Said It Here

Why does my car jerk and whine when accelerating around a turn?

Car jerking and whining exclusively during turns while pressing the gas pedal usually points to a drivetrain or differential issue, since the problem disappears when driving in a straight line. This sudden kicking sensation makes driving unpredictable and prevents normal, smooth acceleration from a stop or around corners.

    suspecting motor or transmission mounts

In their words

Today I experienced a strange jerking (kicking) sensation when accelerating from a stop while turning a corner. The car feels almost like it wants to "jump" violently, accompanied by a whining noise.source ↗

Now, it happens every time I turn while pressing the gas pedal. This does not happen when driving in a straight line—the car accelerates properly with no RPM fluctuations or unusual noises.source ↗

Lexus didn't figure anything out and I need some help (I suspect they only drove it and checked for codes).source ↗

When it's parked and idling back and forth awhile between ICE and EV, it jumps pretty violently when the ICE starts back up.source ↗

Also, you know how it appears to shift up and down on the highway, it jerks/jumps/hammers when you completely let off the gas at highway speeds and it shifts, or when you give it a bit more gas and it downshifts.source ↗

To me it seems like motor mounts or trans mounts but I haven't been able to look, no car work at my apartments.source ↗
