2026 Ram 3500 with <2700 miles. The trailer brakes are not applied appropriately when using the brake pedal, even though it will brake appropriately (with 1 of 3 trailers) while squeezing the manual override. This includes all brake levels (1-10 gain). When the trailer is disconnected, the truck will brake and show the appropriate level of pressure on the dash, though when the trailers are connected, one might press their foot 50% of the way down on the pedal while only 5% of the pressure is displayed on the dash and applied to the trailer brakes. This has nearly caused 3 separate accidents while towing (16,600 pounds total) when people merged and braked hard in traffic. Ram dealership initially refused to investigate until persisting and becoming very angry. At that point, the issue was confirmed. Brake module parts are pending replacement at this time. Their current "test methods" don't include an actual trailer and are insufficient to diagnose and identify the issue. There is no doubt that this will kill someone at some point. There was eventually a service trailer brake system message that popped up, though this wasn't persistent and went away automatically, not stored permanently, when the trailer disconnected. This message appeared previously approx 3 times, though there was no trailer connected to the truck at the time. Proximity sensors in the front and rear are also faulty, delaying notification of item in proximity, not displaying at all, or randomly being accurate. It also detects traffic that is a significant distance away. The same Ram dealership repeated the issue and called this "normal or expected behavior". It is, most definitely, not, and may present a danger to small children walking around the vehicle, pets, or potentially property due to the lack of notification of objects present.
NHTSA complaint #11758110 — an unverified report by a vehicle owner.
Started with only 320 miles just days after purchasing this new 2026 RAM 3500 on XXX. I have taken the truck to three differ RAM dealerships as this issue continues to occur. [XXX]; [XXX]; and [XXX] Westside all had attempted to fix the issue. I had to return the truck a number of times to [XXX] and [XXX] for the same reasons. The following warmings messages are displayed: FCW/Cruise Control Unavailable Service Required - occurs when using cruise control, Service Electronic Stability Control, Auto Emergency Braking (AEB) Unavailable Service Required, Park Sense Temporarily Unavailable, Service Antilock Brake System, 4WD System Temporarily Unavailable, and Service engine light comes on. Two RAM dealers are saying the issue is the speed sensor, which has been replaced over three times. The RAM dealership had to open an engineer ticket with the manufacture, but the issue is not fixed. The Jacksonville service manger told me I can keep bringing the truck in, but until a different manufacture makes a new speed sensor, the truck will continue to have the same issue. I use the RAM 3500 to pull my RV. Brake system failure put myself and family and others safety at risk while on the road, therefore, I do not drive the truck in fear the brake system will fail and I won't be able to stop 20,000 pounds of truck and RV. The truck is available for inspection, but I am currently in the process of returning the truck under Flordia's Lemon Law.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
My ABS hydraulic control unit pump motor is not working properly. This has been affecting me since Oct 2024 when we were pulling our 5th wheel and losing braking and power. I learned later that It is part of a NHTSA Recall 24V-896000. Code C4B I was told by the Dodge dealer Jack Powell in [XXX] that I was on waitlist when I reported it to them 12/19/2024. During the next several months I always got the same answer so then filed a case on 7/7/2025 with the FCA. Case #XXX. During many calls after, and including the last call on 3/27/26 that the part was not available, that this was a National backorder with no ETA. I filed another case on 8/17/25 for a rental vehicle - case #XXX. After several calls I got that approved. The Dodge dealer diagnosed my truck with that active code in place. Also to be clear, the dealer has confirmed failure of the ABS system, which disables safety features Due to this defect, the truck can lose ABS braking, tractional control and electronic stability control. The dash warning lights come on all the time, with the sound too. Although I was approved for a rental vehicle, that is for $60 per day and only for a non-tow vehicle. The problem is that this vehicle is primarily used for towing. I have a 5th wheel hitch and use it for towing our 5th wheel trailer, that we purchase early 2024. We tow our boat as well. The bigger problem is that I am near retirement and we are not able to use our 5th wheel for the trips to prepare for that and the plan to travel once I retire later this year. I need to have a functionally comparable vehicle that is equipped for 5th wheel towing as a rental or reimbursement. I would also like a review for alternative remedies due to the unreasonable delay in completing the safety recall. When I contacted Stellantis on 3/27/26 I was told her was no buyback option and they would escalate to the rental dept for my concerns The vehicle is available for inspection upon request.

We have been waiting for almost two years for the traction control and ads break repair. When will something be done about this recall not being repaired?
NHTSA complaint #11725336 — an unverified report by a vehicle owner.
Shortly after purchasing a new 2026 Ram 3500 in January 2026, the vehicle began displaying multiple safety warnings simultaneously while driving. Warning indicators included Check Engine, ABS, Brake, Traction Control, Electronic Stability Control, Forward Collision Warning, and Automatic Emergency Braking, along with a “Service Electronic Stability Control” message. The vehicle had very low mileage when the issue first occurred. The vehicle was taken to the dealership for diagnosis and repair. The dealership indicated the concern involved rear wheel speed sensor(s) and the vehicle’s electronic control systems (including a Body Control Module software update). Multiple repair attempts were required, including sensor replacement(s) and software updates, with manufacturer engineering involvement. The dealership and engineering instructed extended test driving (hundreds of miles total) to verify the repair. A particularly concerning element is that a replacement sensor reportedly failed without producing a diagnostic code, meaning the driver may have no warning that a critical component failed until safety systems disable or the vehicle behaves erratically. When the issue occurs, multiple safety systems are impacted at the same time, including ABS braking, stability control, traction control, and AEB/forward collision systems. Multiple safety systems disabled simultaneously. Dealership personnel also indicated that these wheel speed sensors are experiencing widespread failures and that replacement sensors can fail again shortly after installation as they have a 67% failure rate, which raises concern that this may represent a broader manufacturing or component defect affecting multiple vehicles. This complaint is submitted to document a potential safety defect affecting braking, stability control, and driver assistance systems.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
RAM 3500 truck was purchased in Ventura, CA and has experienced multiple electrical and drivetrain failures beginning shortly after purchase. In January 2025 while traveling in Oregon, the infotainment system repeatedly blacked out and the cruise control button stopped functioning. A dealership replaced the cruise control button, restoring cruise control, but the infotainment problem remained. When the vehicle was returned after the repair, a new defect appeared: the horn button no longer worked. Loss of the horn creates a safety risk because the driver cannot warn other vehicles or pedestrians. Around 20,000 miles during a routine service visit at the selling dealership in Ventura, we reported a driveline vibration. The dealership and the upfitter inspected the vehicle and observed tire cupping. They checked the tires for premature wear and recommended overinflating tires as a remedy. The vibration continued and worsened, the infotainment failures persisted. In October 2025 while driving in Wyoming, the vehicle experienced a major drivetrain failure involving the front differential and axle assembly and required towing. The truck was first towed to the Yeti dealership in Afton, Wyoming, which closed shortly after the vehicle arrived. The truck then had to be towed again to Yeti dealership in Jackson Hole. There, technicians diagnosed front differential and axle assembly as the primary failure and also observed premature wear on aftermarket shocks installed by the upfitter. Technicians indicated the differential assembly was not readily available and would require special order. The vehicle was later transferred to another dealership in Dodge City for repair, but the differential components were not immediately inspected or ordered, causing additional delay. The vehicle remains out of service awaiting drivetrain repair. Safety concerns include horn failure, repeated electrical malfunctions, and drivetrain failure while driving.

While driving, the instrument cluster/odometer intermittently flashed and became difficult to read for ~15 minutes. After parking, the odometer continued flashing for ~10 additional minutes. After the flashing stopped, the vehicle displayed “ParkSense Unavailable – Service Required.” On a separate date, with no trailer connected and without pressing steering wheel buttons, the cluster displayed a “Blind Spot Alert – Trailer Type (Conventional/Goose/5th) – Press OK to Select” prompt. These events were captured on video. Safety risk: driver information/warnings become unreliable while the vehicle is in motion, which is distracting and may reduce awareness of speed/vehicle status. No crash, injury, or fire occurred. A dealer inspected the vehicle and reviewed the customer video. The dealer documented stored electrical/communication/configuration faults consistent with the concern, including ECU configuration mismatch, lost communication with the trailer interface module, and communication bus off faults. The dealer performed software updates to related modules and road tested ~34 miles; the concern did not reproduce during the test drive. The vehicle also has an open safety recall (NHTSA 26V-059 / FCA 03D) for the trailer tow module with remedy/parts pending. Incidents occurred on 02/16/2026 and 02/18/2026 at ~3,000 miles, including after cold/rain conditions. One restart sequence did not immediately stop the flashing. Dealer scan recorded the following (stored) DTCs: TIPM B2204-87 (ECU configuration mismatch), TIPM U116B-00 (lost communication with trailer interface module), and ITCM U0077-00 (communication bus off). Dealer performed module software updates including CADM update per TSB 08-020-26 and PCM update per RRT-26-036. Recall remedy for 26V-059 / FCA 03D remains pending parts.

Multiple times at random the vehicle will display an alert on the dash that the 4X4 system, anti lock breaks, adaptive breaking as well as forward and rear collision sensors and cruise control are all disabled. This has happened 5 times now. I have taken the vehicle into the dealership and they stated that the rear Wheel Speed Sensors" were bad and replaced them. Since the wheel sensors have been replaced ( less than 200 miles ago) this system has triggered the same alert and conditions 2 more times. This is a very dangerous situation for a vehicle that is made for towing heavy trailers and loads.
