You are in the Hyundai Sonata
What is this discussion about?
Hyundai Sonata, Fuel Efficiency (MPG)
#953 of 955 2013 mpg City Driving
Oct 06, 2013 (8:28 am)
Was told by my Dealer/Service Manager that that there is a 15K mile engine break in period before true MPG can be calculated. This is a new one on me. Purchased my 2013 Sonata Sept 2012. First 2 fill-ups were 24.2 mpg. Since then I've averaged between 19 & 21 mpg. Only 6k miles on the car at this time. At this rate it will take me between 2-3 years to average the 24 mpg for city driving as advertised. Has anyone ever heard of this break-in period ?

I've owned or leased five Hyundais or Kias (shared powertrains) and I have found that FE has improved significantly as the engine gets some miles. I've seen improvement in the first 1500-2000 miles but it tends to get better beyond that, so there seems to be truth to what the dealer is telling you.
My wife's 2013 Sonata GLS, leased nearly a year ago, has almost 7000 miles on it now and it easily meets or beats its EPA FE numbers... when I drive it. My wife doesn't know how to drive for optimum FE (and yes, I've tried teaching her) so she usually gets below the EPA numbers. Which proves again "YMMV", even with the same car but different drivers.
Keep in mind however that YOU may never get the 24 mpg EPA number. It all depends on what "city driving" is for YOU and how it compares to how the EPA tests cars. No one individual is guaranteed to hit the EPA numbers. It's a means of comparing FE between cars. I don't do a lot of driving in heavy traffic, e.g. in downtowns, and rarely need to drive in stop-and-go rush hour traffic, so I know that's one reason I have no trouble beating the EPA numbers on any car I've owned or leased.

I drive the same vehicle, 2013 Hyundai Sonata 2.4, and get mileage well below the EPA estimates. Granted, I have a very short commute at very low speeds, but even on the highway, the only way I can achieve 30+ mpg is to reset the trip computer once I've reached highway speed. My combined mileage is in the 17-20 mpg range. I'm sure multiple factors contribute to the poor mileage and my driving habits could be better. That said, every other vehicle I've driven, I have gotten mileage averages in the ball park of the estimates, while this Hyundai is waaay off. My biggest problem with this is that EPA estimates are a factor when I am deciding which vehicle to purchase. Hyundai got busted with their EPA estimates on several other models and is re-imbursing owners of those vehicles, https://hyundaimpginfo.com/overview/affected-models#estimator is evidence of their over-stating economy ratings. Unfortunately, the Sonata isn't in the campaign. I'm just thankful that fuel prices have come down a little bit recently. Other than the fuel economy, I love the car.
