Pulled out into oncoming traffic and vehicle hesitated and would not accelerate. Dash lights came on and car stalled.

I called Toyota road side assistance number and 2. 5 later no one showed up. Called again and demanded a different tow company respond and 30 minutes later someone was at the scene.
