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 !!

When starting from a stop the car jerks as if the transmission is trying to catch up and it feels like you've been hit from behind. It's an on and off problem but it happens in the rain and is dangerous the dealer changed the trans oil and it still does it. Next the car goes into "reduced engine power" and "service stabilitrak" while driving and will not let me finish my highway drive safely, no one at the dealer can help with this except to say it will cast a lot of money to fix. Headlights constantly burn out and I bought expensive lights last time and one is already burnt out. I have only 1 payment left and the car is ready for the junkyard, you would think after $28000.00 it would last a little longer. What happened to gm??
