2019 Ram 1500 engine problems

“The contact owns a 2019 Ram 1500. The contact stated that while driving 65 MPH, the vehicle had a slight loss of automotive power, and the vehicle decelerated to 20 MPH. The vehicle was restarted, and the failure ceased. The contact continued driving and the vehicle was taken to a dealer to be diagnosed. The contact was informed that the failure could not be duplicated. The vehicle was retrieved from the dealer and while driving the failure reoccurred. The vehicle was taken back to the dealer where the contact was advised that additional diagnostic tests were required to determine the cause of the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 65,000.”

“Blown Engine- No prior indicators that were obviously present. Driving on highway and about 40 miles in, loud ticking noises. Truck previously had manifold bolt breaking issues so assumed it was an exhaust leak. Within another 20 miles, the engine light came on and engine noises noticeably increased. Immediately took it to Ram Service and was diagnosed with a failed camshaft and camshaft bearing wear/scoring. Issue was reported to Ram dealership and ultimately fixed at owner cost.”

“Engine seized resulting in loss of propulsion while driving on the freeway Vehicle: 2019 Ram 1500 EcoDiesel Mileage at failure: ~50,000 miles Purchase: Bought brand‑new in April 2020 Maintenance: 8 documented oil changes, all performed on schedule While driving with my family on 7/12, the engine suddenly seized without warning at highway speed. The truck lost power instantly. This is a serious safety concern because the failure happened during normal driving conditions with no prior symptoms. The vehicle has now been at the dealership for nearly 90 days with no teardown, no diagnosis, and no repair plan. Ram/Stellantis has not resolved the issue or approved an engine replacement despite complete maintenance history and the low mileage. A modern diesel engine should not catastrophically fail at 50k miles, especially with proper maintenance. This appears to be a premature and dangerous engine failure that may indicate a defect affecting other EcoDiesel vehicles.”

“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”

“I am filing this complaint regarding a known, widespread, and concealed defect in the 5.7L HEMI engine with Multi-Displacement System (MDS) installed in my 2019 Ram 1500 Laramie 4x4. I have maintained this vehicle with oil changes every 3,000 miles. Despite this, at every consecutive oil change I have discovered significant metal debris in the drained oil, including chunks and shards, some curved in a distinctive pigtail or coil shape consistent with lifter roller bearing cage material and cam lobe debris as documented in the known HEMI cam and lifter failure pattern confirmed by dealer technicians nationwide. Symptoms include intermittent cold start tick occurring multiple times over the past year, loss of power in tow haul mode at high RPM, and a power loss event following extended towing while idling afterward. My consistent 3,000 mile oil change schedule directly contradicts FCA's standard defense that this failure results from owner neglect. A class action covering all 2014 and newer Gen III 5.7L and 6.4L HEMI engines received preliminary court approval June 29, 2026, with filings alleging FCA knew of this defect since 2012 and actively concealed it.

“On XXX, approx. 1615 hours, I was traveling EB on I70 in [XXX]. The cruise control was set at approximately 72MPH. I was in the left lane of travel and both my wife and I heard a revving noise and as I looked at the dashboard, I noticed the RPM gauge was high, I hit the brakes and started to go to the right lane and the entire vehicle shut down. All within a matter of 5-10 seconds. The dash indicated to put the truck in park to start it. I was able to make it to the shoulder and get the vehicle stopped and in park. I popped the hood and looked around the engine compartment. I saw no fluids leaking and no steam or smoke coming from the engine. I then attempted to restart the vehicle and it did absolutely nothing. Vehicle was towed to a RAM dealership, [XXX] CRJD in [XXX]. The did a cursory inspection ad determined that the engine was seized up but gave no indication as to the cause. Recommendation was to replace engine at a cost of nearly 18K dollars. Upon conducting further investigation on my own, I discovered that the Z46 recall of the HPFP, described with total accuracy what I experienced on the highway that day. The recall was performed on my vehicle on…”
