The PDK dual-clutch transmission in the 718 Boxster can develop mechatronic unit failures affecting shift quality and engagement. Symptoms include harsh shifts, delayed engagement, and occasional refusal to shift into certain gears. The issue is traced to solenoid valve wear in t… Repairs typically run $2,500-$6,000. Severity: high.
EU-spec (and later global) 718 four-cylinder cars fitted with a gasoline particulate filter (German: Ottopartikelfilter/OPF) have suffered premature clogging and outright filter failure.

The turbo flat-four engine in the 718 Boxster develops coolant leaks at the turbocharger water line connections and the coolant distribution housing. The plastic housings crack from thermal cycling, causing slow coolant loss that can lead to overheating if not caught early. Repairs typically run $500-$1,500. Severity: medium.
As the turbocharged flat-four ages and is subjected to high underbody heat, the engine's oil seals degrade and weep oil. The most significant is the rear main seal between the engine and transmission, which produces an oily film and drips at the bellhousing area; valve-cover gask… Repairs typically run $400-$1,800. Severity: medium.
Owners of the 6-speed manual 718 Boxster report a grinding/balking sensation when shifting from 1st to 2nd gear, particularly during cooler, low-rpm shifts before the gearbox warms up. The 2nd-gear synchro is most affected; the grind rarely occurs above roughly 3,300 rpm or betwe… Repairs typically run $150-$3,000. Severity: medium.
The engine-driven coolant pump on the turbocharged flat-four 718 (shared design lineage with the 991.2 911) is a known weak point.

Symptoms include an oily film/drips under the car, oil residue on the… Repairs typically run $300-$2,500. Severity: medium.
The air-oil separator (crankcase breather/oil separator) on the turbocharged flat-four 718 can fail, causing excessive crankcase vacuum that draws engine oil into the intake. Owners report white/blue smoke (especially at startup or under acceleration), an oil smell, fouled spark… Repairs typically run $400-$1,200. Severity: medium.
The air-oil separator, which manages crankcase ventilation and returns oil vapor to the intake, can fail on the 718's flat-four.
