 The truck rolls back when stopped on an incline (ie red light, stop sign) on dry roads & the SPS kicks in. The truck then doesn't allow the operator to move forward, it just keeps on rolling back and clicks. I almost had a couple of accidents because of this. I brought the truck to the dealer & recreated the problem with a technician in the vehicle. He said that he's never seen anything like that. I left the truck to get fixed. Later that day the dealer called me back and said "they have recreated the issue with other new vehicles and also contacted the Toyota engineers. The engineers advised that it was designed like that and I would need to live with it."...What??? I need to live with this?  This is totally UNACCEPTABLE.  This is a MAJOR SAFETY ISSUE!!! The dealer also said they can't do anything about the issue and referred me back to Toyota. I have made repeated calls to Toyota to get nowhere. They say the truck was designed that way and has no manufacturing defects. I tried to tell them this is a major design flaw but they are brushing me off. I asked them "Are they waiting for someone to get killed" ?They didn't respond. For a automaker to know they have a major safety issue in their product and do nothing about it is very concerning.  Just like the airbags...they're waiting for people to die before they do anything!!!!!
