The Toyota Highlander often experiences problems with the engine bolts threads stripping. Engine noise and failed starts on cold days are also commonly experienced problems with the Toyota Highlander.
According to CarComplaints.com, the most common categories for complaints were the interior accessories, engine and wheels. Within interior accessories, common problems included continuous false trips in the alarm system and malfunctioning CD players.
Meanwhile, Toyota Highlander engines experience issues with the engine turning, but not starting. Furthermore, the aforementioned engine bolt threads are prone to stripping, and this problem often results in leaked oil. Malfunctioning timing chains are also a known source for leaking oil in the Toyota Highlander.
The lug nuts on Toyota Highlanders occasionally fall apart, making it impossible to remove the wheel. Another complaint many consumers voiced was difficulty in finding replacement tires. A stock Toyota Highlander features Bridgestone Dueler H/L 400 Quiet Tires, which many dealers do not stock. The tires are available online, however.
The 2008 Toyota Highlander is the most commonly complained about model according to CarComplaints.com. More recent years have received fewer complaints, which indicates that Toyota has taken steps to address many of the concerns voiced about earlier models of the Toyota Highlander.
