Symptom: At highway speeds the car wanders and needs constant small corrections.
Likely causes
- The EPS tuning. NHTSA's investigation found a steering-feel calibration issue rather than a component failure. Toyota's fix is a retuned power steering ECU, and Toyota Nation owners report better tracking afterward.
- Alignment and tires, which can cause the same feel.
DIY or shop?
Check tires and alignment first (DIY/shop). The ECU swap is done at the dealer.
Useful steps
- Set the tire pressures and get an alignment.
- Ask the dealer about T-SB-0140-10.
