The vehicle will shake during acceleration. It comes without warning and will cause the check engine light to flash and stay on for about a minute. It goes away on its own. However, there do not seem to be any stored codes, according to my personal OBDII scanner. The dealer refuses to take it in because there is no check engine light. However, this has happened in several occasions and could lead to an accident. The dealer appears to be waiting for the warranty period to run out.

My car is consuming major oil. I am having to put at minimum 3 to 4 quarts of oil every 3 days. I am having major loss of power. My car has oil fouled far too many spark plugs. In the last 3 months, I have had to replace the spark plugs three separate times. Within the last 3 weeks I have replaced the following: 1. Ignition Coils 2. Valve Cover Gasket 3. PCV Valve 4. 2 separate sets of spark plugs and 1 singular spark plug for Cylinder #4. My car is having a major oil consumption problem and the performance has been severely affected.

The car stalls and intersections intermittently. You have to turn the key off and turn it back on so far it has started every time.

While on an hour's drive the bsd (bling spot detection system) ceased to operate. The actuator switch was illuminated, but an error exclamation point appeared on the dash noting the bsd failure. I drove on further until I came to stop at a traffic light. This had happened a couple of months ago, also. I turned off the engine and pulled the key. I waited 30 seconds and restarted the car. They system came back online. Further along on the drive it happened again, as I was driving on a hilly road. When I went to give the car more gas, the car did not respond. I floored the accelerator, and the car still did not respond, while the bsd malfunctioned again. It was simultaneous. Additionally, the system on the dashboard that indicates where the shifter is went dark and the exact same time as the failure in both cases on this day. Of course I took the car to the dealer. They could not re-create the issue. They called Kia corporate to see if there were similar reports with a fix they might know of. The factory sent a cya response to the dealer stating that knew nothing of this issue. I had gone on the internet and found scores of similar bsd failures in both Kia and Hyundai which are sister companies. I have to believe the bsd module is made by the same manufacturer for both companies. I told the dealership if it happened again while I was in the area of the dealership I would drive the car there so they could see and possibly come up with a diagnostic code while the failure was in progress. They had no explanation for the associated loss of power...
