Porsche Carrera
The DKCA is the consistent evolution of the MA2 — same 3.0-litre biturbo architecture, but with GPF particulate filter and slightly revised boost control. Early vehicles from the first production year 2019 had structural manufacturing issues: the active engine mounts (PADM) were insufficiently sealed — water ingress destroys the sensor. Porsche provided revised mounts, but replacement requires engine removal. Second known weakness of early batches: water pump failure at very low mileages. From model year 2021 both problems are largely eliminated. The ignition coil issue is cross-generational — heat stress from the rear-mounted position; replacing all six coils at once is recommended. Mechanically solid otherwise, provided the service history is complete.
Maximum comfort, minimum tension
The most complete comfort package among the 992 Carreras: AWD, PDK, convertible, biturbo. Safe in any weather, relaxed on long journeys, completely without excitement. A good car — not a thrilling Porsche.
Engine Weaknesses 6
Early 992 production batches (late 2019, early 2020) had faulty water pumps. Porsche supplied revised pumps as warranty replacements.
Symptoms: Coolant temperature rise, coolant warning light, coolant loss without external leakage on very early vehicles
On early 992 models (2019–2020) the active powertrain damper mounts (PADM) were not sufficiently sealed at the factory. Water enters the mount internals and destroys the sensor.
Symptoms: PADM fault warning on the dashboard, increased vibration in the cabin, system disables dynamic mount control
9A2 engine ignition coils fail from long-term heat exposure — particularly cylinders 1 and 4 due to their proximity to the exhaust. Replace all six coils together.
Symptoms: Engine stumble, start-stop deactivated, engine control fault, misfire (OBD: P0301–P0306)
Individual injectors leave the factory faulty — documented in a Porsche TSB. Repair is carried out by replacing the affected injector individually.
Symptoms: Engine stumble under medium load, engine reduction warning, occasional power dip at full throttle
The 992 fuel tank vent valve can fail early and triggers a check engine light with an EVAP leak code. Access requires considerable disassembly effort.
Symptoms: Check engine light (CEL), fuel system micro-leak fault code, occasional clicking at low rpm
Like all DI flat-six engines without port injection, the DKCA gradually builds up deposits on the intake valves. Preventive cleaning from around 80,000–100,000 km can be worthwhile.
Symptoms: Power loss, elevated fuel consumption, occasional rough running — only noticeable at higher mileages
Vehicle Weaknesses 9
Software fault on 8,666 vehicles: the hazard lights do not activate reliably during emergency braking. Free software update at the dealer.
Early build years 2019/2020: windscreen not correctly bonded, water enters the footwell. Repaired under warranty.
The complex Targa mechanism locks up in wet or cold weather. The rear lid opens, the latches release, but the roof does not travel back. Workshop lubrication usually fixes it permanently.
The PCM 5.0 infotainment system freezes on the Porsche logo or restarts spontaneously. Driver profiles are also not correctly restored after restart. Often fixable via software.
The active engine mounts (PADM, Sport Chrono) lose their damping function due to sensor failure. In 98% of cases only the internal sensor is faulty — full mount replacement is not needed.
Door cards, dashboard area and parcel shelf creak and rattle over bumps. Several owners report build quality inadequate for the price segment.
The thermally sealed fold lines roughen up relatively quickly. Never stow a wet roof, and re-treat regularly with protectant. The issue is known from the 991 generation and has not been fully resolved.
Known noise source: the steering rack cover contacts the steering linkage and produces a creaking sound. Porsche has issued an official service bulletin for this.
Wind noise can occur around the seals at high speeds. Readjustment and silicone treatment help. Significantly quieter than the predecessor, but not at coupé level.
