Vehicle was started for the second time that day on 1/5/26 and the engine light was on. I drove the vehicle to an auto parts store to have them check it with an OBD-II scanner. It had code P050F. I had no idea how serious this issue could be at the time. I made an appt with the GMC dealership and dropped it off the evening of 1/6/26. They said there was a software anomaly in the engine control module and needed to be reprogrammed. I paid the $200 diagnostic fee for them to reprogram it. I learned that this anomaly could have caused my brakes to not work while driving it. I had been driving the vehicle back and forth to work until I dropped it off. This issue could have caused serious harm or…
On approximately 09/04/2026, while driving my vehicle and slowing to a stop, I applied the brake pedal and it suddenly became extremely hard to depress. At approximately the same time, the steering became very stiff and difficult to turn. I believed I had lost normal braking ability and had difficulty controlling the vehicle while attempting to stop. The engine then shut off on its own. After the vehicle stopped, attempts to restart it were unsuccessful. The engine would crank/attempt to start but would not complete the ignition cycle and remain running. A ticking noise was also present. The vehicle remains available for inspection and is being towed to a local GM dealership for diagnosis…

Engine light went off. The other diagnostic by my mechanic showed the Oil Control Intake and Exhaust Variable Valve Timing (VVT) Solenoid needed to be replaced too.

I GOT A DIAGNOSTIC ALERT: SERVICE THE ENGING AND TRANSMISSION SYSTEM IN YOUR 2018 TERRAIN WITHIN 7 DAYS. THE CODE WAS P050F. I HAVE A LITTLE OVER 10,000 MILES ON HERE.
PURCHASED A BRAND NEW GMC TERRAIN. 12 DAYS AND 460 MILES LATER THE SERVICE ENGINE SOON LIGHT CAME ON. TOOK IT TO DEALERSHIP FOR A P050F. THIS IS CODE FOR A LEAK IN THE BOOSTER. THEY DID NOT REPAIR ANYTHING, JUST CHECKED FOR LEAK AND RESET ENGINE LIGHT. AS I READ MORE, THE PROBLEM AFFECTS THE BRAKES ABILITY TO FUNCTION PROPERLY INCREASING DANGER TO DRIVER. THERE IS ALSO DEFECTIVE STOP/IDLE ON THE ENGINE THAT NO LONGER WORKS. I WAS JUST DRIVING DOWN THE ROAD IN TOWN WHEN IT POPPED ON. GM AND YOUNG'S HAVE REFUSED TO REFUND THIS DEFECTIVE VEHICLE.
P050F: questions drivers ask

Is there a recall for code P050F?
No NHTSA recall text names P050F directly. 1 recall on the cars that report this code concerns the same component owners name most (Service Brakes); they may or may not relate to the code. Check your VIN at nhtsa.gov/recalls.
What should I do if my car shows P050F?
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.
How this page was made
CarHooq read the text of every owner complaint filed with NHTSA for 19 US and European brands (model years 2012 onwards) and picked out the diagnostic trouble codes owners wrote down. This page lists every mention of P050F. Manufacturer codes have no public standard definition, so CarHooq shows only what owners reported. Nothing here is a diagnosis.
