Mamalou16201 Posted July 6, 2015 Report Share Posted July 6, 2015 I have 2013 hybrid sel. When I accelerate or slow to stop it whines. Sounds like an ambulance is beside car. Anyone else have this problem? Quote Link to comment Share on other sites More sharing options...
brbevil Posted July 6, 2015 Report Share Posted July 6, 2015 Unless its very loud I would say this is normal. I believe it's the regenerative braking. cheezy 1 Quote Link to comment Share on other sites More sharing options...
Redshift Posted July 21, 2015 Report Share Posted July 21, 2015 It's just the sound of the generators doing their thing. No worries. Quote Link to comment Share on other sites More sharing options...
Robert Fugate Posted July 21, 2015 Report Share Posted July 21, 2015 Did you try giving it some cheese? LOL! Honestly not sure how many miles you have on your car, do suggest a transmission fluid change. Quote Link to comment Share on other sites More sharing options...

Adrian_L Posted July 24, 2015 Report Share Posted July 24, 2015 I think we can do without the armchair mechanics. My car sounding like an ambulance would get me down to a Ford dealer PDQ. Robert Fugate 1 Quote Link to comment Share on other sites More sharing options...
Kelleytoons Posted July 24, 2015 Report Share Posted July 24, 2015 But it does beg the question as why the OP hasn't done this (it's a bit like coming on a health forum and saying, "Ya know, I haven't been able to get this bleeding stopped the last few days...") bemyax and Podivin 2 Quote Link to comment Share on other sites More sharing options...
jeromep Posted August 1, 2015 Report Share Posted August 1, 2015 I would prefer to be helpful, but... In general hybrids whine. However, that whining may be a combination of capacitor noise, hybrids are throwing around a lot of voltage and amperage as they move around, and motor/generator noise. You will hear more whining when breaking or when accelerating. When cruising there isn't much whining. Also, the whining will change depending on if the vehicle is or isn't using the ICE in conjuction with its electrics. You will always hear engine compartment sounds like whining and ICE revving, however it shouldn't be exceedingly loud. Without having a good sound track to share, it is difficult to explain how the vehicle should sound when operating properly. Quote Link to comment Share on other sites More sharing options...
OsideCMax Posted May 2, 2016 Report Share Posted May 2, 2016 My 2013 started whining about 1000 miles ago (64k total) and seems to be getting louder. Dealer should be able to diagnosis? Quote Link to comment Share on other sites More sharing options...
obob Posted May 2, 2016 Report Share Posted May 2, 2016 (edited) My 2013 started whining about 1000 miles ago (64k total) and seems to be getting louder. Dealer should be able to diagnosis? 2013s - common to have transmission problems, especially if a lot of highway driving or driving like a taxi. A design change was made late in 2013. There are messages on this site about this transmission problem. UPDATE: Sorry to mislead you about the warranty. Please report back on what the verdict is.

Dealer should be able to diagnosis?Take your car to the dealer to document the whining noise. It may be the Hybrid transmission starting to fail. The Hybrid transmission is covered under the Hybrid/Electric Unique Component warranty for 8 yrs / 100 k miles. In states that have adopted the CA emissions warranty, it's covered for 15 years / 150 k miles. Quote Link to comment Share on other sites More sharing options...
