Find out why the oil line breaks on the Toyota Highlander so much

Looking at some of the Toyota Highlander problems on RepairPal shows fewer issues than the average vehicle. One 

of the most common issues is a massive oil leak or loss of oil pressure. In some Toyotas, the VVT-i oil line is known to 

be faulty. This means that oil can leak all over the Highlander’s engine, ground, and undercarriage, causing 

many issues. If the line ruptures while driving, the low engine oil message and engine oil pressure warning will 

illuminate. This usually means the vehicle won’t run for too long, so it is best to pull over to avoid further damage.
