I sent 1 dual stage and 1 triple stage belt in for restoration as well as a air bag module and when I installed them the air bag light didn't go off so I was of to the mechanic as they suggest in their literature. the mechanic was able to give me the codes and some pages of the manual on how to fix the problem so after I did a lot of reading I took out the triple stage belt and tested it like they should have before they returned it I found a open circuit in one of the three charges terminals so I returned it to them and they did fix it under warrenty as they should however I spent a additional 16 dollars to ship it back to them and had to pay for scanning so I could figure out what was wrong and if I understand correctly I will have to pay to scan it again to erase the code that was set when they screwed up the first time. this is on top of the 120 dollars they charged me to fix it. I could have easily gone to the ford dealer and bought a new one for less money and time.
