I purchased an ECM with the company and after putting it into the car I had multiple codes come up. I was advised by them that those were issues with the car prior to the EMC put in. I had multiple repairs done to the car and the issue was never fixed. I had a mechanic who went through all the wiring for the car and found the ECM was bad. I called multiple times before reaching a person who sent me to a voice mail. When I was able to get her back on the line she refused to give me the address to send the part back for warranty and hung up. I called again and reached a manager who also refused to give me the info and told me he will make this difficult for me. I have phone records showing all calls to try and resolve this before filing a complaint with the BBB and consumer affairs.
