2012 Toyota Highlander Problems

Massive Oil Leak and Loss of Oil Pressure

The VVT-i oil line is known to burst. This is a very large leak which covers the ground, engine, and undercarriage.

If the oil line ruptures while driving, the low engine oil message and engine oil pressure warnings will illuminate. Continued use after these warnings will result in complete engine failure due to oil starvation.

The line is known to be defective, and a revised part has been issued by Toyota, however, this revised part is known for the same issue.

To repair the issue, the line must be replaced, and the engine bay and undercarriage must be cleaned thoroughly.

Compressor

Compressor went out on Dec 31, 2009 with about 149K on the vehicle. Dealer replaced the compressor and now it has gone out again with about 164K on the vehicle almost one year later. Was not driving in unusual conditions - just started squealing like a belt or something was loose. With the cost of the part and the labor, it was about $1,000 for the first repair. Am hopeful there is a warranty when I take it in tomorrow.

Incorrect Vehicle Weight Rating Label

Vehicles have a tire size/weight rating label to inform owners of the carrying capacity of their vehicle. These models are being recalled because the incorrect vehicle weight rating is shown on the information label. This could result in vehicle and tire overloading, increasing the risk of tire failure. Owners will be provided an updated vehicle weight label to correct this concern.

Vehicles With Added Seat Accessories May Not Have Properly Functioning Restraint Systems

Vehicles that have had accessories added to the seats such as seat heaters, seat covers or DVD headrests may not have the occupant sensor system of the passenger seat calibrated properly. This can affect passenger air bag operation in a crash. Dealers will test the sensitivity of the occupant detection sensors and recalibrate them as necessary free of charge to resolve the concern.
