    My truck is equipped with a swing gate tailgate. Today I tried to open the tailgate multiple times and it would not open. It would not let down, nor would the swing gate open.

  2. Other or unspecified, Feb 7, 2025

    I have had 2 separate instances where I had my foot on the brake and the accelerator kicked in, the engine revved up and the truck tried to move forward all while I had my foot still pressed down as hard as I could on the brake. Once the engine was not revving any longer, I put the truck in park and sat for a second so I could gather my composure. After I sat for a second and put it back in Drive it didn't do it again. This happened in the same manner both times. It happened once in October 2024 and the 2nd time in January 2025.

  3. Other or unspecified, Feb 3, 2025

    The bolts that connect the two parts of the exhaust pipe, about midway on the truck, sheared off. The truck is a 2021 with only 47,000 miles on. These bolts should not be shearing off like this

  4. Power train, Other or unspecified, Engine, Jan 29, 2025

    I am submitting this report to alert the NHTSA of potential safety violations and undisclosed structural damage, drivetrain modifications, and possible engine replacement regarding my 2021 RAM 1500, which was purchased from Courtesy Chevrolet after being previously owned by Enterprise Rent-A-Car. Unreported Frame Damage & Structural Repairs Multiple inconsistent and unseen frame welds were discovered, indicating prior accident damage and unreported frame repair. Frame welds do not match factory precision welding, suggesting post-factory reinforcement or structural fixes. Undisclosed Transmission Swap from 8-Speed to 6-Speed According to NHTSA records and the vehicle’s VIN, my RAM 1500 was manufactured with an 8-speed transmission. After purchase, I discovered that the 8-speed had been swapped for an older 6-speed transmission (6HP70), which was never disclosed. This creates potential drivability and safety concerns, as the truck’s ECU may not be calibrated for the correct transmission. Possible Undisclosed Engine Swap The engine in my truck has multiple ink and paint markings, which are commonly seen on replacement engines. RFID engine label does not provide a matching serial number, making it difficult to confirm if the engine is original. The casting number on the engine sticker is inconsistent with the vehicle’s model year and VIN (2021), raising concerns that it may be from an older model. Engine mount bolts and wiring appear disturbed, suggesting prior removal and reinstallation. If my truck has an older or higher-mileage engine, this impacts performance, emissions compliance, warranty status, and safety. Lack of Maintenance Records & Vehicle History Transparency

    I just purchased a new truck on Friday and was told on car fax it had a open recall .On 1/20/25 around 0835 I arrived at service entrance and was not greeted or checked in after being told I would be charged a diagnosis fee for a very important safety recall related to ABS . I would like this incident investigated as it jeopardizes my and my family safety . Also told him the truck was under warranty and the wireless charging for phones was not working and got bring it back to where you bought it . I requested his supervisor and he walked away and acted like he was on the phone . This is my only local dodge dealer and now forced to goad hour south to get this fixed . I took a card because service manager never came out to address me as customer this dealership needs looked into .I think I was also discriminated at for being Caucasian as both service techs are Hispanic info email of service manager from card is Location of Dodge dealer . The person that wanted to charge me avoided me asking his name but had long curly hair and younger thug attitude guy . Also was told to leave after like anyone would be upset of a safety recall that are free and being told I would be charged. I’m requesting an investigation into this matter and or pursuing legal action . I know it’s a federal holiday and I have a 3 day weekend but hope this matter can be addressed soon as this is not right . Thank you .

    Recall on vehicle I just bought for a long trip, has no remedy!

  10. Other or unspecified, Visibility/wiper, Sep 25, 2024

    Both of the front driver and passenger side flip down sun visors have broken within one week of each other. Each visor is attached to the ceiling of the cab by a metal arm with a plastic retaining clip. That plastic clip has broken on both visors within one week of each other and my truck only gets very light use. Since the retaining clip is broken both visors fall out of the ceiling and hang in the view of the driver and block the line of sight, which means the driver can not see directly in front forward. I have spoken to the local Dage Ram dealership who sold me the truck as well as the main national Ram customer service and both say the repair is outside of warranty even though its a safety issue and a clear defect so they will not fix the issues without me paying form $550 plus labor for each visor.

  11. Other or unspecified, Forward collision avoidance, Sep 10, 2024

    After changing the battery, my truck was affected by a computer malfunction which caused my ABS, forward collision detection, electronic stability control and other systems to not work and indicate trouble in the dash. I took it to the dealer, and they charged me $205 to reprogram the computer. These are all symptoms of recall 85B, but my VIN is not in the affected list at this time. I believe the list should be expanded and that I should receive a refund from FCA for the repair work that was completed.

    This has happened twice both on the interstate. Vehicle just turns off by itself. No codes are flashed up (unless they came up right as it happened and I didn't see them because I was too worried about getting hit). I called the Dodge dealership and scheduled an appointment. Went on 3/9/2024. They scanned the vehicle and did not see any codes. Was asked if I wanted to have a tech look at the vehicle. Was recommended not to because there was no codes and the likelihood of them finding anything was slim to none. They were also going to charge me for the diagnostic (to have the tech look at it) even if there was not an issue found. Service Rep (not the tech) told me she recommended that I try to take a video of it, if it happens again, so they could see what codes come up. This issue as well as the suggestion to try to video it is a huge safety risk. (happened 1/28/2024 the first time I thought it was because the vehicle sat for a week without being driven - figured it was water in the fuel until it happened again on 3/4/2024)

  15. Other or unspecified, Feb 28, 2024

    Once again this truck turned off on me as I was entering the freeway and this last incident occurred with my kids in tow so I called my financing company to come pick it up cause we almost got hit and it wasn’t gonna be good…but thankful the rig driver was able to move to the next lane and he pulled over and checked on us and gave us video. It sat at the dealership for the first year on and off for this issue and due to it never happening with them they disregarded the issues. Second year again truck in and out the dealership and still since it didn’t happen under their watch again disregard. I have multiple videos and statements but that didn’t make ram fca listen.

    Two Bolts were broken between intermediate pipe and muffler flange. There are 2 more bolts that were not replaced and will probably break and need repair!!!

  17. Structure, Other or unspecified, Jan 6, 2024

    high quantities of water leaking through the rear glass in amounts so great it even soaks the rear floor carpet in water after only a few minutes in the rain from running down the back wall of the cab. Water leaks down the inside of the back window directly onto and over the 48 Volt lithium ion battery pack, equipped in my ram Etorque model. this occurs even after small quantities of rain, after water testing it myself it is clear the water is going between the rear glass and the body and into the cabin. I have had this documented with the dealer twice, and called Ram corporate support multiple times, and receive the same answer, and even though I have a seven year 1,000,000 mile warranty, they refused to fix it stating it is not covered. however the exact same issue has created an extended warranty condition out to 10 years for ram 1500 models built between 2019 until September 30 of 2020. the build date of my vehicle is October 19 of 2020. 20 days later.. Corporate support refuses to believe this condition may have existed beyond their September 30, 2020 date. As it is well documented with the mass quantities of electric vehicle fires, created by lithium ion battery packs, I tried to file a safety complaint as well. The answer I received from Ram corporate was “the lithium ion battery pack beneath the rear window behind the rear seats is a sealed system, so it is OK if it gets wet” even though it is inside of the cab. The ram 1500s from my date range have known issues with water leaks through the rear center mounted brake light and through the glass due to cracked frames on the vehicles, sliding rear windows, such as mine, however they refused to believe any of those conditions may have transferred to my specific vehicle despite a $7000 extended warranty. I am Reporting this condition because I am afraid water intrusion onto a lithium ion battery inside the vehicle could result in loss of life as this system is now a standard feature on all ram 1500s as of 2022.

    While driving (10-18mph), engine suddenly stalls (going from Run into ACC mode on the engine start/stop) and notifies me via dash warning that the vehicle must be put into park and continues to coast forward as if in neutral. I was able to pull over to the side of the road and turn the dial from drive into Park. After a few seconds, I press the engine start/stop button and the engine restarts and i turned the dial to Drive. This may be a problem with the eTorque.

IT IS VERY SMELLY AND I CAN SEE EXACTLY WHERE THE TRUCK IS LEAKING. I UNDERSTAND THERE IS A LAWSUIT GOING ON FOR THIS EXACT PROBLEM. WHAT ARE MY OPTIONS.

    I started smelling coolant inside the cabin of my 2021 RAM 1500 at approximately 49000 miles. I'm the original owner. After waiting for over a month before the dealership could look at my truck, I was told my heater core needed replaced at a cost of $2369.52 and charged a diagnostic fee of $201.49. Because the basic warranty had expired, and the truck is less than 3 years old, I called Chrysler Customer Care for assistance. They opened case number 87011413, and was assigned a case manager. I was told I would be contacted in 1 to 2 business days. It has been 3 weeks, and I still haven't heard from the case manager. I tried calling Customer Care several times but I only get voice mail.

    Has happened a few different times but didn't know what was happening. I'm driving, yesterday was on the highway at 65mph and my truck suddenly "stalls out" for a few seconds! I almost lose control of the vehicle! No power steering no brakes no control and then all of a sudden comes back on. Cars going behind me are driving around me. Scariest thing ever happened while driving. I first noticed it a year ago but was not a interstate wasn't as scary. Then has happened through out the year 4 or 5 more times. The VIN says no recalls but it sounds exactly like the powertrain control module problem. My truck is a hemi 5.7-liter engine that is randomly stalling multiple times now almost causing me to wreck!
