2011 GMC Terrain Owner Comments

problem #1

Feb 182011

Terrain 4-cyl

  • 3,000 miles


The 4 phone system developed static either bluetooth connection or using the onstar phone system. Over several months I changed phones at least 4 times. The static gets progessively worse as speed of the vehicle increase. At 70 miles per hour when a call is made from the vehicle the person on the other end can barely make out wha the person in the vehicle is saying. The vehicle has been in two separate dealerships. Vcim and microphone have been replaced twice. GM customer service tells me that it is a technology issue and they are not responsible for it. GM did work on it right up to the 36,000mile bumper to bumper. It was then their "field engineer" declared the system operated fine and there was no problem. Since then GM refuses to work on it. Their "engineer" made 1 phone call from the car for less than 4 minutes but put 86 miles on it and left it out of gas. Sitting still the system is static free. Moving it is almost useless. This is the safety aspect that bothers me is we purchased vehicle ($31,000) for bluetooth handsfree and onstar both of which are nearly useless at speed and GM refuses to do anything about it. This has been ongoing for 1.5 years. I have spent countelss hundreds of dollars on different phones and my time trying to get this issue fixed. GM customer service is useless at any speed. If they advertise "handsfree and bluetooth" it should work. Safety wise this is an issue because my wife has to resort to holding her phone while driving if she wants to be heard. I am afraid there is a more serious issue that will disable the onstar in an emergency. The public has been sold "technology" by all of the automakers. They tout it on tv but when it comes to it they won't fix it when it breaks.
