It is about 7500 miles on my Colorado, time for my first free oil change and I noticed a high pitch noise, that increased in pitch as rpms went up, the check engine light came on, the DEF light came on, and the screen read that I would be limited to 65mph in less than 100 miles because of "Exhaust Fluid Quality Poor."
It also had a blown out front driver's side speaker (or at least it sounds blown when there's a lot of bass).
So I took it in to the dealership to have them look at it. They found a vacuum leak around the turbo and are replacing two bolts that will be in tomorrow. (They pointed out that they paid for overnight shipping.)
The guy on the phone said the mechanic thinks that once the vacuum leak is fixed, that all the other problems will go away.
Anyone else have similar problems? All this happened after a long trip 2000+ miles with a camper trailer. I filled up with DEF about a day before these symptoms started occurring.
I will keep people updated. Maybe it will be a problem others will have as well.
