#44 of 61 2012 Sonata Check Engine Light
Feb 25, 2012 (6:00 am)
I purchased a 2012 Sonata SE w/ nav in December 2011. 4 days later check engine light came on. It has been coming on every 3-4 days ever since. Been to dealer 7 times. They replaced most of the emissions system. Light still coming on. Hyundai engineers looked at vehicle. They can't seem to find out cause. Anyone have any suggestions? I am in process of getting a refund through the NJ Lemon Law.

Spent the better part of a couple of afternoons driving cars from Ford, Mazda, Toyota, and Hyundai. I have to say that Hyundai really won me over. I was a very happy Mazda 3 owner and was expecting to get another Mazda (3, or 6) but after driving the Sonata and Genesis models, I was sold on Hyundai. I ended up getting the Hyundai Sonata (I really liked the Genesis Coupe) in the SE trim with the 2.0 turbo. I also test drove the GLS and a Limited 2.0 tubo, but after driving a Mazda 3 for 6 years, really wanted something that had better handling, tighter steering, and a firmer ride. The SE seems to give all of that. The Limited's steering felt way too numb and loose to me.
Hyundai really has a winner here.

Update: Hyundai finally repaired my vehicle. The problem was some piece of cotton in a line blocking air flow. Sounds insane but they showed me this piece of what looks like a cigarette butt. They removed it and now the car runs fine with no check engine light every 3 days.

Hmm... I'm wondering if a cigarette butt could have been sucked into the air intake? The way some people toss them carelessly out the window on the highway, I could see that being possible.
Reminds me of many years ago when my dad tossed a butt out the window. It got sucked back into the car through the open rear window, landed on my sister's lap, and started burning her. Needless to say, it was the LAST time my dad ever tossed a butt out the window!

In my case, I think it happened in the factory. I wasn't an actual cigarette butt. It was a piece of cotton that looked like a butt. Glad they found it and fixed it. I had already started proceedings with the Lemon Law.
When I was a kid the same thing happened to my dad's car. The butt burned a hole in the back seat.
Thanks for replying.

this has happenend to both my Nissans several times. The evap air lines can get clogged by moth nests and set off the codes.
#50 of 61 2011 Sonata SE & 2012 Sonata Limited
May 12, 2012 (1:12 pm)
I purchased a 11 SE in June 2011. Drove it for 10,000 miles. Really, really liked it. Bought the SE for reasons others have mentioned. Slightly more HP, sportier suspension, upgraded leather trimmed seats. 18" wheels.
I traded it in January 2012 for a 12 Limited (no navi, no turbo) because I had already blown out two wheels on potholes. In a mild winter no less. I knew it was going to be a constant issue for me in New England. Got 90% of what I paid new on the trade and got the new Limited at a very competitive $24,500.
12 Limited has been great. Though for some reason my MPG has been lower (about 26 on average vs. about 28 on SE) Doesn't make sense, but it is similar driving.
I also notice the drop in HP. Mostly around town, probably about 15-20% highway and I drive conservatively. The SE was real nice and have a better tuned engine and better MPG. If I didn't live in a bad pothole area I would have kept the SE.
No real problems on either car with a combined 16,000 miles in 11 months.

I am driving 2012 Hyundai I40 sedan, which I believe is identical to 2012 Sonata.
Please watch the LCD radio screen in the center of the dashboard. It is not visible in normal bright daytime.

I also have a 2012 Sonata GLS (American) with the preferred package. I've not had any visibility problems with the screen during normal daylight hours. I HAVE had problems connecting the Bluetooth. Dealer is replacing the head unit (I assume that means the radio guts, etc.) today, so we'll see. Other than that, I love the car -- my first brand new one in 49 years of driving.

We really love our 2012 GLS with PEP also. My old Mortorola Krzr paired with the bluetooth on the car w/o any problem. It will NOT download the contact list due to outdated software and update no longer available at Verizon due to age of phone. Next stop is an Iphone so no problem for now.
Beautiful high value car. Great road car IMO with 33 MPG 80 and 37.5 MPG at 65-70.
