My 2008 GMC Acadia has 200k+...engine shaking badly, service traction control always comes on. The dealer wants to bring down the engine to check. Other shop said need to replace the engine. My last resort- tried Placentia Super Service to troubleshoot it. They were able to fix my vehicle without bringing down or replacing the engine. They were honest to tell me I dont need to buy parts. Im very pleased that i found Placentia Super Service- Friendly, honest and very knowgeable. Thank you Bob/Adrian
