2002 Toyota Sequoia Problems: 6 Known Issues

On the 2001-2007 Toyota Sequoia, 1st-gen Sequoias in salt-belt states develop severe frame rust, particularly at the rear crossmember, rear coil spring mounts, and spare tire carrier area. Following a 2017 class-action settlement, Toyota's Warranty Enhancement Program ZH8 covers frame inspection, replacement if the frame meets the rust-perforation standard, and corrosion-resistant compound application for certain 2005-2007 Sequoias.

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.

On the 2001-2007 Toyota Sequoia 2UZ-FE 4.7L V8, the front suspension lower ball joints on first-generation Sequoias wear out far ahead of normal service life. Toyota's recall documentation attributes it to manufacturing defects - a scratched ball surface (05V225) or improper finishing that lets the internal lubrication deteriorate (07V013) - causing accelerated wear and letting the stud loosen in the housing. Once wear is advanced the stud can pull out of the socket entirely, dropping the control arm and separating the steering knuckle - forum accounts include separations at highway speed. Toyota recalled the front lower ball joints under two separate campaigns: 05V225 covers 2002-2004 Sequoia (alongside Tacoma, Tundra and 4Runner) and 07V013 covers 2004-2007 Sequoia and 2004-2006 Tundra; 2001 model-year Sequoias are not in either recall population. Check your VIN against both. Compounding this, some aftermarket replacement joints (ACDelco and MOOG units built 4/2020-4/2021) were themselves recalled in 2022 for inadequate induction hardening of the housing.

On the 2001-2007 Toyota Sequoia, the retractable rear tailgate glass on the first-generation Sequoia is a chronic failure point. Two distinct causes show up over and over in owner threads. First, a metal stopper/brake bracket and spring assembly inside the hatch binds against the window gear and jams the mechanism - a Toyota TSB addresses this by having the spring and two brackets removed and discarded, which owners describe as fixing hardware that should never have been installed. Second, the window regulator motor itself burns out, often after repeatedly straining against a dry or debris-filled glass run channel. The glass typically stops partway, refuses to go back up, or the switch does nothing at all, and because the hatch cannot be opened with the glass down on some trucks, the failure can leave the vehicle unsecured.

On the 2001-2007 Toyota Sequoia, on certain 2003 model year Sequoias, faulty logic in the Skid Control ECU can fail to correctly store the steering angle sensor center position, so the stability control system never establishes a valid straight-ahead reference. The VSC and TRAC warning lights illuminate and stay on, and vehicle stability control is disabled. Toyota addressed this with a brake service bulletin (BR003-03, VSC Computer Logic Modification for DTC C1231) covering the skid control ECU and the zero-point calibration procedure. The same symptom set recurs across the whole XK30/40 range for a related but different reason worth knowing: any stored powertrain fault automatically disables VSC and TRAC, so a check engine light plus VSC OFF plus TRAC lights very often means the underlying problem is an engine code - frequently the secondary air injection or an O2/wheel speed sensor - not the stability system itself.

On the 2001-2007 Toyota Sequoia 4.7L 2UZ-FE, the cast iron exhaust manifolds on the 2001-2007 Sequoia 4.7L V8 develop cracks from repeated thermal cycling. The cracks typically appear at the flange where the manifold bolts to the cylinder head or between the runner tubes. A cracked manifold causes an audible exhaust leak (ticking noise on cold start that fades as the manifold expands when hot), a faint exhaust smell near the engine bay, and can eventually trigger a check engine light for catalyst efficiency if exhaust gases bypass the catalytic converter.
