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.

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!!

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.

- service stabilitrak. A reduced power light usually indicates a fairly serious problem with the throttle system. When this light illuminates the vehicle will often go into a 'safe mode', which will severely limit the speed of the car and in some cases will render the vehicle un-drivable.

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.

I was driving on the highway and received the following message, service stabilitrak - reduced engine power. This has come up a few times. This time though while still driving my engine power was greatly reduced with the error, "starter disabled, service throttle". This LED to a drastic decrease in speed with zero control over throttle and moved to the shoulder and the car rolled to a halt.

On 1/29/16 my car died and towed to dealer where I was told I need a transmission. The car only had 69000 6months ago dash board lights lit traction control, reduced engine power service stabilitrack ABS.when I would step on the accelaretor pedal it would make a winding noise go to the floor and pop back up again. As I was driving down the highway all of a sudden I had no acceleration car had died. L pulled to the side of the road a few minutes later started up again this happened numerous times I told my son he couldn't drive the car because I felt it was unsafe. I called the gm they gave me a coupon to have the a diagnostic check on it. In sept I went to the dealer and he scanned my car for codes I was told I needed a right front hub part number 13582664, a right wheel speed sensor harness, 10340314, accelerator pedal, 84018392, and a vent valve 2085252. I can't believe a car dealers would let a person leave not informing the customer what a safety issue this is. I drove the car for a day because I couldn't afford to fix it and was trying to come up with the money again the car died on me as I went to accelerate now the car is sitting in my yard dead as a doornail. I called the dealer and explain the situation to the dealer at lannan chevrolet in woburn and I spoke with the owner and the only response I got was what do you want there's a hundred thousand miles on the car I have been doing lots of research on this particular vehicle and I'm appalled between a 2008 and a 2011 there has been hundreds of complaints about the same issue.these are safety issues where people can get killed. Out of all these safety issues there's not one investigation that has been opened in regards to the issues. The federal safety agency or gm needs to open an investigation immediately on these cars. There is a major safety issue and a recall is necessary.VIN number..(xxxxx) redacted to protect personally identifiable information pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

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

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
