The failure pattern owners describe

Owners describe a range of powertrain failures, but transmission defects dominate the complaints. The most common and dangerous issue is the transmission unexpectedly shifting into Neutral while driving at any speed (10-80 mph), causing complete loss of propulsion. Drivers report dashboard messages saying "Shift to P then desired gear" and having to pull over in traffic to reset the transmission. Dealers cannot replicate the issue in most cases and provide no fix, with some transmission replacements failing to resolve it. The 8-speed ZF transmission develops hard shifts, delays engaging, and enters "limp mode" limiting speed to 30 mph.

Engine failures also stand out. One owner's Hemi 5.7L filled with metal shavings at 50,000 miles from a disintegrated lifter assembly—mechanics say this is a known defect affecting many owners at this mileage. The engine required complete replacement at $10,000+, and Fiat replaces failed units under warranty with the same flawed part.

Two owners reported engine fires: one while driving a family of three on vacation, and another at highway speed where the vehicle shut down leaving them stranded at night. One truck suffered a transmission heat exchanger failure mixing coolant with transmission fluid (which is flammable), nearly catching fire due to the short commute distance.

Electronic and electrical problems include complete system shutdowns at highway speeds with no warning, service shifter warnings starting at 3,000 miles, and CAN bus connector failures causing multiple systems to drop in and out. eTorque hybrid systems fail with grinding noises and fuel economy loss.

Repair costs are substantial—transmission replacements ($10,000+), engine replacements ($10,000+), differential and axle failures ($3,000-$5,000)—often at mileages well below 100,000 miles on vehicles with light use.

Common questions

How serious is the powertrain problem on the 2019 RAM 1500?

It's a documented issue but not catastrophic. 183 complaints have been filed. Repairs average $2,500 and most owners catch it before it causes a breakdown.

At what mileage does the powertrain typically fail?

Across the 52 complaints that reported odometer mileage, most powertrain failures cluster between 8,504 and 48,000 miles, with the median around 19,414. A quarter of owners report trouble before 8,504; a quarter make it past 48,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.

What does it cost to fix?

Independent shops typically charge around $2,500 for powertrain repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.

Are there any recalls related to powertrain?

No active recalls currently cover powertrain issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
