Steering and Suspension Defects Under Washington Lemon Law

Steering and suspension defects often qualify under RCW 19.118.021’s substantial-impairment test — and steering defects almost always qualify as serious safety defects under RCW 19.118.041(1)(b) with the two-attempt threshold.

Common qualifying steering defects

Loss of power steering assist — categorical serious safety defect.
Steering binding / sticking — serious safety defect.
Steering wander at highway speed — serious safety defect.
Electric power steering (EPS) module failure — serious safety defect.
Steering rack leaks — substantial impairment.
Lane-keep-assist over-correction — substantial impairment; safety defect.

Common qualifying suspension defects

Persistent knocking / clunking — substantial impairment.
Air suspension failures — substantial impairment.
Adaptive damper failures — substantial impairment.
Strut / shock leaks — substantial impairment.
Ride height issues — substantial impairment.
Premature ball-joint or control-arm wear.

TSB / recall overlay

Steering defects are heavily recall-driven:

Power steering module recalls (numerous OEMs).
EPS firmware reflashes.
Lane-keep-assist calibration service bulletins.
Suspension component TSBs.

Pacific Northwest factors

Washington’s road surfaces are highly variable:

Pacific Highway pot-hole stress on suspension.
I-90 / mountain pass driving stress on shocks.
Ferry-route shock absorption (loading/unloading transitions).
Wet-road steering response criticality.

Serious safety defect — two-attempt threshold

RCW 19.118.041(1)(b) — steering defects categorically qualify as serious safety defects:

Two repair attempts sufficient.
Loss of steering assist is paradigmatic SSD.

What strengthens a steering / suspension claim

Symptom consistent across visits.
Recall / TSB pattern.
Alignment specifications out of OEM range.
Independent steering specialist inspection.

What weakens a steering / suspension claim

Pothole damage (driver-induced).
Aftermarket alignment / lowering modifications.
Tire-pressure issues masquerading as suspension problems.
Independent-mechanic visits (don’t count).

Bottom line

Steering and suspension defects are strong Washington cases. Steering defects categorically trigger the serious-safety-defect two-attempt threshold. Document each visit, secure TSB / recall data, and pursue AG arbitration or court action upon meeting thresholds.
