“The new model year 03 and 04 Toyota camry sedans, Sienna mini vans have poorly designed and or mis adjusted headlights causing blinding glare to on coming drivers or drivers in front of these vehicles. The excessively glaring light caused eye pain to other drivers and temporary blindness. This is a serious safety problem that needs to be addressed.”
NHTSA complaint #10051315, filed 2003-12, 1 miles“I am disappointed with Toyota to only have one tether restraint in the 2nd row. So if you have two small children in car seats they both can't be tethered in the 2nd row. Also the placement of this 2nd row tether is terrible! It interfears with the person in the 3rd row, their feet get tangled in the tether. Not safe!!! Dt”
