“I have just been having problems with this vehicle since I purchased it. When driving it sometimes feels like the truck is fishtailing, going down a straight road. The engine makes a gargling noise while driving and it gets even louder when you turn the vehicle off. The wipers work when and how they want to work; it doesn't matter what speed you put them on. I have not been happy with this vehicle at all, I looked information up on this vehicle before purchasing and it is not like the information stated.”
