Fuel pump on other Sonata years
No other Sonata model year has enough reports of fuel pump for a sheet of its own. See every Sonata year.
What this problem usually is
A lot of fuel pump complaints are tied to a recall. Owners describe a car that stalled or wouldn't start, sometimes at highway speed, and many mention that a recall covers it and the part isn't available yet. Others paid for the pump themselves before a recall existed, or on a car the recall didn't include.
What got replaced
Owners who name the part that was replaced mention the fuel pump (30 reports) and the high-pressure pump (3 reports).
Recalls and investigations
One recall on the fuel and propulsion covers the 2015 model year. A recall on the same system isn't always the same failure, so read the defect text.
The affected vehicles may have been assembled with an incorrect left axle shaft which may result in the shaft separating from the transaxle differential.

Is this a known problem?
The manufacturer has sent NHTSA 1 service bulletin or notice for the 2015 Hyundai Sonata that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.
Certain 2015-2019MY Sonata (LFA) vehicles may intermittently exhibit reduced engine power, a âCrank/No Startâ condition, and/or have DTC P1233 stored in the ECM due to an internally leaking fuel pump filter housing.

Should you keep driving it?
This page can't tell you that. 0 of 30 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
