I like my Sonata but to give an honest sober review I have to start off saying it is not as billed on the showroom floor.
Sticker mentioned 37 MPG city when I bought it. I live in an area that gets well over 100 degrees in the summer and bought the car in June 2011.
This meant I used the A/C quite a bit. Right out the door with the A/C on and learning the feel of driving for economy I was getting about 25 mpg in the city month or so.
I did find however that with no climate control (or only turning it on when at cruising speed) and feathered driving I could get the 37 mpg after a while.
Any AC from dead stops and that dropped to 32.
Hyundai learned of the MPG issue and issued a software change that was intended to fix it.
On a routine service I had them update the S/W and Hyundai sent me a $50 gift card for my trouble.
I thought that was a good gesture, particularly since it did nothing to delay the normal service anyway.
After the S/W update the best MPG I can get is about 32 but on the bright side, it wasn’t effected by the climate control as badly.
I recently took it in for another service and the repair order mentions another S/W adjustment and now I haven’t been able to maintain an MPG above 29…Two software updates, two declines in gas mileage.
Haven’t had it back long enough to determine all the impacts of the change.
I might ask to see if they can set it back to original factory defaults.
Additionally, I have also experienced the problem mentioned in a couple of the below posts with the lurching.
When it was new, when stopped at red lights, if the gas engine clicked on at the stop, the car would lurch in a way that on a couple occasions, I looked into my rear view to see if I was rear ended.
Also, once when accelerating to pass a vehicle on the freeway, when I pressed the accelerator, the car actually momentarily slowed rather than increase speed immediately.
Again, this was at a point when it was running on EV mode and the accelerator caused it to shift to gas engine and the transition was not smooth and responsive, and potentially dangerous as noted in below posts. That only happened once and I don’t know if one of the S/W changes addressed it but Hyundai does need to acknowledge that issue.
That all being said, it sounds like a negative review and maybe it is but, at the end of the day, I do like my Sonata. It is comfortable for me, has a reasonably smooth ride and I knew when I bought it that this was the 1st model year of the Hybrid and I expected it as such to be working out some issues.
I’m sure the 2013 and beyond will have addresses much of these issues and become more refined.
With the differences in the software I have had, I can see why these reviews are all over the map. I suppose if I were to be honest to someone looking for a Sonata, I would tell them to look at the regular gas model first as really, the title “Hybrid” in the 2011 is really just a novelty rather than a benefit and Hyundai is making good somewhat with gas cards for the mileage discrepancy.
Like the Blue package and well equipped with bells and whistles for the price. I get gas about once a month now as opposed to 2 times with my Charger RT.
Pretty much spelled out in the review.
I would however, move the emergency flasher button further from the power button.
