Kevin Dillon’s Tesla suddenly stopped washing the middle of the car, followed by the rear.

The accident happened last Monday at a car wash in the Los Angeles area… where cars are typically left in neutral while they pass through the wash. But, in Kevin’s case, we’re told he accidentally got out of his seat, triggering the brakes… bringing his car to an unexpected stop.

Our sources say the accident resulted in a minor collision between three cars behind him. Fortunately, we are told, the damage was minor.

However, we were told that at least one person complained of discomfort, so law enforcement was called to record an incident report.

We’re told the deputy concluded that the “Entourage” star caused the accident, not the car wash equipment.

Our sources say there is a warning sign at the car wash warning Tesla owners that any sudden seat movements could automatically put their car into park mode, potentially causing injury or damage to their car or others.
