My '16 Longhorn ED has 22k miles. Last Thursday it started loosing power and by the end of the day would barely make it up the hills of Austin, Tx. The check engine light came on and the electronic throttle control warning light came on. I got an email that said get it serviced asap. I took it to the dealer I bought it from the next morning, the service writer looked at the code and said it said low turbo blower pressure. They called later and said it just needed to have the ECM flashed. I guess that means software reload. This morning when I picked it up one service guy said it got a software update, that it shouldn't happen again. I don't know what to believe. Why would the ECM just go south for no apparent reason? If it happens again should I demand the ECM be replaced?
