Pre-restyle X80 (2017) known issues

Tags: #sunroof · #springs · #head-unit · #parking-brake · #buying-guide

The community has documented a recurring list of issues specific to the pre-restyle X80 (2017 and earlier), most of which were addressed on the restyled (2018+) model:

1. Sunroof drain-tube corner design defect: the pre-restyle sunroof drain tubes use plastic corner fittings with a flawed design at the drain-tube angle/elbow — it's not that the tube "pops off," but that the corner-fitting geometry itself is wrong, causing water leaks into the cabin over time. The restyled model corrected this specific design flaw ¹²³⁴. Remedy reported by the community: replace the plastic elbow/hose with a silicone equivalent or apply sealant at the joint.
2. Front springs settle/sag over time and may eventually break, requiring replacement — see the dedicated suspension-wear card for detailed spring-life data across driving styles ¹⁴.
3. Touchscreen head unit overheating: the pre-restyle touchscreen unit (where fitted) lacks adequate cooling and is prone to overheating and burning out ¹⁴.
4. Parking-brake glitches are commonly reported on pre-restyle cars ¹⁴.
5. Wheel-arch trim strips work loose over time, which can allow water into the interior along the arch line ¹⁴.
6. Engine valves require periodic manual adjustment, since the pre-restyle engine lacks hydraulic valve-lash compensators (hydraulic tappets) — this is routine maintenance rather than a defect, but it's an extra service item pre-restyle owners should budget for that restyle-engine owners generally don't need to worry about ¹⁴.
