LINDA 
2001 Toyota Highlander SUV 4WD 4dr SUV (2.4L 4cyl 4A)
Lemon or Bad Luck???
 I purchased this vehicle new in 2001.  As much as I would love to say how great this SUV is, it isn't!!!  I do however love everything about it except it's reliability.  Soon after the warranty ran out the engine began to have problems with the check oil light coming on when I checked the oil (which was changed very regularly more often than recommended) it was completely dry on dipstick.  Took it to local Toyota dealer to check for "sludge" as far as they could tell none noted hum!  Continued to drive and add oil before & after long trips.  Not leaking just lots of white smoke. Last week check engine light came on probably need new engine or valve seals? In the shop now. Very disappointed!!
