The dangerous behavior occurs only when the truck is in four-wheel-drive. Two behaviors: One:Low range. Ascending up a steep dirt road without warning truck shifted into neutral and got stuck there. Shifting into reverse drive or park did not take it out of neutral. The steering and brakes worked. The four-wheel-drive, low and four-wheel-drive high indicatorlights were blinking simultaneously. This behavior persisted after turning the truck off and on again. I had to back down a switchback dirt road. Eventually, I thought to disconnect the battery and reconnect it which corrected the behavior and put the truck back to normal. I no longer use this truck in four-wheel-drive low. I am having the truck looked at by a second dealer service department to try to diagnose this problem. 2: the second abnormal, behavior occurs in four-wheel-drive low, first gear heading downhill using the engine compression for braking. The truck will without warning shift into 2 Wheel Dr. high range, and the four-wheel-drive, low and four-wheel-drive high indicator lights blink simultaneously. This behavior is corrected by turning the engine off and then on again.

I brought my truck in because the check engine light was on. My mechanic first replaced the oil pressure sensor, but the check engine light came back on. The oil pressure is low, and the oil pump is the problem. I only have 62,000 miles on the truck, and have kept up with oil changes and maintenance.

The engine light came on, and I noticed some noise under the hood at the same time. The actual code for the OBD two diagnostics was poa43. Drive motor a position sensor circuit issue. It appears that the Rams have a E torque system that is failing over and over again its federal warranty is eight years and 80,000 miles. I am just above the mileage unfortunately it’ll have to pay thousands probably. This really shouldn’t fail on a vehicle like this and hundreds of people have it and the part is backordered so you have downtime of your vehicle for weeks if not months.

Rear window seal has allowed water in to the cab of the truck and the electronic components under the back seat have already had to be replaced causing the vehicle to not operate properly. The rear window is still leaking and has leaked since 2021, when it was replaced under warranty. If water enters into the electronic components under the back seat or the air bags located in the head liner, while driving, this could cause severe damage to property and could be harmful to life.

As we were driving and pulling a 32 foot trailer battery died, luckily we were able to stop safety and charge battery and bought a new battery to get us home. The Mopar 48‑volt motor‑generator unit (MGU)—often referred to as the “eTorque alternator died. There is a back order of currently 4800+ and months to get this part in order to fix a truck that doesn’t start without it. How is this not a recall? This is highly unsafe if we hadn’t been watching the battery voltage as we were driving and noticed it was getting dangerously low potentially causing a huge pile up accident on the freeway with our trailer.

E torque alternator generator failure, loss of power while driving to all vehicle electrical systems. Part is on national backorder. Reading forums this has been an issue with ram on failure and backorder issues for over a year.

Electrical System
Filed Jun 26, 2025KY

The alternator failed suddenly and without warning, leaving me stranded on a road with no shoulder during 91°F heat. The vehicle lost electrical power and required a tow. This is not just a standard alternator,it’s a component of the eTorque mild hybrid system and requires both a specific part and a dealer reprogramming (flash) to function. After the incident, I learned that the part is on national backorder with more than 4,000 vehicles waiting, according to multiple dealers and service centers I’ve contacted. Ram has provided no reliable ETA, loaner, or support option. This is a critical failure that completely disables the vehicle and creates a dangerous safety situation, especially in high temperatures or in areas where pulling over safely is not an option. I was without air conditioning or any form of engine power while exposed to traffic and heat, and had to wait a prolonged time for a tow. This appears to be a widespread issue with Ram eTorque vehicles, particularly the alternator/starter-generator assembly. The required flash must be performed by a dealer, so no aftermarket or independent fix is currently viable. Ram has not issued a recall or taken accountability for this dangerous and increasingly common failure. I am filing this report to request investigation into the failure rate of these eTorque alternators, the supply chain delays that make timely repairs impossible, and the complete lack of contingency support or guidance for affected customers.

Engine failure with no warning — cylinder #7 collapsed, pushrod broke, and exhaust manifold cracked at only 68,000 miles. This is a known issue with 5.7L HEMI engines, particularly involving defective lifters and camshafts. These failures can result in total engine loss, potential stalling at speed, or permanent engine damage. I am reporting this due to concern over the growing number of similar failures in Ram trucks with low mileage, which may indicate a design defect. FCA/Stellantis has denied goodwill assistance despite low mileage and well-documented cases. This could be a safety issue if engine failure occurs while driving. Please investigate.

2019 ram 1500 big horn rear back lite leak. Anytime it rains it pours from the frame where it has developed two cracks on either side of the power sliding window. Dealer states it needs replaced after resealing the window and the 3rd brake light. Dealer states Ram will not pay for the replacement even though there is an extended warranty for 8 years or 150k miles on the backlite. I have opened a case with customer care...all they do is mediate between you and dealer they have no access to TSB bulletins or service records. TSB bulletin located on NHSTA site states replacement. Dealer states they only reseal and that the one I can see is outdated. Dealer wrote on last service record that the backlite needs replaced. Note: there is a electronic hub located behind the seats. Also, potential mold growth as the vehicle has a persistent musty smell.

I was driving my truck down the road and the power steering went out. I pulled over in a parking lot and turned the truck off. I waited about 5 minutes and restarted the truck; the power steering came back. I proceeded to head home, and the power steering locked up and the truck would not turn at all. I was in a residential area and was able to stop as far right on the road as I could. I again turned the truck off and waited about 5 minutes and restarted the truck. The power steering worked for me to get the truck home. I took the truck to a Dodge dealership and was quoted $4100 for parts and labor. I feel that the research that I have done warrants the dealership to repair the truck. There are safety recalls for my make, year, and model, just not my Vin.

- I like to report that my Ram 1500 Classic has been having issues with steering since March 2025. I had around at that time 78k miles on the truck give or take. I took the truck to the dealership where I purchased it (Brown Daub Easton PA). They claimed that everything I told them about the Truck was perfectly fine and they had multiple people test drive the truck with no issues. I explained that the steering would be very hard to execute a turn left or right and at times it would even feel like it "skipped" in the steering. I can tell I have slightly new wheels at the time of this issue. The only thing they noted was my rear passenger tire tread was a little more worn compared to the other three. I took the Truck home very disappointed and the problem actually seem like it went away for a few days. Then the problem began to show again and the turning aspect is becoming more difficult. Recently while driving on the interstate my steering was affected just changing lanes at 65 mph where the need to use both hands was troublesome. The truck itself had jolt where I never encountered. - - I believe that driving this truck is very dangerous and taken it to the dealership where I have a warranty appears to be impossible to identify the root issue. - I have only taken it to the dealership once and its scheduled to go back to the home dealership on the 12th of this month for another check. -There are no warning lamps/messages.

I just got off the highway where I was driving 65mph. I was drive down the road with a passenger making a right hand turn. In the middle of the turn the power steering stopped working and I proceeded to go straight. I was able to stop before crashing into a wall. I couldn’t only imagine the pannic of losing power steering at 65mph on a high way. The dealer said I need a $3,000 rack and Pinion. All over the internet it shows the 2019 ram was built with a faulty power steering and a lot were recalled. I don’t see how the recall didn’t make it to my vehicle but it almost caused a huge accident.

While changing the oil in my truck I noticed that the oil pan was severely corroded, I mean badly. I looked around under the rest of the truck and there really wasn't any corrosion anywhere else that I could see. I looked online and found out that this is a huge issue with these types of vehicles and the corrosion will get so bad that the vehicle will weep oil which puts the engine at risk but is also horrible for the environment. I took the truck to the dealership and the service manager explained to me that they are well aware of the problem but Ram refuses to do anything about it and claims it's caused by environmental factors. Funny how those environmental factors only affect the oil pan and nothing else on the truck. As I stated, this is a huge potential issue for the environment because Ram is well aware of this but refuses to address it.

My 2019 RAM 1500 Big Horn/Longhorn 3.6L V6 (VIN: [XXX] ) experienced a sudden and catastrophic engine failure without warning while driving. The vehicle shut off unexpectedly on the highway and would not restart. There were no prior dashboard warning lights, low oil pressure indicators, or error messages before the incident. A full diagnostic revealed severe mechanical failure in cylinder 1, including piston-to-valve contact and 40% leak-down with compression at 50 psi. This damage rendered the engine inoperable and required a complete replacement. Prior to the failure: The vehicle was regularly maintained using synthetic oil, following the manufacturer's recommended intervals (between 6,500–10,000 miles). The oil life indicator was followed, and the truck was never low on oil or pressure. A Customer Satisfaction Notification for PCM (Powertrain Control Module) reprogramming was never completed due to the dealer’s system being down on two separate service visits. Despite following proper maintenance and attempting to comply with the manufacturer’s recall-like notice, the engine failure occurred without any warning or indication. The dealership and warranty provider have attempted to deny responsibility, blaming maintenance intervals without proof that it caused the failure. This is a serious safety concern as the engine shut down at highway speed, placing me and others at risk.

What component or system failed or malfunctioned, and is it available for inspection upon request? -The issue involved the truck’s parking and collision avoidance systems, which suddenly shut off. A warning message appeared on the dashboard stating "Service Shifter." This issue may be related to the electronic shifter module or associated control systems. The vehicle is currently available for inspection upon request. How was your safety or the safety of others put at risk? -The sudden deactivation of both the parking and collision systems while the vehicle was in motion created a serious safety hazard. Without collision avoidance functionality and the ability to securely park the vehicle, there was increased risk of unintentional vehicle movement or inability to avoid obstacles, which could have led to a crash or injury. Has the problem been reproduced or confirmed by a dealer or independent service center? -Yes, the truck was taken to an authorized dealer for assessment, and the issue was confirmed. Diagnostic tests found trouble codes starting with "U", which typically indicate a communication or control module fault within the vehicle’s network. The codes provided from the dealer are U0159, U0140, U0100, U0137, U0102, U10121, and U0101. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? -The issue has been inspected and documented by the dealership.

Driving 60mph in 8th gear while raining, 40 deg F, in Minnesota. The truck shut off (I did not press the Start/Stop button) and dash said "Vehicle Not in Park." Went to pull over, put on turn signals, but they didn't work (it acted like the vehicle was completely shut off but was still rolling at 50+ mph in 8th gear - there was no indication on the dash that showed green light indicating turn signal was working). I suspect brake lights also did not work at this time, but cannot confirm because I couldn't see them. I pulled over to shoulder, slowed to a stop, and put vehicle into Park manually. Pressed Stop/Start button and vehicle started. No codes were thrown. Drove another 2-3 miles and similar issue happened again.

I took my truck into my mechanic for a loud whining noise coming from my engine bay. I was told my alternator is going out. I have a 2019 ram 1500 5.7L v8 with the e-torque system. Part number 68438054AB or 68623194AB. This part you can literally buy from no one. Not a dodge dealership, mopar or any other website. There is about 1 listing I saw for a used one which was $1000 over what a new one would cost. If this part goes out I’m fully unable to use my truck which has 56,000 miles and is my only means of transportation. I have absolutely no chance of buying this part from anyone or anywhere at this current time. I can barely afford to buy the part even if it was available and I surely can’t afford to pay for a rental car or another car in the time it would take for this part to become available (if it does). From reading online and hearing what the Dodge dealership told me there is about 4,000+ people waiting for this same part. I still am paying a loan for this truck and I am at a loss on what to do.
