Three problems related to alternator/generator/regulator have been reported for the 2007 Chevrolet Suburban. The most recently reported issues are listed below.
My battery is draining. I put $300 worth of parts in it and come to find out it is an electrical issue that other people with Suburbans are having as well. It caused my brake light to stop working even with new bulbs, there is a burning smell coming from my air vents, my battery is draining while I'm driving the car, my dash lights went out for no reason and sometimes the radio doesn't want to work or the locks. I will hit u lock but sometimes I have to hit the button more then once. It does it when I'm driving. I can charge the battery and it will be good for about a day then I have to charge it again. I have had the battery tested and it is good and I have a brand new alternator and have spent a lot of money for my mechanic to do some looking around the car. That is when we found out it is an electrical issue. We just haven't pin pointed to exactly what because I dont have the money to keep looking. I called chevy and they said there's nothing they can do even tho some chevys do have a recall for wiring but mine does not.
The vehicle intermittently exhibits a dead battery. This happens regardless of whether the vehicle has been driven for hundreds of miles or none at all. At seemingly random times, we go to start the vehicle and the battery is dead. We have had the battery, alternator and cables tested. All tested good. We also notice that around the same time this problem started occurring, that engine noise could be heard through the vehicle speakers regardless of whether the stereo is on. This also occurs at intermittent intervals. We have taken to the dealership and they cannot reproduce the problem in shop in order to troubleshoot. Parasitic draw test is negative due to the fact that the problem is intermittent and not constant.
The contact owns a 2007 Chevrolet Suburban. The vehicle exhibited a no-start condition. The vehicle was taken to the dealer multiple times, in which the alternator was re-adjusted to increase the charge of the battery. However the battery continually loses energy. The vehicle was in the process of being re-inspected by the dealer. The failure mileage was 60,000. The vehicle identification number was unavailable.
