Loss acceleration entering highway ..stalled out at 40 mph..next day driving back to normal. This has happened 3 or 4 times.

Kingston Hyundai replaced valve body-$1103.57(warranty) Control-arm-(warranty)

Stalling is really bad during cold weather;(-5 degrees celcius Once it warmed up it was better but still isn't right.

On at least three occasions, my car has near stalled on pulling out into traffic. The last time, if I had not pulled to the shoulder, I'm certain that we would have been hit. The truck barely missed us, but I had ZERO get up and go, just slowly sputtered. I now wait until I have at least no visible traffic coming, I just don't trust it!

Hyundai called out their 'engineer' to evaluate the problem and they are 'unable to reproduce' the issue, thus commenting that all must be normal. The acceleration problem has happened several times and yet they refuse to accept that there is a problem. I also filed a complaint at NHTSA.

This is a problem that Hyundai will not even acknowledge and this seems to be a common complaint with the hybrid drivers.
