What 414 owners told NHTSA about the 2018 Hyundai Santa Fe Sport

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.

I have since found out this has been a known issue and there was a class action suit in Ca. And numerous complaints to NHSTA.

On November 2nd of 2023, I was driving approximately 5 miles away from home when all of a sudden the sunroof glass shattered. It sounded like an explosion of glass. I was driving at 45 miles per hour which is the speed limit in the area. It was very alarming when the sunroof glass shattered, I was nervous and thought that someone threw a rock at the car. I wasn't sure whether to stop the car or keep on driving. Thank GOD there was no traffic, otherwise it would have been a very dangerous situation. I safely pulled over into a gas station to check what had happened. There was nothing other than broken glass on top of the car. The sunroof looks like it had pressure from the bottom up.

I have noticed for the past year that my steering column feels loose. It makes a popping noise and really makes noise on rough pavement. I feel like the steering wheel is just gonna come off into my hands. It's very loose to turn and you can feel the pops within the steering wheel. I took my car to local repair shop and they told me there was a recall and that I should take to dealer. I called dealer but my Vin # is not listed within the actual recall. However I read the recall itself and that is what is happening to my Hyundai. It makes no sense that my exact Vin # would not be included in recall since I am having that problem.

I had no warning lights or messages and then the engine threw a rod and my car just died on the side of the road. It had apparently been burning oil. I get it back after 2 months and it needs a battery. Now the check engine light is on and it has affected the catalytic converter.

We took our 2018 Santa Fe in for service because the check engine light came on and we lost power when accelerating. We were told that it has "catastrophic engine failure" and that we need a full engine replacement. On a less than 5 year old car. We are being blamed for this although we have kept up with regular oil changes and service. We were told that we could not get any warranty on the engine. We have been quoted $7,500 for an engine "replacement" and a 1 year warranty. They do not make the engine any longer so it is not even a true replacement. We brought it in to Hyundai of Metairie. They will not answer or return our calls. Do not buy a hyundai.

I have been conducting regular maintenance on my vehicle, getting oil changes, on average around every 6,000 miles. I have had the car since August 2021 and have had no accidents and haven't missed an oil change. My car is a little over 100K miles and the oil light began to come on close to 90k miles. The car is also leaking oil and all the service agent could tell me is that the are burns oil at an accelerated rate. Even though the oil light was on, NONE of the service agents mentioned any issues with the oil and nothing was mentioned when I purchased the car. I still have yet to receive the report from my last oil change from 10/06/2023. Also, the ABS light came on after I got the car serviced for a recall for the brakes and potential electrical fire while the car is parked. Each time I checked for a recall, nothing was found, even though this car clearly has an issue with oil consumption, well the engine in general.

Blind Spot Detection System failed without warning. No obvious indication it has failed. No warning lamps, messages appeared at any time. In operatioin, neither left nor right side provided warning of cars in blind spot and no audio alert was sounded when changing lanes with turn signal on and car in blind spot. (BSD failures - and any advanced safety system failure - should be readily made apparent with an alert or indication of some kind) This safety system can prevent many accidents. However, as more advanced systems are in automobiles and used, the drivers rely on them functioning properly. When they fail without indication - and the driver assumes it works, it can lead to accidents that might otherwise be avoided. If the driver is aware that the system is not working - extra vigilance, for instance, could be used. The car may be made available for inspection upon request. The problem will be reported to dealer on 10 October 2023 for analysis and repair. The car, as of this moment has not been inspected by others.

In May, my vehicle began having issues with acceleration and was choking when going uphill, or would start choking when slowing to turn or start moving after being stopped. The engine light came on and had code P1326. Dealership did a system update and it went away. The car broke down not long after, wouldn't start. Replaced battery as it wouldn't charge and was drained. Still didn't work. Towed it to dealership. After several days, they said it might be the crankshaft position sensor. A local mechanic replaced it, it did not fix it. Spark plugs were completely burnt up and covered in gas. Changed spark plugs and it seemed fixed, until it broke down last week. Has code P0420 now. Checked oil, it has absolutely no oil in it and it has only been about 3000 miles since my last oil change. It is due for an oil change, but should not be completely out of oil. Burning oil can clog cat converter, causing P0420 code. My vehicle has a theta engine, which was involved in a lawsuit and settlement, which I only learned about yesterday, and have missed the deadline to file a claim. The vehicle has lost acceleration and died while driving, posing a risk to myself and other drivers. Vehicle is unreliable and unsafe. Dealership failed to tell me anything about my spark plugs, and did not mention my vehicle having oil issues. Non-dealership mechanics have been the ones to bring the issues to my attention. Corporate Hyundai will also not help.

The 2018 Hyundai Santa Fe Sport's body coating is clearly a hazardous manufacturer defect. The paint warranty for this and other models and model years was extended to 5 years late last year, but did not provide us with any safeguard. As a warranty, correction of the defect would only be approved by Hyundai if there was an observed problem. Within weeks of the end of the vehicle's 5-year warranty period, the pearl white paint suddenly started bubbling on the front hood in June 2023. Within a month, the bubbling and peeling had extended along the entire width of the hood as the deterioration accelerated with wind impact during each drive and water impact during frequent Florida downpours. The white paint separated cleanly from the base coating, clearly indicating poor paint material and/or factory application (i.e., failure of coating layers to adequately bind). The situation had degraded to making further driving hazardous, as moving at speeds above 35 - 40 mph caused additional peeling and flaking, which caused distractive flagging of loosened patches followed by tearing of large and small pieces of paint. The former would suddenly detach and "fly" towards and past the windshield, while the latter separated from the hood in streams that resembled snowflakes. These seriously distracted the driver, and presumably nearby motorists as well, putting all at risk. Fortunately, this has not resulted in an accident. We're aware that Hyundai is responsible for this road hazard, but cannot rely on a timely recall to remedy the matter. So, at the end of July, we had the vehicle stripped to expose the metal, and reapply coatings the way they should have been at the factory. This of course was done at significant personal cost. So far, this has played out very unfavorably in terms of the public perception of the lack of accountability for this manufacturing defect by Hyundai and the NHTSA, both of whom have been keenly aware of this years-long, on-going risk to U.S. motorists.

Failed oil pressure sensor which was leaking oil through the wiring harness; could have caused a fire from oil dripping on exhaust system. Oil pressure sensors should only fail electrically, not from allowing high pressure oil to leak out. Dealer states there have been some cases where the oil flowed through the wiring harness to the vehicle ECU, rendering a severe problem in controlling the vehicle. Dealer repair invoice attached. Besides the oil pressure sensor the wiring assembly had to be replaced from the oil contamination.
