general problems of the 1996 Chevrolet P30

Auto park system on my 1996 rexhall motorhome has applied itself when the system is hot after a number of hours of driving. It has happened to me when backing, but I have read and heard of numerous occasions when it has happened to motorhomes when moving forward at highway speed.

I put my 1996 class a motor home in auto-park at a dump site. I got out of the seat to dump my tanks and my wife warned me we were rolling. I was able to stop the vehicle before it hit any thing. The auto park light was on and when I put the vehicle in gear I could hear the auto park disengaging, but it was never on. Vehicle rolls away when it should be in park and the dash states it is in park. I have to have my wife keep her foot on the brake while I put blocks in front and behind the wheels to keep the vehicle from rolling away.

P 30 chassis auto park brakes locks when shifting from drive to reverse, this happen after driving for some distance and unit being up to normal temperature. First time ths happen 300 plus miles from home and five days in the shop and with a charge of $880. 08 and then left the shop with the same problem I had when going there ,had to leave for home cutting our trip short because no one seem to know what to do to correct our problem. I contacted g. M. Customer service several times without any support or concern what so ever. After return home I went to several g. M. Truck service centers and only one would attempt to guess the cause and stated they would have to start by replacing parts which amounts to 13 , after the $1880. 08 already spents and problem not fixed I was not eager to let them start replacing parts again and having a unknown cost without assurance of correcting problem. This is the 2th time within 34,000 with auto park brakes problems. ( 1st time to be filed on another complaint form ) I know of a number of other p 30 owners who has experience auto park brakes problems and are very unhappy with general motors because they don"t seem to care about our safety or cost. Hope you will review all complaints and consider our request. Thank you.

The automatic park brakeon my 1996 chevy P30 chassie motorhome locked up on me when I was driving. Luckly I was only going slow in reverse. I was in the middle of a road way when it happened. I could not get the motorhome to move in reverse. Everytime I put it in reverse after the intially lock up it would engage the auto park and would not move. It was extremlly nerve racking and unsafe. I have not had it happen yet when I was going forward but I see an unsafe situation. , I contacted chevy and they had no information for me. Please help .

Automatic park brake came on by itself four time, while driving, twice at 10mph, once at 20mph, once at 45mph.
