Service bulletins for the 2014 Ram 1500
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

The following powertrain system improvements/enhancements are included in this software release: ? Enhanced Automatic Oil Change Indicator(EAOCI) system enhancements that force the use of the severe duty cycle algorithm anytime the PCM is replaced. The vehicle duty cycle information used in the EAOCI calculation is stored in the PCM and cannot be recovered/transferred when the controller is replaced. As a result, the severe duty cycle is used in these scenarios to ensure the customer receives a timely oil change required message. ? Corrected a generic scan tool display issue regarding Mode 6 data accuracy. ? Improved transmission Quick Learn routine performance (Applies only to DJ vehicles) |
| P13040214 | 2022-08-29. Service bulletin. POWER TRAIN. New Safety Recall Advanced Communication ? P13040214 Chrysler Group LLC (Chrysler) announced a safety recall on certain 2014 model year (DS) RAM Truck (1500 series). The transmission case may have an improperly machined park rod guide plate mounting surface. This could cause a loss of park rod guide plate fastener clamp load and eventually the park rod guide plate fasteners may loosen. A loose park rod guide plate and fasteners may not allow the park pawl to fully engage. This condition could cause unintended vehicle movement and cause a crash without warning. Chrysler will conduct a voluntary safety recall on all involved vehicles to inspect the transmission case. Transmissions found with an improperly machined park rod guide plate mounting surface must be replaced. Dealers will be notified of the launch of this safety recall by way of established methods used in the past. We ask that you please take the time to ensure that your personnel are aware of this communication and are prepared to execute a customer friendly process for inquiries on involved vehicles. |

| 5RR541XRA | 2022-08-22. Service bulletin. POWER TRAIN; VISIBILITY; PARKING BRAKE. Power Fold Rearview Mirror Prior to replacing this part for a loose mirror, please first follow this procedure to reset the pivot mechanism. Move the mirror to its full forward position and then to full retract position using the power fold mirror button located on drivers side door panel. Perform this procedure three times. If this doesn't resolve the issue, then repair as necessary.~ Note: 1- The looseness of power fold mirror does not necessary indicate a defective mirror, it may be caused by folding it manually rather than using the power fold feature. If the mirror is adjusted manually out of the proper detent, always use the button to adjust it back into sync.~ 2- The intended use of the power fold mirrors is by pushing the button to fold and unfold the mirror. Only manually fold the mirrors when absolutely necessary.~ 3- In the circumstance where the left hand mirror and right hand mirror are in different positions, it may take up to three cycles (bottom pushes) to re-sync the mirrors together. |

| 68056356A | 2022-08-08. Service bulletin. EQUIPMENT; POWER TRAIN. Axle Assembly, Axle Carrier, Axle Ring and Pinion Engineering is currently investigating concerns with pinion seals on the 2014-15 MY Ram 1500 Pick-up with a rear axle manufactured within the October to November 2014 calendar year. Please contact Ridhan Riyal at cell (810) 513-3832 for further instruction. If he cannot be reached with 15 minutes proceed with your repair.~ The DS Limited Slip Differential operates as a torque sensing device because when torque is applied to the differential gear set the reaction forces of the bevel gears apply an axial force into the clutch system providing the torque bias. When the input torque is very low the reaction forces will decrease allowing the differential to ACT SIMILIAR TO A OPEN DIFFERENTIAL (zero preload). Please do not confuse this with prior model year Limited Slip Differentials. See the service manual for complete details. |
