Hyundai Santa Fe Sport fuel pump problems

Filed Mar 29, 2026 · Engine, Fuel system · CT

I bought a 2018 Hyundai Santa Fe from a dealership in May of 2023. Ever since then I have paid around $8,000 in repairs for this car. These repairs have been so expensive and time consuming that last year I wasn’t able to drive it for 6 months because it was in the shop for most of the year. I had to fix the Fuel pump, the Battery, timing chain valve TWICE, O2 sensor , Catalytic Converter, Engine valve, cylinder 1 & 3 and NOW I have to fix cylinder 2 & 4 & that cost again around $2,000 to fix. I am constantly stressed out, crying and becoming broke because I have to keep on repairing this car. I use up all of my tows every year because my car always shuts off on me while I am driving. I am at the point where I want a refund on the car and I want to get rid of this vehicle. I do not feel safe driving on the highway or driving with my two kids and I am currently pregnant again and this car isn’t safe for a family. I am constantly feeling broken down and worthless because I can’t even keep this car a float.

I was driving on March 20, 2026 at about 12:00 PM when I suddenly noticed smoke, a strong gasoline smell, an oil smell, and a burning odor coming from the vehicle. I pulled over immediately because I believed the vehicle was unsafe and at risk of fire. The vehicle had to be towed. An independent repair shop later found a fuel leak at the high-pressure fuel line / fuel pump area, a loose ground wire on the right-hand side of the engine, a valve cover gasket leak, and engine timing chain noise. I was informed that gasoline had sprayed throughout the engine bay. This created an immediate fire hazard even though no actual fire occurred. This problem was especially concerning because the vehicle had been inspected and serviced by an authorized Hyundai dealer in December 2025, less than about 3,000 miles earlier. The loose engine ground wire and fuel leak raise serious concerns about vehicle safety and the adequacy of the prior inspection. I contacted Hyundai the same day and reported this as a fire-risk safety issue, but I did not receive timely assistance. Because immediate dealer service was not available, I had to authorize emergency repairs at a local shop for safety reasons. No warning lights were noted before the incident. The failure was confirmed by the repair shop.

First ABS, I was going to fix that but all attention to me is engine light then found out it is High pressure fuel pump then burning oil that I smelled something isn't right.

I talked to the dealership mechanic shop and never tell me anything how much for high pressure fuel pump? SO I already saw my SUV problem and I decided to check website for Hyundai recalled, that what I had right now.. It's only 6 years old and only 90,000 mileages on that SUV. That smell is very odd and it will cause engine fire..
