NOTE: complete dealer service with oil change and all fluid levels checked 30 days prior. 2018 duramax with 20k miles. : doing a local supermarket run the other day and the limp mode light came on, engine shutdown and pulled off the highway. Tried to restart ( engine turns over nicely but won’t start). Got out and found a substantial fuel leak under the passenger side. Had vehicle towed to local Chevy dealer, awaiting diagnosis. Any ideas?
