NHTSA Complaint #11474383 — 2009 CHEVROLET HHR

When driving my 2009 HHR the steering wheel shakes & vibrate at different intervals. Usually while slowing down to a stop & sometimes after during high speeds. Recently the noise it made was frightening. I had to use my emergency flashers & drive 50 mi per hr. on the freeway to arrive home safely. I took my car to Mark Chevrolet & reported it on 08/02/2021. The car's mileage was 133344. The car is not an everyday vehicle that is driven often. I received the car on 08/17/2021 after the steering column & shaft were replaced along with resurfacing front brake rotors & rear brake job. On August 18, 2021 while driving on the freeway I went to blow my horn at a hazardous situation & discovered none of the steering wheels controls were working, horn & etc. I immediately returned my car to Mark Chevrolet & reported their negligence & how they had risk my life to release the car without these functions working. They supposedly corrected the problem. On 07/05/2022 I had to return my car to Mark Chevrolet because I was experiencing the identical problem with my steering wheel vibrating & make noise. My cars mileage was only 137641 less than a year later with just 4,297 miles driven. They claimed to have tightened something up in the column & returned my car on 07/12/2022. As I was driving on 07/16/2022 again the steering wheel started vibrating & making strange loud noises. I felt so unsafe & tried to make it home safely driving at a reduced speed. I plan to return the car this week back to Mark Chevrolet and am asking for support to rectify this situation. I understand there was a recall on Chevrolet HHR 2009 Steering Electric Power Assist System. I don't know if this issue is related to that. I never received communication from General Motors stating that my vehicle was affected but apparently there is a problem. Please Help!
