had a near mishap with the MDX yesterday... it was my fault, but want to know if it is normal for the MDX to do this...

My wife and I were leaving to take our little dog to the vet yesterday when I realized that I left my wallet at home. We drove back home onto our inclined driveway. I got "distracted" when she handed me her keys to the house so I could keep the MDX running.

I was in the house and almost had the alarm disarmed when I heard a horn. I ran back outside and saw the MDX going backward down the driveway, crossing the street, and the back going up the neighbor's front lawn. I ran toward the car and opened the door to find the top half of my wife dived over onto the driver's side. She was using her hands to push on the brakes as she "greeted" me.

Luckily, she did this before the MDX reached the neighbor's trees or the front of the house. The front of the car was still on the street so I don't know if it would have stopped the MDX from climbing all the way onto the front lawn.

Apparently, I got distracted when she handed me her keys and did NOT put the car in park. Yes, my mistake. But I was surprised that the MDX would roll backward continuously while it was in drive. She said that she tried to put the car in park, but since it was moving, she couldn't get it in that gear. Since you had to pass "R" before going to Park, the car just accelerated backward while she tried.

I put the car back in our driveway, left the car on reverse and sure enough, it just rolled backward continuously. Is this normal? I haven't had a chance to try it on our Maxima yet. I thought that it could only move forward while it was in drive.

Luckily, the dog, wife and MDX are all ok, but it will be a while before she will forget this in our "conversations."

Rolling backwards

Most cars will do this now. It used to be that the torque converters and idle speed were matched so that unless you were on Pike's Peak you could let your foot off the brake and the vehicle would stay put.

As efficency has become more important, the manufacturers have lower the idle to just barely ticking and the transmissions are designed for similar "no load at idle" operations SO you really have to keep a foot on the brake -- another reason to appreciate a handbrake even in an automatic shifted car too!

Man, that reminds me....

My dad's 57 VW bug; steep street in Queens NYC; me 9 year, brother 7... playing rocketship in the car parked in front of the house- you know, space program, Gemini,- we'd sit with our backs on the seat and our legs up towards the roof.

My brother reachs over to the hand brake and yanks it...off we go, backwards, and up side down. him trying to steer based on a view of the sky.

I do the smart thing- emergency dismount out the passenger door. And go running to get mom.

He successfully pilots the craft past a phone pole, and between two parked cars onto the neighbor rhodedendron bushes. As I remember, he looked mighty proud exiting the capsule...

I do recall tearfully pleading for her not to kill him as she beat the crap out of his bottom. (Just a paddling as he ran upstairs, but from 9 year old eyes it was scary.)

I hadn't thought of that in 10 years....

But, incline driveway or not, I don't think you'd have been any better off :eek: if the 'X went forward into your house, either;) .

Man! this is wierd. I drove on the streets of San Francisco and I did not experience any of this. This is really wierd. Is this an MDX issue or just related a particular batch of MDXs?

This used to happen with my 86 Camry and my 93 Jeep Grand Cherokee. I'd roll back the inclining driveway when I turned off the car in Drive.

Mine does it.

Figure that if it didn't, someone'd be complaining that you need to stand on the brakes to keep t out of the car in front of you in traffic...

Never really noticed it come to think of it.
