Don't know where you've been looking, but I've read LOTS of reports over the past couple of years of the limp mode/P1326 being resolved. The 2 most common ways it happens is either with the knock sensor wiring harness replacement, or the engine replaced. There also have been some cases of redoing the computer update, and also where replacing the knock sensor took care of the problem.Is anyone able to point me in the direction of a single thread where the problem has actually been resolved? I can't find a single thread for Hyun/Kia where anyone has said the problem has gone away.
Do you think I can request they "undo" the campaign? Everything was fine up until that point..
HOWEVER, I've never read anything like what's happened with your vehicle, where they have done everything (some twice), except replacing the engine. And there was also some stuff that didn't sound quite right to me, so it's hard to say what's going on with this stealership. I don't think they have any other choice at this point except replacing the engine, but I've said that before, and they fooled me by coming up with yet another thing to try. I'm sure you must feel like you've been put through a meat grinder a couple times by now.
I've always suspected they will eventually release an 'undo' of this upgrade, but so far at least there's been no word of that actually happening.
