Summary Verdict
The 2018 Buick Cascada presents a mixed reliability profile. The powertrain, particularly the 1.6L turbo engine and 6-speed automatic transmission, shows some susceptibility to issues like turbocharger problems and rough shifting, which can incur moderate repair costs. Electrical gremlins, especially with the infotainment system and potential battery drain, are also noted concerns. The convertible top mechanism is a significant area to monitor, as malfunctions can be costly to repair. However, the suspension and most interior and exterior components appear to be relatively robust, with no widespread critical failures reported in these areas. Prospective buyers should be aware of these potential issues and factor in the possibility of repairs, especially concerning the powertrain and convertible top.
