Hey all,
Recently my 2014 Forte5 SX started turning off when coming to a stop or even leaving it in park for a length of time. After it turns off, restarting it takes a few tries and when it starts, the tachometer stays at 0 and the traction control light goes on but I can drive it although throttle response and shifts are weird.
Eventually it generated a P0335 error (Crankshaft Position Sensor A Circuit). Originally replaced it with a wrong sensor (Amazon said it was compatible with my car but it thought my car was a 2.0L). Even with that sensor it stopped turning off but wasn't shifting properly. Sourced the proper sensor (3x more expensive!) and had the dealer install it and the turning off never came back but it still doesn't drive quite right. Mostly doesn't downshift aggressively enough and seems to let the RPMs get lower than it used to. Almost like it's stuck in ECO mode
Dealer finds nothing wrong and thinks it shifts and drives just fine.
Anyone encountered issues with this? I'm tempted to buy an ECU Reflash since the dealer won't do it just to see if that resolves it.
Can anyone recommend an ECU tune? I figure an OBD Plug (performance chip tuning) that fools the ECU probably won't work to resolve this issue for me
