GaryK4 Posted July 19, 2013 Share Posted July 19, 2013 When I reach 50+ (more often 60+), I hear a noise coming from the engine compartment to the right side of the driver. It is hard to describe. Kind of humming almost a vibration. Is this the generator? Is this normal? So far, this is the only thing that I don't like about the car. Otherwise, I love it.

GaryK4 Posted July 20, 2013 Author Share Posted July 20, 2013 Can't any hybrid owner comment whether or not they have the same noise? Quote Link to comment Share on other sites More sharing options...
nevada rick Posted July 22, 2013 Share Posted July 22, 2013 You might try getting info from http://fordfusionhybridforum.com/ That site is infinitely more active than here. I'll bet someone there will have the answer for you. I visit that site to get general hybrid info. I am waiting to get out of my MKS lease so I can get into an MKZ hybrid. Good luck.

Steve the tech geek Posted August 27, 2013 Share Posted August 27, 2013 GaryK4, I don't notice any abnormal sounds coming from my engine compartment at those speeds. Does your car have the continuously variable transmission (CVT)? The CVT does cause, what a lot of people refer to, as a "droan" sound. This is caused by the engine, running at pretty much the same RPM, regardless of the changing MPH (acceleration) of the car. The CVT is more efficient than other common transmissions. It is one of many features that allow the MKZ Hybrid run more efficiently. So to me, the "droan" sounds like music to my ears, as I pass by those gas stations! :) Quote Link to comment Share on other sites More sharing options...
GaryK4 Posted August 27, 2013 Author Share Posted August 27, 2013 Steve, I think all 2013 Hybrids have CVT transmissions. My guess is that is not the case because the sound comes and goes. The funny thing is I go to one place once a week. On the highway I do 55-70 in both directions. It is a pretty flat road. Going there, I never remember hearing the sound. However, coming home (3) hours later, it is there again. I tried to record the sound, but my phone is not good enough. Quote Link to comment Share on other sites More sharing options...
Steve the tech geek Posted August 27, 2013 Share Posted August 27, 2013 Gary, That is odd how it does it only on the return trip - this is a shot in the dark, but it wouldn't be road noise would it? i.e. one side of the highway smoother than the other??? What about asking the dealer to take another MKZ Hybrid for a test drive so you can compare it to yours??? I know neither one of these ideas are very good. It's hard to say without hearing it first hand - but, it sure sounds like an abnormality to me. I've just never heard any sound out of mine at those speeds that would seem to be an issue at all.

John M Young Posted October 16, 2013 Share Posted October 16, 2013 I don't know, but my 2014 MKZ is the quietest car I have ever owned. I am really impressed...just no noise. kevin_sos@hotmail.com 1 Quote Link to comment Share on other sites More sharing options...

I heard this noise as we were on the road for a long trip. It was at first unsettling but I have gotten use to it. I 'think' it's the gas engine running and kicking in. But I am not sure. If you get a reply on what it is, LMK. Thanks Quote Link to comment Share on other sites More sharing options...
srcolson Posted February 7, 2014 Share Posted February 7, 2014 I heard some unusual noise. almost like letting air "squeek" out of a ballon, and found that the factory didn't properly attach the rubber seal under the hood that is nearest to the windshield. I simply "hooked" the seal back onto all of the plastic anchors and the noise went away. I still need to have a dealership handle my gurgling water in the heater core issue. I now see that this was an old problem and wonder why I'm experiencing this in a 2014. Quote Link to comment Share on other sites More sharing options...

I haven't heard about the gurgling water noise on these new models. . .is it possible that there's air in there that needs to be purged? Odd. Let us know what the dealer finds out. srcolson 1 Quote Link to comment Share on other sites More sharing options...
1984Poke Posted February 18, 2014 Share Posted February 18, 2014 I don't get that noise that you described, GaryK4. However, I do have another noise topic and would appreciate knowing what others are experiencing. In very nearly all respects, I really love my 2013 MKZ Hybrid but one thing that bothers me is when the heater blower comes on initially, as it has a lot in the last few weeks here in northern Oklahoma. The heater blower is really loud--loud enough that I wonder if there are some "doors" or vents inside the dash that aren't opening correctly. After a few minutes, when things warm up inside the car, the noise lessens considerably but during the first few minutes after the heater blower kicks in, there's quite a racket coming from the center of my dash. When I have time, I want to take it to my dealer to see if they can check it out. I got the car last summer (June) and never needed the heater in any big way until late November. Anyone else experiencing this? I may ask the same on the Fusion Hybrid forum in hopes of getting more input (if so, I'll come back here and let the folks here know). Thanks.

malcolmd Posted March 5, 2014 Share Posted March 5, 2014 I heard a gurgling noise for the first time last week, my wife says her car does it too but it's a Nissan Altima, I only heard it once and not since I have 52K miles and it's a good tight quite car.

While it won't hurt to have the Dealer check it out, what you describe sounds like normal operation. When first cold starting and once the engine has warmed up, the EATC system will run the fan/blower on high to warm up the passenger compartment/cabin as quickly as possible. Additionally, it will put airflow through the defroster vents, and I find them to usually be the loudest, since the windshield deflects the sound into the passenger compartment. Then, as the passenger compartment/cabn warms up, the fan/blower speed will decrease. Anyway, get it checked if you think there is an issue and keep us updated. Good luck.

Edslevin Posted July 31, 2014 Share Posted July 31, 2014 I just bought my MKZ Hybrid this past weekend and I notice when I first start it up there is a whurl/hum noise coming from the engine compartment. It only lasts a few minutes and then it comes back periodically during a normal drive. I called my dealer who advised that this is normal and that the noise will occur infrequently. Not sure what the source is though, whether the CVT transmission or the fan. Need further study, but in either case I would recommend that Lincoln place this known 'periodic' occurance in the owners manual so there is no consumer panic... Outside of this 'concern' I really love my MKZ Hybrid...by the way, I am a former Ford Mustang GT convertable owner and this car really surprised me in a very good way :-) Quote Link to comment Share on other sites More sharing options...

I've seen other threads where folks have discussed it. Seem most think it is a fan or blower of some kind. I only ever hear it if I am in the garage with the windows down when I start the car. I also notice it when I go to park in a quiet area with the windows down or if I get out of the car really quickly after shutting down.

Outside of this 'concern' I really love my MKZ Hybrid...by the way, I am a former Ford Mustang GT convertable owner and this car really surprised me in a very good way :-) Welcome to the forum and congrats on your new ride! :) Noises from the engine compartment can be one of four (4) things: the sound of the ICE (gas engine) running, the electric cooling fan running, the A/C compressor running (it's electric too), or the brake system boosting up in preparation for driving. And before you ask, there are a couple sounds you will hear from the rear of the car: the fuel pump, or the HVB (high voltage battery) cooling fan running. I too traded in my beloved 2005 Mustang GT convertible, that I had special ordered, on the MKZh. My back appreciates it! :) Edited July 31, 2014 by SteveB_TX Quote Link to comment Share on other sites More sharing options...

I'm 99% certain its the a/c compressor running, as it usually only makes the whurring noise at start up. My friend recently bought a Tesla Model S, and his car makes the exact same noise as mine at start up, then goes away after about 2-3 mins. He confirmed his with the Tesla dealer too. You can test this theory by turning the a/c off next time you start the car, you more than likely wont hear any sounds. I do this a lot as I like to ride with the windows down and no a/c sometimes.

bman1111 Posted October 14, 2014 Share Posted October 14, 2014 If it is like my mkz hybrid than you are probably hearing the gas engine coming one. The car is incredibly quiet except for the gas engine that cycles depending on the power demand. The engine can be a low hum or become louder depending on the state of the battery, speed and type or terrain. I find that the active noise filter does a great job except for the actual engine noise. In my research, it seems that this noise is not supposed to be cancelled out. Not sure why? Quote Link to comment Share on other sites More sharing options...

I have noticed my 2014 Hybrid seems to be making more engine noise than it did when it was brand new. With only 4000 miles I suspect I just never noticed the noise, and it isn't horrible. I kinda thought there would be lees racket with the ANC working. All things considered my current MKZ is a lot quieter than my first three Lincolns.

I kinda thought there would be lees racket with the ANC working. All things considered my current MKZ is a lot quieter than my first three Lincolns. You're correct. The ANC is for unwanted engine noises. The following pertains to the Ford Fusion Hybrid but there's no difference for the MKZ in this regard. Ford News Center: Three highly sensitive microphones are mounted in the Fusion Hybrid’s interior headliner – two over the first seating row and one over the rear – to detect and measure engine noise. These microphones send a signal to the Active Noise Cancellation control module in real time. The module instantaneously and continuously generates opposing sound waves. This reversed wave is directed through the Fusion Hybrid’s audio system, combining with the original engine noise wave to cancel out any potentially objectionable sound.

bman1111 Posted October 20, 2014 Share Posted October 20, 2014 I did some checking and if you reveiw the Lincoln video on ANC it hints that the system supresses certain noises and enhances desired sounds like the engine revving. I wish there was a clear statement on this as I would have preferred the gas engine being cancelled out. "Active noise control heightens overall cabin sound quality by reducing unwanted noises while enhancing desired sound to help provide a more pleasant driving experience." https://www.youtube.com/watch?v=6HW6PGba7xU Quote Link to comment Share on other sites More sharing options...

bman1111 Posted October 21, 2014 Share Posted October 21, 2014 The hybrid is not a high preformance system. It is based on economy. So the two motors produce approx 188 HP combined. But at high speeds the gas engine does most of the work and it is approx 145 HP. The atkinson engine is fuel efficient trading power for efficiency. If you ask it to work hard it will need to rev very high. Robert Iggy Cerami 1 Quote Link to comment Share on other sites More sharing options...
Guido Baechler Posted November 16, 2015 Share Posted November 16, 2015 (edited) I hope someone can help me with a very weird noise question. My Lincoln MkZ hybrid (2015 model year) started with a hissing, or shall I say high-pitched whistle noise at around 6000 miles (10'000 km). It is not the entertainment system or the ventilation/AC system. I can turn off all electronics in the car and the moment the car is running, the high-pitches whistle is constantly on. It sounds like an electronic noise coming from the actual hybrid battery in the back. One person said it sounds like the AC to DC converter that changes the high voltage power produced to low voltage and charges the hybrid battery in the trunk is to blame. What do you think??? Did anyone ever hear of that? I hope someone can help me with that. Guido Edited November 16, 2015 by Guido Baechler Quote Link to comment Share on other sites More sharing options...

If you ask it to work hard it will need to rev very high. It's a perfect down town cruiser. I took mine to Europe on a trip and the top speed is 172 km/h (106 mph) on the German Autobahn. Then electrical and fuel engine are at their highest "rev" point. And the battery starts smelling like a cable is on fire. It cruises nice and without being too loud to a maximum of about 145 km/h (91 mph). It's not a car made for speed. I do wish though, it would have a more powerful fuel engine, simple because this little 2.0 liter engine is quit loud. It would be nice to have some more torque/hp on the gas engine to make the ride even smoother and less "howling". Also, try to drive over the Alps, you use up all the battery within 5 minutes and then have to use the small gas engine at high revolutions. On the upside, you can recharge the battery within 10 minutes "braking down" the roads in the Alps and you will never use the gas engine until you arrive back down in the valley. That is cool and super quiet. Quote Link to comment Share on other sites More sharing options...
