| 10235566 | Hyundai applies a Paint Protection Film (PPF) on new vehicles before delivery to dealerships. It provides a barrier between the paint and contaminants, such as rail dust, acid rain, and industrial fallout. In rare cases, the paint can become clouded under the PPF. These spots are the result of moisture trapped between the PPF and the paint. |

This condition can be eliminated by turning on the lamps with the engine running for several minutes or during normal driving operation. |
| 10217258 | Effective June 2, 2008, Federal Motor Vehicle Safety Standard 110 (FMVSS 110) established a threshold for correcting load carrying capacity information indicated on tire placards when vehicle weight has been increased before retail sale. This limit is the lesser of 1.5% of GVWR or 100 pounds. If the total added weight exceeds the lesser of the limit, a label must be added to the driver-side B-pillar within 25mm (1 inch) of the original tire placard. |
