2019 Ram 1500: engine stalls while driving

Filed Oct 26, 2026 · Fuel system · MO

The failed component is the high-pressure fuel pump, which the dealer confirmed failed and contaminated the fuel system. I do not know whether the failed pump will be available for inspection, since the dealer is replacing it. The engine stalled while I was driving on [road type, e.g., a highway] with my family [in the vehicle / traveling with me] and would not restart, which put us at risk of losing power in traffic. The dealer confirmed the failure and opened the recall repair. To my knowledge, the manufacturer has not inspected the truck. The red throttle warning light came on and the truck stored a P016F fuel pressure code at the time of the failure. A MAP sensor code had appeared earlier and cleared, but I'm not aware of other warning signs before the failure.

The manufacturer defect involving stress cracks in the rear window structure (TSB 23-042-24) caused water to flood the rear cab wall along with the leaking rear cab air pressure vents. This water has short-circuited the CAN-bus network/RF Hub, causing active dashboard failures including 'Service Shifter' and 'ParkSense Temporarily Unavailable.' The vehicle is at immediate risk of locking in Park, stalling, or failing to shift while driving, creating an immediate crash hazard. Additionally, the exhaust manifolds are leaking, risking exhaust gas intrusion into the cabin. The dealership, Earnhardt Chrysler Dodge Jeep Ram at 1521 E Drivers Way, Gilbert, AZ 85297, has failed to resolve the water leaks over 4 separate visits this month." I was told a software update fixed the issue. Then at the last visit something electrical was replaced, the issue is still happening. The leaking rear cab air pressure vents have not been addressed in the previous 2 service appointments. This also allows water to leak onto the RF Hub

The vehicle loses power unexpectedly without triggering a MIF indicator or logging a OBDII diagnostic code. The problem is the crankshaft position sensor temporarily fails causing the vehicle to stall, in my case, in stop and go traffic, which caused an accident. Once the 'Heat Soak' effect passes, the vehicle start and drives normally again. The fix, to preventing it from happening again and solving the heat soak problem, is to replace the crankshaft position sensor with an OEM part which is less susceptible to the ambient heat (heat soak) due the proximity to the exhaust manifold. And, to have the software in the PCM 'Flashed' or upgraded to allow for a greater signal tolerance from the crankshaft position sensor. The problem and fix where confirmed by Auto-Nation Chrysler Dodge Jeep RAM, [XXX], where I purchased the OEM part and had their service department 'Flash' the PCM for the software upgrade. The service department and the parts clerk agreed that TSB 18-020-26 applied, dated XXX. Upon further research I discovered a recall report: 18v-049 Part 573 Safety recall report. It is proof FCA US LLC (Manufacturer of my 2019 Dodge RAM 1500 Classic) knew about the problem with the Pentastar 3.6L engine. The same 3.6L engine in the recall. Or, they should have know about the potential problem. Although my vehicle was not part of the 18v-049 recall, it has the same 3.6L engine and exhibited the same engineering shortcomings as the recalled engine? As a concerned citizen I felt compelled to bring the public safety problem to your attention, even though I feel I am not the only one who has complained about the problem. And, because I feel strongly about this, I am planning to file suite in small claim court against the manufacture: FCA US LLC. I would like to update your office with a copy of the filing as soon as I am issued a court date. Thank you for your time and consideration.

The 48-Volt Belt-Driven Hybrid Starter Generator / Motor Generator Unit (MGU / eTorque Alternator) suffered a catastrophic failure on my vehicle at approximately [Insert Mileage, e.g., 140,000] miles. The failure occurred while traveling out of state away from home, causing a sudden loss of vehicle charging, dashboard electrical errors ("Battery Saver Mode"), and creating an imminent threat of an engine stall in live traffic. Due to widespread manufacturer part backorders exceeding tens of thousands of units, my vehicle was forced to sit at a dealership until I could pay thousands of dollars out-of-pocket for a component that Ram has actively removed from newer production vehicles due to its high failure rate. This is a severe, systemic durability and safety issue affecting thousands of trucks. I am requesting that the federal safety agency force FCA/Stellantis to issue a safety recall and establish a retroactive reimbursement program for all owners who paid out-of-pocket for MGU replacements. I possess the official out-of-state dealership invoice and proof of payment.

​SUMMARY OF ISSUE: Water intrusion from a defective factory rear window seal flooded the Radio Frequency (RF) Hub module, causing severe, dangerous network communication (CAN bus) failures while driving. The removed RF Hub has been retained by the owner and is available for physical inspection upon request. SAFETY RISKS: Power steering repeatedly seizes/locks up while driving. ​Vehicle completely stalls and freezes in active intersections and at highway speeds on I-95. ​Instrument panel illuminates with all warning lights ("Christmas tree" dash) and prompts driver to "Put Vehicle in Park and Put Back in Drive" while actively moving in traffic. ​Vehicle experiences complete power loss, creating a severe rear-end collision hazard. ​TIMELINE & MILEAGE: 60,328 mi (Dec 2022): Initial electrical glitches reported to dealer prior to 100k warranty expiration. ​92,733 mi (Sept 2024): Reported ongoing key fob loss, electrical anomalies, and TPMS drops. ​168,492 km (~104,696 mi): Scanned multiple CAN bus "U-codes" (documentation available). ​104,716 mi (Sept 22, 2025): Leaking rear window seal repaired by dealer. ​~114,000 mi: Worsening symptoms and total vehicle stall. ​DEALER FAILURE & DENIAL: When repairing the window seal, the dealer failed to inspect for interior water damage or check underlying electronics. They refused to open/inspect the RF Hub, claimed they could not reproduce the intermittent issue, and are attempting to blame an unrelated "star connector." The owner opened the RF Hub casing and photographed clear galvanic solder corrosion and water damage directly under the leak point. Component has not been inspected by police, insurance, or manufacturer reps. PRIOR SYMPTOMS: Progressive TPMS loss, "Key Fob Not Detected" while driving, throttle surges at stops, parasitic battery drain, and full dash light warnings—worsening with humidity and rain.

When driving the truck the power steering would go out and make the truck almost impossible to turn. This is dangerous when driving as you cannot turn, avoid a collision, etc. I've had vehicles without power steering, and this was like the truck is actively pulling against you when trying to turn. The dealership did a diagnostic and said the power steering rack (electronic) needs to be replaced completely as it's going out. I'm not sure if it's related, but I've had other issues before this where my lane assist and cruise control would flash while in use and all turn off while driving down the road as well. There was no obvious check engine light or codes for this, just the occasional shutting off of my systems and power steering while operating the vehicle.

On March, while I was leaving to take my children to school, I discovered a loud, heavy metallic knocking sound coming from the engine of my 2019 Ram 1500 Classic. As I depressed the gas pedal, the knocking frequency increased immediately with the engine RPMs. Prior to this total failure, I had noticed the truck feeling hesitant and "stuttering" when I was trying to accelerate from red lights in the days leading up to the incident. ​Because I was concerned the engine would stall or fail completely while my children were in the vehicle, I immediately stopped driving it. A subsequent inspection at Don White’s CDJR confirmed DTC P051B-00 (Crankcase Pressure Sensor Performance). This fault is a recognized indicator of excessive crankcase pressure, which the federal safety agency has identified as a precursor to sudden engine stalling and fire risks in 3.0L EcoDiesel engines (Ref: Recall 19V‑757).

First off the service shifter keeps coming on and off every time I take it to the dealership it’s off so they can’t read the code. Then the parking sensors keep coming on saying unavailable. Today when the service shifter came on, it went right back off and then when I went to turn onto the highway it felt like the truck stalled for a second then it started driving normal again and down the road. The service shifter light came back on, then went off. All recalls have been fixed on this vehicle and when I took it in and was charged $300 for a diagnostic, they couldn’t figure out what was wrong because the light wasn’t on anymore.

Incident Description: I am reporting three recurring safety hazards with my 2019 Ram 1500. ​1. Intermittent ABS/ESC Error: The vehicle recently displayed an ABS error message on the dashboard. The error cleared itself after the vehicle was power-cycled (shut off and restarted). This intermittent failure of the Anti-lock Braking System and Electronic Stability Control is a severe safety risk, as the system could fail during an emergency braking event. My VIN is currently excluded from Recall 24V‑653, despite my vehicle exhibiting the exact symptoms described. ​2. Unintended Forward Lunging: Before reaching operating temperature (cold start), the truck abruptly lunges forward while idling or under light braking. This occurs without driver input and has been reported by numerous other Ram owners as a cause for rear-end collisions. ​3. "Shift into P than Desire Gear" Error: While coming to a stop, the dashboard displays "Shift into P than Desire Gear," and the transmission slips into Neutral. This causes a sudden loss of motive power in traffic. I am aware of reports where this has caused vehicles to "lock up" or stall at higher speeds. ​Safety Risk: The combination of an unpredictable transmission (lunging/slipping to neutral) and an intermittent ABS failure makes this vehicle unsafe to operate. The manufacturer's current recall list for the 2019 model year is clearly incomplete, as my vehicle is suffering from these documented defects but remains ineligible for a recall repair.

I bought this truck 11/13/2025 and it has been in the shop since I bought it. It’s been “fixed” 4 times, including replacing the fuel pump. The vehicle is still stalling out and the same check engine code po62A keeps popping up. The engine light has popped up right after I’ve picked it up from the mechanic every time. It’s been to 3 different mechanics and no one can seem to fix the issue. It has become unsafe for me to drive. The dealership is no longer returner my calls or helping with these issues. I’m stuck paying off a vehicle that isn’t properly running.
