The high-pressure fuel pump/fuel delivery system failed on my 2023 Chevrolet Traverse at approximately 47,480 miles. The vehicle generated diagnostic trouble code P0091.

This failure presents a significant safety concern because the high-pressure fuel pump is responsible for maintaining proper fuel delivery to the engine. Failure of this system can result in hesitation, reduced…
WE HAVE HAD OUR 2016 YUKON XL FOR ALMOST 2 YEARS. LAST YEAR WE STARTED EXPERIENCING EPISODES WHERE THE VEHICLE WILL SHIFT DOWN INTO REDUCED POWER MODE WITH P0090 AND P0091 AS THE FAULT CODES. WE HAVE BEEN WORKING WITH THE DEALER, BUT ONCE THE VEHICLE HAS BEEN TURNED OFF FOR ABOUT 20 MINUTES OR SO IT CLEARS AND LEAVES NO TRACE OF AN ISSUE. THIS IS EXTREMELY DANGEROUS AND RECENTLY SHIFTED INTO REDUCED POWER LEAVING US ONLY ABLE TO DRIVE 35 MILES PER HOUR.

P0091: questions drivers ask
What does code P0091 mean?
P0091 is a generic OBD-II powertrain code. Its standard definition is "Fuel Pressure Regulator 1 Control Circuit Low". The code tells you which system set the fault, not which part failed; the owner reports on this page show what it meant in practice for 3 car models.
Which cars get code P0091 most often?
In NHTSA owner complaints, P0091 is mentioned most for the Chevrolet Traverse (2), GMC Yukon (1), GMC Yukon XL (1), across 3 models and model years 2016 to 2023. Popular models collect more reports because more of them are on the road.
Is there a recall for code P0091?
No NHTSA recall text names P0091 directly. 1 recall on the cars that report this code concerns the same component owners name most (Fuel System); they may or may not relate to the code. Check your VIN at nhtsa.gov/recalls.
What should I do if my car shows P0091?
Write down when the code appeared and what the car did (warning lights, loss of power, noises, speed, weather). Check your VIN for open recalls at nhtsa.gov/recalls, ask a dealer or independent workshop to read the stored freeze-frame data before anyone clears the code, and keep the repair order. If the car loses power in traffic, stop driving it. CarHooq does not diagnose: these are owner reports and official recall notices, not repair advice.
