I was driving home from northern Michigan today and about an hour into the three hour trip I heard a ding and the EVIC showed a lighting bolt with a warning that said Service Electronic Throttle Control and the MIL came on as well. The Jeep seemed to lose about 50% power and struggled climbing even the shallowest grades. I stopped at an auto parts store and sprayed down the MAP with throttle body cleaner and that didn't seem to help. We limped the two (sketchy) hours home and will be calling the dealer tomorrow.

Has anyone ever experienced this before? I lost all boost, but it would shift just fine, cruise control worked, coolant temp was fine, transmission never got above 197 and it was 85+ degrees out. Thoughts? Prayers?

Yes I got this today as well. I had it a few weeks ago and they replaced the turbo sensor. The code I got today is P0299 which I think is the same code that I got a few weeks ago. No harm has been done to the jeep... I believe the turbo is shut off till after you get the code cleared. Just guessing there

I’m dealing with it right now on our 14. Fine around town but on the highway every time I’m getting a P0234 and a U1424. I’m glad I have a scan gauge so I can clear the codes while driving and get power back (until it pops back up). I replaced the MAP sensor but it didn’t help. I’m dropping it off at the dealer today. It feels like a wastegate issue as the boost doesn’t drop off quickly now.
Hopefully the aem warranty covers it.

Have you checked intercooler piping ? Maybe a hose has just dislodged. The plastic intake muffler has been known to separate as well they will both cause boost problems and throw engine codes.

Opps just read again... it is over boost problem possibly the actuator

Dropped mine off today and they are telling me it’s the egr cooler....doesn’t make sense since I have GDE and it’s not opening the egr anyways. We will see. They say it’s covered under the aem warranty, but of course they don’t know when they will have it. I’m stuck in a 2016 ram in the meantime (yes a 2016, but it’s better than no loaner).

How do you have the AEM and GDE? Is GDE back in business?

Had GDE pre AEM and got a reflash update after the AEM a month or so before they stopped selling it.

I won’t be surprised if it gets flashed over by the dealer though. Id rather have the warranty at this point since I’m at 129k and only need it to last another year or two anyway.

The service throttle means it's in torque reduction mode "limp mode" to save the engine from overheating, basically because it has some type of engine/emissions fault.

Which code does it have?

P0299 is the only code that came up. Turbo under boost. There was a loose hose clamp on the turbo outlet pipe and there was some sludge that spewed out a bit. I tightened it and disconnected the battery for a half hour. Code popped up again as soon as I started it again.

I'm under the AEM warranty so we'll see what the dealer says when I bring it in tomorrow

So I heard back from the dealer today and they said they need to replace the intake manifold as well as something with the fuel system. I'll update you guys on everything when I get it back on Friday

I got the Jeep back Friday and all seems to be back to normal. They replaced the intake manifold, fuel supply tube and turbo water feed tube. They said the code was due to all of the soot build up in the manifold. I wish GDE was still selling their hot tune that turned off the EGR
