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 !!

Service stabilitrak warning light goes off and on intermittently when this happens the traction control light comes on when hooked up it shows no codes everything I’ve read on line is that it’s a electrical issue to replace wheel bearings or gas pedal or other list of sensors shouldn’t this be something that you should investigate to let owners know what to fix it seems to be a issue on several different models of Chevy autos if forums are correct next step is it will go into limp mode or shut off completely that one would think would be a serious safety issue as you loose power steering as you have to fight to get to shoulder of the highway

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.

The car was purchased 06/23/2021. Approx 2 weeks or less later the car had to be taken to the shop where it was purchased at due to the engine going in the car. There have been 3 loaner cars given while car is being fixed however after now 4 months the car is still just sitting at the shop where it was purchased at without the engine being replaced or repaired. There is a loan on this vehicle and it is very unfair that the loan has to continue to be paid for when the car is not in possession of the owner. I do not want the car back at this point because it is now out of warranty and has been sitting for a long time without being fixed. I have called many times and have been getting the run around. Now the owner of the shop or workers will not answer my phone calls. My name is [XXX] my contact information is [XXX]. I am helping my son out because he is and have been getting the runaround since he purchased this vehicle from Ecars.

- 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.

I was driving and a part in my A/C began clicking loudly, then the air shut off completely and started smoking. A loud noise came from where the A/C blower motor is and within moments the entire car was engulfed in flames.
