Knock, Knock, Knocking on...

2008 Toyota Sienna LE 8-Passenger 4dr Minivan (3.5L 6cyl 5A)
We enjoy the styling and features of this van and it handling. The safety features were a big selling point as well: vehicle stability control, traction control and side curtain air bags. All the glory of the safety ratings and features fade away with the knocking we hear from the engine on cold start up during acceleration between 1500 and 2000rpm. This noisy diesel sound diminishes after the vehicle is completely warms. The dealer said there was nothing wrong with the engine just normal lifter noise to be expected with a vehicle of this mileage. EXCUSE ME!!! Well folks there you have it 47,000 miles is the new high mileage bench mark for Toyota.
Don't make options like daytime running lights mysterious, it only takes a jumper or fuse placed in the correct slot to activate (see any Toyota sienna forum) Step up and acknowledge consumer complaints about engine knocking with a service bulletin or stand behind this design with an extra warranty.
