Stoln Posted February 3, 2017 Report Share Posted February 3, 2017 I have been getting a smell of natural gas or sulfer coming from the hvac system at random times and went to dealer to deal with this, they told me it would be a diagnostic charge and may not find the problem, took it for an oil change and found the culprit. It was a PTU leaking fluid, ended up replacing the whole unit under powertrain warranty and was given rental car for free since it took longer than a day to fix. Wanted all to know this in case you have this issue. I have a 2013 Edge. 1 Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted February 3, 2017 Report Share Posted February 3, 2017 Good you caught it under warranty. Does the new unit have a drain plug? Quote Link to comment Share on other sites More sharing options...

I hope they suspected that from the beginning of you stating what you smelled since there is a bulletin on PTU failure and the customer complaining about natural gas smell in those circumstances. 1 Quote Link to comment Share on other sites More sharing options...
Stoln Posted February 4, 2017 Author Report Share Posted February 4, 2017 no they never looked for a bulletin just wanted to diagnose the issue for a fee, i told them no and oil change guy showed me ptu leak and i went back and the powertrain warranty fixed it Quote Link to comment Share on other sites More sharing options...
jmr061 Posted February 4, 2017 Report Share Posted February 4, 2017 (edited) Another lazy dealer (okay maybe that is a bit harsh)...Here is how I would expect it to go...so you smell an odor of natural gas or sulfur coming from your HVAC system. Well let me look to see if there are any known issues like that. Oh I found something that may apply. We can look at your vehicle and if the known issue exists we will see if your warranty covers it. If it has the issue and the warranty covers it then you will be fine otherwise if the warranty doesn't cover it you will be responsible for the charges. Also if that isn't the issue you will still be liable for the charges. This was found within 30 seconds of looking up 2013 Edge in OASIS using key word search of NATURAL GAS: SSM 45053 - 2007-2015 Various Vehicles Equipped With All Wheel Drive - Propane, Or Natural Gas Odor During Idle Or Low Speed Driving Some 2013-2015 MKZ vehicles equipped with a 3.7L, 2007-2014 Edge, 2007-2015 MKX, 2011-2015 Explorer, 2009-2015 Flex, 2010-2015 MKT, 2008-2015 Taurus, 2008-2009Taurus X, 2009-2015 MKS, 2007-2012 Fusion/MKZ, and 2007-2011 Milan vehicles equipped with a PTU may exhibit a propane, or natural gas odor from the HVAC systemafter driving the vehicle for 20-45 minutes. This odor, if present, is most noticeable while idling or during low speed driving. Inspect the PTU for fluid leaks and repair any leaks per Workshop Manual Section 308-07B. If odor is still present after the leak repair and cleaning, replace the PTU and vent hose, if equipped. For vehicles with no leaks and odor present, replace the PTU along with thePTU vent hose, if equipped.

Stoln Posted February 4, 2017 Author Report Share Posted February 4, 2017 Thanks, I would have though the dealer would have done some looking but yet again I had to do it for them. It is fixed and no cost to me. Quote Link to comment Share on other sites More sharing options...
