If you own a car with an automatic transmission, then you may have experienced a hill start assist problem. This is when the car doesn't seem to want to move forward when you're trying to start it on a hill. The reason this happens is because the transmission is in neutral and the engine is not running. When this happens, the car will usually roll back a bit before it finally starts moving forward.
There are several ways to fix this problem. One way is to shift into first gear before starting the car. This will help to engage the engine and get the car moving forward. Another way is to use the handbrake. Pulling up on the handbrake will help to keep the car from rolling backwards as you start it on a hill.
If you're still having trouble getting your car started on a hill, then you may need to have your transmission checked by a mechanic. There could be something wrong with the way it's shifting gears that's causing the problem. Whatever the case may be, don't hesitate to take your car in for service if you think there's an issue with the way it's performing.
