The vehicle is subject to Safety Recall 13V‑113 (Campaign 131) for problems relating to the brake light switch. The recall repair was attempted in 2016 but the defect has recurred (current symptoms include but is not limited to: brake lights sporadically staying on with car off, key removed and all doors securely closed. This condition has caused the Battery to be repeatedly completely drained and has required a Battery replacement. Domino Effect of a Faulty Signal - Defective Switch causes intermittent, erratic, or "ghost" signals to the vehicles logic relays and computer elements. Logic Processor Confusion and Relay Chatter can mimic a relay or component failure and can lead to PCM, TCM, BCM faults, errors and vulnerability. Additionally and in the present case the ABS and Brake Warning Alert Lights have now come on as well on the Dashboard. These warning lights are not sporadic but are now apparently permanent. The dealership is refusing a second free repair, incorrectly claiming a "one-time fix" limit. Hyundai Corporate Case #42932438 was filed but ignored.

My 2011 hyundai accent has a persistent problem with ignition coil failure like other complaints found on the federal safety agency website. I have had to replace every ignition coil. The first when the vehicle was under warranty, all others after the warranty expired at cost of over $1000. Hyundai also replaced the spark plugs at the same time. My car only has 67000 miles on it, these are not components that should need replacing so early and so often. This causes financial hardship as well as a safety risk as sudden loss of power can lead to accidents and unsafe low speeds. Please issue a recall as this most of the complaints to the federal safety agency about this vehicle have to do with this ignition coil issue.

At present the car is in the hyundai dealers' shop for the same reasons as well as I was told after coils were again replace car would not start and that it is probable the crank shaft sensor now I am waiting to see when I can pick up this car which is in my opinion a safety hazard for me in addition the cost association with the repairs will be detrimental to me if I had no insurance is a retired teacher and still need transportation to get around because of arithitis and other ailments. I am truty afraid now of driving this car because it put me danger of getting hit from behind when it continues to stall on city streets and highways.

I have had to replace the coil packs on my 2011 hyundai accent 3 times so far and yesterday they went out again. My check engine light came on, car started running rough and would not accelerate properly. I went to the auto repair center and they advised that the coils were bad again and the vehicle is having a misfire. This will now be the 4th time I will have to replace all of the coil packs. I spoke with hyundai and they stated that there is not a recall for this problem and were no help on this issue.

I bought my sedan almost 2 yrs ago and I have replaced all four coils randomly since then. Yesterday my engine light came on again as I was stuck in traffic and coil 2 was misfiring again. Now that I am out of warranty I am having to argue with hyundai corporation on this matter that should be labeled a recall. Not to mention I just recently sold our 2011 hyundai accent hatchback that only had 30000 miles on it, after having it's first coil malfunction.
