Check Engine Light On Problems of Chevrolet Express

We've had 4 instances of "engine power reduced" and check engine light, with no prior warning of issue on the dash display. I believe this is due to an issue with the diesel particulate filter soot load tracking. The first 3 occurred on rural highway and the 4th on a local highway at speed. The power reduction is immediate and severe enough that the vehicle rapidly loses speed and cannot keep up with traffic. Had traffic been close or with a trailer, there would be risk of being rear ended due to the sudden loss of speed. I feel there should be some warning to give a few seconds even to put on hazards and prepare. The last two events had code: p2463, the dealer ran a service regen, but no fault was found. On the last one, the dealer gave me gm service bulletin #10-06-05-002g stating the gm would no longer cover the service regen under warranty for p2463 with no fault found. I the purchased an obd reader to monitor the dpf soot load and observed erratic behavior in the soot load, with 2 instances of the loading jumping over 100%, but apparently not enough to trip the check engine. I then contacted gm customer service to Express my concern and share the data, the dealer then ran additional tests under gm's tech guidance, but in the end gm states that they could find nothing wrong and the vehicle is operating as intended. I've attached the service records. The last record shows the dealer incorrectly listed my concern. My communications with gm customer service have all been phone calls.

I was pulling back into my driveway my van started idling very rough and erratic. The vehicle display read "engine power reduced. Service traction. Esc off. " I didn't know what to think so I immediately shut the car off. I started my car up again after letting it sit for about 10 minutes and it ran fine again but the "check engine light" was still on. The next day I was headed to work and it happened again while driving on the interstate. The same message popped up on the display and the van lost power. I had to pull over so not to be a nuisance for other drivers. After a few minutes I started the van up and I was able to make it to a nearby dealership. When I got the dealership the car was running fine of course. I left it running as I ran inside to get a tech. He came outside and seen the "check engine light" on. He brought out the scanner and said that it was something with the throttle body. My previous vehicle was also a gm product, 2001 GMC savanna 2500. I've had exactly the same problems with it. Seems like 10 years later you guys should improve these cars.
