OK, mea culpa on the Tow/Haul but this time for real - Exhaust brake not working. Exhaust brake pushbutton lights but EVIC not illuminating. I used to set the exhaust brake when starting out. Do I have to be moving to get an indication? What am I missing this time? It worked last time I...

Before I got the 67A update I had two modes of Tow/Haul. Push the button once, and the indicator illuminated yellow. Push it again and it turned green. I remember reading that one of the modes was called automatic; I don't remember what the other was or what the difference was between the...

I made an appointment a few days ago and went for the recall today. Dealer took me right in and did the recall in about an hour while I waited. If anything the truck seems to run better now based only on a short drive from dealer to home. Filing a claim under the extended warranty, not so...

A few weeks ago I took the truck out and the AC wouldn't cool. After driving a few miles and perhaps turning on and off one or more times, it started working fine. Yesterday it repeated the problem except it never recovered in 30-45 minutes of driving. When turning the AC on and off I do not...

I was on the way to an appointment the other day when the truck put up the message that the DPF was 100% full and a regeneration was in progress. I have seen this a few times before, so I wasn't particularly concerned, but I had to interrupt it for the appointment. When I came out I started...

I just got this code - pending, confirmed and permanent. An old post said it could be corroded connections at the pump connector. Where is the pump and/or connector located? IS there anything else I can check? Thanks

What should I be seeing on the boost gauge for unloaded truck in full throttle acceleration? I'm getting about 3/4 scale, which would seem to be about 25 psi. Somewhere around 55 mph the boost starts reducing, I'm presuming that is the waste gate opening. Bone stock 2013 Laramie. I have...

On my latest trip it seemed the truck was running a little warmer than it should be. On a part of my drive, the water temperature gets up over 206 and, in the past, the radiator fan would come on (or speed up), the temp would cool down to 203 and the fan would shut off. This time the fan did...

Today I noticed my exhaust brake does not seem to be working. I am also concerned that the boost is low. If I hammer it while towing 9000# the boost indicator only gets to about 1 tick above half scale before the transmission shifts, RPMs and boost level drops. No MIL, but I haven't plugged...

The continuing saga of my headlight woes. The new headlight (same part number of the previous one that wouldn't adjust) won't allow the car cable connector to go in far enough to lock. I know what happens when it doesn't get locked. There is a little piece of white plastic about the size of a...

My leaky driver's side headlight let water through the connector and into the harness connector. When I changed the headlight I cleaned the corroded connections on the harness connector but functions of the headlight are failing randomly. It started with the LEDs - the parking light and turn...

I can’t unlock or lock my truck by touching the handle or pressing the lock button. The problem occurs on both front doors and with either key fob present. Either fob can lock or unlock doors. It worked normally yesterday. I have searched the fuse table in my manual and can’t find one that seems...

About to run out of my MaxCare Warranty. Are there any Jacksonville, FL (Orange Park/Fleming Island area) residents here who know a good independent repair shop? TIA Al

My 2013 is about to go out of extended warranty. I have occasionally noticed a coolant odor when the engine is hot, either from idling or pulling a load, and it is doing it now. OK, with all the cooling capacity it probably isn't hot when it has been idling but I still smell coolant. I have...

I just replaced my right headlight due to the leak that repeatedly allowed it to fill up with about a half inch of water. The harness connector had lots of algae on it so apparently water was seeping out around the headlight connector. I cleaned it up with alcohol and it all looked good. When...

I came out to the truck and unlocked it with remote. Doors and tailgate unlocked, tailgate glass did not. Started troubleshooting that and then suddenly nothing worked. I had to open drivers door with key. Dash did not light up. Checked batteries and read 5 volts. OK, something discharged...

Driving today for the first time with the windows down, I heard a whistling/squealing sound. At first I thought it was a brake pad backing plate dragging on a disc, but when I took my foot off of the accelerator pedal the sound went away. I tried a few things and discovered that the sound...

My windshield wipers work on both speeds, but the washer doesn't. I can't find a fuse listed for it. The wiper has two fuses, one for low and one for high speed. Is the pump on one of these? If so I guess I have a bad pump. Lumbar support also not working. I can't find it in the fuse list...

Yesterday I received a notice that my 8.4AN was going to receive an OTA update. Today when I got in the truck the time was wrong. I went into the menu and it was set to sync with GPS. I set the clock manually and several hours later tried to switch it back to GPS sync. The time advanced...

While driving on Friday, towing my travel trailer, I looked down and my selectable gauges (oil pressure and boost) had been replaced with a gauge that had the glow plug icon under it and a yellow bar graph that had one segment lit. There were no messages and no warnings attributable to this...
