Ram 1500 spongy pedal problems

I am reporting a catastrophic, cascading electrical and mechanical safety defect involving the central electronic network, hydraulic braking system, and the supplemental restraint system (SRS) on a 2024 Ram TRX.In the week leading up to the collision, the vehicle exhibited persistent electrical anomalies, specifically where the primary display screen/infotainment system would suddenly crash and go completely black while operating. On the day of the incident, while traveling at approximately 55 mph, I attempted to apply the brakes to avoid an obstacle. The brake pedal immediately went completely soft and "spongy," providing no adequate hydraulic pressure or braking force to slow the truck.Due to this sudden braking failure, the vehicle sustained a severe, high-velocity front-end collision. The driver was properly wearing their seat belt at the exact time of impact. Despite massive front-end structural deformation directly inside the vehicle's primary sensor zones, the steering wheel, knee, and side curtain airbags completely failed to deploy. Due to this non-deployment during a high-speed impact, the driver sustained head trauma and was knocked unconscious. The vehicle subsequently rolled over, coming to a final rest overturned on its right side. The vehicle’s event data recorder (EDR) data buffer was later overwritten during subsequent post-crash handling/ignition cycles before data could be locked.The prior display blackouts combined with a simultaneous loss of braking pressure and restraint system failure strongly point to a systemic CAN bus or module power failure. I request a formal federal investigation into the electrical architecture, braking modules, and airbag control module (ACM) thresholds for this vehicle class.

I received recall notification number 24V653000, Stellantis recall 75B. This recall is detailed as a software malfunction in the ABS control module to disable the electronic stability control system. This will cause the vehicle to fail. It was serviced at Don Davis Ram dealership in Arlington, Texas on November 11, 2025 and was advised they were going to do a software update. On July 27th , I contacted (formerly Don Davis) now Clay Cooley Ram dealership and spoke to a service representative, Jose Hernandez. I explained that the brakes feel very spongy and takes more time to slow the vehicle down (constantly have to brake several times when approaching other vehicles or at red lights). It is very noticeable and is dangerous for me and others on the roadway. He explained that I am now responsible for the diagnosis evaluation of $99.95 plus the fee to update the EBS software. Jose explained that everytime the brake system needs to be updated, then I am financially responsible for these fees because the 36,000 miles warranty has expired. I explained to him that I am guaranteed a "Lemon Law" protection in my purchase. In addition, this vehicle only has approximately 28,000 miles

On Thursday [XXX] I was driving my new 1500 Big horn ram truck. I only had it for 6 days at that point. I started noticing a noise coming from inside the dashboard and the check engine light came on. I kept driving as usual because i figured the light would go off. All of a sudden a big metal ring the size of my palm fell on my shoe and all the warning lights came on the dash ( the brake failure light, adaptive cruise control unavailable light, parking sensor failure light, check engine light, traction control malfunction light, brake system light, abs failure light). When i tried to brake, the brakes went all the way down and felt very spongy. I had to pump the brakes just so it would stop. So I pulled over into a parking spot turned off the truck and started it back up. The truck started up, but all the lights were still on. I tried to shift into drive but it wouldn't go in gear. I think is because the brake weren't going far enough to push whatever sensor allows the shifter to shift. I tried pumping the brakes and shifting and it worked. So i drove the truck home very carefully and parked it in my driveway. The next morning I called my sales man and left him a msg. He called me later that evening and asked me to bring it in on Monday morning. I did not use the truck during the weekend because it felt very unsafe to drive. On Monday morning i drove it to the dealership and left it there. They did give me a loaner vehicle. 2 days later I got a call from Dave the service manager and he let me know that the ring that fell on my foot holds a brake pedal in place and that they were going to replace the entire brake pedal assembly, the abs module, the brake booster and some ecm (i didn't understand which one). This truck has been unusable now for 7 days and I've only owned it for 13 days. It's been in the shop for 5 days now.
