Hyundai Genesis fuel pump problems

Filed Apr 30, 2026 · Seat belts · MD

I have a 2015 Hyundai Genesis. I had an over heating issue with the car in January of 2025. Took the car to an authorized dealership, and had the repair made.a month later a code appeared on my Dash it read “PSB “. I went to have my vehicles emission’s test and the car failed. I took the car to an authorized Hyundai dealer and they said its most likely the fuel pump module, but wouldn’t know til they examined it thoroughly. After they replaced the fuel pump p module they called me and said that the seat belt positioned went bad and it was explosive. That it’s a safety feature on this model and it was caused by the fuel pump module. If the dealt belt is a safety feature and it becomes defective, shouldn’t it be under warranty? You can’t drive in my state I belted, and if the seat belt positioner is explosive isn’t that a hazard? I think the seat belt , any part of the seat belt should be a warranty item for the life of the car, especially if it’s for safety. I am now being told that there is a $1500 cost in order to fix this item.

My 2016 Hyundai Genesis started flashing a code stating “Check PSB” only a week after buying the car. PSB means Pre-active Seat Belt. The seat belts somehow interlink with the fuel pump. My car has a faulty fuel pump module, causing the PSB warning to flash, even when the vehicle is in motion. It also causes a loud humming coming from the rear of my car, as I accelerate. I’ve done research, and it says MANY owners of the same vehicle report the faulty fuel pump module as the culprit, causing the Check PSB. As well as many owners online stating their vehicle has done the same as mine. There is active recalls on the newer years for this issue, such as the 2023. When the same issue is reported multiple times on the 2016s too, there should be a recall. This is a common issue, & quite frankly a dangerous one. If the fuel pump module is miscommunicating with the seat belts, that could cause them to not react in a collision. I have my vehicle scheduled to be serviced in a few days.

Car experience loss of control to accelerator while driving on major highway. The vehicle's speed coasted down from highway speed of 65mph to low 50s before vehicle was safely stopped on roadside emergency breakdown lane. This incident could have easily resulted in a collision with faster-moving traffic. The vehicle has been transported to a dealer for inspection to determine the cause, however this episode appears very similar to a documented issue in 2016 with a faulty fuel harness and low pressure fuel pump. No warnings or indications were present until after the car was turned off and restarted.

Veering right since new 7/2012 on freeway and city streets. Undercarriage right side "tweaked" per hyundai service rep in 2016. In shop since april 22 and out may 14, /2017 right control arm broken and coil spring bad (fixed per service rep), alignment still in red right front camber; steering wheel severely off center at times and now veers more to left and sometimes to right on city streets and highway; when coming to stop steering wheel becomes severely off center. In april 2017 was losing speed even though pressing on gas pedal and acting if wanting to stall several times with in a week (happening a few other times in past but thought due to being cold or bad gas.. When this happened psi light turned on. Happening on freeway and while merging onto freeway and other times on city streets. When this happened in april 2017 the last time with the wanting to stall problem steering wheel became really off center (dealer notified and taken to shop on 4/25/2017). Also would not go into reverse the same day of losing power wanting to stall. (happening a few other times in the past). Now AC air force low and doesn't cool as prior to being in shop 4/2017 and blows hot air at times. Airbag sensors not working properly as before shop visit 4/2017. Have had paint chipping problems on body of driver door and passenger door and around truck area. Has also had fuel pump issues, repeaired once (when pumping gas pump constantly clicking off). Poor suspension rear end feels like it bottoms out when going over bad road/bumps on freeway and city streets.

As I was driving down a major street traveling around 35 MPH, the car in front of me began to stop. As I began to apply the brakes, my car's pedal went to the floor. I pumped the brakes a few times and began to get some pressure, but I was not able to stop in time before rear ending the car in front of me. I never knew what the issue was and I couldn't get the problem to duplicate, but the brake pedal was soft since that day. I have changed the pads, and rotors, so those are not the issue. This week, my fuel pump went out and I took the car to the mechanic for that issue. My mechanic informed me that the car needed an ABS pump. The dealers are well aware of the issue because when we checked the price of the part ($2600), the parts agent immediately knew the problem. There are numerous complaints online about the exact same issue. This is truly a safety issue for these cars. There are many complaints online with the same problem!!!!!!!

Hyundai is having a real issue with their fuel pumps. My car is currently in the shop for its 3rd fuel pump at 120k miles. The safety issue is how the pump goes out with no indication of an issue from the car at all. This time I was parked at a gas station, however the 2nd incident is more concerning. Then, I was traveling on the highway at approx. 70-75 MPH. Without warning, the engine stopped and of course so all of the other controls from the engine. Because I had a full loss of power, I was lucky that there were no cars in the inside lane and I could move over in time to get to the side shoulder. I literally coasted to the shoulder at 20 MPH. If I hadn't been able to get to the shoulder, I would have been stuck in the middle of a 4 lane highway with no way to move the car.

Sudden loss of power at freeway speed. Driving at freeway speed late at night with adaptive cruise control on, I accelerated and changed lanes to the left to avoid a collision with an inattentive driver. Immediately after changing lanes to the right to return to my lane, the car stopped responding to throttle input. Rpm gradually decreased to zero and the car stalled. No warning lights until the engine stopped at the right shoulder of the freeway. I restarted the engine. Still no warning lights. The car entered a limp-home mode with max RPM around 1500, very slow acceleration, max speed about 50 MPH. It did not stall again during the 10 mile trip home. Towed to dealer. Dealer states that the obd2 fault code was p1230, low fuel pressure. The technician test drove the car and reproduced the behavior. Initial diagnosis was "failure of high-pressure fuel pump." today (5 days after incident) the dealer states that hyundai tech support recommends additional diagnostics prior to replacing the fuel pump.

I was driving on a major interstate, when the engine sputtered then shut off at highway speed. No warning from the instrumentation panel until after the engine failed. After stopping in the breakdown lane, I was unable to restart the vehicle. The service department at the dealership believes the incident was caused by a defective gas tank and is recommending replacement of both the tank and fuel pump.
