Coolant Issues - Under Warranty?
 
Low coolant message came on recently and there is a faint coolant smell. My '15 has just shy of 60K miles, anyone know whether potential coolant component repairs would fall under the 5yr 100K mile powertrain warranty?

Not 100%, looked for leak but so far not obvious. Smell is definitely coming from coolant tank area, maybe the tank has a hairline crack.

Any idea whether the surge tank would be covered under the powertrain warranty?

I wouldn’t replace surge tank until varifed.
Evidently you don’t have the warranty books that came with the vehicle.
People must think there weight is gold.

The Powertrain Warranty covers repairs due to defects in materials and/or workmanship for components listed below:
ENGINE
All internally lubricated parts, engine oil, cooling hoses and lines. Also included are all actuators and electrical components internal to the engine, cylinder head, block, timing gears, timing chain, timing cover, oil pump/oil pump housing, OHC carriers, valve covers, oil pan, seals, gaskets, turbocharger, supercharger and all internal lubricated parts as well as manifolds, flywheel, water pump, harmonic balancer and engine mount. Timing belts are covered until the first scheduled maintenance interval. Exclusions: Excluded from the powertrain coverage are sensors, wiring, connectors, engine radiator, coolant hoses, coolant, and heater core. Coverage on the engine cooling system begins at the inlet to the water pump and ends with the thermostat housing and/or outlet that attaches to the return hose. Also excluded is the starter motor, entire pressurized fuel system (in-tank fuel pump, pressure lines, fuel rail(s), regulator, injectors, and return line) as well as the Engine/Powertrain Control Module and/or module programming.

I had a pinhole leak (soldering issue) on my 16 that was on the bottom of the radiator under the mounting bracket. It took them a full week to find, but they fixed it 100% under warranty.

Dug out my warranty info, Rvn you are spot on. I couldn't find the leak coming from the radiator or hoses so I took it to the dealer hoping it was a warranty issue. Took them two days and they finally found it...a seal in front of the flywheel, said they have yet to see it. They'll have to pull the tranny and flywheel to get at it. I'm definitely not happy but glad it's still under warranty. My '02 never had any issues other than the the injectors. So far (on my '15), I've had my oil pan leak, def heater fail, and now this.

Anyone else have a similar seal failure?

Been on here since 2003 and never seen a coolant leak where you had to pull the tranny and flywheel to get at it.
Post the part # of the seal when fixed.

For those that don't have a paper one or would prefer the electronic one, the Warranty guides can be downloaded from GM's site.

Same booklet for gas, dmax and hybrid vehicles, but coverages are different.
If looking at the booklet, be sure to be in the correct sections. Since some stuff is same, but others depend on powertrain type, they are kinda blended together rather completely separate sections.
