Jerelee Bassis (Montgomery, Maryland) - 2006 Toyota Matrix
A sensors question. The car is perfect, except when she parks in front of the house, it sounds like it's settling like an old woman. The car heaves, groans and even shudders. It only does this when she parks in front of her house, which is on a slight decline. Problem is parking brake not fully engaging, so car is trying to move. She experiments on air putting it in park first, so the parking pawl engages, and then putting on the parking brake, and noise goes away.
