The 2011 Sequoia is built on Toyota's proven full-size platform, but the 5.7L V8 has a catastrophic piston ring and carbon buildup problem that can grenade motors. The 4.6L is more reliable but underpowered for this 5,800-lb truck.
5.7L V8 Piston Ring Failure and Carbon Buildup
Common · high severity
Typical onset: 80,000-150,000 mi
Symptoms: Excessive oil consumption (1+ quart per 1,000 mi), Blue smoke on cold start, Carbon buildup causing rough idle and misfires, Check engine light with misfire codes P0300-P0308
Fix: Toyota TSB ZE3 addressed this with piston/ring replacement, but many engines need complete rebuilds or short blocks by now. 25-35 labor hours for engine-out service, rings, decking, and reassembly. Some owners opt for reman long blocks to avoid repeat failures.
Estimated cost: $6,500-12,000
Transmission Oil Cooler Line Corrosion and Frame Rust
Common · high severity
Typical onset: 60,000-100,000 mi
Symptoms: Red ATF puddles under vehicle, Transmission overheating warnings, Cooler lines corroded where they touch the frame, Frame rust near rear suspension mounts in salt states
Fix: Cooler lines run along the frame and corrode through from contact and road salt. Replace both lines (don't just patch one) and inspect frame for structural rust — Toyota had a frame recall on Tundras, but Sequoias weren't included despite sharing the platform. 3-5 labor hours for lines; frame repair is chassis-dependent.
Estimated cost: $800-1,500
Air Injection Pump Failure
Occasional · medium severity
Typical onset: 100,000-140,000 mi
Symptoms: Check engine light P0418, P0419, P2440-P2444, Loud squealing or grinding from engine bay on cold start, Failed emissions test in states that check OBD monitors
Fix: The secondary air injection pump seizes or the valves stick. Pump is on driver side of engine. Some techs delete the system in non-emissions states, but proper fix is pump and valve replacement. 2-3 hours labor.
Estimated cost: $1,200-1,800
Steering Rack Leaks and Power Steering Hose Failure
Occasional · medium severity
Typical onset: 90,000-130,000 mi
Symptoms: Power steering fluid leaks at rack boots, Groaning when turning at low speeds, Hard steering or wandering at highway speed, High-pressure hose weeping at crimp fittings
Fix: Rack seals leak, and the high-pressure hose is known for failing at the crimped ends. Toyota issued TSB for steering rack on this platform. Rack R&R is 4-6 hours; hose replacement is 1.5 hours. Do both if rack is out.
Estimated cost: $1,400-2,200
Front Seat Heater Element Failure
Occasional · low severity
Symptoms: Heated seat turns off after 5-10 minutes, Seat heater warning light on dash, Open circuit codes in Toyota scan tool
Fix: Heating element grid breaks in the seat cushion. Toyota had multiple recalls for seat heaters (NHTSA recalls due to fire risk), but many fail outside recall scope. Requires seat removal and upholstery work. 3-4 hours per seat.
Estimated cost: $600-1,000
Exhaust Manifold Stud Corrosion and Leaks
Common · low severity
Typical onset: 70,000-110,000 mi
Symptoms: Ticking noise from engine bay on cold start, Exhaust smell in cabin, Visible soot stains on manifold, Failed emissions visual inspection
Fix: Manifold studs corrode and snap, causing exhaust leaks. Worse in salt-belt states. If caught early, extract studs and re-torque. If neglected, manifolds warp and need replacement. 4-6 hours per bank on the 5.7L (tight engine bay).
Estimated cost: $800-1,800
Owner tips
If buying a 5.7L, get a pre-purchase compression and leakdown test — oil consumption issues start before visible smoke
Check frame and brake lines for rust if vehicle spent time in salt states; corrosion can be severe by 100k miles
Change ATF at 60k intervals even though Toyota says 'lifetime' — these transmissions run hot towing
Keep up with carbon cleaning (intake valve walnut blasting) every 60-80k on 5.7L to prevent misfires
Buy a 4.6L or a low-mileage 5.7L with documented piston service — the engine failures are expensive enough to total an otherwise solid truck.

AIR BAGS:FRONTAL:SENSOR/CONTROL MODULE-INACTIVE · 13V014000
2013-01-16
Southeast Toyota Distributors, LLC (SET) is recalling certain models interspersed through model years 2009 through 2013 as follows: model year 2009-2012 Tacoma, 4Runner, Camry, Camry Hybrid, Prius, and RAV4; model year 2009-2010 Avalon, FJ Cruiser, and Highlander Hybrid; model year 2010-2013 model year Corolla, Sienna and Tundra; model year 2009-2013 Highlander and Venza; model year 2012 Prius V; and model year 2010-2012 Sequoia. During modification by SET to include accessories such as leather seat covers, seat heaters or headrest DVD systems, these vehicles may not have had the passenger seat occupant sensing system calibration tested. Without passing the calibration test, the occupant sensing system may not operate as designed.
Consequence: If the front passenger seat occupant sensing system is out of calibration, the front passenger airbags may not deploy or they may deploy inappropriately for the passenger's size and position. This could increase the risk of personal injury during the event of a vehicle crash necessitating airbag deployment.
Remedy: Southeast Toyota will notify owners, and dealers will test the sensitivity of the occupant detection sensors, and recalibrate them as necessary. The recall began on March 21, 2013. Owners may contact Southeast Toyota at 1-800-301-6859.
TIRES:PRESSURE MONITORING AND REGULATING SYSTEMS · 11V148000
2011-03-04
TOYOTA IS RECALLING CERTAIN MODEL YEAR 2008 THROUGH 2011 FJ CRUISER, LAND CRUISER, TACOMA, SEQUOIA AND TUNDRA VEHICLES FOR FAILING TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 138, "TIRE PRESSURE MONITORING SYSTEM (TPMS)." WHEN FACTORY-INSTALLED WHEELS AND TIRES WERE REPLACED WITH TOYOTA AUTHORIZED ACCESSORY WHEELS AND LT TIRES PRIOR TO FIRST SALE, THE TIRE PRESSURE MONITORING SYSTEMS WERE NOT RE-CALIBRATED CORRECTLY AND THEREFORE DO NOT START ILLUMINATING THE LOW TIRE PRESSURE WARNING TELLTALE AT THE REQUIRED MINIMUM ACTIVATION PRESSURE.
Consequence: FAILURE TO WARN OF TIRE DEFLATIONS IS A NON-COMPLIANCE WITH FMVSS 138 AND COULD LEAD TO TIRE FAILURE INCREASING THE RISK OF A CRASH.
Remedy: FOR THE LAND CRUISER, SEQUOIA, TACOMA AND TUNDRA VEHICLES, THE DEALER WILL RE-CALIBRATE THE TIRE PRESSURE MONITORING SYSTEM ON AFFECTED VEHICLES AND INSTALL AN UPDATED TIRE AND LOADING INFORMATION LABEL AT NO CHARGE. FOR THE FJ CRUISER VEHICLES, THE TPMS CANNOT BE RESET SO THE ELECTRONIC CONTROL UNIT (ECU) FOR THE TPMS WILL BE REPLACED. TOYOTA IS CURRENTLY DEVELOPING THE REMEDY ECU. IF AN OWNER IS NOT CERTAIN WHETHER HIS OR HER VEHICLE IS EQUIPPED WITH THESE ACCESSORIES, PLEASE CONTACT ANY TOYOTA DEALER FOR AN INSPECTION AT NO CHARGE. THE SAFETY RECALL BEGAN ON MARCH 31, 2011. OWNERS MAY CONTACT TOYOTA AT 1-800-331-4331.
