I have my hybrid into the dealer now for the same problem they stop-gapped 9 months ago by "burnishing" the tranny. I noticed the drive light flickering, esp. at high speeds and accelerations, but inconsistently. When I took the car to the dealer, they acknowledged a service bulletin, and demonstrated the shudder, or "judder," and burnished the tranny. The drive light continued to flicker intermittently since then,and now the car jerks horribly when driven at slight acceleration (just above idle, as in driving thru a parking lot). This jerking is also noticeable at slight accelerations driving thru town. This time they intend to replace the EGR valve, which I contend is another band-aid to put me off until my extended warranty expires in 4000 miles. Any suggestions?
