The car pulls to one side while driving
The vehicle drifts to one side on a flat, straight road without steering input — this generally points to alignment, tire, or a dragging brake rather than a major steering fault.
Possible causes
A wheel alignment out of specification
Uneven or mismatched tire pressure or wear between sides
A dragging brake caliper on one side
A symptom on its own does not confirm which of these is responsible — it narrows the search, not the diagnosis.
Possible causes
A wheel alignment out of specification
Uneven or mismatched tire pressure or wear between sides
A dragging brake caliper on one side
What to check first
Check and equalize tire pressures first — this is the simplest, most common cause
Feel for uneven brake temperatures at each wheel after driving, which can indicate a dragging caliper
Have an alignment check if tire pressure and brakes are ruled out
When to stop driving / seek help
Not urgent unless the pull is severe or sudden, in which case treat it as a possible brake or suspension fault and have it inspected before continuing.
