reverendalc Posted June 19, 2020 Share Posted June 19, 2020 hello MKZ friends, it's been about a year of smooth sailing, but here i'm back... my 2016 mkzh is giving me some issues, and i'm at 96450 miles and chasing my CPO warranty out at 100k. it's at the dealership right now getting some work done, but they're giving me a bit of a hard time ICE occasionally makes an assortment of noticeable clunks when firing up. dealer was able to reproduce only once, but confirmed. ICE idles far more loudly than it did 50k ago, and slightly rough. ICE doesn't shutdown gracefully the dealer says they can't determine any issue regarding the ICE, despite having reproduced the issue. electric motor produces a significant grating squeal when ICE is off. this is noticeable during both acceleration, electric coasting, and regen braking. it sounds like a bad bearing of some sort the dealer says this is normal i guess that means my car was abnormal when it didn't make this noise? has anybody else been down these roads? silver lining, they're fixing my front seat climate control computer under warranty. i average 41+ mpg in my mkzh, and i want to love this car again, but it feels old and shitty now and they're telling me it's "normal" Quote Link to comment Share on other sites More sharing options...
drolds1 Posted June 19, 2020 Share Posted June 19, 2020 IDK about the ICE issues, but what's your build date? Are you sure the noise is coming from the electric motor? There's a TSB for MKZ Hybrids built on or before 8/15/15 addressing various noises coming from the CVT, including grinding. https://static.nhtsa.gov/odi/tsbs/2018/MC-10148717-9999.pdf Quote Link to comment Share on other sites More sharing options...
reverendalc Posted June 19, 2020 Author Share Posted June 19, 2020 (edited) Hi and thanks. I can’t be sure it’s the electric motor, because even if it was there I couldn’t hear it over the ICE. My build date is 10/2015 if my memory serves me correctly (it’s been at the dealer for a week now) the sound is constant and I don’t recall it changing with speed. As I come to a complete stop, it fades away in volume, but I don’t think it changes in pitch or tone depending upon speed, if that makes a difference.

reverendalc Posted June 24, 2020 Author Share Posted June 24, 2020 (edited) Following up... the dealer decided to replace one of my motor mounts under warranty as well, with regard to the occasional clunky ICE engagement. They inspected my plugs and coils and suggested it felt like a misfire, but the car has no codes stored or otherwise. they’re telling me that the noise that I’m hearing is “normal.” I took one of their techs for a short drive alongside a concrete wall so we could have the sound thrown back at us, but he insists he doesn’t hear anything abnormal. I asked that if the noise was normal, does that mean that when my car didn’t make it, then it was “abnormal?” He had no answer. I also consulted my door sticker, and to my surprise, my build date was 07/15 not 10/15 as I had previously thought (that was the first registration date). I suggested the TSB to the tech, who replied “if that was it, we’d know already” whatever that means. I brought the TSB up to the service advisor who admitted that many fords receive replacement trannies under that TSB, but there was no conclusive evidence to get ford to step up to the plate. any suggestions?
