Emission system, 65 mph max speed is on screen. We don't

Customer Question

Hi emission system, 65 mph max speed is on screen. We don't have time to be checked. On road now and our lively hood depends on this truck right now. we sell Christmas trees and on way to get load now. We will basically not survive financially of we don't make this trip. So going to keep driving regardless. Is that ok
JA: What is the model of your '65 Chevy?
Customer: 2015 duramax dually
JA: Are you fixing your vehicle yourself? What have you tried so far?
Customer: Tightened gas cap and stuff under hood. We can not afford to miss this. Christmas treed are already ordered. This is a 20 hr round trip and we are halfway to destination. So will be driving truck for another 900 miles with this message. Do you think speed will really be reduced. Our financial survival depends on this trip and we have no other options.
JA: Has the vehicle turned into a gas hog? And how does it start -- same as usual?
Customer: Not sucking up anymore fuel than normal. Starts just fine
JA: Anything else you want the mechanic to know before I connect you?
Customer: Everything seems to be running fine. Just the emmisions system.message saying 65mph max speed in 108 miles

This message is indicating that the emissions redux system is about to go into a power reduction mode to burn the soot and carbon out of the particulate filters in the exhaust system. These systems have been a little finicky on the newer duramax trucks. How many miles do you have on your truck? How much DEF do you have in your DEF tank?
