The most common problems reported with the Toyota Highlander are oil leaks, illuminated airbag lights, and check engine lights.
While the Toyota Highlander is generally praised for its reliability, like any vehicle, there are some common issues that owners have reported over time:
-
Oil Leaks and Loss of Oil Pressure: A frequent issue comes from a defective VVT-i oil line, which can burst and cause significant oil leaks, potentially leading to lower oil pressure if not addressed. It's crucial to monitor oil levels regularly and fix leaks as soon as they arise to prevent engine damage.
-
Illuminated Airbag Light: This issue is usually triggered by a faulty center airbag sensor. The airbag system is vital for safety, so addressing this problem quickly is important to ensure the airbags will deploy properly in the event of an accident.
-
Check Engine Light: Sometimes caused by a hose becoming detached from the air filter housing, triggering the engine light. This can usually be fixed with a quick inspection and reconnection, but ignoring the check engine light can lead to more severe engine problems if the cause is more serious.
These issues don’t affect every Highlander and are not universal across all models or years. However, they are worth keeping an eye on. The good news is that most of these problems are manageable and can be repaired by a DIYer with the right tools and guidance. Having a detailed service manual can provide step-by-step instructions to diagnose and fix these issues on your own, helping you avoid costly trips to the mechanic and keep your Highlander running smoothly.
