A model year appears here because the code is named in its record, not because every one of these vehicles sets it. Counts are mentions in the federal files, not failure rates — nobody publishes the denominator.
What it gets filed under
What owners said
Source: NHTSA complaint databaseOwners’ own words, one per nameplate, scrubbed of anything identifying. These are unverified reports filed with NHTSA — they are what was said, not a finding that it was true.
The vehicle was taken to a local Auto Zone and a diagnostic machine retrieved DTC: P0191
Sixteen trouble codes were stored, including P26A6, P0606, P060B, P2138, P2135, P2122, P2119, P2004, P2005, and P0191
The onboard diagnostics code P0191 was reported following the April 2026 event, however no codes or errors were identified by the Hyundai technician following the November 2025 event
Diagnostic trouble codes P0191, P2177, and P2179 were later identified, indicating fuel pressure irregularities and air/fuel imbalance
The fuel delivery system, specifically the fuel pump and fuel rail pressure system, has malfunctioned and continues to trigger diagnostic trouble code P0191 (fuel rail pressure sensor range/performance), despite a prior recall-related…
Manufacturer filings that name it
Source: NHTSA manufacturer communicationsService bulletins and campaigns whose filed summary names P0191. Quoting the document number at a service desk is often the fastest route to a diagnosis someone has already written down.
- PIP61132026-05-19 · Unknown Or Other
- This document provides the technician with a diagnostic tip if the vehicle stalls and set diagnostic trouble code P0191 and may also set P0172. The diagnostic tip has the technician inspect the high pressure fuel pump body markings to confirm it is an original manufacture part. If it is not an original manufacture part, they should install one and evaluate the vehicle.
- TSB_2067757_42026-03-20 · Engine
- This bulletin provides information when there is a drive system fault/engine won't start; either no DTC, or DTC P0191, P0087.
- PIP5151F2018-07-30 · Fuel System, Gasoline
- This Preliminary Information communication provides information to the technician about vehicles that may have a hard start, no start, rough running, or low fuel pressure. Technician may find Diagnostic Trouble Codes P0087, P0088, P0191 and P128E during the inspection. If during the inspection of the fuel system contamination is found the complete fuel system will need to be cleaned and flushed. A

What P0191 means
Source: SAE J2012 / OBD-IIThe fuel rail pressure sensor reading does not track the commanded pressure.
A stored code names the test that failed, never the part that caused it. It is the starting point of a diagnosis, not its conclusion — the same code has several possible causes and the cheap one is not always right.
Common questions about P0191
Source: NHTSA files and the OBD-II standardCan I keep driving with P0191 stored?
Nobody can answer that from the code alone, and a site that does is guessing. A steady light generally means the fault was logged and the vehicle is in a reduced-risk mode; a flashing light means stop soon, because a misfiring engine can destroy a catalytic converter in minutes. The safe read of this page is the mileage and the components, not permission.
Does a code mean the car is recalled?
No. Recalls are filed by campaign and matched by VIN, and none of them are triggered by a scan tool. If you want to know whether an open recall applies to one specific vehicle, check the VIN at nhtsa.gov/recalls — that is the only source that settles it.
Why do the counts here differ from other sites?
Because these are not estimates. Every number on this page is a count of documents in NHTSA's own files: manufacturer communications that name the code in their filed summary, and owner complaints that name it in the narrative. We do not model, weight or extrapolate them.
Will clearing the code fix it?
Clearing turns the light off and erases the freeze-frame data a technician would have used to work out what happened. If the condition is still there the code returns, usually within a few drive cycles, and the diagnosis now starts from less information than before.
