Hi team,
I’m considering purchasing a 2022 Hyundai Santa Fe CRDi with the 8-speed DCT (Dual-Clutch Transmission), which has done close to 200,000 km. The vehicle is being sold through a damage auction tomorrow, the 23rd Oct lol 😅
I’ve test driven the vehicle twice on separate days:
First Test Drive:
The vehicle needed to be jump-started as it was hesitant to start.
After starting, I let it idle for around 5 minutes.
The drive was smooth with no noticeable issues during that session.
Second Test Drive (a couple of weeks later from the 1st test):
Again, the car required a jump-start.
I let it idle for 5–10 minutes before shifting into Drive.
This time, the transmission started in D2 instead of D1.
After moving a few feet, the car stopped responding to throttle input and would not rev up.
I shifted into Reverse, but the car didn’t move. The “R” indicator on the dashboard was blinking, and again, it hesitated to rev or engage.
Switching back to Drive, it continued to start in D2 and showed the same symptoms. No warning lights (Check Engine, Transmission, or Battery) were present on the dashboard.
To troubleshoot:
I turned the car off, got out, locked the doors, waited for about 30 seconds, and then restarted the vehicle.
This time, it started normally.
Drive engaged with D1, and Reverse also worked as expected.
I drove the car for around 20 minutes, and it operated normally with no issues.
After returning, I turned the vehicle off and restarted it multiple times, testing both Drive and Reverse, but could not replicate the earlier problem.
Question:
Could this issue be related to low battery voltage affecting the solenoids in Transmission or TCM? Or is it more likely to be a transmission (DCT) issue?
