Why it's a good car
The 2015 Highlander is part of the third generation (2014–2019). The engine to want is the strong, proven 3.5-liter V6 with a conventional six-speed automatic and a timing chain — a genuinely long-lived combination (a base 2.7-liter four-cylinder was also offered, but the V6 is the one to have). It's roomy, comfortable, holds its value well, and consistently earns excellent reliability ratings. There is no systemic drivetrain failure to worry about.
Does it have a timing belt or a timing chain?
A timing chain on the V6, so there is no timing-belt interval or scheduled timing service to budget for.
What actually goes wrong
Genuinely little, and the complaints skew to electronics rather than the drivetrain:
- Infotainment and electrical The most-cited items — audio, navigation, and display freezing or rebooting, plus assorted electrical faults. Test every screen and feature.
- Minor items Occasional A/C, heater, or noise complaints; nothing that defines the vehicle.
Open recalls — check the VIN, it's free
The 2015 Highlander's recall history is light (a power-steering item among them), but recalls are VIN-specific — you cannot assume the status from the model year. Look up any 2015 Highlander's open recalls free by VIN at the U.S. National Highway Traffic Safety Administration (NHTSA); a Toyota dealer completes any open recall at no charge.
What a history report tells you — and what it doesn't
On a car like this, the individual car's history is most of the decision. A history report is a record of what got reported — title brands, reported accidents and damage, odometer readings over time, and service records where they exist. That is what separates a clean, maintained example from a salvage-title or flood car wearing the same badge.
What a history report is not is a forecast, and an absence of records is not proof of a clean past — plenty happens to a car that never gets reported. That is why the honest answer is always the pair: the documented history and an in-person inspection by a mechanic you trust, on the specific car.
The things to check before you buy
- Which engine The V6 is the one to want; confirm it if long-term durability and resale matter to you.
- Infotainment and electrical Test the screen, audio, navigation, and cameras for freezing or faults.
- Recall status Confirm any open recalls are completed on this VIN.
- Maintenance history Consistent oil and fluid services.
- Accident and rust Sight down panels in raking light; on salt-belt cars, look underneath.
What would make you walk
- Poorly repaired structural damage Mismatched paint, uneven gaps, or ripples in the roof or pillars.
- Neglect with no records A drivetrain this durable still needs its services; no history changes the price.
- Structural rust Perforation at the subframe or floor pans on a salted car.
