I have been driving this van for 8 yrs now without any major problems. The engine and transmission still runs like new. Had oil changed every 3,000 miles (using Synthetic High mile oil after 140,000 miles). It is so smooth and quiet. Replaced Transmission oil every 30K, timing belt/water pump at 120K. Only had a problem (Engine check light) with error code P1135 last week. Replaced with A/F sensor heater (costs me $220 with genuine Toyota part). It might be OK if I should have mechanic to reset it (I regret) because I put emission cleaner to the gas last week. No problem at all so far. Very happy.
