2014 Silverado going in to service on monday for antifreeze smell in cab with heat and or on auto...Has anyone else had issues? As of last Monday there were 29 heater cores ordered by gm dealerships, (wife works at gm call center, had her look it up) no special notes from dealerships on the order.. seems like alot for a part that shouldnt have to be replaced very often..Will keep everyone updated on diagnosis from Gm dealer...

Heater core failure. Hope things have changed as on some models the entire dash has to be ripped from the truck to replace the core. Things never went back together right without rattles. Many people find it a good time to trade off the vehicle instead of deal with the problems.

 

I agree on the diagnosis but not the concern. GM interiors have been right enough for a while now to enable solid re-assembly. If it makes noise the tech did a sloppy job.

He always makes things sound worse than they are... This is a whole new truck from ground up... I'm 99.999% sure he has never replaced a heater core in a 2014. People still believe whatever was procedure was done to replace heater core in their older truck is the same... ignore it. Take it to the dealer, they will get it fixed.

Wouldnt be too smart to trade in a 2014 truck unless u like to lose alot of money. .thats what warranty is for..

well, no resolution...dealer pressure tested coolant and held pressure, no leaks, but smell of sweet syrup is still there...their solution is too drive it a few more thousand miles and hope it goes away. their theory is a new vehicle smells, from the build....what a bunch of crap...so i guess heavy car fresheners for a while then take it back for a third service faiilure and turn it in for a new one....

I have experienced this a couple times in the past few weeks. On mine the smell doesnt stay long, but its definitley there for about 30 seconds and it occures just out of the blue.

Curious to see what you find out. I have had my truck for two weeks with 850 miles and noticed the antifreeze smell in the cab. I haven't contacted the dealer yet because I thought this may be an isolated incident but have noticed after the truck gets up to temperature its doing it more frequently.

Hi I also have the same problem when the heat is on I get a weird smell (antifreeze) in the cab, bad enough to give me a headache. I sent the truck in for service at 6400km and the dealer said they took it for a test drive and smelt nothing lol. I am going back to ask if they took the time to troubleshoot basic components of the heater core. I will update once I finish.

I had this from day one on my 14. I now have driven it for a month and have used the blower quite often (Canada is cold) and it finally seems to have gone away for good this past week. I would wait a bit and see if it does go away before making a big stink about it. It went away for me.

well finally after 3rd trip to dealer, they agreed to physically check the heater core by pulling it and yes it is bad. new one on way, there were 4 in stock this morning and by 400 there had been 5 ordered by gm dealers,,,so this is becoming a common problem...wife is working with a guy at work that works on bullentins and trying to see what we can do to get one written on this problem..

      OCI, not when but why?

      By Chuck FB · Posted

      I had skimmed through that article when you posted the link and honestly I felt rather defeated in a sense and realized that all these years in changing oil that in fact putting in what I was told was a good quality oil was probably not filtered as well as it should be although the filter put on the engine would be what ( as long as it never went into bypass mode ) would be the final filtering of the new oil that the engine components would first see, but then the filtering media itself is not up to par to what is ideal because a full flow filter would be too restrictive to filter fine enough for the engines best outcome in the long run. Only one of our tractors over the years which was a Versatile with a 855 Cummins had a separate bypass filter, some engine manufacturers did spec a partial bypass system within the main oil filter but I don't believe any other trucks or equipment I was servicing used such a filter. No doubt a product like the Amsoil bypass system is of benefit as long as nothing goes sideways with the extra plumbing and filter such as a rupture/leak that could cause the oil to pump out of the engine ( yes that Versatile had a remote canister with hoses routed to it as well ). With the idiot egr system on a diesel and as a result forcing a lot more soot into the oil, that certainly isn't helping the diesel engines cause or as you pointed out the GDI engine issue with creating more soot and aside from having a fancy secondary filtering system, changing the oil more often helping lower the total soot load.     So oil manufacturing and the end product is not something one can control and I wonder if there are specs on what various oil packaging companies produce in particle count or size. As to the filtering, if the OEM is not designing a filter size and spec that is really what it could be, they too are short changing the end user and so what is the answer. Of course as you say the oil side can only do so much if the air side isn't keeping up its end of the picture and air filters are only so efficient and if in a dusty environment such as farm or construction or driving gravel roads there is a lot of dirt to filter out and some of that ends up into the air stream.    Of course the irony in places like where I am where they dump the salt on the highways but also will mix in some calcium or outright pure calcium for problem road area's, or using calcium as dust control on gravel roads, the vehicle that gets used in that environment may rust out before a properly engineered engine and maintenance finally wears out so one has to face that reality in the rust belt.

      Oil Change

      By Erfar · Posted

      have you stuck with dealer oil changes since then? I made the same switch after getting tired of crawling around under the truck, but I’ve found some dealers are way better than others about getting you in quickly. Curious if yours has been good about scheduling or if you’ve had to look elsewhere for quicker turnaround.

      Can anyone decode a VIN to determine if this truck has had emissions issues or a recall?

      By cherryred21duramax · Posted

      Thank you.   I am set on a 3.0 Duramax as my previous truck with a Ford Ecoboost had just as many, if not more, "common" issues.  Cam phasers, timing chain issues, 10-speed valve body and CDF drum, emissions issues, etc.  So I figured, why not get 2x the fuel mileage (these things got 27+mpg on every mixed city/highway test drive I put them through) and better towing capability with resale value to boot?   My minimum, shortest trip will be 50 miles 1-way and I regularly go out of state with a travel trailer.  I'm planning on using this for a marketing/event promotion business also, which would require regular towing of trailers for bands, DJs, sound and lighting gear, along with my personal camera gear for filming events.   Looked at other trucks in the $30k+ price range but the issues seem to be everywhere, plus too many with gaudy mods.  I'm literally sticking with RWD trucks because they tend to be actually used as trucks, vs. the 4x4 models I've seen with unsafe lifts, huge tires, and general mods that would affect reliability (I'm wondering if some of them were tuned, hence the aggressive throttle response and hard shifting).   So my goal is to find a stock, 3.0 with 1 or 2 owners, in good physical condition, and decently well maintained.  Can't seem to find that up here, everything in the $27-30k range has had multiple owners, smoke smell, issues, or body damage.  Or the ridiculously modified trucks with 80k miles for under $27k but lots of problems...

      That’s pretty tough Grumpy. I reread the previous few posts. They all reference oil changes. Much like your last thread. In my humble opinion it keeps things interesting.
