2018 Toyota Highlander: True Cost of Ownership (5-Year Breakdown)
The 2018 Toyota Highlander is a three-row midsize SUV that blends family-friendly practicality with Toyota's legendary reliability, making it one of the most popular used SUV choices on the market. At around $25,000, it hits a sweet spot for buyers who want seating for seven or eight without the running costs of a newer model. It's especially well-suited for suburban families, road-trippers, and anyone prioritizing long-term dependability over flash.
Monthly cost breakdown
The 2018 Highlander holds its value exceptionally well for a used midsize SUV — Toyota's brand reliability keeps residual values strong, and you can expect to retain roughly 55-60% of a $25,000 purchase price after five more years of ownership. Its desirability in the used market means resale demand remains consistently high.
Pros
- Toyota's reputation for reliability keeps unplanned repair costs well below the midsize SUV average — industry data puts annual repair costs around $489/year
- Strong resale value means depreciation costs are more predictable and less punishing than many competitors like the Ford Explorer or Dodge Durango
- Insurance rates are moderate for a three-row SUV thanks to solid safety scores and Toyota's lower claim frequency
- Fuel economy of roughly 20 city / 27 highway mpg for the V6 is competitive for the class, keeping annual fuel costs manageable at ~12,000 miles/year
Cons
- The 3.5L V6 requires premium-grade oil and slightly more attentive maintenance than smaller engines to avoid the known oil consumption issue
- At $25,000 you're likely getting a base or LE trim with fewer features, meaning ownership experience may feel dated versus newer competitors
- Tire replacement costs are higher than average — the OEM tire size (245/60R18 or 245/55R19 depending on trim) runs $175–$250 per tire
- Fuel costs add up faster than hybrid alternatives; the non-hybrid Highlander cannot match the efficiency of rivals like the Kia Sorento Hybrid or Toyota's own hybrid version
Common problems to watch for
- Oil consumption issues on the 3.5L V6 engine — worth checking oil levels between changes and reviewing service records before purchase
- Water pump failures have been reported on some V6 models around 80,000–100,000 miles, budget for a potential $400–$600 repair
- Infotainment and Entune system can be laggy or glitchy; software updates help but it's a known weak point for the generation
- Brake wear tends to run faster than average due to the SUV's curb weight of roughly 4,500 lbs — budget for pads and rotors every 40,000–50,000 miles
- Transmission shudder at low speeds has been reported on some units, often resolved with a fluid flush but worth a pre-purchase test drive
The verdict
From a cost-of-ownership standpoint, the 2018 Toyota Highlander at $25,000 is a genuinely smart buy — its below-average repair costs, strong resale value, and reasonable insurance rates make the all-in monthly cost competitive for a three-row SUV. The main watch-outs are the V6 oil consumption tendency and the aging infotainment system, but neither represents a dealbreaker if you buy a well-maintained example with service records. For a buyer who plans to keep the vehicle 4–6 years, this remains one of the safer used SUV investments in its class.
Best for: The 2018 Toyota Highlander is best for families of five to eight who prioritize reliability and low long-term repair costs over cutting-edge tech or maximum fuel efficiency.
