| Description of the problem | 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. |
