Fca issued a software update known at "aem" after they lost their class action lawsuit. I had my truck updated on 5/29/19 with the "aem", rotary shift autopark recall update, the seat belt recall update, airbag recall update, and the tailgate recall update. I also had a catastrophic egr system failure that made my truck inoperable for nearly three weeks. The vehicle is now utterly unpredictable. After the initial start, I randomly have no low-end power. The vehicle randomly lurches forward at full speed when I press the accelerator from a full stop. This morning I was turning left from a dead stop into traffic. I pressed the accelerator all the way to the floor and it barely inched forward for several seconds. Suddenly it hit full power and launched into the roadway, barely in time to keep from being T-boned by oncoming traffic. Soon thereafter I was in the middle of an intersection waiting for oncoming traffic to stop so that I could turn left. The light turned yellow and traffic stopped so I tried to turn. My truck stumbled and barely moved until it again, launched forward at full power causing the read end to skid out to the side and strike the curb of the sidewalk. Additionally, the vehicle now has a completely random shift pattern. When cruising at 55 mph the engine may be running at 1500 RPM or it may be 2250 RPM. The inability to shift correctly at high speeds means that I cannot reliably merge with, or overtake traffic. It also means that my truck cannot reliably tow a load without posing a threat to the general public. It's not predictable and it's dangerous.

After the V08 recall the drivability of vehicle is dangerous. The fuel consumption and the lag of the engine is also a huge concern but it handles totally different. While it still seems decently reliable, for now, everyday unsureness of trying to anticipate how the vehicle will handle during driving is the primary factor.

The contact owns a 2015 Ram 1500. The contact received a letter from the manufacturer regarding an emissions update that was required via a lawsuit against them. The contact had the emissions updated at cortese Chrysler Jeep Dodge Ram (2400 w henrietta rd, #2324, rochester, NY 14623, (800) 952-7892) in June of 2019. Since then, the contact stated that the vehicle's overall performance decreased by 25%. the vehicle also lost power, lost acceleration, and the cruise control operated intermittently. The manufacturer was contacted and a case was opened. The manufacturer informed the contact to call the dealer and inform them of the failures. The same dealer was contacted and stated that everything was fine; however, the contact informed them that the vehicle would hesitate when the accelerator pedal was depressed and then accelerate suddenly. The manufacturer stated that the vehicle was operating as intended and closed the case. The failure mileage was 62,000.

2015 Ram eco diesel. Recently, Ram and Jeep were involved in "in re: Chrysler-Dodge-Jeep "ecodiesel" mdl, " which resolved legal claims asserting that the vehicles do not comply with federal and state emissions regulations and that Fiat Chrysler made misrepresentations to consumers regarding the vehicles. I pulled this info from the eco diesel settlement website. In response to the above, customers were to get (3) things; (1) V08 software update; (2) money, dependent on your ownership status; and (3) a 10 warranty extension. I had the V08 software update completed at the end of may, 2019. Since that update, my vehicle has had poor performance with lack of power and acceleration. Within a week of having the update done, my check engine light was on with the electronic throttle warning light on as well. I took the vehicle to the dealership and they fixed the issue; however, the lack of acceleration and power remained. Through June and July this lack of power and acceleration continued. I then took my vehicle in to the dealership towards the end of July and they opened a star report and told me this recall is having negative effects on a lot people's vehicles. I then took the truck back and was driving at the end of July when the electronic throttle control warning light came on again. This time, there was a smell similar to burning electrical. I pulled over and the within minutes the truck was engulfed in flames. Fire personal were called and the fire was put out, but not before it engulfed the engine compartment and front of the cabin in flames. I filed a claim with my insurance and contacted fca. Both parties sent fire investigators out to look at the vehicle. Fca says, with the info at hand, the fire can't be associated with a manufacturing or assembly error. I also contacted the class action attorneys and sent them information from the fire as well.

The contact owns a 2015 Ram 1500. When the engine was cold, the accelerator pedal would not respond. The contact had to apply excessive pressure to the accelerator pedal to increase the speed. The contact stated that the vehicle would jolt and the tires squealed. The vehicle was taken to dishman Dodge Ram Chrysler Jeep (7700 E sprague ave, spokane valley, wa 99212), but was not diagnosed or repaired. The contact called the manufacturer and was advised to call NHTSA. The failure mileage was unknown.

I have received various recall notices on this vehicle which I would like someone to look into this to see if this car qualifies as a lemon. These items have been fixed by the different dealer ships, but have more than 5 recalls is a bit too much.

Ecodiesel - following recall aem (approved emissions modification) update, throttle response is extremely poor at times. When turning onto a roadway from a stop the vehicle is sometimes very slow to accelerate, risk of collision due to being unable to increase to safe speed. When trying to accelerate under this condition the vehicle will suddenly abruptly accelerate which sometimes results in wheel spin (loss of traction). This happens in dry and wet conditions.

Epa has required an aem flash update for my Ram ecodiesel. This update has become a major safety issue. Due to the update, when the engine temperature is below 160 degrees Fahrenheit, there is a 3-5 second delay in acceleration. 0N 7/8/19, leaving the dealership from receiving the epa regulated update, I had to make a left turn across traffic. Not knowing what the aem update had done to my vehicle, I pulled out of the lot and tried to accelerate. My vehicle rolled into 3 of the 6 lanes of traffic. I had the peddle as far as it would go and during that 3-5 seconds, my vehicle was sluggishly going 4 mph. Once that 3-5 seconds passed, the vehicle then accelerated rapidly as it should with the peddle to the floor. Once the engine temperature get over 160 degrees, the delay drops from 3-5 seconds down to 1-3 seconds. I have learned to not chance anything pulling in to oncoming traffic. That one day leaving the dealership, I was lucky to not have been injured in a serious accident. This safety issue is something that needs to be addressed.

On 7/29/19 at approximately 12:30 pm, was traveling between 60 - 65 mph, West bound on interstate 40 at N.C. mm 31, the truck lost power (limp in mode), the check engine & service automatic throttle control system lights came on. Noticed a small amount of white smoke emitting from the underside of the truck. Coasted off of the interstate and came to rest in a used car dealership's parking lot. Turned the truck off and opened the hood where I found an approximately 8' flame projecting from under the plastic manifold cover. Doused the flame with a bottle of drinking water and took the plastic cover off where I found the wiring harness sheathing engulfed in flames. Extinguished that with an abc dry chemical extinguisher. Currently the truck is at waynesville Ram with no updates as of yet. Had the egr recall completed on 6/19/19 at waynesville Ram and had noticed decreased power and fuel mileage since but the decreases were minor and just accepted as fact from the recall. I am very concerned at present after researching this situation and conversing with others who have experienced very similar events with the same motor.

I had the recent recall done on my ecodiesel for the emissions failure according to the epa and ever since ive had the recall ive had roughly when I start it in the morning about a 4-5 second speed delay or pedal lag even if I push the pedal to the floor. After it warms up and ive been driving it a while it improves but the delay is still there even after driving for my job, I'm a Pilot car driver/escort for oversized loads, and after driving all day I still have a 1-3 second delay no matter how hard or soft I press the pedal. Ive taken it to the dealer and best they told me is either fca will have to come out with an update or to go buy a pedal commander or something similar to immediately correct the issue but could possibly void even the extended warranty I got with the emissions recall. Which if I had known all of this I would said to hell with the any recalls. I feel this is going to cause me to wreck by either hesitating because I know theres the lag or im going to pull out and not be able to get up to speed within a reasonable distance.

After receiving the updated engine programming recall on my ecodiesel Ram, the throttle response is dangerously slow when accelerating from a dead stop. There is a several second delay from me applying pressure to the throttle pedal and the engine reacting and accelerating. It's very difficult to judge when turning into traffic because of this delay. Could easily cause someone to be rear-ended because the truck does not accelerate as expected. This was not the case prior to the recall.

After update to resolve the emissions recall issue (ecodiesel settlement), my truck has dangerously poor response to acceleration. It is a life safety issue. After the initial update, I had to bring the truck in a second time because the emissions updates ruined the emissions sensors. Leaving the dealership, I pulled out into traffic on a state highway with plenty of room (at least 200 feet) and after hitting the accelerator, the vehicle stalled for approximately 5 seconds before finally responding, nearly causing the vehicle behind me to run into the rear. If this issue is not resolved, people are going get killed on the highway.

My 2015 Ram 1500 ecodiesel recently received the V08 recall. Two weeks after the recall the truck broke down on the side of the road on July 01. The truck was in the shop until 07-19. I drove the truck home from the shop and did not notice extreme lag at that time. The. I got I to the truck at the dealer the truck had been idling and was almost to operation temperature of 200' Fahrenheit. The next morning upon first start up I drove the truck and was immediately almost in a accident as when the truck was cold with temps below 150' there was an almost 5 second lag from then the gas pedal was pressed and the truck would accelerate. The truck has severe lag upon acceleration and will not accelerate reliably until the truck has warmed up to almost 200' which takes almost 15 min. The dealer has admitted that there is something wrong but has no way of fixing the problem as the truck is not producing codes to aid in diagnostics. In my opinion the truck is unsafe to drive and should be fixed by Fiat Chrysler.

Emissions recall update involving V08 has forced my truck performance to now cause for concern the way I am able to drive my truck safely. The pedal response is terrible compared to the "stock software" and is a slow reaction until the truck is "warmed" up to about 150F degrees. Because this software update is released in the summer it should take less time to warm up but living in Michigan, the truck will take a lot longer to warm up during the winter months which will a) not allow me to drive safely through an intersection any more and B) force other drivers to hit their brakes due to a lack of acceleration my truck now has and either hit me or have them avoid my truck causing accidents. The lack of acceleration or "lag" as it is called is for about 2-4 seconds which does not allow the truck to gain any speed worthy of traveling onto a road with traffic. The vehicle should be able to "get out of it's own way" like it was before the V08 was installed. Another issue is that once the truck is able to move because of the "lag" going away finally the engine is then over-revved at an un-normal RPM. The issue with that will be in the winter time when there is ice and snow on roads and the rear wheels will spin on that slippery surface. The most common occurrence for this lag is after start up and starting to drive my truck onto roadways or across intersections. The scariest moment was when I had a very reasonable amount of space to pull out onto a roadway, making a left turn, from a stop and a semi truck caught up to me from the right and I was forced to go to the middle turn lane instead of a drive-able lane to avoid the truck because my acceleration performance had diminished to nothing for the 2-4 seconds meanwhile more oncoming traffic is headed towards me as well. The truck seems to go into traffic fine, but will not speed up regardless of pedal position.

Since having the emission recall update installed, acceleration has been excessively reduced at engine temperatures below 150 degrees. The vehicle does not accelerate at a safe level from a stop. This has nearly caused multiple accidents due to the unexpected slow acceleration.
