Wife drives it a week. 26 mpg. Next week 22 mpg.  Says there is something wrong. Drove it a 360 mile loop. 30 mpg. There is something wrong I tell her. Your attitude is not MPG friendly. Just drive th

Rust and boredom are my limiting factors on length of ownership. I avoid the rust by either buying new or “importing” used from southern states. Boredom I can’t avoid. Once there’s nothing left to rep

Wife bought a 2015 GMC Terrain SLE-2 AWD 2.4L. Before we sealed the deal I had Jason, my wrench, put his four man teams talents to work turning that thing inside out looking for flaws and found none.

Very interesting thread. Definitely didn’t expect to see this kind of mileage out of that engine. 

 

I'm suborn like that Ed. There's a plaque in my doctor office that says, "Don't quit, take a break." Works for allot of things. 

 

Reality is, the wife loves her SUV and even given it's issues, she'd buy another if she found one with low enough miles. Then again she has me to maintain it. :idiot:

 

Most of what ails this thing is GM shooting themselves in the foot and by extension the buyer. Besides a ridiculous breather system the cat warm up strategy, IMHO, is the dumbest thing I've ever seen an OEM do to a vehicle they warranty. On cold start it r-e-t-a-r-d-s the ignition to like -17* ATDC and dump fuel like kicking over a pail to force combustion in the CAT's for rapid warm up. This literally hoses the oil off cylinder walls and creates enough varnish precursors to stick rings in even well maintained engines. THEN if that wasn't bad enough they recommend using a wanting fluid specification at equally stupid interval. 

 

Common to all GDI motors I'm aware of is this silly practice of driving the HPFP off the cam giving a leaking pump direct and unchecked access to the crankcase. And sir, eventually they ALL leak. Your job is to "catch it if you can". Yes, these are the same people that removed dipsticks from engines and transmissions in belief Joe Average wasn't capable of checking, reading and maintain his own vehicles fluids. Sadly  and in large they were correct. Most people these days can't tell a sparkplug from a fire plug. :rolleyes: Great ideas one and all. 

 

Every move and every error calculated to defend themselves from the law and their own customers.

      Travel Trailer 2024 2500 HD 6.6 Gas Engine ?

      By Texas Gasser · Posted

      My truck is a 2024 2500 LT crew cab with the 6.6 gas engine and 10 speed trans.  It has a payload of 3578 lbs.  We pull a 22' Grand Design 17MKE that has dry weight of 5006 lbs. and a gross weight of 6395 lbs.  The trailer weighs about 5800 lbs. when loaded up with all the gear.  I don't fill the water tank for travel as most of our trips are to state parks that are within a day's drive.  Depending on the wind I get anywhere from 7.5 to 9 mpg.  I do use a weight distribution hitch (WDH) and have no problems with sway or being pulled/pushed side to side by 18-wheelers passing by me.  The trailer is about the same length of the truck so that helps a lot.  I say that because we traded in our 33' Grand Design 2670 MK (7800 lbs. loaded with gear) and using the same WDH, it would get pulled side to side by big trucks passing by me. It was not bad, but you needed to stay alert and know when a big truck was pulling up beside you.  I got about 7 to 8 mpg pulling that trailer.  I normally drive about 65 to 67 mph when pulling.  Overall, I love the payload capability of the truck as I doubt I will ever get close to its limit and I love the stability it offers over a half ton truck while pulling a trailer.  I have just over 30000 miles on the truck and have not had any issues.  We live in Texas where it is relatively flat, just windy.

      I will say though that the 5.00 a gallon for only one fuel stop while on the Number 1, that privilege of driving from the point of Paso Robles ( where I fueled up before crossing to the coast ) and all the way up ... across the Golden Gate where I stopped and walked on the bridge ( and someone jumped off the bridge opposite the side I was on ... never saw it happen but the tow truck/paramedic told me ) and continued on north back onto No 1 and all the way up to where it connects to 101 and also explored some of the Red Woods although had been through some of that before. The fantastic view of that scenic ocean route was most certainly worth the extra dollars I spent on fuel. Just prior to that I had driven through Death Valley and that was some experience in the middle of July, then spent a couple of days in Yosemite and hiked to the top of Half Dome. The summer of 2007 was very memorable for what I saw and experienced in California.

      Really depends on what extent the towing is.  Are you going across the country on highways or to fairly local campgrounds?  If you're just local towing then I wouldn't derate your truck much, just make sure the weight of your trailer and equipment stays below your limit.  Which for my truck is 14500lbs bumper pull.  Yeah it will work hard when you're over 5 figures in weight but who cares if it is just say 50 miles.    In my opinion the main thing with towing campers is wind resistance.  My 3200lb single axle camper tows fairly hard for what it is due to the wind.  But then if I use my truck to tow a family members 8000lb camper it doesn't really feel any different as wind resistance is similar. I've also towed a 5000lb airstream and it barely felt like anything was there.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      I think the excitement has run its course. Or, probably need a break from the truck for a few days.   Win some, lose some, again. There was still a coolant weep from the front of the engine. This time it was one of those worm-drive hose clamps on the upper hose connecting to the water neck. There's a reason the factory doesn't use those type of clamps; they suck. The hose is all distorted and flared at the end from someone over-tightening it. The water neck just needed to be cleaned, hose seated, and have a *good* hose clamp put on, if the hose wasn't so mangled.   Thought I'd kill two birds with one stone and try to diagnose the EGR issue. It's likely a failed EGR but before I spent $85 on the part I wanted to make sure ports weren't clogged or the pintle wasn't stuck. It was kind of a bugger to remove with the upper intake installed. Re-install (because I wanted to drive it) proved more difficult.   Per the stack of service paperwork, the EGR has already been replaced 4 times since 1996.   It would reason, then, that the EGR flange on the lower intake manifold has had its share of techs trying to work quickly and maybe one of them seated a bolt slightly cross-threaded at one time. The bolt didn't come out without significant effort and tried as I did, it wouldn't go in without significant effort. And then, the mounting ear on the right side of the EGR (lower intake casting) cracked, and crumbled off. $%&@!!!   I hate everything. Or, at least, I did in that moment. I was pretty calm, considering. This is what older, junky vehicles do. They nickel and dime their owners, piss them off, and things break that shouldn't break because of shoddy design/workmanship, poorly done repairs.   If I want to make it right, I'll need to replace the lower intake manifold and basically re-do everything I spent days doing. At least it should go quicker this time, right?! Looks like a lower intake (used/junk, of course) will run me about $150.   Once I get the new EGR, I'll see if I can bolt it up snug enough to verify proper operation, and if it solves the persistent CEL that sets on decel for EGR flow, I'll know I'm back on the right track. And then I can decide how to proceed.   Also, an idler pulley has given up. It began squeaking in pain on startup. It's clear this truck hasn't been thoroughly driven in a long, long time as things are just letting go and shaking out. I may have given it the beans once or twice to make sure my intake gaskets were doing their job. Flog an old vehicle, expect what it gives in return.

      Trailer TPS Sensor Question Rim Size

      By GMC4Zee · Posted

      Thanks for the info but wow, these are pricey! $100 apiece. A full set of smaller ones can be had for less that the cost of one of these. Gotta be a cheaper option out there but I have yet to find it. I don't want to use grommets as I can see leaking in my future. Now that I am looking at it, I might be able to just get the valve stem and modify the sensor to fit. Looks like I can just modify the hole a bit to adapt.
