NHTSA Complaint #11508637 — 2017 HYUNDAI TUCSON

Powertrain: Vehicle losses power especially going up inclines or hills. This happened before and I spent over 4500 dollars on repair of a catalytic convertor that failed. This was Late may of 2022. Now the car is back at a Hyundai dealership because the Catalytic Convertor has failed again it is Feb 2023. The car has extreme oil consumption which is one of the causes of catalytic convertor failures. The car in November of 2022 had a loss of power again but this time coils failed. Had all three coils and spark plugs replaced. The certified mechanic shop gave me the spark plugs and it was if they had a black felt on the tip of them. The mechanic said this was a sign of high oil consumption. High oil consumption is also a cause of coils and spark plugs failing prematurely. I have records to show how much oil I have bought and it is about 3 quarts every 1-2 months depending on how much I drive. This is extremely high and a sign of a faulty engine. It puts me in danger of being rear ended in traffic or on an open highway because it losses power. I use my car for work and sometimes that work takes me to small country towns. My work sometimes mean I get back when it is dark or get up when to get to work when it is dark. A car failure on a dark country road is unsafe. Yes a Hyundai dealearship in Decatur and Lubbock TX as well as a certified mechanic in Keller Texas can attest to no warning lights or codes and the car has high oil consumption. Inspected by two different hyundai dealarship service repair locations NO warning lights, no check engine lights, nothing to give notice of a problem about to occur. I have tried to deal with Hyundai but they refuse to accept that the issues are due to a bad manufactured engine. However all the signs point to that is the problem. Lastly the check brake light comes on but mechanics can never find a problem. So they replace the bulb but it just keeps happening. It will come on , stay on for a day , then go off. Just periodic
