On the 2008-2022 Toyota Sequoia, the load-leveling rear air suspension on the Sequoia (Limited and Platinum trims) suffers from compressor burnout and air spring leaks. The compressor runs excessively to compensate for slow leaks in the air springs, eventually overheating and failing. The rear of the vehicle sags overnight or after extended parking.

Common Symptoms

Rear of vehicle sagging after parking overnight
Compressor running continuously
Suspension warning light on dashboard
Harsh ride quality over bumps
Uneven ride height side to side

How to Fix

Replace the air compressor and both rear air springs as a set. Many owners convert to conventional coil springs using a conversion kit, which eliminates the air suspension entirely and costs less long-term. Arnott and Strutmasters offer bolt-in conversion kits.

On the 2001-2009 Toyota Sequoia 2UZ-FE, the 4.7L 2UZ-FE's secondary air injection system fails due to corroded air switching valves (ASVs) and seized air pumps. Moisture enters the system and corrodes internal components. Causes check engine light with P2440/P2442 codes.

This issue also affects: Toyota 4Runner, Toyota Tacoma, Lexus GX

Common Symptoms

Check engine light with P2440 or P2442 codes
Rough idle on cold start
Ticking or buzzing noise from air pump on startup
Failed emissions testing

How to Fix

Replace air switching valves (Toyota 25701-50040 and 25702-50011) and air injection pump (Toyota 17610-0S010) if seized. Many owners bypass the system entirely with block-off plates since it only operates during cold start for emissions. Bypass plates available from Trail Gear or fabricated from aluminum.

On the 2008-2019 Toyota Sequoia 5.7L 3UR-FE, 2nd-gen Sequoias with the 5.7L 3UR-FE also suffer from secondary air injection pump failures, similar to the 1st gen but with updated part numbers. The pump seizes from internal moisture corrosion, triggering P2440-P2445 codes and check engine light.

This issue also affects: Lexus LX, Toyota 4Runner, Toyota Tacoma

Common Symptoms

Check engine light with P2440-P2445 codes
Loud buzzing or grinding on cold start
Air pump not engaging on startup
Failed emissions test

How to Fix

Replace secondary air injection pump (Toyota 17610-0S010 or Dorman 306-058). Replace air switching valves if corroded. Aftermarket pumps are available at lower cost. Some owners install check valves in the air line to prevent moisture backflow into the pump.

On the 2001-2022 Toyota Sequoia, the gas-charged struts that hold the rear liftgate open on the Sequoia lose pressure over time, causing the heavy rear hatch to fall on its own. This is a safety concern as the liftgate is large and heavy enough to injure someone if it drops unexpectedly. The struts typically begin to weaken after 5-7 years and fail completely within 8-10 years. Cold weather accelerates the failure as gas pressure drops with temperature. Both first-generation (2001-2007) and second-generation (2008-2022) models are affected.

Common Symptoms

Rear liftgate will not stay open on its own
Liftgate slowly drops when released
Liftgate falls quickly when opened — safety hazard
Need to prop liftgate open with a stick or arm
Liftgate harder to lift than when new

How to Fix

Replace both rear liftgate struts at the same time — they are sold in pairs for $30-$80. Installation takes 10-15 minutes with no tools required on most models (the struts pop on and off ball studs). OEM Toyota struts are available for $40-$60 each, and aftermarket options from Stabilus, StrongArm, or Sachs run $15-$30 each. Always replace both struts even if only one has failed — if one is weak, the other is close behind. This is one of the easiest DIY repairs on the Sequoia.

TipThis is a 10-minute DIY repair. The struts pop off the ball studs with a flat-head screwdriver. Buy a pair from Amazon for $30-$50 and replace them yourself. No tools or jack needed.
