Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Ignition recall, the switch has been replaced twice. I am still having issues when leaving key in ignition in the off position, all dash lights flash and a lot of clicking noise and will all lock doors. The service air bag light will come on, when you turn it off and restart car it goes out. I took it to the dealership and was told that they could not find the switch defective and they would not replace it, or check into the matter with out charging me a service fee of several hundred dollars. I travel long distances, and concerned about my safety, and other that could be involved in an accident.

The contact owns a 2011 Chevrolet HHR. While driving 30 mph, the vehicle stalled and the electronic stability control warning light illuminated. The vehicle was towed to the dealer. The technician was unable to diagnose the failure. The contact mentioned that the failure recurred on four different occasions. The vehicle was taken back to the dealer who, in turn, contacted the manufacturer in order to have an investigator inspect the vehicle. The investigator was unable to determine the cause of the failure. The manufacturer was made aware of the failure. The vehicle was not repaired. The failure mileage was unknown.

Driving along, 'low engine power' light came on (along with other errors, something about traction, something ESC, engine chugging; car slows down to about 10 mph and won't accelerate; after turning car off, waiting a few minutes, car started again (but check engine light stayed on); this has actually happened to me 3 times in the past 3 weeks (I don't recall the exact dates) - I thought it might be from the extreme cold (close to 0 or below) - but today it is 31 degrees and happened again. I'm glad I wasn't on the expressway! fortunately it happened at moderate speed and I was in a place I could safely pull off the side of the appears that this is happening with numerous vehicles from around that year.

I was driving a freeway speeds when the engine suddenly went into limp home mode. I received the following dash indications - service ESC, traction off, reduced engine power. Upon further inspection we found a failed accelerator position sensor and we had the following trouble codes stored in the computer: P2135 Chevrolet - throttle/pedal position sensor/switch 'a'/'B' voltage correlation replaced the accelerator position sensor and gas pedal assembly, at this point the car seems fine. I have the failed part.

I was driving 55mph when my reduced power light came on and my car wouldn't go over 40 mph with my gas pedal all the way to the floor. The next day pulled the battery cable and let it reset. Drove fine for 3 miles and then did the same thing. Reduced power came on and wouldn't go over 40mph. Very dangerous when driving on the highway and your car suddenly slows down and there are cars behind you and you can't get over!

While driving on dry even pavement the ESC light/system kicked in on my 2011 HHR causing loss of control of the throttle and brakes. Luckily, no other cars or pedestrians were near me or there could have been an accident. The car was undriveable until the ignition this turned completely off and on again. I had it checked and no error codes were stored on the ECM/BCM. This is a very dangerous problem!! this is the second time it happened to me and I may not be so lucky the next time!

2011 Chevrolet HHR. Consumer writes in regards to vehicle acceleration issues. The consumer stated while driving, she noticed the vehicle exhibit a boost/jerk type movement, and it made a strange noise. When she took the vehicle to the dealer, she was informed the problem was a spark plug and they fixed it. However, one night while driving, the vehicle once again exhibited the same boost/jerk movement, as if she suddenly hit the brake, as the vehicle was losing speed, until it shut down completely. She was able to pull over, turn the vehicle off, and re-started it again with no problem. A month later, the same thing happened, only that time, the electronic stability control light started blinking, followed by a strange noise. The electronic stability control light illuminated again in May 2014.

Driving on I-25 on the West side of eisenhower pass & the engine shut off leaving me with no power steering or breaks. I was able to thread my vehicle through semis & spring break ski traffic to the side of the road to a runaway semi lane. The car restarted after I stopped shaking & was able to make it home to basalt. 2 months later the same thing happened on co hwy 82 on a straight away between carbondale & glenwood springs. I was able to safely maneuver the car to the side of the road. Both times I checked the internet for recall information finding nothing. The recent media attention alerted me to the current recall & have called my dealership & made an appointment for the ignition switch to be replaced.
