2012 HYUNDAI SONATA HYBRID with 22392.0 miles

Similar to nhtsa id number: 10546231 - "check brakes" ...2012 Hyundai Sonata Hybrid will not start or move (aug 2013). From parked position, turned on vehicle (stepped on brake and depressed electronic ignition). Loud chimes occurred with message "check brakes". No brakes were on, car would not move forward/reverse. Connected to bluelink who could detect "alert". Car towed to dealer. Dealer saw code C1604 in computer log but by then car was able to start, could not duplicate problem. Dealer contacted Hyundai tech line, entered case and "repaired" by performing multi-ecv updates version #2 per tsb#13fl004; recalibrated rwolver and ec pressure. It's now 8-months later (apr 2014) and the exact same problem is occurring again. *tt

2010 HYUNDAI ELANTRA

In february of 2021, i took my Hyundai in for several recall services, including 15v100000. || in the following months, my car began to lose power steering capabilities either on ignition or while driving. Losing power steering while driving was extremely dangerous and the risk of an accident was obvious, requiring me to pull off of the road or take an exit several times. The power steering eventually failed entirely on 5/5/2021. || at this point, i ran diagnostic scan that returned the code C1604, with a definition of "ecu hardware error". || i scheduled an appointment with the same dealership that did the recall service and they determined that the issue was that the "power steering has [an] internal failure." this leads me to believe that they are referring to the electric power steering torque sensor, a key component identified in the 15v100000 recall. However, they were unwilling to cover the cost of repair ($2,990 + tax) because i had already completed the recall service. || investigating online forums (https://www.Carproblemzoo.Com/Hyundai/Elantra/2010/steering-problems.Php) showed me that there are a considerable number of people having the exact same, often life-threating, issue and are also being told by Hyundai that there is no coverage because they had the recall service completed. This is asinine as the issue only occurred for me after their recall service was completed, meaning the service either doesn't avoid or doesn't resolve the issue that lead to the 15v100000 recall in the first place. || as far as i can understand, the torque sensor was faulty as a result of Hyundai's manufacturing and the 15v100000 recall did not provide a solution to the problem. It was a false prescription and, in my opinion, the real issue would cost Hyundai too much money to fix so they are attempting pull their life-endangering vehicles off of the road by unfairly gouging their own customers.

2009 HYUNDAI ELANTRA TOURING with 47300.0 miles

There were no issues with the car until eps (red) and esc off (yellow) lights came on when the car was started one evening, and in turn the power steering was lost. Vehicle was driven earlier in the day without any problems. It was parked for about 30 minutes or so, and when it was turned on again the lights came on and the steering wheel felt like it was locked. It is very difficult to turn the steering wheel at low speeds. Vehicle was taken to a local Hyundai dealer where error codes C1260, C1604, and C1513 were diagnosed. The dealer performed the steering angle re-calibration and the ecu software update, but the errors persisted. The dealership stated that electronic power steering column and the stop lamp switch needed to be replaced. These exact two parts were a subject of two separate recalls for this vehicle (campaigns # 110 and 127) and were repaired/serviced in 2015 and the recall was closed. It is very strange that both of these parts would fail again without any notice, particularly the electronic power steering column, considering that the car only has 47000 miles and this part was repaired in 2015.
