Front drivers side door lock was making a grinding noise for about a week when putting the car in reverse or drive or park. On Wednesday, February 1, 2017 it stopped working completely. It does not lock unless I manually lock it. I know there was a recall for this very reason but when I checked my VIN it doesn't come up. How can I get this repaired as part of that recall?.
Push to start does start when it's cold outside. I have to unlock the car manually since the car won't even open with the remote. I then have to struggle while in the car trying to push the start button and step on the brake. Sometimes it turns on, other times it doesn't. Its been happening since last year. And already happened twice this week.
Unintentional automatic down shift from drive to first gear when shift lever is firmly in drive position. 2011 Hyundai Sonata limited turbo 2. 0t - vehicle will automatically (on its own) shift gears from "drive" while shift lever is in the "drive" position down to 1st gear typically when driving between 5-10 mph, occasionally sometimes at slightly higher speeds. The only remedy I have found is to tap the shift lever to the left and use the shiftronic shifting to manually shift from first gear back up to drive. Have explained to two separate car dealerships who have merely dismissed it as a possible software glitch, not even allowing me to attempt to reproduce this problem, nor even attempting to test drive it to see if they can observe the unintentional unintended automatic down shift problem from "d" drive to "1st" first gear themselves.
