There definitely a problem with the def & emission sensors on gm's duramax engines. 4th time engine unexpectedly reduces engine power while traveling at highway speeds. Results in sudden speed reduction which is extremely dangerous in almost any driving environment. These "reduced engine power" modes related to monitoring diesel emissions will get someone injured or killed (if it hasn't already)
2015 Chevrolet Silverado 2500 engine complaints
Page 2 of 2: complaints 11 to 12 of 12, newest first, as owners wrote them.
I bought this truck brand new. I started having problems about 2000 mi. The truck has a miss and jerks under load. It has been to the dealer twice and they tell me the computer doesn't show any trouble codes so there is nothing they can do. Also on occasion the ignition key is hot to the touch. Now I have to take it in again because the brake petal might fall off. What a great product...gm I think builds a lot of these problems in to save money without a care for the customer. Now I have to drive a $46,000 piece of crap thats broken. Our hands are tied and at the mercy of big business. Hope you can help. Steve
