What is the 2014-2018 GMC Sierra 1500 Unintended braking on one wheel after a wheel-speed sensor fails — recall 19V761?
GM found that if a wheel-speed sensor fails, incorrect axle-ratio calibration in the electronic brake control module (EBCM) can activate the driveline-protection system while driving 41-60 mph in four-wheel drive or Auto mode, braking the wheel on the opposite side and pulling th… Severity: high.
What is the 2014-2018 GMC Sierra 1500 Harder brake pedal as the engine vacuum pump weakens — recall 19V645?
GM found that the engine-mounted mechanical vacuum pump's output may decrease over time, reducing power brake assist. GM says debris such as oil sludge can build up on the pump's oil filter screen; drivers may notice increased pedal effort, a hard pedal or a longer stopping dista… Severity: high.
What is the 2014-2015 GMC Sierra 1500 Automatic transfer case can shift to neutral on its own — recall 14V374?
GM found that an electrical signal short may cause the automatic transfer case to switch to neutral without driver input, while the mode knob still shows the last mode. While moving, the truck loses drive power; parked without the parking brake set, it can roll. 2014 GMC Sierra 1… Severity: high.
What is the 2014 GMC Sierra 1500 P0700 transmission fault request — diagnose the accompanying TCM code?
GM explains that P0700 stored in the engine controller accompanies a transmission-controller concern and another diagnostic code. P0700 alone does not identify a failed transmission module or justify replacing the engine controller. 2014 GMC Sierra gasoline LV3, L83 and L86 confi… Severity: high.
What is the 2014-2019 GMC Sierra 1500 Misfire or ticking from a collapsed or stuck AFM lifter — bulletin 15-06-01-002O?
GM says a misfire, tick noise and check-engine light with P0300 may be caused by an Active Fuel Management lifter that is mechanically collapsed or stuck, internal locking-pin damage from oil aeration, a lifter collapsed and stuck in its bore, or a bent pushrod. 2014 GMC Sierra 1… Severity: high.
What is the 2014-2019 GMC Sierra 1500 Intermittent crank-no-start with P0011 from a sticking cam actuator solenoid — GM information PIP5130K?
GM tells technicians that the camshaft position actuator solenoid valve may stick or bind, holding the valve timing retarded, which can cause an intermittent crank-no-start with code P0011 and/or P00C6 stored. GM says the engine may sound like it is cranking fast and fuel rail pr… Severity: medium.
What is the 2014-2018 GMC Sierra 1500 P0430 catalyst code: check air-cleaner sealing before replacing parts — GM16-NA-111?
GM says sand or debris can enter the air filter box and bypass a poorly sealing air filter, damaging the oxygen sensor element and blocking the catalytic converter with sand and debris particles, which turns on the check-engine light with P0420 and/or P0430. 2014-2018 GMC Sierra… Severity: medium.
What is the 2014-2015 GMC Sierra 1500 Warm A/C from a leaking compressor-to-condenser line — GM PIT5331?
GM describes warm A/C and very low or empty refrigerant when a small crack or pinhole forms at the first bend of the compressor-to-condenser line. Oil and refrigerant on the compressor can make the leak source hard to identify; this is not evidence that the compressor itself fail… Severity: medium.
What is the 2014-2018 GMC Sierra 1500 Rough idle, misfire or hard starting from carbon on the valves — bulletin 16-NA-383?
GM says major carbon build-up on the intake and/or exhaust valves, from fuel contamination or incomplete burning of the fuel, can cause rough idle, extended crank, crank-no-start or misfire with codes P0300-P0308, and that valves may stick. 2014-2018 GMC Sierra 1500 gasoline engi… Severity: medium.
What is the 2014-2018 GMC Sierra 1500 Catalyst codes P0420/P0430 from dirt getting past the air filter seal — bulletin 16-NA-111?
GM says sand or debris can enter the air filter box and bypass a poorly sealing air filter, damaging the oxygen sensor element and blocking the catalytic converter with sand and debris particles, which turns on the check-engine light with P0420 and/or P0430. 2014-2018 GMC Sierra… Severity: medium.
What is the 2014 GMC Sierra 1500 4.3L V6 crank/cam correlation code P0016 from a loose crankshaft reluctor wheel — GM information PIP5183?
GM told technicians that on the 2014 Sierra 1500 with the 4.3L V6, service-manual diagnosis may not find the cause of a hard P0016, and that the crankshaft reluctor wheel may be damaged, misaligned or moved on the crankshaft. 2014 GMC Sierra 1500 with the 4.3L V6 (RPO LV3), per G… Severity: medium.
What is the 2014-2015 GMC Sierra 1500 Grind, pop or bind in the steering column when turning — GM information PIT5312B?
GM tells technicians that a grind, pop, shudder or bind felt or heard in the steering column when turning can come from the lower column bearing housing being out of position, or from the upper intermediate steering shaft-to-column bolt and nut contacting the shifter cable bracke… Severity: low.
What is the 2014-2015 GMC Sierra 1500 Fuel odor and EVAP leak codes from a cracked filler vent hose connector — bulletin 15-NA-019?
GM says a strong fuel odor during fueling or at idle, with possible P0442 or P0455, may be caused by a fracture of the gasoline filler neck recirculation (vent) line connector. 2014-2015 GMC Sierra 1500 except Regular Cab, per GM bulletin 15-NA-019 (December 2015). Severity: low.
What is the 2014-2015 GMC Sierra 1500 Check-engine light or hard-to-fill tank from a dirty or wet EVAP vent valve — bulletin 15-06-04-002?
