It has happened twice too me truck is running fine and then check engine light comes on truck goes into a limp mode . Has done it twice once running about thirty miles per hour the second time running 70 mph in busy I-10 traffic in jax FL rush hour bad news. Truck never shuts off goes to a idle speed and will not run over 20 miles per hour maybe if you lucky . No throttle response it will only have a idle . Never shuts off .
Heard humming noise from front end and took my truck to my mechanic who found excessive play in the front wheels. He said the wheels could come off and that it was dangerous to drive. He replaced both wheel bearing and hub assemblies. Test drive confirmed diagnosis.
High idle, truck wanting to run on at a higher rpm when shifting. Idle not dropping down between shifts. Excessive high idle when in second gear going down an incline, when motor should be at idle speed. Dangerous on snow/ice when you use the engine torque to slow the vehicle. Seems to be a iac (idle air control) issue, computer controlled. Having worked for a foreign car company for 16 years as a district service manager, I find this an odd problem, as the computer knows the car is warmed up, but continues to hold the iac valve open, causing a high idle. It appears to be a control (computer) issue.
Several Toyota models, including my 2008 Tacoma experience premature front wheel bearing and hub failures. Incidences have been reported for these models as far back as 2002 and the issue has not been resolved by Toyota. The failure in my vehicle was caught before becoming catastrophic, but as you might imagine, a front wheel bearing failure at high speed can be a devastating accident. This first failure on my vehicle was resolved at my expense in excess $800, but internet reports suggest this repair is not a fix. It is probable that this will occur again as Toyota has not fixed the problem, but is making repairs at the consumers cost. Please have Toyota stand behind their engineering failures.
