was wondering if anyone know about this. I have a 2007 STS4 ISG I believe it is, as it has every option. Plus it's mountain laurel pearl pink.
(former Mary Key car). Bought it for the G/F. When going over bumps, the rear end bottoms out. the front still feels fine. There are no codes and nothing comes up on the DIC, and I can see no leaks. Feels like the shocks don't work. could both have gone bad at once? Do they do that when they go bad? It doesn't even restrict me to 80MPH. I have 143.760 KM -89328.3 miles on it. And of course the warranty went out 2 months ago lol. Anyone have ideas? help would be much appreciated.
