Here is the reason I am asking this question. After replacing my front wheel bearings in September, when driving in Automatic mode, the car shifts from 4th gear to 5th, and then downshifts back in to 4th and then back up to 5th and so on. It seems it has some kind of drag that makes the car thing it is climbing a hill. I have been driving with the paddles since September, but whenever I try automatic it continues the downshifting again. I know that the new bearings were tighter than the old ones that were replaced, but I figured that by now (about 1200 miles later) that they would have loosened up.
I was just looking for answers and was wondering if there was any way the "hill start assist" function were somehow not releasing the brakes completely. I know that if I take the front wheel off, I can't spin the front hub at all unless I unbolt and swing the caliper away from the disk. Then the hub will spin a turn before stopping. The nearest Smart Car dealer is in St. Louis around 180 miles north of me and they have been very little help. Their only advice is to bring it to St. Louis so they can check it out.
Is there any way that the "hill start assist" function is causing the brakes to not release completely? If so is there any adjustment that can be made. Any help would be greatly appreciated.
