In my quest for all the information I can get, I recently read several discusions (on another website) on a problem with the HCH bucking badly. Seems most of the folks reporting this problem had '03 and '04 model year cars. Anyone seeing this issue on the '05 HCH ? Just wondering if they finally found the problem and cleared it. Seems the fix for the '03 and '04 was transmission service, which did not always help.

As always... Thanks

No chance of human error?

I've had my '05 HCH for 6 months. No transmission problems whatever.

i have an 04 hch with almost 16,000 miles/16 months, no transmission problems, cvt runs as smooth as it did on the first day.

bucking issue? Please be more clear about when it happens and how severe it is. Does the car suddenly lurch during initial acceleration, coasting, or braking? Could you link us to some of those forums on the other site?

For me, when I have just started my car and it is cold outside, when I first depress the brake pedal, regenerative braking doesn't kick in until a second or two after I brake, and the car can "jerk" a little bit when it finally does kick in. This doesn't happen much though, and when the car's warmed up it never happens to me at all. I don't know if this is what you are referring to.

I wasn't aware of any CVT recalls/fixes for the 03/04 hch. There is another thread here that talks about government fleet hch transmissions and catalytic converters dying around 90,000 or 100,000 miles, but you know how badly they drive those cars.

i have an '05 and haven't noticed any problems. the only lurching i've ever seen was when cruising with FAS and then starting in neutral, but this only happened once and every other time has been smooth.

I will take a stab at this. My 05 HCH does exhibit a symptom that might be called "bucking". It is when I am coasting with cruise control. If the car slows down to the point where re-gen kicks in, the cruise control thinks it needs more gas. So now the car accelerates, re-gen goes off, car speeds up, re-gen kicks in again. Then the cycle continues.


Am I close?

My 03 bucks, but it's due to the regenerative braking not the transmission. It always happens when I'm coasting just after applying the brake, then letting it off. For example, I'm slowing at a light and apply the brake, but realize I can coast a while and release the brake. For some reason, the regen braking pulses for a time then fades. Also happens in reverse as I back out of the driveway. I asked the dealership once when the car was new - they said that was normal. However, I don't think they really had any idea what I was talking about. Back in 03 I new more about my car then the dealership. Anyway, I just live with it. Does not seem to be a big deal, just an anoyance. Car is at 45K with no problems.

I have an '04 HCH MT and have not had anything resembling this problem.

The closest thing I can call bucking is sometimes when you stop quickly and the regen braking is occuring, the car will "buck" while kicking out the regen braking because the car is going too slow at a higher gear (like if I'm in 4th gear and I'm going to zero miles per hour, at about 10-20, the car will turn off the regen and I'll pull out of gear and into auto stop)

can you explain in more detail how you get this to happen? when you say "coasting in cruise control" do you mean hitting the 'decel' button?
