Quick answer

TT: For proper calibration of the millimeter wave radar sensor, the vehicle must be on a level surface. If a level surface is not available, this tech tip should be used in conjunction with the repair manual to set the angle of the front millimeter wave radar sensor and reflector height before performing beam axis adjustment.

What this bulletin may mean before buying

Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.

Frequently asked questions

What is NHTSA service bulletin 10173987?

TT: For proper calibration of the millimeter wave radar sensor, the vehicle must be on a level surface.

How should a used-car buyer use this bulletin?

Use it as a research signal. Compare it with recalls, owner complaints, service records, a VIN report and an independent inspection before buying.
