2011 Chevrolet Impala: check engine light

Filed Dec 25, 2023 · Electrical, Engine · MI

i own a 2011 chevy impala 4 door that has a very serious engine issue. I was on my way home and suddenly the service stability trac, and check engine light came on, then the message center displayed reduced engine power and low oil pressure then the engine shut off. I tried to restart the vehicle and it would not restart. I got it towed to a parking lot where it sat over night then it would restart but only for a few minutes. Once I got a scanner hooked up it had a p0642 code lost 5 volt reference circuit 1 and a cam sensor code I worked on this vehicle for two days and still have not found the issue. this vehicle needs a recall since this is a recurring issue with a few different model years of this vehicle and its always the same issue word for word, check engine light comes on, service stability trac, reduced engine power and low oil pressure lights come on the same p0642 lost 5 volt reference circuit 1. This is a very dangerous situation when going down the road and you lose engine power, steering and braking power. GM needs to correct this issue too many people have had this same issue.

This problem has happened for many many years. Made appointments @ Fuccillo Chevy dealer, by then it’s gone off & they don’t know! Well, just occurred again when getting new tires @Dunn pulling in. 2011 impala Stabilitrak, engine power loss, then check engine light! Thank goodness the mechanic printed me the codes & what they mean!! SO- P2138 Throttle/pedal pod sensor voltage correlation DTC P0523 Engine oil pressure sensor/switch high input Same complaint of loss of power as I’ve now seen others write about!! Voltage referring to throttle ‘s ability to open/close properly. An electrical malfunction in manufacturing! RECALL!!! Obviously I actually have another impala- 2007 that the rear defrost wire’s actually burnt @ control junction, been replaced now. Could’ve caused a fire !! High beam lights come on intermittently when using the turn signals!! Stand by your product !!!! I have 2 Impala’s, 2007, 2011. My mother has Impala, 2015. My sister has an Impala, 2017. Impala family I guess- kinda funny, all are black Impalas!!! I’ve seen numerous complaints of this same issue! Defect! R u waiting 4 an accident or a death? GO !!!! Has happened numerous times b4 This report, Chevy dealer has previously stated can’t anything because the code disappears on its own. What’s with that? Resets itself?? It does!! Sure have had it happen, 20 x’s?? I make an appointment & by that time- gone! Seriously!!! Finally caught it 2 code it !!

Today, 6-12-2022, driving on US Highway 80 at 65 mph headed toward Phenix City, AL from Columbus, GA, the the engine shuddered, then the "Stabilitrack Service Light" came on, along with the check engine light, and a message for "reduced engine power." Then, the engine suddenly cut out as I was going uphill between the Riverchase Exit and the Summerville Exit. Luckily, I was driving and not my wife. I was able to glide the car back to the right shoulder of the road under ZERO power, and shut the ignition down. Cars were passing me at 65-75 mph, and I was very fortunate not to have caused an accident. After sitting there for about 5 minutes in 96 degree heat and my wife freaking out in the passenger seat, I restarted the car and eased it to the Summerville Exit, and slowly drove home, about another 6 miles. We were damn lucky not to have been hit by another car, as this happened on a what is essentially a freeway. After researching this , it seems this is a common problem being reported on this Model, the Chevy Impala. I'm sure Chevrolet knows about this...the company should be forced to recall this car model and fix it before folks start getting killed due to total engine failure...especially at a high speed like I was driving.

Vehicle randomly gives check engine light and reduced engine power, service stabilitrack. At this point engine power reduced to point that is very dangerous. While passing (safely) it came on and I was stuck in oncoming lane because I didn?t have the power to complete pass. Happens every week several times. This occurs while driving and sitting. Even in park it will occur. Completely random whether driving, sitting, or in park running.

Check engine light came on. Message came across saying reducing engine power. Then said to service stabilizer. It then turned off traction control. We were driving home from vacation when this happened. After a bit driving the whole car shift off while driving 60mph on a busy highway. The message on dash said it disabled our starter. We almost did not get off the road safely we were in the left lane and could not get to the shoulder. My husband had to make the decision to pass across into oncoming because thankfully there was no one coming.

January 2019 was driving on a very congested interstate 95 at the posted speed limit of 65. A warning popped up on my dash board.service stabil trak engine in reduced power. It was like I longer controlled my car. The speed suddenly dropped. I went from 65mph to maybe 30mph. It felt like my brakes were being applied . I became scared and almost started to panic. But because I was in the far right lane I was able to pull off the interstate. I sat there on the side of the interstate with my heart racing and my hands locked on the steering wheel so hard they cramped up. I turned off my car and removed the keys from the ignition. I thanked god I was alone in that car. I thanked god the car behind me was not tailgating me. I waited for about 5 minutes and then put the key back in the ignition and started the car up. The warning was gone but the service engine light remained on. I was scared to death to merge back onto the interstate so I put on my flashers and drove on the shoulder at 20-30mph until I got to the first exit. I made it home. I called a car repair company. They told me the sensor more than likely need to be reset. They suggested I take it to a chevy dealership service center. The next day I started my car up and all warning were gone so I did not take it to the service center. The car ran fine until today 52/20/2019. I just filled my tank up with gas. Turned it on put it in gear and drove 20feet when the same error came on . I had looked up this error on the internet. Seems lots of americans have almost been killed because a car maker has a mechanism built in to it vehicle that takes control of the speed to which the vehicle is traveling. People are spending a lot money to fix an issue that seems to not have a fix. Chevrolet is putting the lives and the lives of others on the roads in jeopardy with their stabil trak computer sensors.your failing americans

Driving at about 70mph my check engine light came with with the reading service stability track, engine reduced power an disabled started, service throttle instantly I loss all rmps an my steering wheel almost fully locked while the car was still on motion. Luckily I was able to jus barley veer off the road into safety. Why would a car company have something like this in thier vehicles. That would lock the steering wheel while going at accelerated speeds

When driving the stabilitrak light reduced engine power light comes on along with the check engine light. My car slows down and sometimes it would stall when stepping on the gas and the gas pedal would sometimes shake. After shutting the car off for about an hour or so the stabilitrak light would go off and after a day the engine light would go off as well. Whenever I take it to the mechanic to have it diagnosed and fixed they are not able to find anything wrong with it. This happens without warning often even when driving on the highway and frightens me with hopes that it does not cause an accident that could seriously injure myself or others, or cause a fatal accident.
