This truck has roughly 41000 miles on it. As I was driving home from work on [XXX], I heard a faint noise and then my truck just lost power and died on the freeway. There were no engine warning lights on and did not want to restart and stay running. After a few times of starting and dying the message on the dash said keep driving engine is in regen. This is a diesel truck and the newer ones have a regeneration that is done with DEF. I was unable to get it off onto the exit, but did get it off the roadway. The vehicle was towed into the shop on February 3rd, 2024. The shop had to order parts and said that it was just a faulty part. I received the truck back on March 14th. I drove it home from the shop and to work for two days putting roughly 100 miles on the truck. On my way home on [XXX], the truck died again with no warning at all. Same symptoms, just no power and no warning. The truck was towed back to the shop where it still sits today. The problem is there is an issue with this thing dying without any warning at all. The dealer and Chevrolet techs have been unsuccessful in finding the problem. It has been almost 6 months in the shop with literally no idea of what is wrong. I feel this is a serious safety issue that could leave people or families stranded without any warning or idea of how to repair. I feel this should be investigated and brought to someone's attention. I have contacted Chevrolet, but unfortunately they have left everything up to the dealership. The dealer is Auburn Chevrolet in Auburn, WA.

The gas tank/gauge will be on "full", then-while driving, the gas gauge will go to "E" and the dash will alert you as to no fuel. Upon taking this vehicle to the dealer the first time, the dealer could find no issues through the computer. The "second" occurrence-the vehicle was taken to a different dealer, and they stated the fuel level sensor needed to be replaced. The "third" occurrence-the gauge went to "E", while driving, the dealer claimed it was now a cord/wire that attached to the fuel level sensor running the length of the vehicle under the truck. Since it "appears" the resolution to this issue is questionable, and the dealer(s) have not fully corrected the issue, how can I be confident the vehicle actually has fuel? also, there is an issue with the blue tooth linking to "I-phones/ios systems (only), not android phone/systems, as call/text notifications may not always alert while you are in the vehicle. The first dealer stated they contacted GM, but so far-there is no final resolution from GM regarding the blue tooth issue with I-phones/ios systems. I do have all receipts for all actions taken regarding this vehicle.
