2012 Chevrolet Impala: check engine light

Filed May 10, 2024 · Engine, Fuel system · IL

I have trouble codes that occasionally come up even after vehicle has been serviced. The vehicle used to drive fine. Now it started miss firing. I was told the problem was coming from the engine compartment/sensors. An OBDII diagnosis detects a problem with B Camshaft Position Timing Over Advanced or System Performance Bank 2 (p0024). I fear that without the fix, the miss firing can cause an accident. The engine light is illuminated when this happens.

I have a 2012 impala that I have had since 2015 and a little while after I got it the engine light came on and it said it was the fuel pump control module requested Mil illumination and evaporated emissions systems leak detected (large leak) and at times the gas tank sparys back at up if you don't let it sit open for a little bit. I have had these issues fixed multiple times and by multiple mechanics who still can't figure out what's going on.

1st - 8/11/2018 - 79,653 miles - check engine light came on, code p0411 secondary air injection system incorrect flow detected. Dealership stated the solenoid malfunction check engine came back on, code p0411, chevrolet stated the secondary air injection system is functioning as designed and reset the code. Chevy's stated the faulty sir injection solenoids bank 1 and 2 was the cause of the check engine light code p0411. Advised me that the battery terminal may be the issue and recommended changing it. Recommend a new alternator. Chevy was unable to verify the code p0411 but made a recommendation for the issue. Check engine light came back on again, no other issues with the vehicle at that time. Gm opened a tac case. Advised by tac that carbon buildup in the cylinder valves from the cylinder heads was the cause. Told to drive vehicle for a few days. Within 3 days check engine light came back on. Chevy installed a vehicle data recorder per the gm field service engineer. Test results showed both air injection cut of valves needed to be replaced. Future also updated ECM calibration and programmed it - covered under warranty. 6th visit on 9/3/2019 at 85970 miles chevrolet advised the cause is due to the left temperature control and air inlet actuators. 7th - 9th time, advised by independent auto repair shop, that everything was working as normal. Check engine light code was reset. Advised car needs to be calibrated at gm-approved dealership. As of today, the check engine light remains on. The final shop advised the issue may be that the system was not calibrated or just needed to be calibrated every time the check engine light came on. I believe that thousands of gm customers are paying out of pocket for unnecessary p0411 repair work.*dt

When accelerating forward from a complete stop the traction control comes on by itself causing the wheels to lock up & causes hesitation. The ground is not wet at all especially when turning the traction control kicks on causing the same reaction on dry pavement. When accelerating the car hesitates & jerks/jolts then the traction light kicks on. There are no codes on the dashboard & no check engine light.

While driving 30 MPH on city streets going straight with a slight incline the A/C and radio powered on and off several times. When stopped at a stop light the doors unlocked and "service stabilitrak" flashed on and off the dash, the radio powered down, and the A/C turned off. After a few second everything went back to normal. No check engine lights came on at all. This is not the first time this has happened.

I was driving on a residential road and I took a turn onto a different residential road and right after I started to accelerate the check engine light came on. Right after, the service stabilitrak and service traction control light came on. The car started sputtering and when I started to stop the brakes locked on and off as I came to a stop. It continued to sputter every time I accelerated and the brakes continued to lock every time I had to engage them. I could barely get the car to drive faster than 25 MPH. Once I got home I popped the hood and the engine seemed to be shaking.

While driving on the highway the check engine light & traction light came on at the same time as these 3 messages, engine may loose power, severice traction control, stabilitrack. The engine started slowing down & had a high pitched whinny noise. After about 10 miles the message changed to engine iis loosing power, wouldn't go over 35 MPH and the whinning became louder and faster. I had to have it towed to a gm dealership, where they diagnosed it as the high pressure fuel pump. I was told the parts are on back order until may 15, 2018.

Takata recall when accelerating forward from a complete stop the traction control comes on by itself causing the wheels to lock up & causes hesitation. The ground is not wet at all when this happens & has almost caused me to get rear ended. Even when turning the traction control kicks on causing the same reaction on dry pavement. When accelerating the car hesitates & jerks/jolts then the traction light kicks on. There are no codes on the dashboard & no check engine light. Taken it to the dealership and they aren't able to figure out the issue. This is very unsafe especially driving on the highway and driving with children in the car. It risking my life, my children's lives & the lifes of others.and have spent a lot of money having the vehicle checked out with no solutions. This is very dangerous.
