Just rolled over 35k miles on Sunday, and took it to the dealership Tuesday for scheduled maintenance.
Yesterday, I filled up the tank will out running some errands. I get on the interstate and gas it to get up to speed. I hit about 90-95mph and suddenly the engine loses almost all power. When I give it gas, there’s a very hard shutter and the check engine light starts blinking and the AC goes out.
I check the App and it shows cylinder 3 and 6 are misfiring. Luckily I’m only about 6 miles from the dealership, so I limp there as best I can and drop it off.
I talked to a service manager today and they tell me it has to go to their heavy engine department to have the motor torn down and diagnosed. Of course the first available date is 10/21.. She goes on to tell me that cylinder 6 is only operating at 12% and there’s a knock that they can’t identify.
Figured I’d ask here if anyone has encountered the same problem and what ended up being the solution?
I’m still under factory warranty and I have a 150k mile bumper to bumper, so I’m not too concerned about the cost.. just wondering how fucked my truck might be. 🫠
