Cruise Control problems of the 2006 Honda Civic Hybrid

When going up a hill with the cruise control set, the rpms will increase in order to climb the hill whilst maintaining the same speed. Once the peak of the hill is reached, though, the rpms will not return to the normal range (between 2000 and 3000). This will continue indefinitely unless I slow down below 40 mph, or shift from d to s and then back to d. While I have included oct 5th, 2007 as the incident date, that is approximately when I first noticed the issue. No doubt it has been occurring throughout the lifetime of the car, but this is when I first became aware of the problem on a long road trip. The problem persists. This is wasting a considerable amount of gas, as well as putting unneeded wear and tear on the engine and drivetrain. Honda maintains that this is not triggering any error codes with the system management in the car. However, this behavior is surely not intended, and others have reported the same behavior on online message boards.

Unintended acceleration. 10 miles after a cold start-up, the car went to full throttle. I was able to hold it in place with the brakes. I turned the ignition off momentarily, but the car went back to full throttle. I then turned it off for about 15 seconds, and the car reverted to normal operation. The cruise control was "on", but not engaged. No speed had been set after the initial startup. This is a hybrid with full throttle by wire. I took the car to the selling dealer, who had no service bulletin on this fault. He said I would have to leave it until they could replicate the fault. Knowing the futility of this, I declined to leave the car. The fault has not reappeared.

I have a 2006 Honda Civic Hybrid that numerous times now (virtually all the time), the cruise control will not slow down when instructed to slow down by pressing the decrease speed button one press at a time. Usually I will have to hold it down for several seconds for it to respond. The vehicle was taken to the dealer they stated there is not failure and now the warranty has expired. The manufacture also was call and they stated there is nothing they can do. The failure mileage was 19,000. The contact requested that the complaint be written verbatim with no revisions.
