Known problems with the 2015 Toyota Highlander
2 of the 5 issues we track for the 2014–2019 generation are documented against the 2015 model year.
2GR-FE water pump coolant leak (2014–2016)
moderateSame known weakness as earlier 2GR-FE Toyotas: the water pump seal weeps coolant, leaving pink residue and eventually dripping. Watch the reservoir level and the weep hole below the pump. Straightforward but labor-heavy replacement on the Highlander's tight engine bay.
Typical cost: $500–$1,200 parts and labor
Power liftgate won't open/close or falls
minorPower liftgate struts and motors wear on XU50s just as they did on the XU40: the gate reverses, beeps and stops, or drifts down. Strut replacement is cheap; a failed power liftgate motor/latch is pricier. Annoying but not a safety issue.
Typical cost: $60–$150 (struts) to $400–$900 (motor/latch)
3 more issues reported in other 2014–2019 years

About the Toyota Highlander
The Toyota Highlander is Toyota's three-row family crossover, and the 2012–2025 span covers three generations with very different powertrains but the same low-drama ownership reputation. 5L 2GR-FE V6 (plus an AWD-only hybrid) with simple port injection, 0W-20 oil, and a Group 24F battery. Its documented weak spots are 2GR-FE water pump leaks and failing power-liftgate struts.
7 and the 2GR-FE, then switched in 2017 to the direct+port-injected 2GR-FKS with an 8-speed automatic and stop-start; that 8-speed drew shudder/whine complaints (TSB T-SB-0160-18), and 2017–2019 models sit inside Toyota's huge Denso fuel-pump recall. 5L hybrid (0W-16 oil) became the volume seller. 3, lug torque is 76 ft-lbs, the key fob takes a CR2032, and gas V6/turbo models tow up to 5,000 lbs with the factory tow package (hybrids 3,500 lbs).
Maintenance is interval-driven Toyota fare: 10,000-mile synthetic oil changes, 30,000-mile air and cabin filters, coolant at 100k then every 50k, and iridium plugs at 120k.
