Toyota Sequoia
5.7L V8 with 381 hp — Toyota's last big V8 in trucks. Cam tower oil leak is the known concern: RTV sealant ages, oil drips onto exhaust manifold. No recall despite widespread occurrence. Otherwise rock-solid, 250k+ mile lifespans documented.
5.7-liter V8 — no hybrid needed
The 3UR-FE turns the Sequoia XK60 into a serious machine for heavy hauling. 386 hp and a sonorous V8 rumble — when towing needs reach 8,500 lbs, this engine answers without complaint. Fuel economy is poor, but the driving experience is timeless.
Engine Weaknesses 6
Emission system valves corrode stuck. Vehicle throttles to ~30 mph. Especially early 2nd Gen (2007-2010) in humid climates.
Symptoms: Check engine light, drastic power loss, limp mode
Nearly universal on 2007-2013: moisture intrusion into pump, codes P0418/P2440-P2443. Toyota warranty extended to 10yr/150k for 2007-2010. Dealer repair $2-3.5k, Hewitt Tech bypass kit ($300-500) is the community fix.
Symptoms: Check engine light, power loss, worse fuel economy
RTV sealant between cam tower and cylinder head ages and fails. Oil drips onto exhaust manifold — fire and smoke risk. Toyota has not issued a recall. 20 labor hours at the dealer.
Symptoms: Oil smell/smoke from hood, oil stain up front, burning odor
2008 model year particularly affected. Regular top-ups needed, sustained low levels can cause camshaft damage.
Symptoms: Oil level warning, frequent top-ups
Cast-iron manifolds crack from heat cycling, especially driver side. Cold-start tick that fades when warm. Broken studs add labor.
Symptoms: Ticking on cold start, fades when warm, sometimes exhaust smell
Water pump weep hole seepage. Should be inspected/replaced at timing chain service.
Symptoms: Coolant loss, temperature rising

The 3UR-FE V8 in the Sequoia XK60 is notorious for secondary air injection pump failures. Moisture enters the system, blocking the switching valves and destroying the pump. Error codes P2440/P2441/P2442, limp mode possible. Toyota extended the warranty on 2008–2010 models to 10 years / 150,000 miles (TSB POL 11-05). Repair cost $1,600–$4,000.
2018–2019 Sequoia XK60: the Denso low-pressure fuel pump can block and stall the engine. NHTSA campaign 20V-012 — free pump replacement at dealership.
Early XK60 models (2008–2013) in rust belt regions show frame and underbody corrosion earlier than expected. The Sequoia's higher weight vs. Tundra places more stress on corroded frame members. Inspect the frame and brake lines before buying any used XK60.
Toyota filed a voluntary Equipment Recall with NHTSA in December 2021 for defective power steering gear assembly service parts used in 2008–2022 Sequoia (and 2007–2021 Tundra). A manufacturing defect allows power steering fluid to leak — if significant fluid is lost, steering assist can suddenly fail.
Owners report early rotor wear under 40,000 miles, especially on 2016+ models. The Sequoia's 6,200 lb curb weight puts heavy demands on stock rotors. Upgraded rotors are recommended for owners who tow or frequently load the vehicle.
The Sequoia XK60 HVAC blend door actuator fails over time, preventing temperature control on one or both sides. The part itself is inexpensive, but labor is costly because access requires partial dashboard disassembly.
