Used Lexus RX 350 vs Toyota Highlander: which should you buy?
By Hari Vinayak · Updated 2026-07-03
The short answer
Mechanically cousins, which is the point: the RX 350 gives you the plusher cabin and quieter ride on the same famously durable bones, while the Highlander adds a usable third row for less money. A used RX is one of the safest luxury buys there is — pick by whether you need seven seats.
Model years
2010–2024
Mileage outlook
250,000+ miles is common. An RX with 130,000 documented miles routinely outlasts a German rival with 60,000. Prioritize the service folder over the odometer.
Model years
2008–2024
Mileage outlook
The 3.5L V6 routinely clears 250,000 miles. A 140,000-mile Highlander with dealer records is a safer buy than an 80,000-mile one with none. Hybrids age well too, but ask about hybrid battery health past 150,000 miles.
Lexus RX 350
A used Lexus RX 350 is arguably the most reliable luxury SUV on the market — the 3.5L V6 is the same proven Toyota engine family that runs forever — so the checklist is short: water pump seepage and oil cooler line leaks on 2010–2015 cars, full service history (luxury cars suffer when third owners skip maintenance), and honest pricing, because RX listings carry a badge premium. High-mileage examples with dealer records are genuinely safe buys.
Known issues to check
- 2010–2015: water pump weep and oil cooler line leaks — check the front of the engine and under the car
- Remote-touch infotainment is dated and the mouse controller divides opinion — test it before assuming you'll adjust
- Third-owner neglect: luxury depreciation means some RXs hit owners who skip $300 services — gaps in records matter
- 2016+: very few patterns; check 20-inch wheel/tire condition and panoramic roof drains
What to verify
- Service history continuity — especially recent owners
- Dry water pump and oil cooler lines (2010–2015)
- All power features: tailgate, seats, sunroof
- Price against comps — badge premium invites overpricing
Toyota Highlander
A used Toyota Highlander is one of the most dependable three-row SUVs you can buy, and the known issues are cheap to check: oil cooler line leaks on 2008–2013 V6 models, water pump seepage on the same engine, and a slightly hesitant 8-speed automatic on 2017–2019 cars that is annoying rather than fatal. The bigger risk is price — Highlanders carry a strong reputation premium, so verify the condition matches the asking price.
Known issues to check
- 2008–2013 V6: rubber oil cooler line can rupture and dump oil — check for the updated metal line and any oil loss history
- 2GR-FE V6 water pump weeps coolant with age — look for pink crust around the pump and front of the engine
- 2017–2019 8-speed automatic: low-speed hesitation and clunky shifts — test drive in stop-and-go; software updates improved it
- 2020+ models are largely trouble-free; focus on accident history and dealer service gaps instead
What to verify
- No oil drips under the engine and no oil-loss history (2008–2013)
- Coolant level and water pump area dry
- Smooth low-speed shifting on the test drive (2017–2019)
- Hybrid battery health report past 150,000 miles on Hybrid trims
How to decide between them
On the used market, the better specific car almost always beats the better model on paper. A well-documented Lexus RX 350 can be a smarter buy than a neglected Toyota Highlander, and the reverse is just as true. Build a comp set for each, match the model year to its known issues above, and price in any maintenance the records do not cover.
