I purchased this car in December 2023. As 2024 happened, I had a routine maintenance check on the car. The oil was changed, all the fluids checked etc. It appeared fine. Within a year, I have to change the spark plugs twice and once again in 2025. . That's isn't normal. The plugs were jet black. Oil is seeping out of the gas tank. Not natural. There is an oil consumption issue. My mechanic had typed notes on my receipt on what the problem(s) had been. Every other week, I am adding oil to my car. It isn't paid for. I would like a recall established on my car. I am [xxx] and need a reliable car. I went to one Hyundai dealership, provided the information my mechanic had written. Refused to give me the oil consumption test. I paid $200 or $238 for an oil change and a plug of some sort. I am aware that there was a class action lawsuit against Hyundai in 2022 for the same issue for my car. Money was paid to those whom had this issue ( I read). I have problems with my legs and back. I really need help. I need a recall on my car. Approximately, maybe a little less, every 5000 miles, my engine light comes on. I know a faulty spark plug shake. I can't afford to buy a new or replacement engine that work. I have never contacted NHTSA before I purchased this vehicle. I did call Hyundai main customer service line and was informed a recall had never been issued for this problem. Yet, numerous owners had and still have this issue along with the car hesitating at time to start. That is a problem with my as well. I am not sure of the exact date the first set of spark plugs were replaced. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
High oil consumption: to the documented tune of 40 quarts consumed april17 - December 15, 2023, encompassing 24,116 driven miles. Hyundai America and this dealer knows all about this issue and is stalling on the remedy because it requires total engine replacement. Presently I am experiencing a p1326 engine knock sensor fault and I'm told by my mechanic a prospective catalytic converter failure due to high oil consumption. Experiencing loss of power and no acceleration merging onto highway.
Engine is consuming 1 quart of oil every 1000 miles. I add 1/2 quart every 500 miles in order to be safe. If this vehicle is driven by someone other than a person like me who checks the oil level between oil changes the engine would fail due to lack of oil. The dealer wants $150 to conduct an oil consumption test! several dealers tell me that this condition is ok, really?.
