I have 2010 Toyota Tundra that has had a sudden acceleration. I was driving down the highway with the cruise set at around 73mph. I had to hit the brake, when I hit the cruise to reinstate the cruise the truck seamed like it went full trouble. My foot was never on the gas and the truck accelerated to over 90 before I canceled the curse control. This has happened only once.

2010 Toyota Tundra acceleration when trying to brake. The Tundra could not stop and hit a 2000 Buick which had struck a parked car and catapulted across the lane in front of Tundra (Buick and Tundra going in opposite directions).

Hi, I'm not sure how to address this but I think someone should know. This complaint is somewhat on behalf of a chp officer and family that died and the many others out there like myself, friends and family that have Toyota. I test cars for the California smog check program. I have tested thousands of vehicles both by driving them on a sensitive dynamometer at various speeds and in place at different motor rpms. When Toyota changed to an electronic throttle control on their vehicles it became very noticeable during the smog tests as the vehicle acceleration and control was more sloppy than the previous direct cable method. I worried about this because with no direct linkage and only sensors to interpret your intended acceleration, it could lead to tragic results without proper fail-safes installed. One necessary fail-safe is when you press on the brakes the engine needs to slow to prevent potentially overriding the brakes or create excessive stopping distances. This would prevent many accidents. It is well known in the automotive repair industry that voltage problems, electrical ground problems, or a malfunctioning main computer or poorly written code, will cause other sensors to behave erratically even if the specific affected sensor is not damaged. Vehicle sensors have problems now and then along with corrupted information being sent to those sensors resulting in unintended results. The sensors / linkage involved in Toyota's electronic throttle control are not immune to these problems as Toyota suggests. A mandatory fail-safe needs to be adopted on Toyota to override a potentially faulty electronic throttle. Acceleration complaints have risen sharply since the new throttle system was installed. The difficulty with testing a sensor system is that often it can appear to be functioning fine until the moment it misbehaves or it can act normal while good information is received and then with corrupted information it behaves apart from driver's intentions.

Problem with cruise control not disengaging properly when tapping the brake. The brake must be pressed to the point of actual braking for the cruise control to disengage. There have been several times when while trying to disengage by pressing the brake the engine started to rev up as if I was also pressing the gas pedal. The most reliable was to disengage the cruise control is the control on the side of the steering wheel (main cruise control on my truck). Will be taking the truck to the dealer this week.
