Check Engine Light On problems of the 2014 Chevrolet Impala

Took my vehicle in for its regular oil change. A few days later, the car started driving funny. I notice that when I went to accelerate that the vehicle started shaking. After it happened a few more times within that same week, my check engine light came on. I decided to take it back to the chevy dealership where I had the oil change, not before calling the service dept. Several time in the week to voice my concerns. I was told to bring the vehicle in and have them check my oil level to make sure all was well. I told them what I was experiencing and that the check engine light was on and asked could they re-check my oil level. The service advisor checked and said that the oil was fine. She then suggested that I pay $112. 48 dollars for a diagnostic test, because that would be the only way to determine why the check engine light was on. I did! only for them to tell me that it was p2645 intake rocker arm control circuit solenoid. Then she game me a quote of $407. 35 to fix the problem. I was then informed that I had to pay for the part upfront before anything could be done and on top of that, this part was on back-order and that it would take weeks to fill the order. I need to use my vehicle to get around and this was not safe to drive! this was over 2 months ago. I then turned to the internet to do my research only to find out that is a faulty part from the gm manufacture. And gm was not willing to replace the part even after they place this part in my vehicle knowingly that this was a defected part and that down the road it would be faulty, not only in my 2014 but the 2015 chevy Impala's and the chevy malibu. This is not right and gm need to correct the problem. I am paying for a car for the last 2 months that I cant even drive! shameful gm!.

My 2014 chevy Impala misfires while driving and loses and regains power while driving. I took it to a mechanic and it is the rocker arm control valve solenoids. I did some research it this is a known issue for 2014/2015 Impalas and malibu's. This is very unsafe and can cause accidents. Also, this part has been on backorder for several months so owners are having to drive with check engine light on. This should be a recall.

I recently purchased this car used at a dealership. Before taking possession of the vehicle, the dealership tried to fix all problems associated with the check engine light being on. I was informed the vehicle will not pass inspection and the check engine light was still on due to a rocker arm oil control valve needing to be replaced. The car is still at the dealership waiting for a part that's on backorder and the part needed is gm #12633613 rocker arm oil control valve. After doing some research myself, I discovered this part fails commonly on my vehicle make, model, and year as well as 2014-2015 chevy malibus produced with the same engine. Gm nor any aftermarket companies have this part in stock. I've contacted gm and was only told they don't know when they will have this part available. However, a few others with the same issue have been told by gm that this part is discontinued. There are people waiting months for this to be fixed and gm seems not to wanting to provide a solution. I would get another vehicle but then I would have to spend hundreds of dollars for the loaner car I'm currently driving from the dealership. This is gm's problem and they should be held responsible.

I was driving my car and it loss power. The check engine light came on. I took it to nelson hall Chevrolet in meridian, ms. They told me that I needed an exhaust solenoid part number 12633613. It was sitting there at the chevy dealer for a month and a half. They told me to come get it because they didn't have the part to fix it and they didn't know when the part was going to be available. I have been in contact with GMC since December of 2019. GMC doesn't know when the part will be available. I can't drive my car!! when I spoke with GMC last, they told me they would be giving me a call back in 24-48 hours. It has been 3 months and GMC will not return my calls. My car is still broken as of today March 18, 2020. This is unacceptable!.

2014 chevy Impala needs a rocker arm oil control valve part# 12633613. Gm says there is no eta on the part but dealer says part is not being produced. Check engine light stays on, the car stutters during motion also will shake suddenly. Also, has a lack of acceleration.

The check engine light in the vehicle came on and the vehicle began to lose power and then regain power while accelerating and also while still in motion even while not currently accelerating. The problem was diagnosed by the chevy dealership and it was determined that a rocker arm needed to be replaced. The part (#12633613) is not available and there is no estimated time per gm when it will be available again. My vehicle has not been safe to drive and sitting at the dealership since October 15th 2019, it is currently January 8th 2020. This part is an issue for all 2014 and 2015 Impala and malibu vehicles with the engine type in the 2014 Impala LS. The dealership has referred to the gm part as being defective yet gm has not issued a recall. Gm refuses to provide any information regarding the part and will not even confirm if it will ever be produced again. This issue is effecting thousands of vehicles and gm's failure to address this issue is leaving the owners of the affected vehicles driving unsafe vehicles. Gm needs to issue a recall or manufacture more of the part if it is simply a production issue (which they will not confirm or deny).

While driving on the interstate the car has shut off and the lights pop up saying rear stability, abs anti theft detection, and the check engine light. The car has done this three times so far with my child in the car.

4/27 approx 5:20pm @ 70mph, "loss of engine power" and some stabilty warning came on. Check engine light and traction light lit, was in center lane, thankfully got to the left berm. Car would not accelerate. Turned off, touched brake a couple times, sat a few mins, restarted, ck engine light still on, but engine power warning not on, was able to get into moving traffic and took to dealier 4/27 apprx 7pm, with gm rental given to me. As of 1:12pm, no call yet, not sure what the issue is, but could have been fatal!!!! bad, bad bad!!! took a pic, blurry though, frightening! told dealer of sudden surges, but intake rep said it would all be related and didnt write it down.

Tl-the contact owns a 2014 Chevrolet Impala. The contact stated after getting the vehicle diagnosed several times the vehicle check engine light still illuminates on the panel. The vehicle was taken to the dealership four times where it was diagnosed with no defect. The contact feels unsafe driving the vehicle. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 50,000. Ng.
