on the highway for fear it will shut down again. I have to take the back roads to get around.

Could not remove key from ignition with gear selector in park. This condition was remedied by pushing the gear selector hard into park for a while. Then total failure came when no amount of pushing the gear selector hard into park would allow the key to be removed. I removed the gear shift cover and reached in and found a micro switch that when tripped allowed me to remove key. I called local dealer and Chevrolet factory toll free line and they did not say this was a known defect. I purchased replacement part # 25864102. I personally installed this and it fixed the problem. There is a steel pin in the gear selector plastic shift rod. The plastic is week and allowed the pin to drift approx 1/2" to left which would not allow the key removal micro switch to be tripped as it should be to allow the key to be removed from the ignition lock cylinder. I called Chevrolet back (tel # 1-866-790-5600) and they set up case # 71-781779261. They told me to take defective part to the dealer and they would contact the dealer to analyze the part for reason of failure. I took the part to the dealer service manager12/4/09. I called Chevrolet several weeks later and they said the dealer threw the part away since Chevrolet did not contact them promptly. I had ask for Chevrolet to refund the cost of the part only (no labor) but Chevrolet says they can't help since the part is now gone. I later searched on the internet www.mycarstats.com/ and found many cases like mine (apparently Chevy cobalt shares gear shift mechanism basic internal design style). I called Chevrolet back, they still deny this is a recurring problem. This is a safety problem because you have to leave your car with the key in it when the failure occurs. Apparently this may also drain the battery because all circuits are not shutoff when you cannot rotate the key far enough to remove the key. I fear that my replacement part may not last either. The car was ~ 48 mo old and ~ 47,000 miles when total failure occurred.

Heat/A/C switch only works on high. Brought to dealer in July or Aug of 2008. It was making a screeching noise on settings 3 &4, then it got very quiet and only worked on the highest setting. Was told it was a problem with the resistor for the fan switch. Was told they had the part and it would be replaced under warranty. In September of 2008 it happened again. As the weather in SC has been tolerable, I did not immediately take it back in for re-service, but did mention it the 2 times I has stopped into dealer for oil changes and 6000 mile service. Finally got a day off during the week, and did go to see about this again about the first week in May. Was told that it would cost me $300. I stated it was recurring and that it should have been fixed correctly the first time when they had to replace the resistor. Was told they only took it apart and blew out the system, what ever that means. My parents bought the same car, but a 2007 - same thing, they have not bothered to bring it in yet but I am sure they will get wailed with replacement cost as well. Has this happened to alot of other people out there? I am sort of thinking this is more than just a coincidence.

Purchased 2006 HHR new in 07/06. In 06/07 started the car and the electronic odometer, the speedometer, the tachometer, temperature gauge, oil pressure all were not registering. Nothing. Pulled over turned off the car. Started and nothing. Turned off the car an additional time and all lights and gauges started working. Took it to a local dealership/service. Could not replicate the issue. I have had in the shop on 7 different occasions for the same reason. It additionally will cause the digital clock on the radio to go out/flash, the air bag sensor to flash. They have replaced two electronic parts, one of them being the electronic control module. Around thanksgiving of 2008 I had started my car and all the lights and gauges again would not work. I took it to the dealership and the general manager was able to verify that this was occurring. They had the car for 10 days and replaced the electronic part. The car still does the same thing. No rhyme no reason. At night you can open a door, close it and see lights in the radio randomly flashing. I am concerned and awaiting the day that the car just dies while driving it. They have never been able to locate the issue and told me that I am the only one with any problems of this type.

Initially, I had intermittent problems with my 2006 Chevy HHR. The key switch wouldn't turn all the way off to release the key. I took it to the dealership while it was under warranty, and they informed me that they "couldn't make it do it" (for which they have a record). After about a year-and-a half of this intermittent problem, my key would not come out of the ignition at all. I was out of town, staying at a hotel and had to leave the key in the ignition overnight. I read my owners manual and found the hidden release button in the steering column. I took it back to the dealership, and because I am out of warranty, I have to pay for this repair that is due to poor craftsmanship. After researching this to see if was recalled, I have uncovered numerous Chevrolet HHR owners that have experienced the same problem, and it is a faulty shift linkage. This item needs to be on the recall list.

2006 Chevy HHR continues to have power steering go out during operation. This could be very dangerous under certain conditions. After reading several blogs, it appears that the cause is a defect in the eps (electrical power steering). It employs the body control module (BCM), power steering control module (pscm), torque module and various other systems. The system becomes corrupted and causes intermittent power steering failure. As stated above, if the system fails during certain driving conditions, (I.e. driving in curving, mountainous terrain) and system fails, this could cause very difficult steering and a traffic crash.

I need your help, 1st, computer broke, then 2nd gear shift, then 3rd sunroof, then 4th back door won't open-son can't get out, then 5th power steering, tried to replace power steering with a used one that we could afford, , now car is locked and won't crank, did what mechanic said to reprogram and it still doesn't work, GM replaced 1st computer, I paid for gears, tried to get GM to fix electric steering, said they would buy parts but not labor >1000, right before we tried to replace the power steering the crank started hanging, 06 Chevrolet HHR-no car, help, its so broke, hurt myself trying to drive it, and have been trying to get fixed for over 2 months, its a bomb, now I have no car to drive. GM states its over mileage, thought I bought all warranties, dealer went out of business, palm bay Chevrolet, fl, I need some help, multiple times have all but crashed related to can't hardly steer it, turn it, I think I've broke my shoulder with this thing. Now I catch a ride with 4 years to pay left on this car, help! its a hazard, I don't have goliaths strength any more!

First the gear shift would not come out of park without having to basically yank the handle with all of my strength. Then about two days later the keys would not come out of the ignition. In looking into this issue on other sites it has been stated that this is a common issue when any moisture (ex from a spill of cleaning) gets into the gear shifter. For this reason the dealership has installed a "temporary fix" being a quick release switch located under the steering wheel. I have looked for this switch since reading about it online and have not yet been able to locate it.

Fan stopped working and will not blow out heat. I took it to the dealer and they said it was an electrical problem with the blower motor. The car is 2 years old and I don't understand why an electrical problem would not be a manufacturing problem. The dealer will fix it for $527. I don't have that kind of money and I don't think this is a problem I should have to pay for. Why would a 2 year old car have an electrical problem. For sure it is a safety hazard. Besides that I live in Illinois and cannot drive in the winter without a heater. I would like for this problem to be covered by the manufacturer.

I bought the 2006 HHR in March 2007, in July I had the stabilizer links replaced, then in December I had to have the steering column replaced, in October 2008 I needed to have the struts replaced & now a week later I have to have the strut mounts replaced. Not only that, I had a leak from the heater case that leaked into my passenger side, I had the radio replaced & also my front & back bumper is loose which the dealer told me on the phone that is probably clips that have broken off. I was told because I live in Michigan, that the struts went bad sooner than anticipated. Also, although I had a car fax report on this car, this car has been in an accident that no one knew about. I am not very pleased with this car & its a shame to make a car payment on a car that I don't even like anymore due to the problems. I was told they would give me $9000.0 as trade in, but I had 13000 on it, so how do you get out of a car that you think should be recalled? I have been checking into the lemon law & I understand as long as you purchase the used car with the factory warranty still active, it's covered under the lemon law. But since the dealer wont do anything about it, I doubt GM will. I was told to wait till after the election, for the economy to get better, that doesn't mean they will reasonably get me out from under this junk of a car!

The contact owns a 2006 Chevrolet HHR. While driving 20 mph over a hole or dip in the road, the entire vehicle stalled and shut off. The weather was not a factor. The stalling occurred at least three times within one week. The vehicle cannot be restarted once it shut off. There were no warning indicators prior to the failure. The dealer does not know the cause of the failure or the remedy. The failure mileage was 53,000. The consumer stated the vehicle was having several issues with the cam sensor, wheels, a broken hub bearing, bent rotors and an issue with removing the key from the ignition, due to the shift cable not staying secured. The check engine light illuminated, the inside driver door handle would not open the door, the passenger side back would not stay secured. Updated 06/25/08

The contact owns a 2006 Chevrolet HHR. While driving through a car wash, the engine and traction control light illuminated and allowed the contact to remove the key from the ignition. As a result, the vehicle lost total power. He notified General Motors and aaa to jump start the vehicle. The owner's manual stated that this may occur if one were to drive through a puddle of water. It also stated that the engine may stall and cause the electrical system to collect water and moisture. General Motors stated that the failure was a manufacturer defect, but they did not know how to correct the failure. The dealer and manufacturer advised him to drive around in order to dry off the electrical system. The vehicle has not been repaired. The failure mileage was 15,000 and current mileage was 20,000.

Three times previously and again in the past week for the 4th time my 2006 Chevrolet HHR has been taken in to the dealers service department for the same problem-- which I believe is a very dangerous problem and which the service department can not identify. My 2006 HHR has the propensity to "turn itself off" while being driven on roads or highways. This tends to occur when crossing over small potholes, bumps or joints in the road. The first 2 times that the auto was taken in to service department they said no problem could be identified. The third time, in December 2006, they stated that there was a problem with a "ground" wire and they said that they had fixed the problem. However in the past months intermittently the car has again had episodes of "turning itself off" and these episodes have been increasing in frequency and have become extremely scary. On 11/22/07 while being driven on divided superhighways at speeds 55-65 mph, approximately 10 times after crossing over joints in the roadway or small potholes or bumps in the road the car totally turned itself off. The electrical system seemed to fail with headlights and dashboard lights going off, radio going off, and engine turning off completely). Luckily no one crashed into the car while it had turned itself off on the busy superhighway-- even though the car was still gliding forward on the highway without power. The car was taken 11/23/07 again (for the 4 the time in the past 2 years) to fitzgerald auto mall in frederick, Maryland to try to have them fix the problem. Today the service manager reported no problem with the car could be identified. I believe that this vehicle unsafe to drive since it unpredictably turns itself off. I believe there is some as yet unidentified electrical system problem that is very dangerous in this vehicle, and it is just a miracle that no one has been killed yet.

The outside temp indicator stopped working. The dealer replaced a "body control module" this caused the cruise control to stop working. 1 "electronic control module" was installed. Problem still existed. A second ECM was installed and the cruise once again works, however now my driving lights no longer work. It will be returned to the dealer for a time to try to get all the electronics to work as they should.

2006 HHR lt. History of ABS/brake/front end component failures and electronic malfunctions since purchase in winter of 2005. When applying brakes steering wheel shook hard from L to R and brakes grabbed/released. Dealer found rotors warped at less than 10K miles. Warranty repair/resurface. Problems continued: ABS engaged on dry pavement under 10 mph but would not engage at road speeds with brakes heavily applied. At same time, pedal went to floor. Ase certified GM mechanics told me this was impossible - until service manager test drove and concluded pedal goes to floor; car is unsafe to drive. Claim opened/resolved with GM. Dealer found defective wheel hub assembly (left) that caused ABS failure below 8K miles. (no accident) next failure occurred in the right wheel hub assembly and an accident resulted. GM and the dealer claim no defect but only error code is right front ABS failure with prior 7 pages history of ABS/brake/electronic problems (submitted to ins company and GM and in possession of the dealer). This failure resulted in an accident with substantial damage to the wheels/rims/undercarriage of the vehicle. GM and the dealer concluded - without bench testing the right wheel hub assembly - that there was no defect; however, the only error code recorded is an ABS failure (claim opened with GM). GM and dealer have called to see how the vehicle is doing - I declined to commit saying that I would be making a determination as to the vehicle's performance shortly. Good thing - the steering wheel shakes from left to right on application of the brakes and the brakes pulse as if the wheels are no longer round (grab and release). These are the same symptoms that occurred when the rotors when out of spec. It is my suspicion that the rotors have again gone out of spec and that the ABS/braking component failures are continuing with this vehicle. I am about to take the car to an independent mechanic for evaluation.

One day the radio would not change stations, I used the control on the steering wheel and radio turned up all the way and would not turn down until I pulled over and shut the car off. Took the car to dealer they tested and ordered a new radio. Not installed yet. A few days later the interior lights got real dim and would not get brighter unless I turned the auto lights off. This happened several times. About a week later, went out to start the car it would not start and the key got stuck in the ignition, called roadside assistance they jumped it and took it to dealer who said it was a loose ground. The radio quit working all together. Two days later it would not start again so I jumped it and it started. The radio started working as I was driving down the road. Four days later car would not start and we called roadside assistance again. They came and jumped it and towed it to dealer again where it is now.
