I was at a stoplight, waiting to making a U-turn. The light turned green release the brake and went to hit the gas. The entire vehicle shut off. I lost all power and had to restart the vehicle in the middle of the intersection with vehicles behind me.

The thermostat failed causing the vehicle to go into a reduced power mode while climbing a hill with a trailer. The dealer has a technical service bulletin for this issue but the overheating can call engine damage or an accident when the vehicle has reduced power.
