2018 Hyundai Santa Fe Engine Problems

Your engine's cam phaser components failed catastrophically, cracking the valve covers and causing a complete loss of oil. You experienced engine hesitation, unusual noise, and severe power loss just before the failure, creating a safety hazard while driving. The failure occurred without any warning lights and happened only 3,000 miles after an oil change. Repair will require replacing the cam phaser assembly, valve covers, and engine oil, along with inspection for any additional internal damage.

Your Santa Fe shut off twice while driving, and you then heard a rhythmic knocking sound that got louder during acceleration. After an oil change, the knocking slightly improved, but when you took it to a shop, they found metal shavings in the oil indicating complete engine failure—requiring a $12,000 engine replacement at just 83,000 miles. The dashboard showed no warning lights before the failure occurred. Addressing this would require full engine replacement or a complete engine overhaul.

Your engine shut off suddenly while you were driving without any warning signs beforehand. This is a serious safety concern since you lose power steering, power brakes, and engine power while on the road. A mechanic will need to diagnose why the engine stalled—this could involve checking the fuel system, ignition system, or engine sensors.

Q: What component or system failed or malfunctioned, and is it available for inspection upon request? A: Two fuel injectors on bank 2 are failing intermittently causing the engine light to flash and stay on (P0300 errors) and the car loses power. Q: How was your safety or the safety of others put at risk?

I bought my 2018 Hyundai Santa Fe 3.3L a year and a half ago with 58k miles from a dealer in Clarksville, MD. On October 18th 2022 with 70k miles my Hyundai Santa Fe starting making a loud noise in engine so I took it to a Hyundai dealer where I was told my engine would need to be replaced and was quoted 19.1k to replace it. I'm the second owner of the car so technically not under warranty.
