NHTSA Complaint #11717874 — 2017 HONDA PILOT

Component/System Failed: Engine – Excessive oil consumption (piston rings / internal engine components). The vehicle is available for inspection upon request. Description of the Problem: The engine is experiencing excessive oil consumption. During a monitored oil consumption test, approximately 0.9 quarts of oil were consumed over about 1,006 miles, which equals a consumption rate of approximately 1 quart per 1,118 miles. This rate is abnormally high and indicates an internal engine defect, likely related to piston rings and/or sealant failure. Safety Risk: Excessive oil consumption creates a significant safety risk. If the oil level drops too low between oil changes, it can lead to engine failure, sudden loss of power while driving, engine seizure, or stalling. This could place the driver and others at risk, especially at highway speeds or in traffic. There was no visible oil leak. The oil is being burned internally. Inspection / Confirmation: The issue has been monitored through an oil consumption test. Dealer diagnosis indicates internal engine repair is required (piston and seal-related repair). Estimated repair cost is approximately $6,000. Warning Lamps or Prior Symptoms: No external oil leak was present. Oil level dropped significantly between checks. (If applicable, add: “Oil warning light did/did not illuminate.” If unsure, write: UNKNOWN.) Manufacturer / Other Inspections: Vehicle has been inspected by dealership service department. (If Honda corporate has been contacted, add that here.) Additional Information: The repair cost is excessive for a defect involving internal engine components and appears to be a known oil consumption issue.
