I wanted to provide additional information relative to recall no. 15299. This recall effected Cadillac Ats rear defrosters. The "fix" was to add software controls that minimized the risk of fire to some owner, but it certainly did not eliminate the risk. In fact I pointed out to Cadillac last year that there were still controls strategies that would could result in a fire. Meaning for some owners the recall would do nothing to minimize the risk of fire. When I expressed this to Cadillac they immediately stopped responding to my emails (attached). Since then Cadillac has quietly implemented an actual fix to the weak connectors. But they are not issuing this fix to all owners. Only to ones that complain about to lost features. Since this actual fix eliminates instead of reducing the life safety risk it must be added to the original recall.
