CAUTION! must use the parking brake on incline

Idle neural is a bit more common nowadays with manufacturers trying to make fuel efficient cars. Either the CLA is equipped with this feature or the torque in the small engine isn't enough to hold the car. Either way you should never rely on the transmission alone to hold a car on an incline.

Tony, with your comment on it rolling back then stopping makes me wonder if it is also equipped with anti rollback. Was it decent size incline and can you feel the brake disengage when pressing the accelerator?

Unfortunately, all articles are still focused on reviewing the car instead of the technical details to find out.

The incline is very slight but enough to make the car move but only a little bit. The car does have anti-roll back feature.

Thanks for clarifying.

That it's the easy way out but I would rather have it fixed if it's an issue. If you're able to duplicate, pick up a service manager and take him to your house or where you're able to duplicate.
I've taken a manager on a ride along when his techs couldn't hear a noise I heard on the same turn I took every day to work. Came back from the drive and they installed new shocks.

You can always try a different dealer as well. But don't put a bandaid on it if it's an issue. You may someday forget to engage the p brake and could hurt someone.
