No engine lights on but it does this small jerk between 30 to 40 mph just jerks one time but after I speed up it doesn't do it and it does it every once in a while not every time I drive it.
My car has 67000 miles.
My car has an automatic transmission.
The jerking could be due to the turbocharger (if equipped) or it could be a transmission shift issue. If turbocharger related, it is probably "normal". If transmission related, some tests would have to be performed to determine the cause and the possibility of ECU/TCM software updates should be considered. To distinguish between the two broad possibilities (engine, if turbocharger equipped, versus transmission) requires that a mechanic drive the vehicle. If you desire a diagnostic, please schedule via YourMechanic’s automatic transmission shift diagnostic service request page.
