2018 Hyundai Santa Fe Sport

While driving in the Highway, my car lost engine power and lead to my car run no more than 40 miles per hour, after this I took my car to the garage and the said it was the knock sensor that course this issue. After being in the garage, my car knock sensor was replace for a new one to make sure this was giving good reads and while driving in a two way street it happen again and I believe this could be very dangerous if it happen while passing another car on in a crossway. Yes. Yes. As soon it happen the check engine light started blinking. It happens 3 times end of Nov 2023, early December and late December 2023.

My car is burning oil. Took the car to the dealership where an oil consumption was complete, a chamber cleaning, and then another failed consumption test. Hyundai will only cover 60% of the engine replacement because I am the second owner. I think this is unacceptable, how do they think they’re only 60% responsible for selling cars like this? If I didn’t find this problem out when I did, I would have been stranded on the side of the road or I could have even burning my apartment complex to the ground. Someone has to do something about this, Hyundai is knowingly selling faulty cars and allowing the resell of these cars with no intention to ever cover the damages. My extended warranty will not cover anything because there is no cause of this problem. There is a class action against Hyundai over this that should be settled soon, meanwhile, these car dealerships are selling these used Hyundai/Kia timebombs. 
 Meanwhile, I’m putting a quart of oil in my car every fill up of gas, I owe 4 years on the car still, and I’m stuck. I included my email correspondence with the heartless Hyundai rep...I'm not even sure this is the right spot, I just don't want someone else to fall into this same trap as I did.

Engine died on highway. Noc sensor code indicates is a known problem for this engine. 2.4 liter Hyundai sante fe sport. Before engine died was burning much oil even after oil changes and borught in for recalls to dealer 2 mo before. Excessive burning of ooil wa a know issue at that time July 2023. Now Hyundai dealer saying the issue is a customer issue due to carbon build up on a valve. High burnin rate of oil is responsible for the carbon build up on the valve causing the engine to fail. Not a cusotmer problem but a engine design issue.

The check engine light came on. The vehicle attempts to stall when changing gears after a stop or deceleration and the engine shutters at speeds 65mph or greater. I am afraid the vehicle will stall if a fast acceleration is required such as moving onto a highway. A diagnostic was performed to confirm the engine is causing the "Check Engine Light or Service Engine Soon Light."

On January 30th 2023 we made an appointment to take our 2018 Hyundai Santa Fe Sport to our local dealership in Newmarket Ontario Canada due to a clunking in the front end of the vehicle. On inspection our 2018 Santa Fe Sport was identified as having a BROKEN COIL SPRING on the driver side. Along with this inspection it was also noted the passenger strut/shock had been leaking and was out of fluid. The Newmarket Hyundai Dealership considered this to be an emergency repair. This was determined because the coil and or both coils could totally break and puncture the front tires. This information I obtained from the Hyundai recall 167!!! Although according to the recall seemed to be only in America we truly believe our 2018 Santa Fe Sport in Canada falls into the same category of the Hyundai recall 167. It has cost us a considerable amount of money as I personally am on a Disability Government Pension as well as my wife is also on a fixed Income Retirement Pension. As for our last 3 Brand New Purchases have been nothing but Hyundai Vehicles for their reliability Safety and long lasting enjoyment!!!! That being said we are a little disappointed that this front end Coil Spring Shock/Strut issue has now made us scared of what Could have happened because of this defect that does not seem to apply at the moment in Canada. We were certainly hoping to purchase at least 1 more Hyundai SUV Product or a Hyundai vehicle with continued Reliability Safety and Always a Pleasure to Drive Product. Unfortunately this occurence has caused us a considerable amount of doubt now as we were truly scared for our lives after the issue was diagnosed by the Hyundai Dealership. My wife and I would truly like to continue to believe in the Hyundai Product of Vehicles but are now extremely concerned about Reliability and Safety at this point. According to the diagnosis there could have been a CATASTROPHIC INCIDENT!!!

This is a certified preowned vehicle. I am the second owner. I do my own maintenance. Currently this engine/vehicle has 64553 miles, I noticed it starting to use oil around the high 40k mile mark. There are no oil leaks. I have to add oil multiple times between oil changes and I just read that some of these can lock up and completely stop. I suspect this would be caused by people not checking their oil regularly however I am concerned that is the oil consumption is bad enough that this can happen at any time while driving so I wanted to add my complaint to any other existing complaints.

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.
