“I took my truck in to get the front end looked at and this local garage inspects the vehicle. They informed me the gas tank brackets and straps have corroded so bad that the gas tank is sagging and how serious it would be if it fell more or fell off completely. Obviously the gas tank falling off and possible exploding or catching fire is a serious safety issue. Upon my own research, there is a safety recall (U04) that did not include my specific truck for unknown reasons. Then upon further digging I found a safety warranty extension (X75) attached to my vehicle. When I took it in to get inspected and fixed, the dealership informed me this is a Canadian truck and they could not fix it under this X75 warranty extension. This truck was built in [XXX] and I purchased it used in [XXX] so I am not sure why the Canadian part has anything to do with this truck. The warranty extension letter even states unlimited miles and it doesn't matter if I am the original owner or not.”

“It appears to be a fuel leak. The incident happened less than 200 miles after having a dealer perform the NHTSA recall 22V-406, FCA recall Z46. The truck caught fire while pulling a travel trailer. The only way we were aware of it was a passing motorist saw flames shooting out from under the right side. As soon as we pulled over the truck immediately filled with smoke and the fire spread as the fuel puddled below the truck. Chrysler sent an inspector to look at the truck, not enough of the engine, passenger cabin, or front of the truck was left to make a conclusive cause. There was no indication we had an issue and if not for the fortunate timing of the passing motorist this could have turned out much worse. I was relating this story in a restaurant to my nephew when a passing waiter asked if it was a ECO diesel and I said yes, he related his story which was identical including the recall. I attempted to put out the fire with a fire extinguisher we kept in the truck but it was too big by the time we pulled over. We were traveling at less than 50MPH stop and go traffic which had just started moving.”

“I am writing to request your assistance regarding my 2016 Ram 1500 EcoDiesel and the handling of a safety-related recall repair that has not resolved the original issue. My vehicle has been experiencing the following symptoms: •Check engine light •Hard starting •Engine struggling to start •Engine stalling These symptoms prompted me to bring the vehicle to an authorized Ram dealership for diagnosis and repair. The dealership informed me that the vehicle qualified for Recall Z46, and the recall was subsequently performed. Unfortunately, after the recall was listed as completed, the vehicle continues to exhibit the exact same symptoms that existed prior to the repair. The check engine light remains, the vehicle still struggles to start, and it continues to stall. After further research I discovered that the entire recall was not completed based on the procedures listed on the NHTSA website. This is extremely concerning because these symptoms create a potential safety risk, particularly when the engine stalls unexpectedly. I have attempted to work through Ram Customer Care to resolve this matter. My experience has been disappointing. I have been unable to obtain…”

“The vehicle was previously repaired under Recall Z46, but the replacement remedy pump suffered the exact same catastrophic internal failure. The vehicle has now been stranded at Orange Coast Ram for over 30 days under Work Order 156725. RAM Corporate Case Management (Case 96867451) is actively refusing to authorize the subsequent recall repair, explicitly stating in writing that corporate has 'no internal channels to obtain approvals,' effectively denying the legally mandated federal safety remedy.”

“The fuel sensor on the truck has been in a failure place for years. It has a full tank, but it keeps reflecting zero gas and it doesn’t wanna pass emissions either it really is a poorly constructive fuel system. It makes you concerned and makes the Buyer spend an extreme amount of money to repair a flimsy piece of plastic. I don’t know why this isn’t a recall. I had to have a bunch of things repaired trying to troubleshoot it, but I’ve never paid the full price to repair the fuel sensor. what the actual problem was discovered…”
