Engine components in a service bay

Powertrain protection

Powertrain protection is the plan drivers choose when they want the expensive mechanical core of the vehicle covered and they are willing to handle wear items themselves. It is also the plan we recommend when an odometer is too high for exclusionary coverage but the engine and transmission still have a service record.

The schedule pays for a covered mechanical failure of named internal parts, the labor to diagnose and replace them, and the fluids and seals required to complete that repair. It does not pay for a tune-up, a timing belt that is due by mileage, or a failure caused by running the engine out of oil.

Engine diagnostics and covered assemblies

A claim starts with a diagnosis, not with a parts order. The workshop identifies the failed assembly and the cause. Typical covered engine assemblies include:

  • Pistons, piston rings, pins, and connecting rods
  • Crankshaft, main bearings, and rod bearings
  • Camshaft, lifters, and timing chain when it fails, not when it is due
  • Oil pump, balance shaft, and engine block if damaged by a covered failure
  • Cylinder head, valves, and valve guides, excluding carbon cleaning
  • Transmission and transfer-case internal gears, pumps, and shafts
  • Drive axle shafts and differential internals listed on the schedule

How a powertrain claim is decided

Send the estimate, the odometer, and photos of the failed part if the case has already been opened. An advisor compares the line items with the schedule. If the failure is covered, you receive a written approval with the deductible and any betterment for a part that was already worn. If it is not covered, the note cites the exclusion, such as lack of lubrication, contamination, or a modification that changed the assembly.

What you keep on file

Oil and filter service within the interval printed in the agreement, cooling-system service when the schedule requires it, and any transmission fluid service named on the plan. Receipts should show the date, the odometer, and the work performed. A gap in service does not automatically void an unrelated covered failure, but a failure caused by that gap is not eligible.
