Why does a car still leave the service bay with lug nuts missing?

A customer's wheel came off three minutes after a dealer oil change and tire rotation because the lug nuts were never put back, and shops still rely on a technician remembering to torque every wheel with no check before the car is released.

What is the “Why does a car still leave the service bay with lug nuts missing?” problem in 2026?

A customer's wheel came off three minutes after a dealer oil change and tire rotation because the lug nuts were never put back, and shops still rely on a technician remembering to torque every wheel with no check before the car is released.

Existing players in this space

  • Tekmetric digital vehicle inspection: Photo checklists for upselling repairs, not a release gate on wheel work.
  • Checkpoint wheel nut indicators: Physical indicators common on trucks, rarely fitted to passenger cars.
  • Data-logging torque wrenches: Record torque values, and only if the technician actually uses them on every nut.

What existing players are missing

A camera check at the bay exit that confirms every lug nut is present on each wheel, matches it against the torque wrench log for that job, and blocks the car's release until a missing wheel is signed off.
