| PI1187C | 2021-04-21. Service bulletin. VISIBILITY:REARVIEW MIRRORS/DEVICES; ELECTRICAL SYSTEM:ADAS:DRIVER MONITORING:CAMERA/SENSOR. Information on Inside Rear View Mirror and Camera Loose Some customers may comment that the inside rear view mirror or front camera is loose or that the mirror/camera mounting bracket is loose or has fallen off. If a vehicle is encountered with the above condition, do not attempt to reinstall the bracket onto the windshield. The above listed vehicles have a revised bracket design that is not serviceable. It is necessary to replace the windshield glass assembly. The bracket comes installed on the new glass assembly. Refer to Windshield Replacement in SI. |

| PI1002B | 2021-04-21. Service bulletin. STEERING:GEAR BOX (OTHER THAN RACK AND PINION). Grease or sealant visible on steering gear - should not be interpreted as leak. Some customers or technicians may comment on seeing grease or sealant on certain locations of the steering gear. The illustrations below include arrows showing the areas on the steering gear that the supplier intentionally applies sealing grease. Any of these locations have the potential of showing visible grease under normal operation. |
| 15-NA-082 | 2021-04-20. Service bulletin. SUSPENSION:FRONT. Clunking Noise from Front of Vehicle During Turns and/or Bumps Some customers may comment on a clunking noise originating from the front of the vehicle that is more predominant during turns or traveling over bumps. This may be caused by a damaged stabilizer shaft frame bracket. There have been some cases in which the bracket is cracked, as shown. This condition has been found to be the result of insufficient welds between the bracket and frame rail. There have been some cases on older vehicles of corrosion affecting the bracket |

Odometer setup at the electronic service center (ESC) when using an exchange IPC/DIC. 3. Tech 2® – The Tech 2 is used to set up a replacement BCM, which includes loading the odometer value that is displayed and stored in the IPC. A replacement IPC will display the previously stored vehicle odometer value, communicated from the BCM, after cycling the ignition or driving the vehicle. *The odometer programming is integrated as part of the BCM programming procedure. It is not a stand-alone event. |

| 15-NA-019 | 2021-04-20. Service bulletin. FUEL SYSTEM, OTHER. Fuel Odor During Fuel Filling or During Idle, Possible P0442 or P0455 DTCs Set Some customers may comment on a strong fuel odor during fuel filling or during vehicle idle. Cause This may be caused by the fracture or breaking of the gasoline filler neck recirculation line connector Correction If you encounter a vehicle with the above concern, complete the following procedure: 1. Raise the vehicle and visually inspect the fuel tank filler vent hose connector for damage. Refer to Lifting and Jacking the Vehicle in SI. • If connector is damaged, replace the fuel tank filler vent hose. Refer to Fuel Tank Filler Vent Hose Replacement in SI. • If there is no damage to the connector, continue diagnosis referring to SI. |

| 10-06-04-013C | 2021-04-20. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM; ENGINE AND ENGINE COOLING:ENGINE:DIESEL. Information on Diesel Exhaust Fluid (DEF) Filling Instructions, Frozen Tank Status and General Information In operating temperatures of 15°F (−9°C) or less, customers may comment on an “Exhaust Fluid Range” message displaying on the DIC even though the DEF fluid has been filled. When the DEF is frozen, the level sensor cannot determine the fluid level in the tank. If this occurs the logic of the PCM will assume a default fluid level. The logic will use the calculated range based on DEF dosing history and the assumed fluid level. If there is a high learned dosing rate and the fluid has not thawed to where the pins of the level sensor can function, there is a possibility the “Exhaust Fluid Range” message can set with the range from approximately 1609 km (1000 mi) to less than 482 km (300 mi), even though the tank is known to have fluid or be full. This is an operating characteristic of the system. However to increase or eliminate the range message, once the range drops below 482 km (300 mi), the DEF tank should be refilled. This should allow refill detection to occur and turn off the range indicator. The operator must be sure not to overfill the DEF tank using the instructions provided in this bulletin or in the owner’s manual. When in frozen tank status, refill detections are not allowed until the warning strategy reaches the point at which the distance remaining is less than 482 km (300 mi). The refill detection is dependent on the DEF thawing enough that the level sensor pins can be read. A fully frozen tank can take almost an hour to detect a refill, after the vehicle is started. This condition should not be confused with the situation described in PIP4864: Low Or Speed Limited Diesel Exhaust Fluid Message (DEF) Will Not Reset”. |

| PIP5163E | 2021-04-19. Service bulletin. FUEL SYSTEM, GASOLINE. This Preliminary Information communication provides information to the technician about engine block of possible cylinder bore damage, scoring or out of round as the possible cause of engine oil consumption, misfire, cylinder leakage or blow by. Technician will need to inspect the engine for Cylinder damage or scoring, An out of round cylinder bore, Dirt intrusion, and Catalytic Converter failure. |
| PIP5212C | 2021-04-19. Service bulletin. ENGINE AND ENGINE COOLING. This Preliminary Information communication provides information to the technician about vehicles that have run hot and or has a tick noise. Technician should inspect the head gaskets to ensure are not installed backwards. Technician should replace the head gasket if they are found installed backwards. |

| PIP5540G | 2021-04-19. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:OIL/LUBRICATION:PRESSURE/TEMPERATURE SENSOR. This Preliminary information communicates to the technician the need to inspect the induction system for potential icing issues in very cold ambient temperatures. To allow the ice to melt so that it can be drained from the related components. That any of the listed DTC's may set with or without poor engine performance. |
| PIP5725A | 2021-04-19. Service bulletin. EQUIPMENT. This Preliminary information communicates the use of Winter grade fuel during the warm months of 2020 and the potential rivability issues that it can cause. The ongoing Coronavirus (COVID-19) pandemic has caused significant reductions in driving and fuel use. Due to the surplus of winter grade fuel sitting in storage (pipelines/stations) the EPA is waiving the fuel vapor requirement. This will extend the use of winter fuel into the summer months. The drivability concerns should not be single events but should be multiple occurrences associated with hot days. |
| PI-1255F | 2021-04-16. Service bulletin. VISIBILITY:REARVIEW MIRRORS/DEVICES:EXTERIOR. Changing to Camper Outside Rearview Mirrors Some customers may request to have camper style mirrors installed on their vehicle. The new electrical architecture for the Silverado and Sierra has made swapping mirrors a more involved procedure than with previous models. The recommendation has been divided into three upgrades, depending on which mirrors the truck was built with (RPO DE2, DL8 or DL3). Please follow the correct RPO group below, because not all camper mirrors can be installed on all trucks. After selecting the correct RPO mirror the truck was built with, this PI will aid in determining which camper mirrors can be installed. |
