Vehicle emits a strong vibration in 1800-2000 RPM at every gear and speed when the engine is under load. The vehicle does not vibrate at this RPM range in park or neutral. Vehicle emits vibration through driver steering wheel, gas pedal, floor, and seat. Vibration also felt in passenger floor. Vibration causes booming, sounds in the cabin that are uncomfortable. Vibration is increased when in 4WD auto vs 2wd and 4WD high. Vibration is at its loudest at cruising speeds on highway when in the affected RPM range. Fca is unwilling to address the vibrations of the vehicle and refuses to diagnose and repair. Vehicle is described as "operating as designed" and this is a "characteristic of the vehicle" from fca customer service representatives and technicians/engineers. Vibrations causing headaches and nausea due to general discomfort of the cabin vibration. Issue did not exist upon purchase of vehicle, but rather developed after roughly 2000 miles.

There is a significant delay in throttle response on the 1500 eco-diesel. There are numerous situations and scenarios where you push the throttle down and the car delays for a few seconds before the engine increases power. I could be pulling out into traffic sometimes and sometimes I accelerate normal and sometimes when I push the gas pedal the car delays and I am stuck without any acceleration for a few seconds. You could attempt to speed up to pass on the highway sometimes and again sometimes it does accelerate and sometimes it does not accelerate at all.

Frequently, when slowing or coasting such as when making a turn or coasting prior to a stop - when it is necessary to resume acceleration their occurs a delay of 2-3 seconds where the drive train doesn't know how to respond. When it finally does it goes into gear abruptly followed by the late response to request for power from the pedal input. In particular this presented a safety issue when I was in a center turn lane getting ready for a left turn off a two lane hwy. When there was a sufficient gap to make the turn the delay caused a few heart palpitations when the vehicle would not respond. I was towing an atv trailer at the time and wanted to speed my entry to the side road I was turning onto. This fault has occurred many times now and is pretty regular. As an engineer I believe this to be a software issue. No updates are currently available.

Vehicle has consistent throttle input response lag. When applying throttle from a standstill there is a 1 to 1.5 second lag before the engine revs. The same lag occurs when but can last up to 3 seconds when attempting to increase acceleration from any given rolling speed. This is incredibly dangerous as it makes the simple and frequent challenge of crossing an intersection and/or overcoming slower traffic impossibly difficult to accomplish safely and without drama/stress. Delays in response cause the drivers to second guess their decisions and actions. The result will either be to lift off of the throttle (at which point the vehicle may decide to accelerate partially) or to take their eyes off of the road/traffic and check the instrument panel (at which point the vehicle may then decide to accelerate). If there is oncoming traffic, pedestrians or other obstacles, this can result in a major accident, injury and/or death.

On two separate occasions in the past week, the throttle pedal in this gen 3 ecodiesel engine has failed to respond upon pressing it to make a turn after driving the truck for a few minutes. I will drive a few miles, then stop in a turning lane awaiting a chance to complete the left hand turn across traffic, and when I apply pressure to the throttle pedal nothing happens. It's as if the pedal has been unplugged. As I continue to hold pressure on the pedal, several seconds will go by and then immediately there will be a harsh jerk and the truck will immediately apply power. This is a separate issue from the terrible lag in throttle response that has been present since the truck was brand new. This loss of all pedal response only began to happen this past week, with approximately 3,800 miles on the odometer.

While stopped at light when I began to accelerate making a left turn the transmission wouldn't shift out of first gear. This is dangerous should you need to quickly move car out of way. Car went up to 5000 RPM before I release the gas and proceeded to side of road. Dealer couldn't duplicate, I asked them to flash the computer and they refused, saying any updates would be over the air. Which is not true. Truck is supposed to be equipped with tailgate ajar warning light, it is in manual and on my build sheet. Dealer tells me that its not. So there not putting in the correct equipment. This is dangerous since I had 2017 Ram that tailgate opened while driving before recall!!

The contact owns a 2020 Ram 1500. The contact stated that upon reversing the vehicle at various occasions, the vehicle abruptly stopped without warning. Neither the dealer nor the manufacturer were notified of the failure. The vehicle was not repaired. The failure mileage was approximately 700.

This has happened several times. When driving the Ram, with the gear in drive and in 2 wheel drive, the transmission will not shift out of first gear. Obviously, this is very dangerous for driving. This seems to be a recurring issue with the Dodge Ram and should be fixed or recalled. Similar issues with the 2019 Dodge Ram: Https://www.cargurus.com/cars/discussion-T77803_ds971922
