What owners wrote
The 2012 highlander speedometer consistently shows 3 miles over the actual speed, as compare to various highway speed monitors and commercial GPS speed indicators. However, toyota dealer and headquarter said the speedometer is within performance specification. I believe this could be a safety issue as driver may not be sure of the actual speed of the vehicle.
Car has over 117,000 miles and is excessively consuming oil. There is no sign of leaks anywhere. I do not get any warning anywhere about low oil, all I see is a small message that sometimes blinks indicating 'oil pressure'. Oil is not lasting 1000 miles. I thought maybe the oil was not properly filled but after a second oil change, same happened, oil empty with less than 1000 miles after an oil change.
