I have a 2005 GMC Yukon Denali that I bought new in 2005. Starting in about 2009, sometimes It will not start, all of the lights/gauges/etc come on but I have to try the key 3 or 30 times before the engine
turns over. I've just been living with that problem all this time because the dealership/mechanic can't figure it out. Over the last two weeks, the battery
is dead every other day and I have to get a jump. The battery is new (only 7 months old). Computer doesn't read any error codes - battery and alternator
fine. I'm frustrated.
JA: Did you test the battery with a voltmeter? And have you ever changed one before?
Customer: That's everyone's solution. I have replaced the battery SOOOOOOO many times. And one day or one week later, same thing.
JA: Are you fixing your Yukon Denali yourself? What have you tried so far?
Customer: I've taken it to the dealership for the intermittent no start problem, but they can't duplicate or find the problem. I dropped it off with a local mechanic today to see if he can make any headway. Just thought I would look around online,,,,looks like there are a whole bunch of people with the same issue. And a million different things it could be.
JA: Anything else you want the mechanic to know before I connect you?
Customer: Nope. Thanks
