Selected complaints filed with NHTSA by 2003 Dodge Ram 1500 owners, lightly cleaned up (personal details are redacted by NHTSA).
Around midday of November 25, 2021, a clear day with no precipitation, while operating the 2003 Dodge Ram 1500 with about 155k miles on it at approximately 35 MPH, the drive train locked up causing the vehicle to go into a skid and a spin that sent the vehicle into a telephone pole. We could have slid into oncoming traffic, fortunately, we did not. The vehicle was totaled. While loading the vehicle onto the tow truck, responders noted that the axle was sheared at the back due to the rear differential locking up unexpectedly. There was a noise, like a whistle or a whine for a few minutes leading up the incident, but not anything that I would associate with this kind or failure, no grinding, roughness, or clunking.
The contact owns a 2003 Dodge Ram 1500. The contact stated that while driving at slow speeds, the driveshaft detached. Due to the failure, the gear oil and rear differential fluid leaked out of the vehicle. The contact was able to temporarily repair the driveshaft. The dealer and the manufacturer were notified of the failure but offered no assistance. Additionally, the VIN was included in NHTSA Campaign Number: 15V312000 (Air Bags) however, the contact was informed that due to a crack in the dashboard, he would be charged for the repair. The vehicle was not repaired. The failure mileage was approximately 230,000.
The driveshaft to pinion gear at the differential comes loose during normal driving. I have replaced the bit numerous times, but it keeps coming loose. There is a recall on same truck but different years. The exact problem the other Rams have is exact issue with mine. When it comes loose, the car grinds to a halt.
Rear end of my ram 1500 pickup model year 2003 locked up doing 60 MPH on the interstate broke the drive shaft and the front of the rear end and yoke off. This is the third rear end I have put in this truck. This has been reported all over the internet thousands and thousands of times over about these Dodge ram 1500 pickup truck rear ends having catastrophic failure causing injury and near fatalities yet Chrysler Dodge Jeep still has not issued a recall for the 2003 model year ram 1500 rear end. It is the same exact rear end as the model year 2005 which has the same recall and other years that they have issued recalls for. I cannot understand how this has gone on for years with so many reports and incidences of this happening and still nothing being done of it. Again this is the third rear end I have put in my truck. …
While driving on the expressway at approximately 60 MPH the rear axle pinion bolt vibrated off, causing the driveshaft to drop from the rear, the wheels locked up and the truck swerved to the left, luckily it swerved into a grassy median and not into another vehicle. The 2005 Dodge Ram was recalled for the same issue, no adhesive on the bolt to stop it from vibrating off. Its the same truck with the same rear and the same problem, and it should also be recalled before someone is killed!
The steering is very loose, when going over a bump the vehicle is pulled into another direction and you temporarily lose control of the vehicle. The 4x4 was not operating properly, so the transfer case was replaced. Upon replacing transfer case the rear differential locked up and the rear wheels won't move. This seems to be a very common issue with this vehicle. All of these issues are common among Dodge Ram 1500s of this year( 2003) these issues should be recalled!
I brought my truck in for a routine transmission service, and alerted the service guy about a loud growling noise coming from the trans/ rear end. This had been becoming more frequent and louder every time I took my foot off the gas, upon deceleration. After inspection, it was discovered that the pinion nut was coming off. This caused a lot of damage inside the differential. After learning this, I was frustrated and researched online to see if there was a recall, there is a recall for the 2005 model year, but mine is a 2003... But it's the exact same problem! I can't be the only one who's had this happen in this model year, mine and my families lives could've been in jeopardy! …
While driving down the road I felt my entire truck shudder. Pulled over as soon as possible and saw driveshaft laying on the ground. Had truck towed back to my residence, where I inspected threat end and saw that the pinion but had backed off and cause driveshaft to come undone from rear differential my entire rear end is locked up and needs to be rebuilt. There is currently a recall for 2004 and 2005 for this same issue. However the recall states this could happen. Unfortunately it did happen to me and currently my vehicle is not on the list. 2003 Ram 1500 has 9.25 rear end, same as the recalled vehicles. I've been told by Chrysler that I should get vehicle repaired and hold onto receipt in case a recall arises with my vehicle. …
While driving the vehicle on a flat, paved road a sudden small grinding noise was detected. Without warning, the rear axle froze and the rear wheels locked up. As the vehicle slid to a stop, a loud noise was heard. After the vehicle stopped moving a quick visual inspection revealed that the drive shaft had broken off and was hanging down. A large amount of viscous fluid was spilled on the road. The truck was not able to move forward or backward at this point due to the locking of the rear wheels and lack of a functioning drive shaft. The vehicle was on a blind curve on a well traveled road and the police were called. It was necessary for the officer to remain and direct traffic around the vehicle due to the dangerous situation. The vehicle was towed to a local Dodge dealer and a claim (# 32479801) was filed via the Dodge customer care hotline.
Dodge Ram 1500 was brought into local 5 star dealer and repaired 3 times prior to the accident for 4-wheel drive "popping out of gear". Vehicle was parked, 3 hours later rolled back and hit a building with significant damage to the left rear quarter panel, undercarriage, possibly frame and right and rear bumper. Vehicle was found in park, documented in police report as being found in park. Brought into same 5star dealer who let it sit on the lot, never looked at it. I initiated an investigation via Chrysler. An investigator came out, looked at the transfer case with a flashlight, never put the vehicle in four wheel drive, and left. We now own a wrecked vehicle with a defective transfer case and nobody will repair it. We have 17K on this engine and all components are supposedly on a full and extended warranty. Chrysler will do nothing!!!!
