New truck,weird smell??

I hope someone can help,i have only 4000 miles on my new truck and everytime I tow my 2600 pound boat there is a burning smell that I associated with the truckbeing new but hasn't went away yey..i have the v6 with the towing package from factory, any help would be greatly appreciated

 

That doesn't sound normal. I know some new cars have that burning smell from the everything breaking in, but it shouldn't only happen when towing. Have you talked to your dealership about it yet?

 

You got me, I understand the burning smell, burning off paint being new but after 4k I would think it would be gone by now.

 

Any idea where it's coming from? back, front, left, right, underneath? Pretty sure all the tow package stuff runs all the time regardless of towing or not...except maybe the trailer wiring harness burning up for some reason?

 

This is a good idea, wouldn't have thought of that. Hopefully that's not it, because that could be bad.

 

Auto or manual?

 

5 speed auto,and it seems to be stronger smell from the passenger side.and I am pretty sure it isnt the wiring

 

could it possibly be the brakes?

 

Well then my next guess would be something is rubbing or heating up in the rear suspension/tires. If you say you only smell it when towing, could make sense since the rear of the truck will sag a bit. I know 2600lbs isn't much, but it's worth checking out.

Best bet is to have your dealer look at it.

 

I guess it is possible,but I dont know why it would be. I have trailer brake!!

 

If you have an automatic this smell is not normal.
Pull over and inspect the vehicle. 4000 miles....it
has been broken in.

 

I havent talked to the dealer yet, dont want to look stupid going in there with no info! But I do have an appointment for this sat..

 

exactly what i was going to get to. possibly a misaligned brake or tire may rub when the back sags.

 

It's the new tires burning with extra weight

 

I have inspected a hundred time no leaks or signs of oil!!

 

Burning the catalytic converter maybe? Does it smell like rotten eggs?

 

The brake thing sound interesting but im sure the tire isn't rubbing

 

Nope,not eggs.

 

You also wouldnt know that the brakes are sticking cause youd think the trailer is what is just holding you back. I had a similar problem with my jeep.

 

He'd smell it all the time if this were the case, I'd think.

I wonder if the sagging of the rear end is pinching down the parking brake cable somewhere and causing it to not fully disengage, thus resulting in the smell from one side??
