Common Problems: JAGUAR S-TYPE
Known issues reported by owners and MOT testers.
- ZF 6HP26 Automatic Gearbox "The Lurch" & Mechatronic Sleeve Leak(Moderate)
The 6-speed ZF automatic gearbox suffers from fluid leakage around the plastic mechatronic electrical sleeve and worn valve body damper rubbers, causing harsh downshifts from 2nd to 1st gear when coming to a halt.
- Front Lower Wishbone Rear Hydrobush Fluid Leak & Ball Joint Play(Moderate)
The large fluid-filled hydraulic compliance bushes on the curved front lower control arms rupture and weep black fluid, leading to steering shimmy under braking and MOT failure.
- Sill & Rear Subframe Mounting Corrosion Concealed Behind Plastic Covers(Serious)
Road dirt and wet road salt accumulate behind the full-length plastic sill threshold covers and around the rear subframe front mounting heel boards, corroding structural steel out of plain sight.
