GMC Sierra Common Problems & Maintenance Tips

Although, the GMC Sierra is famous for its good performance and high quality, some problems will appear while using due to the long-time driving or wrong using methods; here are the most two common problems:
First one, excessive fuel consumption. In fact, it is also a usual problem with many other cars. Some GMC Sierra owners complained that they have to add oil very often and the longer they drive the GMC Sierra, the more often they have to fill oil, which is very normal. It is very likely the spark plug or fuel pump has worn out and cannot function normally. Once this situation occurs, the fuel economy will be worse.
Second, vibrations while driving. GMC Sierra drivers put forward that they can feel severe vibration with hands on steering wheel and needed more time to let the brake function and heard noise when they drive over bumps. These symptoms may be caused by a wrong shock absorber, or your drive shaft has been failed or strut mounts or other parts are broken, you need to check and replace bad parts in case worse situation happens.
If you cherish your GMC Sierra, you must to keep every part on it perfectly. Then you should take notice to some auto parts that are easy to go bad as time passes by. Seat belt or drive belt is one of them, which is very important for you and passengers' safety as well.
