My wife and I had just purchased a used 2007 GMC Yukon. Little did we know about the major issue the truck has with the reduced power reading that comes up. I really think that GMC needs to put out a recall for these issues. My wife was on her way home from a work meeting and driving on the freeway with her sister and my wife's and my daughter in the GMC Yukon and she was doing the speed limit and all of a sudden she didn't know what was going on. She called me and she was in a panic. She had to pull off the freeway and come to a complete stop and when she did the vehicle had died it turned off and she had our 2 month old daughter with out a/c and in 100 degree weather. This issue puts the people's families at risk that own these vehicles and also other drivers families at risk you can not replace a persons life if its taken away and the hardship it causes but you can replace a vehicle so why not come up with solution so the road may become a little bit of a safer place. When my wife had this happen other drivers were not courteous or understanding when someone puts their hazard lights on that something is wrong, they just kept flying past her. Now with several people having this same issue with the same gm make this issue should be resolved. I have looked up and saw chevy doesn't have this issue and chevy is the same company. If the national highway traffic safety association could create this recall and they could use the same part from chevy then surely this issue would be fixed and it would be a safer vehicle. If you were a company owner wouldn't you want to stand by your companies production and create solutions if there were these common issues? wouldn't you want to help make the road a safer place by one little fix? it wouldn't.
The cooling fan is very loud and stays on for an abnormal amount of time when the car is in park or at a stop while on only when the temperature outside is over 85 degrees. The fan will continue to stay on while driving for 10 to 15 minutes. Sometimes it won't shut off until the car is shut off and then restarted. Had it for repair on several different occasions at GMC and the technician said that is was normal.
