The contact owned a 2015 Ram 1500. The contact stated that while hauling a 2018 Jayco Hummingbird at 50 MPH, the "Low Voltage Battery" warning message appeared on the instrument panel. The contact immediately pulled over and exited the vehicle as white smoke began to emit from underneath the hood. The smoke quickly turned into flames as the contact attempted to extinguish the fire with a fire extinguisher. The contact used a total of three fire extinguishers in an attempt to extinguish the fire; however, the fire returned after each attempt. With the assistance of a fellow motorist, the contact managed to pour water over the entire engine which finally extinguished the fire. The authorities arrived at the scene and performed a thorough inspection of the vehicle to ensure that the fire was extinguished. A police report was filed. The contact suffered severe mental trauma as a result of the incident. The vehicle was initially towed to an independent tow yard but was later placed in the possession of the contact's insurance company. The dealer nor the manufacturer had yet to be notified of the failure. The vehicle was deemed a total loss as a result of the fire. The failure mileage was approximately 122,000.

I previously sent a complaint regarding my vehicles CRANKSHAFT POSITION SENSOR. I took it to a dealership and I now have to wait for the part to be ordered! Then it is going to be about 2 weeks before it can be repaired! I was told by the dealership that this part had been on a recall list! So I feel someone should be responsible for fixing and paying for this repair! Approximately $1000! I bought the truck used so therefore the dealer I bought it from should have known this! Right?! HOLZHAUERS MOTORS..NASHVILLE ILLINOIS My truck is being repaired by ABSHER ARNOLD MOTORS MARION ILLINOIS NOW. This is close to where I now live. I really feel someone should be helping me with this repair! You can verify my info by contacting Absher Motors 618-993-5000 Help would be appreciated!

My Ram 1500 Ecodiesel was reprogrammed by Henkle Auto dealership in Battle Creek Mi. It now has a dead fuel pedal when cold and will then lunge all at once. I also lost 4 mpg. I have contacted the dealer and Ram Chrysler, and they said that there is nothing they can do to undue an updated ECM program. My case number from Chrysler is [XXX]. This is a huge safety issue, and the dealer or Chrysler will fix the issue. Need help. Thank You INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Dodge sent us a safety recall in May 2021 for Crankshaft Positioner Sensor and Toner Wheel faulty part. We took it to our local dodge dealership, they ran a computer test and said "it's fine" and sent us on our way. The car involuntarily stalled a few times while driving it the past few years. In February 2024, we took the vehicle in (AGAIN) to have the same issue looked at and they said the part needed to be replaced and said dodge will not pay for it and charged us $2900. Dodge is refusing to take accountability for this original safety recall and we are very concerned that our family was put at risk many times while driving this vehicle. Dodge new this part was a faulty part and refused to replace it.

The engine seems to have failed. Yes it is available for inspection upon request. My safety was put at risk as the vehicle lost all power on the highway. Yes, the problem has been confirmed by a dealer or independent service center. Yes, the vehicle has been inspected, but due diligence needs to be done on the part of the inspectors to get at the root cause of the failure. No, that was one of the most alarming and scary parts is that there were no symptoms, warning messages, etc.

Vehicle would not restart after being shut off, thereby leaving me stranded on the side of the road in an area without cell phone reception or through-traffic, which led to me having to walk 7 miles at night while in below-freezing temperatures to get help. The engine component that failed was the tone wheel (part of the crank position sensing system). It failed without any warning. This engine component was previously subject to a recall (W58) that did not address the primary issue, which is the component's manufacturing/design defect that renders the vehicle inoperable as soon as it occurs. This defect can create life-threatening situations for drivers and passengers inside these vehicles when the defect occurs in uninhabited areas, as well as other motorists if the defect occurs on busy roadways. Many others have reported experiencing the same problem in vehicles with relatively low mileage, which is unique to this particular engine.

My Ram 1500 has lost power several times while cruising at 55+. The first time was related to recall W58. My crank sensor became delaminated and caused my truck to completely die. After months of waiting I finally received my truck back, however, the recall is still open due to there being no fix. Just a few months later my truck died twice on the highway. This time it was due to recall Z46. After being sent from one person to the next all I am left with is I am on a list that is about 2 years behind for replacement parts.

Good morning! I own a 2015 Ram Ecodiesel. I am not the original owner. I am in California. The truck is not under warranty and the FCC will not help me nor the dealership. A few months ago I was towing my horses in a trailer and the truck started to lose acceleration, started to over heat, black smoke was coming out from under the hood, and it almost lost power going up a hill. It was very scary and it almost caused an accident and my horses were terrified. I barely got it to drive up the hill and pulled over to safe place. The truck was smoking black smoke, smelled terrible, and we felt in danger. I took truck to dealership in San Luis Obispo CA. It was diagnosed with a bad intake manifold, bad fuel lines, bad egr cooler. The estimate in costs was about $7,000. Luckily my husband is a mechanic and he performed the repairs. Than the truck was back up and running, no more black smoke, and it sounded better. On [XXX] I was hauling my horses and small only 2 horse trailer, same trailer, it-??s small, not oversized or too big for my truck-??.. the truck started to lag, lose acceleration and drive slow, then it started a knocking sound-??.. then a high pitch noise-??.. this was terrifying as we were on a very busy freeway. I pulled over and the engine started to smoke and make horrible noises like knocking and high pitch screeches. My husband and I and our two horses were once again stranded with a broken down truck. This time on a very busy freeway, highway [XXX] in California. The truck was towed to the dealership that day. We were stranded for hours with horses and no water on side of a freeway. The truck was diagnosed by Santa maria, CA dodge ram Chrysler with a blown up engine, that must be completely replaced. The repair is $20,000 or more. This is a common issue in these trucks. This truck is dangerous and needs to be recalled and taken off the road. All of these engines are bad and they should all be bought back. They were ruined after the emissions scandal.

The contact owns a 2015 Ram 1500. The contact stated while driving approximately 20 MPH and making a right turn, the vehicle jerked twice. There was white smoke coming from under the hood. The smoke was thick and obstructed the driver-??s view before the vehicle stalled. There were no warning lights illuminated. The vehicle was towed to the local dealer, where it was diagnosed that the rod bearing had become inoperable, and an engine replacement was needed. The vehicle was not repaired. The manufacturer was contacted, and the contact was referred to the NHTSA Hotline, but no assistance was provided. The failure mileage was approximately 109,000.

My truck is experiencing the -??hemi tick-??. Upon research, this tick is a common defect in RAM trucks that was supposed to be fixed in later models. Not true. Not only do I need to pay thousands for replacing the manifold, it will be a problem again. The hot/cold engine melds the aluminum and steel, creating a warped or split manifold. To replace it is immense labor, hence costly fees, as the bolts are too small to adequately remove and snap. If drilling out, metal could get into other parts of the engine causing severe damage. I bought this used at $30,000 miles (approx). Per my mechanic, the manifold has already been altered once. They claim it-??s a safety concern, which includes -??loss of power -?? especially at highway speeds. This is in addition to the repair costa and loss of value. The earliest appointment is a month away. Yes, it could be inspected upon request. It has been inspected by Arbos and G&D auto repair. Both whom are unable to remove the bolts and referred me to a dealership. I have an appointment with Hights Chrysler in Madison, Maine on Nov. 30th. The quotes I have received range from $500 to $2,000. The -??warning-?? is the ticking sound during idle.

5.7L Hemi MDS lifter failure on a vehicle that has less than 96K miles. this is regarding the MDS system lifter and the cam shaft lobe slowly getting wore away until something fails. still available for inspection, i have not attempted to rebuild that cylinderhead bank yet. camshaft/lifter/valve failure at highway speeds could make the vehicle stall and potentially lose control if engine fully seizes or creates drag to the drive terrain. Dealership claims that the "tick" which is horrifically loud inside the passenger cabin on startup and less loud once the oil warms up. is "normal" for these trucks. I am planning on having a 3rd party mechanic give a second opinion before paying to have the engine rebuilt no warning lamps yet, I stopped using the vehicle after it was determined that the tick was indicative of engine failure on most Stellaris 5.7L hemis (challenger, ram 1500, etc.)

Check engine light came on While driving up hill and shortly after I lost all throttle response and cruise control was disengaged. Vehicle started to slow and began to be sluggish. Still no throttle response. Pulled over. Put vehicle in park and then drive. Drove for next 2 hours with no issue. Checked with dealership and truck is throwing codes p066d and P0523. Truck has been fine so nice issue but still throwing those codes.

The vehicle has experienced multiple Turbo underboost code causing the vehicle to be put into limp mode without any explanation, Rhyme or Reason. The vehicle once this code is tripped places the vehicle into limp mode at which time virtually all power is lost this is now happened three different times with no explanation completely randomly the last time was when pulling a trailer uphill resulting in a near crash experience and being stranded on the side of the highway I had to force reset the computer by cycling the ignition to get the code to go away there was no problems prior to this code popping up or after. When this occurs it can be extremely dangerous when at highway speeds considering that the vehicle goes into limp mode and you're no longer able to go more than 10 miles an hour let alone if you're pulling a trailer it's virtually impossible to move the vehicle and if you're going uphill on a two-lane Highway with fully loaded 18 wheelers behind you at 65 mph and you all of a sudden come to a crawl you can see how this poses a major risk for injury or accident

The exhaust manifolds have cracked. This can lead to dangerous fumes getting into cab and extra pollutants to the atmosphere. It can also cause premature engine failure which could be deadly if it happens while driving. This is a known defect with this engine. Thank you

The vehicle loss power why I was attempting to accelerate on the highway. I observed ticking noise from the engine that progressively got louder and began knocking noise that eventually caused the vehicle to under perform. I took vehicle to dealer and they informed me of a damaged lifter in cylinder #5 the damaged cylinder camshaft.
