We just received our ecm back from SIA, receipt says as is, no parts available. WTF Over 4 weeks and this is how we are treated? Never a phone call? No calls returned? When we did make contact they said we would receive tomorrow, no mention that they did not fix it. We have used them in the past — all good until the last time, you said nothing wrong with ecm, we spent many hours in diag time to come to the same conclusion the ecm was bad. Purchased a used one and it worked. You suck! We will contact all we can to complain!
