Failure of the tone wheel on a 2015 Ram 1500 Ecodiesel. W58 recall dated 2/2021 was performed. ( a software repair for a mechanical issue) W68 recall also dated 2/2021 refers to the replacement of the tone wheel in certain Ram 1500 trucks. On 2/26/2024 My vehicle would not start following a lack Of acceleration/hesitation the night before on the freeway with my daughter driving late at night by herself! I Had to have the high pressure fuel system, fuel rails and injectors replaced due to metal shavings found. (All under a separate recall that had just come out) The dealer also said the tone wheel needed replacement and was the source of the inability to start and the hesitation in acceleration that was encountered. Ram refuses to cover the tone wheel despite the knowledge they have regarding the delaminating of the tone wheel. Supposedly the W58, a software update) was to over ride the mechanical issue of a delaminating tone wheel. How can a software update repair an obvious and known mechanical issue? Why was my vehicle given a “band-aide” and not repaired correctly? Why is the NHTSB allowing Ram to band-aide a mechanical issue that could cause serious injuries due to loss of power or acceleration in a traffic scenario. It makes absolutely no sense. Please look at this issue regarding the band-aide fix and enforce the correct decision in W68 to replace the defective mechanical part of ALL affected vehicles allowing the many many owners that have suffered financially due to their ineptitude in fixing the problem correctly the first time! I have been in contact with several people representing RAM with no satisfaction. While various service people sympathize with me and completely understand my point, they are unable to cover the tone wheel repair. It is Very frustrating to deal with customer reps from RAM outside of the dealership who have zero mechanical knowledge.

The HPFP failed 9/15/23 in my ecodiesel traveling down the freeway in three lane traffic. I lost all acceleration , power. no brakes or power steering, I was nearly killed by several semi's because I lost all speed. It nearly caused a massive accident potentially killing me and several others in the process. I had seconds to react it left me traumatized from the event. I had to call a tow truck- which cost me $300- They left me stranded at the dealership in a different state hours from home with nothing. I was without my truck for a week. It was then taken back to my homestate and taken to a local dealership- in which they had it for a few weeks and said it was a dirty radiator filter charging $240 . I had my truck back for 4 days before it started doing the same exact thing and had to be taken back to the dealership. They then admitted it was the recall after all and said I was not allowed to remove it off the property but there was no fix. I was not given a loaner vehicle- I was not helped in any way- My truck is my own vehicle- Im a single female that commuted back and forth to work an hour away from home. They had my truck for 13 weeks- in which they said they did a work around - within 5 minutes of taking it- lost acceleration again, hesitating, multiple issues. Tried to get it back to the dealership- drove it a few times and again multiple issues- hesitations, no acceleration. Was in route to take it back to another diesel mechanic and it completely died and had to have it towed again which was another $500. The next day they said they couldn't fix it and it had to be put on a trailer and taken back over to the other dealership. They DID NOT FIX THE ISSUE!!!! They keep charging all this money- and my truck is still unsafe!!! I lost my job because of it. I have received zero help and absolutely no compensation. That truck is going to kill me or someone else in the process.

My power steering has suddenly became very stiff when turning left or right and the suddenly loosens up causing the truck to quickly shift left or right. It is every turn into a road or stop sign and there’s hesitation or a glitchy jerky feeling around curves going normal speed limit. There were no warning signals lights or errors before during or after the incident.

Aem update caused vehicle to perform in an unsafe manner. Hesitates upon acceleration from stop. Transmission shifts irregular and no longer slows vehicle downhill. During acceleration motor can redline and cause a rapid deceleration. Never sure exactly what is going to happen when pressing the fuel pedal. Never sure if it will safely go when it is supposed to. Fuel economy is also reduced from 28 mpg to 25 mpg. It is now a scary vehicle to drive. Was in right lane eastbound on highway 152 going over pacheo pass behind slow truck traffic at approximately 30 MPH. When attempting to accelerate while changing lanes the motor went to redline and depowered. I quickly had to brake and get back in the right lane behind the truck traffic. The vehicle had never done anything like that in the 4-1/2 years prior to the aem. They ruined my truck with the modifications, it is a major safety issue when the truck shuts off power when accelerating.

After having the required fca emission update, the truck will hesitate when pulling into traffic or attempting to climb a hill until fully warmed up. Pressing the accelerator to the floor does nothing for several seconds, then the truck accelerates dramatically. This nothing/everything, is dangerous to the driver and passengers of the truck as they may be struck by another vehicle that they are not able to get out of the way of. The truck is dangerous to other highway users as the nothing/everything throttle may cause a loss of control of the truck. This is a drastic change in the driving characteristics of this truck from the prior to flash settings. Apparently dealers can not return the vehicle to it's previous settings, making them liable for the safety of the trucks driver and passengers. The epa lawsuit against fca has put numerous highway users ar risk!
