Q: Jerking motions during turns and minor jerks or surges at highway speed

asked by on

All behaviors are on dry pavement. When going through a turn and beginning to accelerate out the car will occasionally jerk. It doesn't really feel like a shift and the jerk is very sudden. I've checked and changed the transmission fluid, cleaned the mass airflow sensor, and the throttle body. Also, when driving at highway speeds I feel a very slight hesitation. It occurs infrequently (every 1-3 mins). During both the these scenarios the air conditioning is running. There are currently no check engine lights.

My car has 68000 miles.
My car has an automatic transmission.

You should first make sure all 4 tires are of the same size and brand of tire with similar amount of wear. Tires that are different sizes or amount of wear will turn at a different rates and can cause the differential to jerk or hop in a turn.

If the tires are same measuring with the tape measure then you may have transaxle internal clutch binding issue. The slight hesitation you feel may be from normal A/C compressor cycling. If the A/C system is not as cold as it should be then you may get faster cycling. This may be normal.

If you’d like to have this looked at, consider YourMechanic, as a certified technician can diagnose the rough driving symptoms you’ve described and help make the necessary repairs.
