Piston Slap: That Ecoboost Turbocharger Whine?

Matt writes:

Hi Sajeev,

I wrote to you a few years ago regarding a water leak in the moonroof of my old 2010 Ford Fusion. I traded that car in 3 years ago on a brand new at the time 2015 Fusion Titanium with the 2.0 Ecoboost and AWD.

I have had this car for 3 years and just rolled over 100,000KM with it. My issue is that under hard acceleration from a low speed or a stop there is a whining noise that sounds like its coming from the front of the car. The whining noise sounds like the whine a supercharger makes. If i accelerate gently there is no noise and if I floor it on the highway there isn’t a noise I can hear either.

It seems to be only a low speed thing and heavy on the throttle that recreates it.

I took the car to the dealership last week while it was under warranty and they claimed it was the turbo and replaced the turbo and a number of associated parts. The car is still making the noise under the same conditions and now my warranty is done. I’ve googled the issue and been on the Ford forums and couldn’t find anything related to the noise i’m experiencing.

Any idea why my turbocharged 2.0 Ecoboost sounds like a supercharged engine?

Capsule Review: 2014 Ford Fiesta 1.0L EcoBoost SFE

Back in June when Ford delivered a conventionally-powered 2014 Ford Fiesta to our driveway for a week-long visit, I realized that, “The subcompact buyer who wants to chase fast cars on twisty roads must move the Fiesta to the top of the list.”

With its direct and interactive steering, back-road handling chops, and surprising ride quality, the 1.6L-powered Fiesta was really rather entertaining despite its underhood shortcomings. The Fiesta easily proved why it’s used as the foundation for a genuine hot hatchback, the Fiesta ST.

Unfortunately, that which is found under the hood of the vast majority of Fiestas is a true disappointment. On paper, there’s 120 horsepower. In action, the 1.6L doesn’t want to rev. You’ll always want a lower gear, yet you’ll never find yourselves smack dab in the centre of a powerband. No subcompact should be forced to fight with such a grumpy mill.

Event Review: Ford EcoBoost Challenge

You may have noticed that Ford has been advertising its EcoBoost line of engines everywhere lately. Where I live ads for their EcoBoost Challenge event seemed to be on TV every commercial break. You’d know if you have seen one of these ads if you have heard any of the following lines:
“The Escape blew my mind. Yee Haw!”
“I love love love love it.”
“I don’t know when Ford went out and just like got awesome.”
“I felt like I was driving my mom’s car when I was in the Camry.”
“The Rav4 feels outdated. Feels like, hmm, maybe 20 years ago this could have been great.”
“Does this car also un-park itself?”
“If I had to choose between the Fusion and the Lamborghini Aventador, I’d take the Fusion.”

Ford Could Boost Displacement Of Ecoboost 3-Cylinder

The 3-cylinder Ecoboost engine developed by Ford won’t necessarily stay at its current displacement of 1.0L. According to the Blue Oval, there’s a fair bit of power – and displacement – left on the table.

Ford Bets On Ecoboost, Chrysler And GM On Natural Gas For Pickups

While both General Motors and Chrysler are putting their money on Compressed Natural Gas options for their pickup-truck lineups, Ford is going with pretty much everything but CNG as it examines alternative fuel strategies for future vehicles – and for now, the 3.5L Ecoboost V6 will be the standard bearer for light duty versions of the Ford F-Series.

  • Daniel J Our CX-5 has hit its automatic brakes a few times at in very unnecessary situations. My 2018 doesn't have it, but it will shake and throw a warning if it thinks you should brake. Only once was it needed. The dozen or so times it has gone off I was already on the brakes or traffic was in a pattern that just fooled it.

  • Daniel J For us it's just woefully underpowered. Put the 2.5T in it then I might consider it.
