On sunday, july 19, 2020, parked and turned on the AC. Start smelling something burning and white smoke started to come out of front and cab vents. Immediately turned off and let truck sit for 30 minutes and drove about ten miles and the white smoke and smell returned. Pulled over on the freeway to check under the hood for smoke. No smoke was coming from the engine compartment. So, we called dealership to see if this was normal for an ecodiesel truck. The smell and smoke gave passengers inside the vehicle headaches. We were made aware that this wasn't normal and needed to bring the truck in. The smoked continued to travel throughout the truck vents even after it was parked at the resident. July 20,2020 contacted roadside services and had the truck towed to the dealership. The dealership diagnostic was the heater core caused these problems. Passengers experienced headache from the smoke and burning smell. This is a safety hazard especially for someone that is unable to smell, especially if all the windows are up. The truck has less than 3,500 miles. This was a brand new 2020 vehicle and is still at the dealership being repaired.
2020 Ram 1500 engine complaints
Page 7 of 7: complaints 161 to 166 of 166, newest first, as owners wrote them.
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.
Check engine light came on at around 300 miles. Code p3497. Brought it to the dealer and was told it needs new lifters. Truck was in motion on a city street when light came on.
2020 ram 1500 ecodiesel has a serious turbo lag. When yielding and then accelerating, the engine power seems to just drop out, falls flat. By this time vehicle coasts into approaching lanes and then it will suddenly accelerate with a burst of power. I feel it is turbo lag but may also be that the transmission is not down shifting in time in addition. I've heard numerous others mention this and it's something that I have to watch for constantly but cannot catch it everytime. This specifically happens every time I go to exit my long driveway onto a 4 lane hwy.
Throttle response or acceleration lag after letting off the gas to change lanes or slowing for corners etc. Has happened at end of exit off the interstate after stopping at stop sign, then proceeding to make a right turn into the lane. Upon pressing gas truck seems to "coast" or wait a few seconds before realizing it's getting gas then will suddenly accelerate. You have to wait and not give it gas for a few seconds for it to catch up.this causes a problem when changing lanes in town in traffic. Appears to happen mainly at slower speeds. Such lag could cause you to get rear ended a lot can happen in 3 to 5 seconds. Have had vehicle to shop, inspected and no signs of anything wrong upon testing. Has happened again, will take to shop again. This has happened 5 or 6 times now in less than 30 days of ownership. Truck now has 1078 miles on it.
3.0l gen 3 ecodiesel engine has excessive lag and delay in throttle response. While traveling at steady speed in lower gears 3rd, 4th, or 5th and then depressing accelerator pedal to increase speed, engine will not respond until three to four seconds have elapsed. This creates a significant hazard when attempting to merge into traffic or cross traffic during a left turn. Prior experience with multiple gasoline and diesel turbo-charged vehicles has not presented this issue to me. The 2020 ram 1500 ecodiesel has a magnitude of turbo lag and unresponsive throttle that is quite dangerous.
