Dt*: the contact stated in the early morning of 8/19/2006, police and witness reports suggested the vehicle veered off the right lane onto the breakdown lane, and then swerved across and off the left side of the road, flipped upside down, impacting a tree on the right side of the vehicle. The road was clear and dry. A witness stopped to render assistance, ran to the vehicle, viewed the situation and returned to another vehicle to call in the emergency.

August 2006 CrashFireDeath

In the 2nd year I owned my truck it noticed that when the outside temp got below 50 degrees f that my speedometer would stop working. When it warmed up 10-15 degrees it would start working again. After about a year of this it just became completely unreliable all the time regardless of temp. Now it just sits between 50-120 MPH whether you are moving are not moving. This last year the gas gauge also became completely unreliable.
