2009 Chevrolet Impala: engine knocking or ticking

Filed Dec 31, 2024 · Electrical · TX

I have a 2009 with 77000 miles 0n it I have fix the knocking noise under dash 3 times now it is a actuator there are 2 of them. I have also found by spraying Carburetor cleaner in the throttle body just remove the the big air hose and spray all around in side this stops the the speed reduction control lite from coming on saying you have no power. The problem I'm having now is while I'm driving the dash lights go out and radio light goes dim. after a while the lights come back on bright and working great they go on and off when they want to The lights showing me the mileage works great all the time its just the dash lights going on and off and my car just pass smog in California in June. I now live in Texas ,I have to have my car inspection here and it failed do to a EVAP and a 02 sensor not responding. They tell cause I replace the battery this cause the computer to reset and these 2 sensors have not reset yet and I have to drive the car 100 miles to make sure they reset to the computer So these are the problems I have been having with my car. You can find your car problem on you tube by putting in the year and make of your car saying what light came up and usually its a easy fix

Purchased vehicle and the following day the right front headlight went out and had to be taken in for electrical problem. Later about 4 months after purchase the air bag in the front passenger seat started to make a knocking sound and then stopped. Just recently it began making the knocking sound again when I open my car door, as well as close it. It lasts about 3 minutes and then stops.

I know this shouldnt be a safety issue but on most every impala the AC does a clicking noise and blows hot when the AC is on and blows cold when the heat is on ( which could be a safety issue because you cant get the windows to defrost) most people I know their impala does this. This should be a factory recall. When there are so many out there doing this same issue. The car will not even be running and the ticking noise will start if you shut a car door beside it.

2009 chevy impala lt malfunctions 'blend door actuator not turning causing the temperature control system to not work properly: *the heater blows cold air when in park *there is a loud knocking sound coming from the dashboard. When I start my car, unlock my car, open a car door (driver, passenger, front, back) and while my car is parked with the ignition off. 'the front driver side door lock mechanism not working: *I have to manually lock and unlockthe drivers side door with the key and sometimes my kids have to unlock door from inside the car. 'left passenger power window won't roll down. The last two items could result in a short in the circuit board. A short may cause the power door lock and power window switches to become inoperative. These could cause overheating, which could melt components of the door module, producing odor, smoke, or a fire increasing the risk of personal injury. Mechanic said that these malfunctions are a common problem in chevy impalas so it seems that these are obviously faulty parts. I am extremely aggravated that this is a known and consistent issue with this car yet have not been recalled. Not good! There are several actuators, they all need to be replaced. Gm should do a recall on this model to fix these items. Could be significant if there's an emergency and I can't unlock the door and can't roll left passenger window down. The last two conditions could increase the risk of injury during a crash.

My car occasionally makes a ticking noise from the dash. This comes and goes periodically. It starts when I open the door (any door) and continues for about a minute. In the period when this noise comes and goes the doors will automatically lock, I.e. If I step out of the car (running or not) and shut the door it will automatically lock even if I did not hit the lock button and even if I do hit the unlock button. Twice this has occurred when the car was running and my dog was in the vehicle (along with my purse and keys) causing me must distress. I believe this is something faulty in the make of the car. By the time I get to a dealership to have it checked out the clicking has stopped or it is not locking automatically. The dealer says it has to be happening while the noise is ongoing. There are no lights on the dash to indicate a problem. This first started about a year ago and the most recent incident was today (the date listed below). Thank you for your time.

I was driving on the freeway when the traction control light came on and message came across saying service traction control: then check engine light started flashing rapidly at the same time. Follow by a very loud knocking noise from the engine. Then speed would not accelerate. Turned on flashers and coasted to the shoulder. Vehicle had troubles restarting and would not move. Steering wheel was hard to turn. Tries to die while idling after you get it to start. This is not the first time this has happened - but never on the freeway which was very scary. I went to the dealership who was already aware of the problem and said without a warranty I could not be helped I could pay $700 to fix it though. They could have caused a death with knowledge of this problem and how quickly you lose power I was lucky this time, but this should be a recall situation, unbelievable.

Even when car is not running, loud clicking. Can be heard outside of car. People ask why is your car "ticking" when in parking lots. Tough to explain as of late with fears of isis terror threats. Reports say AC accuator, $400 to replace. Gm needs to correct this before impalas are mistakenly deemed threats when sitting in parking lots.

The first incident was in january. We had some bad weather and I thought it caused the problem. But recently, the car loss power again and would not accelerate. The losing power and the traction light came on.I mentioned this to the dealer when I went for the first recall for the ignition switch. The rep at chevyland in shreveport , la. Was disinterested. I also mentioned that there was a knocking noise in the dash. He advised all the impalas have that but it is not a safety issue. I now received the recall letter stating the very thing I advised the rep of. Now they are saying they may or may not cover it. This is a safety issue. If I am trying to accelerate and can not I could be hit by an 108-wheeler or anything could happen.

While driving onto a highway when I reach 56 miles per hour my vehicle lost power and slow down the brakes locked and the electrical system went haywire. The locks started locking and unlocking while the vehicle was in motion. The lights started flickering on and off and the car started shaking rapidly and the brakes locked up. Once I started the vehicle back up and the ignition switch seemed to be stuck and the air bag light displayed on the dashboard. When I turn off the vehicle and try to remove the key the key will not come out so I have to put it into neutral and back into park a few times before it will release the key. Since this has occurred I hear a knocking sound in my glove box when the door is open and closed and sometime hours after ill hear the noise and the electric will flicker.
