The automatic transmission (CVT) can have a "shudder" due to a worn start clutch. Replacing the start clutch should correct this type of shudder condition.

My Insight has had the shudder since new and was told by dealer it is normal. Had a frightening experience when leaving a strip mall going up the exit ramp, It was a slight incline. The ramp led to a busy street. The vehicle in front of us had stopped waiting for a break in traffic. With my foot on the brake, the car started to roll backward. When I pressed (slightly) on the accelerator the car surged forward. I could barely stop my car's forward motion and when I did, it again rolled backward. The car in front turned right onto the highway. I again pressed (slightly) on the accelerator but my car immediately surged forward onto the highway although I was only trying to go as far as the curb. I was almost standing on the brake, but it still kept going into the oncoming flow of cross traffic. The dealer when I brought the car in to find out why this had happened the service person acknowledged this will happen since all Hondas lack something he called a holding gizmo that most makes have to prevent the rolling backward. He had no explanation for the rapid surge. I left the car for the factory rep to examine this week. It was a frightening experience, not just for my sake, but I had my 68 year old sister and 91 rear old cousin sitting in the back seat. They both felt the surge and my sister actually gasped and asked what happened. I have read about this kind of problem with Toyotas, but not with Hondas
