All 1 Known Issues
On the 2016-2019 Buick Cascada 1.6L Turbo SIDI, the German-built Buick Cascada uses the Opel 1.6L SIDI turbo (A16XHT family). Same engine family is documented for timing chain stretch on Opel Astra K and Insignia. Direct-injection design also leads to intake valve carbon buildup typically by 70,000-100,000 miles, causing misfire and rough running.

How to Fix
Chain kit replacement ~$1,500-$2,500 (parts harder to source than US-built GM engines). Walnut blast intake valves at the same service ($300-$500). Use dexos2 full-synthetic 5W-30 — required spec for European-build engines.
