The exhaust manifold and turbocharger assembly have cracked, causing exhaust gases’including carbon monoxide’to leak into the cabin. This issue was confirmed by diagnostic testing at Burns Hyundai. The defective component is still installed on the vehicle and has been inspected upon request, costing me over $200 without any suggested reimbursement after I already told them the problem before testing. The cracked exhaust manifold allows carbon monoxide to enter the vehicles interior, posing a serious risk of carbon monoxide poisoning to both the driver and passengers. Additionally, the vehicles engine performance has been negatively affected, which could lead to unexpected failures while driving. Yes. Burns Hyundai conducted diagnostic testing and confirmed the issue, identifying cracks in both the exhaust manifold and turbocharger assembly. Despite this confirmation, Hyundai corporate has refused to cover the repair under warranty. The vehicle has been inspected and diagnosed by a Hyundai dealership service center (Burns Hyundai), and the issue has been reported to Hyundai corporate for review. No inspections have been conducted by law enforcement or insurance representatives at this time. Yes. Prior to the diagnosis, I experienced engine performance issues, including reduced power and inefficiencies, which I reported to Burlington Hyundai in 2021, when the vehicle was still under warranty. At that time, the exact cause was not properly addressed. The problem has since worsened, leading to the recent discovery of the cracked manifold. No specific dashboard warning lights were illuminated for this issue.
