Multiple problems: 1) front right tire well hole/leak found while investigating a complaint of mold odor inside car. 2) initially, the usb and a/c were malfunctioning. Then the car radio stopped working; and now the car will not start (possible electrical shortage related to the above leak?) I tried to charge the battery; however, I believe something may be draining the battery as it keeps dying.
My 2011 GMC Terrain has a 2. 4l 4 cylinder front wheel drive. It is rated at 32 mpg highway. Since day 1 I have not even gotton close to this. I drive 100 miles a day and maybe 5 miles of it is concidered city driving. I am getting 20 to 22 mpg. I contacted GMC and they had me take it in to be checked out. The dealership hooked it up to there computer and said that everything is the way it should be. They then told GMC that it is winter now and fuel mileage will drop due to cold weather. I agree with that but not 10 miles to the gallon. Maybe 2 or 3 at the most. I cant get them to do anything about it, I am tired of having to pay out extra money for gas when this vehicle is not performing to its expectations.
I own a 2010 GMC Terrain 4 cyl. I have had several different service problems with my vehicle since June 2010. Although the service department at my dealership has been cooperative and understanding through all the service jobs performed on the vehicle, it has become disheartening and frustrating that my vehicle continues to give me problems with electrical, engine won't start up, static from radio, not able to play iphone through usb connection at times, random warning lights coming on and off on display console. I have been given several reasons of "could be" or "maybe" but never an actual concrete reason for all the numerous problems. The computer system apparently gives false readings on occassion to service department at the dealership about error codes and messages or no error messages will come up, even though there might be issues with the vehicle. My concern is with all the electronic issues, engine issue of not starting up, computer messages or lack of messages to the vehicle when there is an issue. . If I am driving the vehicle and don't know there is a problem because the computer system within the vehicle does not accurate report correct data about the status of the vehicle, then how do I know when to get the vehicle to get serviced before I am stranded with my children or worse yet, get into a car accident because of the vehicle's compter malfunction. My dealership in my hometown can only do so much with information provided by the manufacturer; so if they don't know what type of fixes to make, then my vehicle is not updated with necessary fixes when appropriate.
