   I test drove the vehicle at an auction, watched several other people test drive the vehicle. Before the auction I test drove it one more time and put my obd scan tool on it to make sure there were no hidden codes or problems. I won the bid,and picked up the vehicle. I drove it approximately 6 miles from the auction and the falshing engine light popped on. I immediately pulled over in heavy freeway traffic. Put my scan tool on it and found out the knock sensor had triggered.…

   When my car is turned on there is a very noticeable shake coming from the engine area. It's not that bad once the car is driving. However, I was driving 40 miles an hour when my check engine light came on, then I was unable to accelerate and my car stalled (it's an automatic car).Once my car started up again, the check engine light was flashing, and I could only drive at like 15-20 miles per hour for my speed. Made it to O'Reilly and had them run the check engine light codes…

   I changed my oil on Saturday and it now has no oil. The engine light started flashing and my engine seized up. Now it does not run at all. It turns on halfway where the dashboard turns on but the motor/engine does not turn. It appears to be white smoke coming out of the car after trying to turn it back on.

   On 1/3/2024 the car was at a low speed - once when parking and once stopping at an intersection - when it suddenly accelerated without the accelerator being touched. The only way that the car stopped was that I was able to shift it into neutral. According to online forums, this has been a known issue with several Kia and Hyundai models.

   This is a 'Stop Lamp Switch' issue. The car will randomly turn on the ABS light causing the ABS system to engage and not allow you to use the accelerator pedal. This is very dangerous as if you are about to merge on or off a highway the car does not allow you to correctly control your speed. This issue happens more prevalently at night time when the full beam headlights (auto or manually turn on when dark out), which is very concerning. This issue has been going on for a…

9. Filed Aug 31, 2023KSBrakesLightingAcceleration & Cruise Control

   The brake lights stay on all the time, thus preventing vehicles behind mine from knowing if I'm actually stopping. Hence, they may stop without reason, and endanger drivers behind them. The manufacturer has likely known of this being an issue in Sonatas from, at least, 2007 through 2013 models. The manufacturer is putting the task of solving the problem (if that's even possible), upon a dealer. And, my trip to that (nearest) dealership (75 miles away) creates its own danger.…

    Even on a perfectly dry road, the cruise control can't be set and the traction control light comes on. The nearest dealer (75 miles away) said it was likely in need of a new brake light switch. That didn't solve the problem. Now, it is beyond the fact that the brake lights stay on whether the car is running or not. The brake light switch is clearly impacting various other functions and makes the car unsafe to drive, because vehicles following it conclude (incorrectly) that…
