2015 Hyundai Santa Fe Sport problems

“The vehicle suffered a severe engine overheating failure that created an immediate fire risk and electrical safety signaling failure. A brand-new replacement engine was installed by an authorized dealership in April 2026 under a goodwill warranty and had only been driven ~ 3,100 miles since installation. While operating the vehicle, the air conditioning suddenly stopped functioning. Upon restarting, the check engine light illuminated; however, there was never any dashboard temperature warning indicator, notification, or chime to alert the driver to an active overheating situation. Shortly after, the engine completely disabled itself and died while in transit in a parking lot. AAA was contacted to tow the vehicle. Smoke was visible coming out of the engine's oil dipstick and oil intake spout before being towed. After being towed home, an overwhelming chemical burning odor was noted and continued to get worse. A physical check revealed that the oil level on the dipstick was critically overfilled a full inch above the maximum fill line. The local fire department responded to the scene to mitigate the thermal risk, ordered the battery disconnected due to safety…”

“For a few months- the ABS light, Downhill assist light, and Slippery road light have all been on. Read it could be due to a bad sensor. Then on Saturday July 4th, I turned the car on and the Ebrake light was on but my ebrake was NOT initiated. Car was making a low humming noise on front passenger side of vehicle as well. I read the ebrake light could come on due to low brake fluid, so I wanted to drive it around the block to further try and diagnose the issue. My car then made a pop noise and started smoking from where the ABS pump is located and my tail lights all started flickering like Christmas lights. I instantly turned the car off and disconnected the battery to prevent an electrical fire. UPON researching- there is a recall for 2015 Santa Fe’s for this exact issue except mine isn’t on the list. I need to talk to someone who has seniority upon this situation because I have called Hyundai Customer service and my local dealership and nothing is being done or nobody cares to resolve this situation. My car is currently at a trusted local garage awaiting repair- I can not tow it back and forth between the garage and a dealership. I rely on my car for my…”

“I am writing to express my concern regarding an ongoing and persistent issue with excessive engine oil consumption in my 2015 Hyundai Santa Fe, Subject: Severe Oil Consumption Issue - 2015 Hyundai Santa Fe - VIN: [XXX] The vehicle consumes an alarming amount of oil, approximately 1 quart every 300 miles. This rate of consumption is far beyond what is considered normal and strongly suggests a serious mechanical or manufacturing defect. I have already taken the vehicle to a mechanic to diagnose and attempt to resolve this problem. Based on their professional advice, the following parts were recently replaced: 1.Engine Valve Cover Gasket 2.Turbo Charger Oil Line 3.Spark Plugs Unfortunately, despite these repairs, the issue of excessive oil consumption remains unresolved. The rate of oil loss remains consistent and dangerously high. This was first informed by a service center when I took the car for a random check. Then, after traveling 1,000 miles, the engine oil level dropped again. After that, I am keeping an eye on that. This level of oil consumption poses a significant risk to the engine's long-term health and reliability, and it is a major inconvenience and…”
