Toyota Tundra 2007 w/ 4wd. Vehicle went from normal 2 wheel drive into 4 wheel drive low without warning, without touching any controls. Could not drive faster than 30 mph, engine check light came on. Turned into dealer, they said it was a component in the engine that failed. The warranty inspector came by today and the history data on the memory had been erased and could not duplicate. Vehicle is still in the shop. Dealer states it is defective but the warranty does not want to pay for the repair. The dealer stated air pump in the intake manifold failed. The consumer believe the problem may be the ecu.
