4 faults documented by at least two sources, listed by version then by mileage at onset when known.
4 known faults
Owners report that the rear differential can leak through faulty seals (What Car?). Overtightening the coupling after a repair can also damage the differential, the first sign being a noise from the rear (CarChecker).
The active exhaust valves can stay stuck in the open position, which may require a new rear silencer, often fitted under warranty (What Car?). A technical bulletin describes a squeal caused by partial or total seizing of the valve shaft and its bush, fixed with revised parts.
A weak or discharged battery causes a variety of faults: doors, windows, convertible roof, car not starting (What Car?). Some software updates at the dealer fix a discharge while parked. The CarChecker guide also cites battery discharge at standstill among the main points of concern; on convertibles, roof problems are most often linked to the battery (Autotrader.ca).
NHTSA recall 16V940: the front seatbelt pretensioners may not deploy in a serious accident, increasing the risk of injury. The recall concerns F-Types built from 14 July to 16 December 2016 (2017 model year); dealers inspect and replace the belts free of charge. US recall: check the serial number with a Jaguar dealer. What Car? also reports a recall for faulty pretensioners on cars built in 2016.
Fixed free of charge by a dealer and not counted in the reliability score: ask for proof the work was done (invoice, or a VIN check at a dealer).

An OBD scanner plugged in under the steering wheel shows stored fault codes, even with warning lights off: useful during the test drive.
