2010 Toyota Prius. 50,770 miles. When I made a sharp turn, all check engine and warning lights came on (no buzzers - just lights) and a screen display to 'Check Hybrid System'. The 'Check Maintenance Schedule' light warning has been showing the last 9 months... 2 different mechanics at Grease Monkey & Firestone Auto Ctrs said they tried many times, but could not get the 'Maintenance Schedule' display to trun off after oil changes...
Engine temp and Hybrid battery/system info is all normal. I hear a light 'revving' sound from the engine, and the acceleration is poor at best. Once I get to my speed, say, 45mph, the car does fine. But accelerating from a stop or up a steep hill is awful... It's as if my 4-cylinder had been cut to a 1. I had an Audi sedan 20 years ago and remember similar issues when its Oxygen sensor failed.
I will take the Prius to the dealer for diagnostics. Ideas?? Could you give me a ballpark on how much the dealer or other would charge for the sensor?
My car has 50750 miles.
My car has an automatic transmission.
