NHTSA Complaint #11700716 — 2017 JAGUAR F-PACE

My 2017 Jaguar F-Pace S (3.0L supercharged V6) experienced a sudden water-pump failure that led to overheating, loss of oil pressure, timing-chain slack, and complete engine failure. The failure began with the water pump, which caused coolant loss and intermittent overheating that was not accurately reflected on the dashboard temperature gauge. As the water pump deteriorated, the hydraulic timing-chain tensioners lost pressure, allowing the chain to slacken and eventually jump. This caused catastrophic internal engine damage, including piston-valve contact and metal contamination, requiring a full engine replacement. This sequence — water pump failure → overheating → timing-chain tensioner collapse → engine destruction — is known to occur on Jaguar’s 3.0L supercharged V6 engines. Multiple owners have reported similar symptoms (water pump failures, chain rattle, chain slack, engine ticking, and full failure). Jaguar’s own Technical Topics documents acknowledge timing-chain slack due to tensioner issues on these engines. This is a safety defect because the engine can shut down suddenly while driving, which puts the driver and others at risk. My engine failed unexpectedly, without sufficient warning on the instrument cluster, creating a dangerous situation. I request that NHTSA investigate this defect pattern to determine whether a recall or manufacturer action is necessary to prevent further engine failures and safety risks.
