The engine began a random misfire problem, P0300 code. I got the throttle body changed out, now the car revs higher every time I start it. It gives itself fuel in reverse and drive, with no help from the gas pedal. It is unsafe.

I was driving down the interstate at about 70 mph, when I began to get the messages service ESC ESC off, traction control of, engine reduced power and not to mention all my lights lit up like a christmas tree. Also when all of this started to happen my vehicle jerks reduced speed drastically and was shaking vigorously I hurry up and exited the interstate and turned off my vehicle I waited a few minutes and the vehicle started right up 3 miles or so down the road the exact same thing happened only this time I was turning unto a busy intersection and I was left stranded in the middle of the street because the car would not budge I had to end up getting it towed. This is something that it's very dangerous and if I would have had my kids with me I wouldn't be as calm as I am now. I am livid and outraged as to why this has not been recalled. How many complaints does it take until this type of situation gets addressed the way it needs to? now haven't spent over $600 my problem still exists but only now my vehicle is inoperable and parked. Please someone give us answers the correct answers the answers we've all been searching for and do the right thing.

My 2011 HHR has started acting up by throwing out the reduced engine power light, ESC light and service traction light. This will happen when in park(when warning up the vehicle) and when im driving. It seems to happen more in cold weather. When it happens it reduces the speed down to 25mph and lurches forward and sounds horrible! I have had this happen when driving down a highway and the interstate (luckily I was in the right lane and able to get the shoulder safely. There is no warning when it is about to happen. It also will do it while stopped waiting for a stop light to change. It will throw on the check engine light and we have checked the codes and changed what it said needed change but that did not work. From what I have looked up it looks like people are having all sorts of issues with this but no one has found a solution. There needs to be a solution because spending hundreds of dollars for it not to fix it is not right.

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.

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 road.it appears that this is happening with numerous vehicles from around that year.

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.
