Consumer Description
Engine is using excessive amount of oil. It has been changed on a regular basis have documentation bought the car new. I have noted that there are several complaints of the rings going bad in this model engine of the rings letting oil blow by. When is the NHTSA going to demand a recall as this can cause the motor to blow up and causes much more carbon emissions. Please make this a priority recall before more people get hurt and the emissions put out more pollutants/carbon in the air..
