Category analysis
Where warranty value can appear
An internal engine failure is the repair scenario most likely to make a service contract look useful on dollars alone. It is also a claim category where maintenance records receive close attention.
The 5 benchmarks in this category put parts between $338 and $12,000.
Modeled labor ranges from 1.6 to 28 hours. At the $148 median metro rate, that is roughly $236 to $4,133 before parts.
Check exclusions for overheating, sludge and missed service. An engine can appear on the covered list while the documented cause of failure sits outside it.
