The Toyota 2GR-FKS is the dual-injection 3.5L V6 in the Tacoma, 4Runner, Highlander, Camry, RAV4, Avalon, Sienna, and Lexus RX350. It replaced the 2GR-FE and added direct injection. It is one of the most reliable V6s on the road today.
Very reliable. Rubber oil cooler hose is the only widely reported failure. Otherwise, this engine routinely sees 250K+ miles.
Carryover from the 2GR-FE - the rubber oil cooler hose between the block and the radiator can deteriorate and leak. Updated steel-braided replacements are widely available aftermarket.
View diagnosis →Mechanical water pump can develop a slow weep around 100,000-150,000 miles. Easy preventive replacement.
View diagnosis →Toyota included port injectors specifically to keep intake valves clean, so the 2GR-FKS sees far less carbon than VW/Audi DI engines. Inspect at 100K, blast if needed.
View diagnosis →Plastic coolant bypass tube under the intake can crack with age and heat cycling. Symptoms: coolant smell, slow loss, P0128.
View diagnosis →OEM iridium plugs last 100,000 miles but the rear bank requires intake removal, driving up labor.

None - all years are solid
2017+ (any vehicle) - revised oil cooler hose materials
Annual maintenance $400-600. Major service at 100K (plugs, coolant, oil hose) runs $800-1,400. Total non-routine over 200K: $2,000-3,500.

The 2GR-FKS adds D-4S dual injection (port + direct), VVT-iW, and higher compression. Power went from 268 to 295+ hp.
Less than pure-DI engines because Toyota added port injectors specifically to wash the intake valves. Some buildup is normal at 100K+.
With oil changes every 5,000-7,500 miles, plug to 250,000 miles is realistic. Tacomas with this engine routinely cross 300K.
On 2015-2020 models, yes - inspect annually and replace with a steel-braided hose if you see seepage.
