I have been reading articles everywhere about numerous Toyota vehicles that are older than 2007 having issues with sudden acceleration. How long has Toyota been using Drive By Wire? One article was on an 03 Camry. Do the Tundra's use a different DBW system than other Toyota vehicles? Has anyone had issues with sudden acceleration? I am beginning to get concerned. I never liked the idea of a non-mechanical throttle system to begin with. This just solidifies my concerns.
