general problems of the 2018 Hyundai Santa Fe

My starter failed while out shopping. No issues starting the car departing from my home, but would not start in the store parking lot. My mechanic did not provide the broken part for inspection however everyone commented that is was very unusual for it to fail as I only have roughly 25,000 miles on it. My mechanic also mentioned that this was 2nd 2018 Hyundai sante fe in the past week he had to replace the starter on that vehicle had 60,000 miles. There were no warning lights prior to the event, I suspected it was the starter after having a new battery installed and no success starting because of the lights that remained on on the instrument panel.

The contact owns a 2018 Hyundai Santa Fe sport. The contact stated that the headlights suddenly illuminated without the vehicle being turned on, causing the battery to be drained. The contact recharged the battery to start the vehicle. The contact stated that the light switch failed to turn off the high beam headlights; however, the headlights and the indicators were no longer illuminated. The vehicle was towed to the dealer, who stated that the junction block had failed and needed to be replaced; however, the contact was not sure of the cause of the failure and needed to repair the vehicle. The dealer diagnosed the vehicle that an interlock casing, fuse, and relay that had melted, and that the switches were not responding, but could not confirm what caused the failure. The contact learned that the vehicle was previously included in a recall for another junction box that had been repaired. The contact was unable to provide the recall campaign. The vehicle was not repaired. The manufacturer was informed of the failure and opened a case. The failure mileage was approximately 18,000.

The contact owns a 2018 Hyundai Santa Fe sport. The contact stated that while driving at 25 mph and approaching a stop, the vehicle stalled. The battery, check engine, and oil warning lights were illuminated. The contact stated that the failure was related to NHTSA campaign number: 22v810000 (service brakes, hydraulic). The vehicle was towed to the local dealer, where an unknown diagnosis was provided. The vehicle was not repaired. The warranty claim was denied. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 160,000.

My husband was driving our vehicle on the highway when the engine began to smoke and the caught fire. Unfortunately it was not able to be saved. We filed a claim with our carrier and are pending an inspection. We looked up our VIN and confirmed a fire recall from 2022.

The oil pressure switch has a faulty seal causing oil to leak out onto the engine block. This causes oil on the underbody and ground, smoke amd smell from oil on got surfaces, knocking noises from the engine, reduced power or hesitation, illumination or the check engine light and oil pressure light, high speed stall, and will also cause fire in the engine compartment resulting in death or sever injury. I have taken my car to the red mccombs Hyundai dealership in san antonio TX for repair and they have confirmed that it is the oil pressure switch seal that failed. The oil leak has also damaged electrical components causing a malfunction in the dash cluster and steering wheel control.

1. Abs module stopped working. Car no longer has abs. Will not cover under warranty due to computer component. 2. Engine burns oil. 3 quarts in 1k miles. Combustion cleaning done. Now engine light is one, oil light comes on, car smells of gas & oil.

In September 2024, my 2018 Hyundai Santa Fe experienced an unexpected engine lock-up while driving, creating an immediate safety hazard. Vehicle lost power, began smoking, and posed a potential fire risk. Fire department responded to prevent the engine from catching fire and had to spray the engine compartment with high-pressure water. Following this incident, vehicle remained in Hyundai’s possession for ~9 months for engine-related repairs. When we picked up the vehicle after the prolonged repair period, front-facing camera had completely stopped functioning. This camera has always worked prior to the engine lock-up and was functioning the day of the incident. This was reported to the dealership, Hyundai motor America. A case manager (nemesh) took the case. Very supportive, helpful and provided a thorough process for investigating the situation. However, all the sudden case was assigned a new case manager (bryan) and the process immediately changed and the claim was denied. Given the timing and circumstances, the camera failure appears to be the result of electrical or component damage caused during the engine failure/fire-prevention event. The dealership also confirmed that no independent inspector ever assessed the vehicle for secondary damage despite my repeated requests. Hyundai later denied responsibility without conducting any physical inspection of the damage. This sequence of events — sudden engine failure, required fire-response intervention, prolonged repair, and subsequent electrical component failure — raises significant concerns about safety and the potential for related electrical or wiring issues caused by the engine incident. I am reporting this because the underlying engine failure and fire-risk conditions represent a serious safety defect, and related component failures may indicate broader issues with damage resulting from these events. Also Hyundai not letting the independent inspector assess gives me great concern something was missed.

The day after I purchased this 2018 used Hyundai Santa Fe, the passenger air bag light came on. July 2024. I have been working with the dealership where I purchased the vehicle (larry h miller Chevrolet, in murray utah), and calling Hyundai corporation for months. Hyundai called me every 3 days for almost 3 months with a customer update and they would say is "we have no updates". This is extremely frustrating. The main idea Hyundai corporate office is telling me is that they don't have a contract with someone that would provide the vehicle part to fix this issue. They don't have a car part available in existence to fix this issue. This is a huge safety concern. I asked them "does that mean my passenger airbag could randomly go off while I'm driving down the road, or does this mean that my passenger airbag won't go off in case I got in a wreck?" they said that it could mean a number of things, but at this time, do not put anyone in the front seat of my car. The car part is a passenger airbag plate sensor that is underneath the passenger seat. Hyundai said there are no after market parts that are sufficient enough to put into the vehicle. Especially with it being a safety issue. How can this be on the consumer??? this is very crippling. This is a huge safety concern with no timeline for resolve. I am very mad. I have been fighting this for 9 months now.

In may 2024, the vehicle's oil light came on while slightly turning the wheel or braking. When taken to a dealership, they stated that the car only had one quart of oil remaining, which was 4,000 miles after my last oil change and not due for another 1,000 miles. They stated there was excessive oil consumption and recommended the vehicle be taken to Hyundai dealer. I took the vehicle to Hyundai dealer in August 2024 because the car was making a rattling sound when accelerating from 0-40mph along with the car jerking between 30-40mph if accelerating except when only applying light pressure to the accelerator. Hyundai dealer stated there was no oil remaining in the vehicle, which was why the vehicle was shaking and rattling when accelerating. They began a claim process with Hyundai as the vehicle was under 100k warranty. After two consumption tests, it was deemed the vehicle was not consuming oil as previously thought. After the last consumption test in October 2024, the oil light began to come back on with me braking the vehicle. Hyundai dealer stated there was nothing further they could do to assist and stated I'd need to reach out to Hyundai customer care to file a report. I did this 10/18/24, and in December, Hyundai customer care told me to take the vehicle back to Hyundai dealer. Hyundai said at that time that now there was an oil leak from the oil pressure sensor, which allowed oil to pass through the entire main wiring of the engine until it reached the pcm. They said I need to replace the pcm, oil pressure switch, and engine control harness for $7,000, not covered by the warranty. Parts are also on backorder for over a year. My car's oil light continues to come on, and now the engine light is coming on while my car shakes when I reach 45mph or greater. It is deemed no longer safe to drive the vehicle, especially with my children in the car. When I checked the dipstick, it was completely out of oil, which was 1500 miles after they performed oil change.

The contact owns a 2018 Hyundai Santa Fe. The contact stated that while driving at an undisclosed speed, the engine seized. In addition, when the vehicle was restarted, the rear lights were inoperable. The contact stated that only the front lights were operable. The contact stated that when the failure occurred, it was nighttime and on a busy dark road. The vehicle was taken to the dealer where it was diagnosed with failed rear toe hitch harness and the vehicle needed to be re-wired and the toe had to be removed. The vehicle was repaired. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 57,720.

Seems to be having ignition switch problems. Bought a new battery a couple times now thinking that was the problem but car won’t start at times. It won’t turn and won’t click and all the electrical (radio lights…) just seems to turn off as I turn the key with no sound following. I have to attempt 3 or 4 times with 3 minute breaks in between and then it will eventually turn and start. This has been happening about 2-3 times a week for about a year.

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.

Reverse camera malfunctioning most days. A few days a year it works, but usually it's just a blue screen. Other 3 cameras work fine all the time.

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.

Within the last few weeks my 2018 Hyundai Santa Fe sport SUV has been experiencing few noticeable issues. 1st my vehicle doesn’t want to start when I turn the key, I have to open the door close it then try again and it will turn over to start. 2nd recently driving on the highway my vehicle slowed all the way down and started jerking like it wanted to cut off. I would push my accelerator down as far as possible and it will still go slow and not speed up. 3rd my vehicle is making a throttle/knocking noise and a blinking check engine light is on as well.

Was driving and car turn off on me and wouldn't start I got it towed to Hyundai and they said my engine went out it had oil and everything we don't know why can stopped working has been sitting in my drive way for 3 years because we don't have 13000 that Hyundai told us.

The electric windows motor on the left back window was heating up it was making this unique sound every 2-4 min till I finally got tired of it and had someone find out what it was. We had to unplug the motor because it would of caught on fire while I was driving eventually.

My car engine stopped working while I was driving to work. Middle of traffic was not safe and the safety of others was effected because my car was unable to move, it was a high risk dangerous situation. Problem was reported to mechanic as well as insurance company (geico) car was pushed by strangers into a nearby parking lot, which then I waited for a towing truck. The car was inspected by a mechanic who then told me to have it inspected by Hyundai and Hyundai has told me due to lack of maintenance my car stopped working and there is nothing they can do. I am insulted by the lack of concern Hyundai has had for what they have put me and my livelihood through. I am aware of the recall on these vehicles. Engine :2. 4l i4 dgi dohc 16v. The engine light came on I had it diagnosed immediately…I was told my cam shaft and knock sensors needed replacement, they were replaced. Engine light goes off for 24 hours until it comes back on and once it came back on my car couldn’t go over a certain speed , and it died in the middle of traffic.

While sitting in park at a restaurant parking lot eating lunch, an employee noticed smoke coming from my hood area on my vehicle. Upon exiting the vehicle I noticed flames coming from the hood area, the employee attempted to use a fire extinguisher to put out the fire to no avail. Fire department arrived on scene and extinguish fire. Vehicle was towed to a Hyundai dealership for further investigation.

Recall on engine compartment , service brakes hydraulic,.

Hyundai levels 1 and level 2 made promises to do fire hazard recall plus fix other warranty issues while still under warranty. They agreed to do all at same time under warranty. Now they walk away from the fire hazard recall, reneged on other repairs and sent to Hyundai escondido which demanded payment in advance for warranty work. The car is nice but have lost confidence in vehicle due to constant reminders to dont drive often and do not park in garage. We have been in fear for over a year and they do nothing. Now they say I have to file a legal case for lemon law and pay the expenses. They promised loaner or rental plus any out of pocket but it was all a lie. They promised to find another repair dealer and again, lied. Always saying "we're having difficulty contacting the dealer" then go dark.
