Weird Jolt in Cruise Control
2013 IS350 -- Anybody else experience a jolt when cruise control is set @ 75 mph? I drive the rolling hills between Tallahassee and Thomasville, GA, and after I crest a hill and the engine decelerates, sometimes there's a sudden jolt from the transmission -- feels like a hard shift, but the gear doesn't change. But after the jolt, the tach will float up a couple hundred RPMs, then float back down, like it's missing.
Also, even when not in cruise control, in 5th and 6th gear (auto shift), the tach floats up and back down just after shifting into 5 and 6.
