Tl* the contact owns a 2008 chevrolet impala. While driving various speeds and making a turn in any direction, a loud knocking noise was heard coming from the front driver side of the vehicle. The contact stated that the emission warning indicator illuminated, but could have been caused by the fuel cap. The vehicle was taken to an independent mechanic where it was diagnosed with a failure in the lower driver side control arm, which needed replacement. The vehicle was not repaired. The dealer and manufacturer were not made aware of the failure. The contact found the federal safety agency campaign number: 12v377000 (suspension), which only included chevrolet impala police vehicles. The failure mileage was approximately 102,000.

The air conditioning actuators goes bad to a point where a knocking noise will start to come from inside the dashboard. This eventually will kill the electrical system and cause the car to cut off completely, even while driving.

This vehicle has been recalled due to air bags, and in a year no one has been able to get the repairs done to the vehicle. But furthermore the car has several other mechanical issues that I am showing as a trend with impalas being that my sister and cousin have one also in different years, the car makes a ticking noise when the air or heat is turned on the passenger side delivers opposite temp as the driver so if air is on the passenger will deliver heat and vice versa. If the car goes over a speed bump the engine reduces power and service stabilitrak appears across the lighting as well as the car dropping out of gear if I go over any bump. This is very dangerous especially being that my children and I were in this car and it decided to do this on the interstate at night in 70 MPH traffic. After doing research on the vehicle I am showing that I am not the only person with all of these problems listed, and it bothers me that none of these issues have been recalled just as the air bags were even though I think the recall, is just to save face because no one is actually doing the work to get them fixed. At first I thought these things were just mechanical problems with age of car but after research these are issues that are in cars made in this time frame and warrants a recall for the safety of consumers.

2006-2009 chevrolet impala ss ticking noise, engine misfire and/or ses light. This may be the result of an afm (active fuel management for displacement-on-demand) lifter that unlocks as soon as the engine is started or one that is mechanically collapsed/stuck. If an afm lifter unlocks as soon as the engine is started, a ses light and dtc p0300 will be experienced with engine misfires on cylinder 1, 4, 6 or 7 but it is unlikely that any noise will be experienced. If an afm lifter is mechanically collapsed/stuck, a consistent valvetrain tick noise, ses light and dtc p0300 will be experienced with engine misfires on cylinder 1, 4, 6 or 7.

Reduced engine power message, faulty back door locks, heating actuator repairs. This is a revised complaint to one I also made for just the reduced engine power message. After reading numerous complaints on here I have found that my car has several of the issues not just reduced engine power. I am most concerned with the car cutting out while driving due to the reduced engine power however we also have locks that don't open/lock with remote which has been going on for the last 3 years and since last winter heater only blows cold air until you accelerate the car. This month we had car repaired for a knocking noise coming from under glove box while car was running or shut off. Mechanic diagnosed as a new actuator and did repair. This however did not repair the blowing of cold air and also this is when the reduced engine power warning started. I am a former gmac employee and have had gm vehicles for the last 15 years. I am so disappointed that there are so many problems with this make/model and that gm has not issued a recall on these.

I bought the car in 2009 and it had given me problems since I bought it. A week after I bought the car, the gas sensors went bad, the door handle came off and the locks wouldn't work. That was a $1000 bill. The tire sensors went bad and now the locks are going bad again. Ever since then, the blend door actuator, which regulates the heat or recirculating air has consistently gone bad. I have replaced it three times so far and two of the actuators have gone bad again. It makes a loud knocking sound under the dash whether the car is running or not. It also happens when I'm driving. I have called chevy so many times, I remembered the script they read to you. They never helped. It is a $200 repair bill every time it is repaired. I tried to let it burn itself out and it lasted over a year. I was told by a mechanic that it is a problem on 2004-2008 impalas but they never recalled it. It also causes the air to blow cold in the winter. Why wasn't a recall done on these vehicles.

As I was driving, I got a notification on my dashboard that read "engine power reduced service traction control". I continued to drive to my destination or somewhere I could safely pull over. As I drove, the power to my vehicle had reduced significantly. During this time, the check engine light as well as the traction control light stayed on. After about 20 minutes or so, the lights went off and the car begin to operate without incident. After the day of the initial incident, I had the same problem occur 2 more times on 2 separate occasions. I have had my car since 2011 and I have had no accidents so I am not sure where or why this issue is happening but I am definitely not happy about it. I am also having issues with a knocking noise coming from my glovebox as well as the airbags light keeps coming on. Is there a recall that I am not aware of that affects these issues? If not, what can be done to rectify this problem. I am a proud chevy owner and would like to remain loyal to chevy however if I am not able to get some sort of resolution for these problems, I may have to look at going to a different manufacturer.
