Elk Grove Buick GMC

Our Acadia is 61/2 months old; the first oil change we were told GMC also had issued a recall that needed to be addressed; Water Pump Shaft Seal Leaks so the dealership also preformed this check. A few weeks later we realized the rattling noise was due to the panel covering the radiator was not attached. So my husband returned to the service center and that was fixed. With our mileage just shy of 14,000 miles we took the vehicle in for an oil change and tire rotation and for them to check the engine’s coolant level. We were informed checking the engine’s coolant level was not necessary; however we were due for a fuel injector cleaning. $240.00 later we now have a vehicle with an engine light on and a transmission that lurches with every shift change. How can you allow a service center to take a vehicle we absolutely love and make it seem like a lemon? My husband and I have read our vehicle manual from cover to cover and fuel injector cleaning at 15,000 miles is not mentioned! Onstar informs us the fuel injectors are not set to factory standards. You would think a dealer service center would have the ability to set the injectors at the proper standard.
