There are 1 owner-reported powertrain & transmission complaints for the 2019 Jaguar XJin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Our 2019 Jaguar XJ only has 41000 miles on it but it has a poorly designed cooling system: Hoses for the cooling system travel directly under the super charger assembly and are not designed to stay intac for anywhere near our 100,000 mile Warranty but are NOT covered by warranty. This, I would argue is a definitive safety issue with the fumes that are produced and the leakage from the pink hybrid coolant. Also, the available replacement parts are metal piping as opposed to the inferior plastic installed by the manufacturer, which seems intentional due to the high cost FOR REPLACEMENT born by the consumer. Due to the frequency reported by consumers for this issue this should have been classified as a recall because of the engine failures that have most certainly taken place, which pose MULTIPLE other safety issues as well.
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
