| Description of the problem | 2012 hyundai sonata limited 2. 0t car looses boost when started after being left unused overnight or cold weather. 8500 miles. Apparently, the wastegate is staying open. I give it gas and the acceleration stays flat like its all engine. This usually happens when being in a ramp to enter the highway. The car acceleration goes flat and revolutions go up to 5000 to 6000. Car stays at 50-6-mph. Car went to the dealer for 5 days and gave it back because they didn't find anything. Told them about the wastegate actuator sensor but no response. When looking in the internet about this issue, there is a page http://www. Cargurus. Com/cars/discussion-t41526_ds522751 where many people are complaining about the same issue and, the problem is, that the car doesn't lit the "check engine" light so the dealer cannot scan the problem. This is a very dangerous safety issue because you might get run over by a truck when going in the highway. |
