    The EGR cooler bypass control broke on my pickup. The dealership stated that this is an ongoing issue with these pickups and that the 2019-2020 pickups had a recall on this. This pickup has 77,000 miles on it. This should not be failing.

    Electrical system shutdown including loss of all safety features (blind spot, emergency braking, abs, traction control, towing), climate control options (AC, Heat, window operations) and user interfaces (U-Connect screen, center gauge cluster). Initial warnings (2) on center cluster on listed- 1. Blind Spot Detection Disabled 2. 115 Volt Cargo Power Outlet On All electronics, controls were then disabled- black screens, inoperable controls. Passenger rear windows, sliding back glass, panoramic sunroof and drivers side mirror are the only working electronics other than speedometer. Upon inspection of all fuses, relays, battery, alternator, and checking all accessible wiring related to blind spot and auxiliary power and finding no defective issues, web searches were performed. Based on numerous other RAM owners on multiple forums on RAM trucks 2020 and newer with blind spot avoidance, we found a likely culprit in the driver's side brake light. Upon inspection of the left rear brake light assembly, a small hairline crack was located with signs of internal moisture/ condensation. After observing the internal moisture the drivers side rear brake housing was removed and disconnected for closer inspection and potential repair. While the driver side brake light assembly was removed, an instance occurred when my wife needed the vehicle. Upon and during the entirety of operation over the next 1.5 hrs driving approximately 63 miles, all electrical options worked as intended minus the blind spot avoidance and a new warning on brake lamps (obvious as tail light had been removed). During this time, the proximity sensor housing was removed from the assembly, water accumulation dried, and allowed to remain open next to a dehumidifier for 4 hours. Epoxy was applied over the hairline Crack, and any area that looked as if could be affected. Unit was reinstalled, however all electronic failure returned. Unit removed again to attempt humidity removal- all electronics res

    Our alternator is bad in a 2021 Ram. There are 10,000 on back order and up to a 9 -12 month wait list. There is obviously something wrong with this brand and should be recalled.

    RAM's 2023 recall addressed the engine shutdown problem in 131,700 of its half-ton 1500 RAM trucks equipped with the 5.7-liter Hemi eTorque mild hybrid engine. RAM said 1,500 5.7-liter eTorque models built between June 3, 2020, and September 12, 2021, had faulty software and needed a powertrain control module calibration update to fix the problem. Consumer complaints also exist that the RAM eTorque system has caused vehicles to shut down while in motion, which is by far the most dangerous problem attributed to it. My truck was built 08/2021
