2018 Silverado DTC P2138 - Stranded 3 times so far...
Replaced the accelerator pedal w/sensor the first time. Replaced the ECM the second time. Now what? Replace the throttle body and its sensors? any help?

yes, limp mode. yes, under warranty. Dealer did the above repairs. They are obviously just throwing parts at it. No real diagnosis.
Please let us know the outcome/final fix. Thanks.
Gm has a tsb on this. TSB #07-06-04-019F. Possible water intrusion into IP.
When you say stranded, do you mean it gets stuck in limp mode? Also being a 2018, isn't it still under warranty?
