Vsa Warning Light On problems of the 2008 Toyota Tundra

The vehicle had been sitting in the driveway overnight. When I got in to go to work in the morning several warning lights were illuminated. The slip, brake, 4x4 hi and lo, vehicle stability control, and lsd lights stayed on until I stopped and turned the vehicle off and then back on. When I restarted the vehicle the lights were out. This has happened six times in the past 12 months. Two other times the brake light was on and stayed on until I turned off the vehicle and restarted. There has never been an acceleration issue. On two occasions, while driving on a dry road the traction control engaged and took the power out of the vehicle. On both occasion was driving in town at less than 30 mph. The local dealership has never been able to duplicate the fault.

On my 2008 Tundra while pulling a travel trailer on occasion the check engine light comes on along with the vehicle stability control and traction control lights. The last occasion was while on a return trip a little over half way back home the lights came on after a brief stop. After about two days the lights go out. This is the 3rd or 4th time this has happened. I took the truck to the dealer to have it checked out and they said that because I had a after market oiled air filter on the truck it was contaminating the mass air flow sensor, and refused any further service because of the modification, and said that there were not any codes in the history of it happening before. After getting back home I pulled the mass air flow sensor out and there was not the first bit of oil residue at all on the sensor. I believe that since the truck is still under warranty they did not want to go it any further and to just blame it on the after market air filter which has proven to not cause the problem.
