Body computer failed disabling the emergency flashers, turn signals, tach, speedometer, air bags, ABS,stability control, and rendering the truck's controller area network (can-bus) network unusable for normal and emergency needs. Engine would run, transmission would shift, but the safety features of the tundra appeared to be disabled along with the flashers, turn signals, tach, and speedometer which were inoperative. I live near houston and toyota has this part on backorder nationwide indicating this failure may be common with this and maybe other tundra trucks. When the body computer fails the truck is unsafe to drive yet it can be driven!
2010 Toyota Tundra electrical complaints
Page 2 of 2: complaints 11 to 16 of 16, newest first, as owners wrote them.
Door locks will not lock. Just unlock. Even from inside of the truck you can not lock them. It has done this before. Now its all the time.
Vehicle was traveling in freeway and all of a sudden the a/t oil temp light came on and the vehicle stop right away. Engine and everything stop working. I think this is serious and too dangerous. Hope someone will investigate the issue.
Sticky master passenger power window switch / smell of burning plastic. Upon inspection passenger master power switch had melted.
I have a unattended acceleration problem it has now happened 4 times 3 time after the recall the latest time was today.
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 toyotas. 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 toyotas 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.
