The EGR tube may develop an engine vacuum leak causing the Check Engine (SES) light to illuminate.
The intake manifold gasket may develop external engine oil leak. The manifold gasket will need to be replaced to correct this issue. RepairPal cannot confirm a recall for this concern on these models.
