I'm not sure about the 2013 version (because of the Euro 6 EU norm, production was stopped late 2013, I believe, and there are no 2014 versions).
Known issues with earlier (2010) versions of Punto Evo performance cars were
- Water ingress in the rear bearings, leading to multiple early failures (can be amended by installing an O-ring from Opel on the inner side of the bearing as some of their cars share the same problem and they actually found a solution)
- Front suspension, material weakness in the shock absorper springs leads to a reduction of lifetime to about 6 years or 120 000 km
- Multiair unit failure, however they changed this in 2012 already, so the problem might no longer occur with later cars
- Alternator failure
- Water ingress somewhere at the level of the rear hatch (boot)
- Loss of function of the amplifier circuit in the radio antenna socket, leading to loss of reception of FM signals
- Material weakness in the front radiator involving fissures likely triggered by high coolant pressure from max RPM runs on German autobahn (above 200 km/h, likely because of maximum liquid turnover by the water pump
- Manual gearbox fickely (1st gear sometimes difficult to put in)
- The hydraulic clutch bleeding valve might corrode and become non-functional
