The Toyota Highlander is one of the most popular three-row family SUVs on Oklahoma roads — spacious, reliable, and well-suited to Coweta families with kids in soccer, teens learning to drive, or grandparents who need comfortable seating for everyone. Like all Toyota products, it rewards consistent maintenance with exceptional longevity. This guide covers what Highlander owners should watch for by generation and what keeps this SUV running well for 200,000+ miles.
Most Common Toyota Highlander Problems
2nd Generation (2008–2013) — 2.7L 4-Cyl and 3.5L V6
- Oil consumption (2.7L 2AR-FE engine): The 2.7L 4-cylinder shares the same oil consumption concern as the Camry 2AR-FE. Monitor oil level monthly; consult with your mechanic about Toyota’s extended coverage TSB.
- Excessive oil consumption (some 3.5L V6 units): Less common than the 4-cyl but reported in some 2008–2010 units. Check oil at every fuel fill for the first 1,000 miles after an oil change to establish your consumption rate.
- Rear strut wear: Rear struts on 2nd-gen Highlanders commonly wear between 90,000–130,000 miles. Symptoms: rear bounciness, reduced handling stability when loaded. Replacement cost runs – at an independent shop.
3rd Generation (2014–2019) — 2.7L 4-Cyl and 3.5L V6
- Fuel pump module failures: Some 2014–2016 Highlanders experienced fuel pump module failures. Toyota issued a recall — check your VIN at Toyota’s recall database.
- Infotainment system issues: The Entune system on this generation has known reliability issues including Bluetooth connectivity, screen freezing, and slow response. Toyota issued several software updates; software update through a dealer is the first step.
- TPMS sensor battery failure: As sensors age past 6–8 years, TPMS warning lights appear. Sensor replacement is required.
4th Generation (2020–Present) — 2.5L 4-Cyl Hybrid and 3.5L V6
- Hybrid battery warranty: The Highlander Hybrid comes with an 8-year/100,000-mile hybrid battery warranty (10 years in California-spec states). Oklahoma drivers: the standard 8-year coverage applies. Monitor for high-voltage battery health warnings.
- Squeaky brakes at low speed: Common in many 2020–2022 Highlanders. Toyota released updated brake pads to address the cold-weather squeal. Ask about updated pad spec during your next brake service.
