same here , i have a 2020 first gen and the cost to repair these engines far excedes replacement

you are now have to start a case file with GM and hope to get some type of resolution. i have friend who also has his service brakes ligtht on after the dealership replaced his brakes and did the same thing by turning it off.

behind the rear seat passenger side

like your question, i have beenbuying used for the last 15 years just because i put almost 40k a year on. so a 5 year old truck at 200 or 230 k is the same price. you dont give up the first year big hit

i would say it is someone who bought a deisel and shouldn't have, they arenot meant to put around town or excessive idling. the brake thing is a gm problem, some do worse and some do bettter. i put 140k on my 2014 and was expecting the same on the 2020 but only got half of that mileage. a2020 with40k is not that many miles, my 2020 has 120k

it is one of those things that will only turn on with the engine running and the ecm commands it on, so it will be hard to tell

try tapping the pump lightly and see if it starts, if it doesn't then the pump needs replaced, i think it will put the engine in limp mode if you drive it

the pcv fine separator was 100 bucks, it takes 7 hours to change it.

120k on my 2.7 and run great

i have had 3 issues, the pcv fine oil separator failed at 60k, recently i had a turbo problem that was a clamp that attaches the exhaust to the turbo had come loose and turned and was stopping the actuator arm. other than that it likes to eat oil

i guess it might be depending on the type of driving. my 2.7 has 120k miles, changed the plugs at 70k and it runs as good as new. i have not used any injector cleaner

i haven't had a regular cab since 1987, just needed more space for the family VA thats a good looking truck

if it is jerking and flaring between shifts it need a valve body are even more

all depends on if you can get the service records

90-120k is when you are going to start having transmission problems, even if it has been serviced the valve body wears out and next thing you know you have burnt clutchs and the cost of a rebuild, let alone the torque converter prolems
