2014 SILVERADO Fuel/oil leaks

[BigPop]

Just bought a new '14 Z71 LTZ 4x4 5.3 Saturday. Fuel smell Sunday, back at the dealer Monday. Heard there have been perhaps issues with o rings on injectors leaking? Also noticed stain on garage floor near the rear axle. Looked underneath, and the ENTIRE underside of the bed has a coating of some type of oil. Beyond livid. Just got rid of a Ford F150 that stayed in the dealer's shop. A brand new $50K truck with less than 50 miles, now in the shop since Monday?? Not a happy camper. Also, dealer showed milage at 11, when in fact it was 140 and someone had the My Link with their iPhone name in it. Any ideas on the fuel smell or oil coating?

Sounds like the dealer gifted you somebody else's problem - that truck has been returned once before, looks like.

 

Hard to believe 7 years (almost 8 now) has gone by since I bought my truck new. First new vehicle purchase ever ......... and the LAST.

Wipe your finger on the oil under the truck and smell it. Gear oil has a strong sulphur smell to it. Where did the dealer write the mileage as being 11? There is something confusing about your post as well, dealer says mileage was 11, you say it was actually 140, and the truck is in the shop with less than 50 miles on it.

 

The title of the vehicle should show you past owners. If you are the only one, then I would think that someone test drove that truck, and tested the iPhone connectivity. The key here is the title.

 

Today is Friday, you dropped the truck off on Monday and still do not have it back? They must have given you a loaner to drive. Not sure I would want the truck back if it has spent the first week of ownership in the repair shop for something that should be simple to fix.

Where are the GM Customer Service Reps? This is the kind of problem they should be jumping right on top of. Brand new truck. New Gm customer came over from Ford. And dissatisfied already. Not very good customer relations so far. I know its Friday but its not quitting time yet.

GM has been asleep at the wheel for a long time now ....

Update. After some prodding, the dealer did provide a loaner. Picked up the truck yesterday. Pressure tested the fuel system, no leaks. I was concerned due to some other posts I have read with issues regarding injector o rings not seated properly. Suspicion by dealer is the leak in the rear end was a "gouge" around the seal where the drive shaft mates with the rear axle. Replaced the part and seal. Pressure sprayed the underside of the truck to remove the oil that was flung all under the truck and bed. "Gas" smell was explained as the petroleum based lubricant that was flung all under the truck. Still cannot explain where the 140 miles came from or who "*****" was who was loaded into my My Link system. Possible explanations were a "dealer trade." Apparently an estimate was made on the odometer statement at time of sale for 11 miles, truck actually had 140. I have to say, the dealer treated me OK with the issue. Wish it did not take five full days to fix it. But they said a big part of Monday in the shop was PDR on two dents that were down low perhaps during the build or in transit. GM did apologize to the mechanical issues. And said he hoped I would now be able to enjoy the truck as I should have when I took delivery. Seemed sincere. Just overly frustrated thinking I may have just bought a $50,0000 headache. So far, no more leaks. I will have to say, the "goodies" on this truck far exceeded the Ford. Took a couple of Xanax and came down from the sphincter sphere.

Just FYI ... if you live in the rust belt, and plan on owning the truck longer than 7 years or so, I'd have left the oil on the undercarriage.

 

Every winter I hose mine down WITH motor oil to protect it against road salt. It's messy ... but it WORKS.

Happy to hear things are going better, good luck with your new truck.

I have a 2014 Sierra and while in the mountains today I had a puff of steam smoke from the front grill passenger side . there seems to be some oil on the grill and bumper but not where else and all fluids are full it's almost like it burped lol I was climbing up a mountain road to go snowboarding anyone else have that issue is it maybe the oil cooler line ?no oil is leaking at all and it's dry under the truck just the oil that I cleaned up and now nothing?????I'm do for my transfer case recall so I'd like any help before intake it in

[elviswas]

where does the engine oil cooler line join in the rad can't see where it is can u access

[Doug_Scott]

First thing to check is what type of fluid leaked out. From your description it sounds more like coolant that oil. Quick easy check is to touch the fluid with a finger, and taste it. If it is sweet tasting it is coolant. The rad cap will vent at about 15psi. Once that happens, the fluid coming out will boil immediately due to no more pressure.

well govtech4 hard to take in when it's done it once and not a drop of oil anywhere now that's it's cleaned off the grill by the snow

just seeing if anyone else has had that happen to them

The only way it can get on the outside of the grille(the part that snow can remove it from) is to come from behind the grille. Find any remnants of it, and see what the fluid actually is. If there is absolutely no trace of the fluid, then that is what the technician will say as well. Can find something that is not there.

 

It will not be from oil cooler lines or the cooler its self simply because once it starts to leak, it will continue to leak, plus, water(melted snow) will not remove oil from anything without leaving a layer of oil.
