2018 Ram 1500 transmission problems

Filed Oct 12, 2026 · Brakes, Steering · TX

San Antonio Tx was driving this morning in a light mist had my son in the truck the vehicle ahead of me came to an abrupt stop and I had to hit my brakes pretty hard and without the abs working properly I am impacted by the ABS controller failure However, I was surprise at how few have files formal NTHSA complaints on a serious issue that appears to impact thousands of trucks prior to 2019. The only way to move this ball forward and get injunctive relief is to inform NTHSA. To Whom It May Concern at the federal safety agency, I am filing this safety complaint regarding a defective ABS Hydraulic Control Unit (HCU) on my 2018 Ram 1500 TRADESMAN CREW CAB 4x4 5.7L Hemi with approximately 200,000 miles. DEFECT DESCRIPTION: The ABS HCU has failed, resulting in complete loss of anti-lock braking, traction control, electronic stability control, 4WD and cruise control. This is an identical failure mode to the defect addressed under the federal safety agency Recall 24V‑896, which covered 2017-2018 Ram 2500-5500 trucks. My 2017 Ram 1500 uses the same or substantially similar HCU component and is experiencing the identical failure. SAFETY RISK: The loss of ABS, ESC, 4WD and traction control significantly increases the risk of a crash, particularly in adverse weather conditions. This is not a minor inconvenience — it is a serious safety hazard that FCA/Stellantishas already acknowledged in heavier-duty Ram platforms. MANUFACTURER KNOWLEDGE: FCA was aware of this defect as early as 2016 based on warranty claims and customer complaints. Despite issuing Recall 24V‑896 for heavier Ram trucks with the same HCU failure, FCA has failed to extend recall coverage to the 2018 Ram 1500, leaving thousands of owners without remedy. FINANCIAL IMPACT: Repair estimates range from $1,200 to $2,000. The part remains on backorder or engineering hold, making timely repair impossible through normal channels. REQUESTED ACTION: I respectfully request that the federal safety agency: 1. Open a formal investigation into the 2017 Ram 1500 ABS H

XXX, [XXX] East Bound ~ 9:30 PM, , pulling a tandem-axle boat and trailer ~ 6000# GVW , the truck slowed suddenly, in traffic ~ 62 MPH. I contacted CJDR dealers in [XXX], and [XXX], and both stated there was no recall, warranty, or goodwill repair, available for my truck. [XXX] told me the same, when I called. I took the truck to an independent diesel shop, in [XXX] to just go ahead and have a CPS (crankshaft position sensor, and tone wheel) put in. He said both the CJDR dealers and Stellantis told him the truck was “ineligible” for the repair parts kit – he was unable to obtain one. They claimed *my* truck did not have the faulty tone wheel assembly. In the mean time, the code he documented P0335, did not return, and I continued to drive the truck, until XXX, 11:00PM I-4 [XXX] about the 106MM, the truck did the same thing, same trailer, same danger. After restart, limping home, OBDii code P0335, was present. On XXX, I took the truck for diagnosis, to New Smyrna CJDR, and they completed replacement of the CPS and tone wheel, today, XXX. The repair cost me $3,470.98 on Invoice Number XXX. I purchased the truck from New Smyrna CJDR, three months after it was built, which was two days before the production line started using the new design of CPS tone wheel. Stellantis knew, and the dealer knew. Still, they sent me off down the road. I would like to be reimbursed. Please find invoices from New Smyrna CJDR and Reed’s Garage.

My 2018 Ram 1500 Ecodiesel failed during acceleration on a busy freeway at 70 mph. I was able to avoid traffic and coast to the right shoulder. After paying for a tow, my scan tool called out four permanent codes: P0336, P061C, P062B, and U1401, proving the unsafe stall was directly caused by a delaminated or broken tone wheel. This failure is the root cause behind my open safety recall 66A. However, recall 66A only calls for a software fix and does not address my hard no-start condition. Since my Ram 1500 was manufactured in April of 2018 and the X94 warranty extension cut off date is March 26, 2018, I have no recourse to force FCA to address my failed tone wheel related to and actually the root driver behind the 66A safety recall. I intend to request FCA perform a "Goodwill" repair of the tone wheel. My complaint is I do not have a way forward to get my truck road worthy and safe under recall 66A. FCA cannot perform 66A on my Ram since the software repair cannot be completed while the truck is in a hard no-start condition due to the root driver behind the 66A safety recall. I should not be required to pay for a component known by FCA and the federal safety agency to be the actual cause behind the safety recall.

The contact owns a 2018 Ram 1500. The contact stated that while the vehicle was turned off and in park(P), the gear shifter could be moved out of the park(P) position without depressing the brake pedal. Due to the failure, the vehicle would roll forward which caused a potential safety hazard. Upon investigation, the contact discovered the federal safety agency ID Number: 18V100000(Power Train); however, the contact's VIN was not included in the recall. The vehicle had yet to be serviced or diagnosed for the failure. The dealer nor the manufacturer had been notified of the failure. The vehicle was not repaired. The failure mileage was approximately 52,000.

I am attempting to have my vehicle repaired for a defect in the rear axle that Recall U88 addresses and that my VIN falls within the range of. I am being told by the my local dealership and the FCA that my Vin has not active recalls. Does my vehicle fall within the recall? The recall is from 2018 the year it was built. Is it possible the system just doesnt go back that far anymore? Can someone please clarify. Thank you

Check Engine Light comes on and off on its own. OBD read that the engine is not getting up to normal temp. Had it diagnosed and was told that the 3.6 V6 has issues with the oil filter housing cracking/leaking. Somehow the housing cracking caused me to lose coolant. To have everything repaired would be $1400.

Took excellent care of my truck, doing all recommended maintenance and replacing parts as they wear out. I had catastrophic engine failure at 86k miles. Was getting off a highway on an off ramp and got a low oil pressure warning and lose of power/no throttle response from the truck. Pulled over and oil was spewing out. Had it towed to a shop and they said the engine was seized up and there was metal in the oil, recommended full engine replacement.
