Hello everyone,

I have a service appointment with my dealer tomorrow.

This past winter my car started doing the following:

If parked overnight on a very, very, very slight incline (my home’s driveway), upon startup and shifting into reverse, the car jumps and jerks backwards (while my foot is of course still on the brake). Furthermore, I do allow the car to warm up for a minute.

I know that this happens to all vehicles when parked on a steep incline, but I’ve had the car since new, it’s never done this before, and it also only happens when cold out and upon cold start up; not again later in the day.

Then, in addition to the above, once the vehicle is out of the driveway, I shift into drive to make a left turn, and as I let off the brake the car moves / coasts a small amount and then jumps or lurches forward (while turning) and subsequently smooths out, with no further issue. This jump or lurch is shocking and violent.

Anything come to mind that I can relay to the service advisor / shop foreman?

Awful how I feel the need to consult this [most knowledgeable] forum on matters first before visiting the dealer; you’d think that a clear description of same would be sufficient to get down to the bottom of things with them; but no, not with our vehicles.

Thank you very much.

Is the front or the back of your car higher on the incline? The transmission oil pickup is in the front of the transmission. If the back is higher and it is better in that position, this points to the fluid is too low.

Yes, you are correct, back is lower.

Any idea why this may be weather dependent; usually only see this happening in cold weather.

I will definitely have the dealer check the transmission fluid though.

Many thanks!

The fluid expands with heat. So with cold weather, the fluid level will be lower.
