Some of the earlier '16s had everything but the actual software in the radio. I had to take mine to the dealer about a month after i got it, and have them put it on (free). Case of radio ready, but not the software. Mark Sent from my SM-G930U using Tapatalk

Do a google search for service bulletins for your truck. I am not sure if the duallies are having the same problem, but a number of the last couple of years Dmax's have had steering problems. Look at the thread about the 2016 steering. I know yours is a 2015, but just a thought. Mark

The whole purpose of using dielectric grease is that it is non conductive. This is a simple way of protecting contacts from shorting out due to moisture in an enclosed environment. If the trailer plug on the truck didn't leak, one wouldn't have to do it. The brake test was something completely different. Mark Sent from my SM-G930U using Tapatalk

The plugs on the newer trucks seem to be a weak point. Clean and pack with the dielectric grease is a good suggestion no matter where you are located. And wholly crap, do not pull the trailer emergency brake to test it when you are hooked up to the truck. Want to talk about sending the truck into an electrical tissy...... Mark

Unless the truck senses a trailer is actually hooked up, you will not get any brake voltage at the plug. I have had some issue's and usually cleaning the plug has fixed it. Or in a rush, plugging/unplugging several times works. Mark

Just food for thought. Ford is not recommending the use of the CK-4 oil in any of its diesels. Inadequate wear protection. The bulletin is below: https://jobbersworldblog.files.wordpress.com/2016/05/ford-motor-company-ck-4-position-statement.pdf GM as far as I know, hasn't said anything. Mark

I have 18K on my '16 and so far so good. About 12K towing 9K if that makes any difference. Had the locktite SB done last summer on one of the free oil changes. If they haven't done anything by now, I doubt they will unless they are "forced". Mark

If you have the digital assist on the truck (I know all Dmax have it), that is normal. Here is the Chevy promo on it. "Tailored for Tow/Haul: A truck loaded with cargo or pulling a large, heavy trailer handles much differently than an empty truck because of the added weight. A steering wheel that normally feels light and easy to turn may require greater effort once the truck is laden. Sierra’s Digital Steering Assist solves that: When the driver pushes the Tow/Haul switch -- which also adjusts transmission tuning -- Digital Steering Assist responds by increasing low-speed assist and reducing static steering effort another 10%." Mark Edit: Believe the RPO code is NV8

They sticker it below 10K pounds due to in some states, the taxes skyrocket above that. Also DOT regs kick in at 10K for commercial ops. Which means if you use your truck for your business, and stickered below 10K, no DOT stuff. Above that with just the truck or the truck and trailer combined above 10K, DOT numbers required. All a shell game to sell more trucks. Mark

This sounds a lot like mine. And I am thinking this is the Digital steering assist, at least on mine. At highway speeds, the steering is "vague" and likes to wander around. It is not much, but it is there. I think it is the steering assist trying to "assist" you with the crosswinds and the crown of the road. Of course none of that is staying consistent, so you are correcting for the road, and what it thinks needs to be done. When I am towing (10K pounds), it is better, but that correcting the corrections drives me nuts. If there was a way to disable mine, I would. Bet a lot of the steering woes would go away. Mark

I thought it only locked the tailgate on the second press of the remote? Mark Sent from my SM-G930U using Tapatalk

I would do not use the dielectric grease on the front part of the plug, although when the contacts scrap during the connection, they should displace the grease. Due to the water intrusion I was getting, after all the connections in the rear of the plug were done, it was filled with the dielectric grease and closed up. Should not have any more water issue's, and I just make sure when I am plugging in, that it is dry and clean. Otherwise towel and/or contact cleaner, and some sand paper. As far as the stabilitrac, if it is a true failure of the system, the truck is suppose to go into the limp mode. With my "service stabilitrac" notifications, it hasn't gone into the limp mode. I sometimes think that when I get some of the notifications, the truck throws a couple more in just for fun... Mark

Yeah, welcome to the litigious world.... With America leading the charge... Some ****wad gets into an accident, which was absolutely his/her fault, but because the vehicle they were driving had some kind of safety system (which could not overcome the laws of physics and stupidity), and the person's ego could not accept that they are not Mario Andretti, they blame the vehicle and sue. Of course part of it is a money grab on top of it. Hence disable the car to avoid the lawsuit... Mark

I live in sunny SoCal, so the first time I took the truck to the dealer, they said there was water in the plug, Never figured that one out. I have seen the "service stabilitrac" one more time when I started the truck, and it went away almost immediately. Nothing since. I towed my buddies car hauler also since the last fix with no issues. Next time I will be able to get my trailer out will be in March. I would have the dealer replace the whole plug (apparently there is two parts of the plug), and make sure they cram every nook and cranny of it in dielectric grease, and keep your fingers crossed. These new trucks are extremely sensitive to any stray voltage. Remember, if the dealer computer says it is okay, then it is. Mark

I have put about 14K miles on mine, about 11K has been pulling my trailer. The DEF has been right about 1 gallon per 1K miles. I usually go about 3K miles, and fill the tank up using either the truck stop pumps, or buying the container in the truck stop store. That count down thing drives me nuts, and it is only 5-10 minutes to top it off. Mark
