As I am about ready to head to CFO with the '07 with 7,300 miles, I'm wondering what the odds are for having an ignition failure. I looked at the data in the ignition failure thread to see if I could see any trends.
Here is some information:
2003: 6 failures at an average mileage for failure of 58,700 miles
2004: 3 failure, average = 25,000
2005: 1 failure reported at 22,580.
Now,
2006: 46 failures at an average of 17,800 miles
2007: 17 failures at 11,500.
What are the trends?
Plotting the number of failures that occur in 5,000 mile blocks (e.g. for model year 2006, there were 8 failures in the 5K - 10K mileage block) shows:
Here is the cumulative totals for 2006 and 2007:
Looking at this I'd have to say that the failure of 2007 models is pretty well tracking the performance of the 2006 models in the 0 - 15K miles region. I'd expect that as more 2007s get into the 15,000 - 20,000 mile range the failures will look even more like the 2006s.
I didn't do any plotting of the Gen I data. I suspect those are failures due to dirty switches rather than some systematic failure as seen in the Gen IIs. Does anybody know if there was a change in the switch design for the Gen IIs compared to Gen I?
Pretty interesting thread, Barabus, and thanks for everybody contributing to it with their stories and fixes. I'm sure carrying wire nuts, a switch, and cutters.
Cheers,
