ABS light keeps coming on and off. The 4WD keeps going on and off and the cruise control and traction keeps working then not working. There is a recall for other year models for the ABS system that basically is exactly what’s happening with my truck. I am worried that it will go out and my truck will stop and cause and accident which almost happened today. This should be a recall alongside those other year models.

My truck was taken to the ram dealership in Conway, AR and they told me it needed an ABS Module and it was ordered and that was in January of 2025 so it has now been almost a year that the part (ABS Module) has been on back order and there is still no ETA. That is a serious issue and my truck that I have still been paying on is not fit to drive safely and hasn’t been since. Something needs to be done about that and time is very much of the essence!

ABS module needs replaced. It was recalled in all trucks except for this year model. It is currently on back order and I have been waiting for the part for almost a year! All emergency lights in the dash are on all the time and now when I am driving, the accelerator goes completely dead. It happens randomly and has happened multiple times now. The dealership has accessed this and stated that the ABS module will fix the problem. This is very dangerous and needs to be looked into. Why can’t they fix my truck?

This is the second time this has happened (03APR25). The first time this occurred, 20JUL25, I had to pay (Bill attached) to have the ABS Module replaced. Today several service lights came on not limited to: Service 4wd, 4wd Trans Case overheat, stabilization system, and the traction control light came on along with the 4wd High light and both the 4wd High and 4wd Low indicator lights were all flashing. When parked the emergency parking brake was automatically set. (break) I have all the documentation from the first occurrence and an additional recall notice (Attached) of which states contact the dealer, whom said that it was not their responsibility. Then I contacted Stellantis recall office, and they said they would get back with me and never have and today most all the sensor faults flashed on the display. The truck locked in 4 high up until I parked it.

Installed trailer brake assist. When we shut the truck off, the brake lights came on and stayed on. Assured by B&B trailer of St Augustine, Fl that it was an issue with the truck and not the part. Other issues have come up- dash lights also come on when turned off, backup camera, remote start, rear defrost, cig lighter plug, rear speakers, and A/C stopped working. Took it to Daytona Dodge on 1/29/25 where they diagnosed the ABS module had failed. They did a system reset and everything was ok until we had to disconnect the battery again- had to install a switch on the battery so lights staying on doesn’t kill the battery. Was told they’d let us know when a new part came in- mid February. Called Ram HQ on 2/17- case # [XXX] and that was no help. Referenced recall 85B and she said it was for a 2d row seating issue and said no ETA on new parts being made. My truck was mfg 2/2020 so how the software update recall doesn’t apply makes no sense. Would it have prevented this, who knows. Then called the dealer up and spoke to Stephen, a svc mgr, who recommended buying a used one ( he said aftermarket but I don’t think there is such a thing) and they would put it in. Got one from eBay and went on [XXX]. After I sat there all morning, I was told they couldn’t override the Vin that’s already on a used part. I have tried calling and emailing the service management team for follow up since then with no response. This is an abomination of customer care and needs attention. I’m hoping these parts are coming soon and that people like me are reimbursed and compensated for time lost and diagnostic fees and parts and labor. Also hoping this recall is expanded/redone to include my truck as there’s no reason it shouldn’t. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
