If you notice a car that drifts on a straight road, capture the exact conditions instead of relying on “it happens sometimes.” Test on a level, safe road and note wind, road crown, braking, and tire pressures. Save the date, mileage, and any warning message.
Repeatable notes help a technician reproduce the concern and distinguish a one-off event from a pattern. Check tire pressure and wear before assuming alignment is needed.
Quick educational note
For information, not a diagnosis or repair instruction. Vehicle-specific checks are still required. Consult the manufacturer's guidance and a qualified technician.
