Is my Hyundai Elantra N stalling because of the high-pressure fuel pump?

Short answer: Stalling, rough idle at stops and lost exhaust pops on an Elantra N can point at the high-pressure fuel pump. Run your VIN for Hyundai's fuel pump recall 24V528000 (2022-2023), where dealers update the engine software and replace the pump if needed, for free. Owners who swap pumps themselves should be careful with the O-ring.

Symptom: The engine stalls easily at low rpm, idles rough or feels like it will die at stops, loses power, or N mode stops popping.

What to check first

1. Run your VIN at nhtsa.gov/recalls for 24V528000.
2. Have codes read before resetting the ECU.
3. Note when it stalls: cold, hot, at stops, pulling away.
4. If swapping the pump, oil the O-ring and check the gasket.
5. Look for oil around the pump mounting.

Likely causes

1. Failing high-pressure fuel pump. The high-pressure fuel pump (HPFP) is driven by the engine and squeezes fuel up to the very high pressure the direct injectors need. When it can't keep up, the engine stalls easily, idles rough or loses power.
2. Recall software not done. Hyundai's recall for 2022-2023 Elantra N updates the engine software and replaces the fuel pump if needed.
3. Bad pump installation. Owners who swapped pumps tore the O-ring, a rubber seal that keeps oil in where the pump mounts, causing leaks.

What it usually costs

The recall work is free. Owners who upgraded to Sonata or G70 pumps paid for the part themselves. Exact prices weren't posted.

Is it safe to keep driving?

Stalling in traffic or losing power is dangerous. Get the recall done and have it checked soon.

DIY or shop?

Swapping the pump is DIY for experienced owners, but leaks and O-ring damage are common mistakes. Recall work is a dealer job.

What owners report

• In Exhaust pops are gone. Signs of a failing HPFP? on Reddit r/ElantraN, an owner's car idled hard and felt like it would stall when coming to a stop, and N mode stopped popping. Owners linked it to a failing HPFP and the recall's ECU update, and the owner planned to have codes read.
• In Do the 24/25 models still have the HPFP issues? on Reddit r/ElantraN, a 2025 owner asked if the newer models still have HPFP issues. Owners said 2024-2025 cars came with the ECU fix and that older cars were fine after the recall, though one said it's the same pump and can still fail, and they upgraded.
• In Hpfp O-ring failure on Reddit r/ElantraN, an owner of a 2023 with 36,000 miles who was going the G70 pump route found a torn, failed HPFP O-ring. Others said it looked like it had been installed incorrectly, and the owner asked whether dealers inspect the pump during the recall.
