This pertains to my 2015 Dodge Ram with the 3.0 liter ecodiesel engine. Ever since I got the required emissions control engine and transmission software update from Fiat Chrysler automobiles (fca), my truck's engine performance has been affected to the extent that I cannot depend on it's excelleration. I press on the gas peddle, and the engine hesitates severely before it accelerates. From a stop sign or a red light, the hesitation is such that I won't try to cross the intersection if there are any cars either to my right or left. Similarly, the hesitation and acceleration lag makes merging onto a highway a safety concern. The trucks fuel economy has also been negatively affected. I urge the NHTSA to compel cfa to reverse the software update, or fix it such that the truck is no longer a driving safety concern.

The contact owns a 2015 Ram 1500. The contact stated that there was a software patch update required for the vehicle. The contact took the vehicle to healey Chrysler, Dodge, Jeep, Ram (557 NY-52, beacon, NY 12508, (845) 831-1148) for the update to be performed. After the update was performed, the contact stated that the vehicle would not move when the accelerator pedal was depressed. The contact stated that it took 10-15 seconds before the vehicle would move forward. Also, while driving on a highway, the vehicle would not accelerate over 70 mph. The contact informed the dealer of the vehicle's lack of performance. The dealer stated that due to the system update, the vehicle would take time to become accustomed to the update and that, over time, the vehicle would resume normal driving. The contact stated that the failure continued while driving home. The manufacturer was notified of the failure and stated that they were still awaiting another software update to correct the failure. The vehicle was not repaired. The failure mileage was approximately 100,000.

Extreme lag during acceleration has almost resulted in multiple accidents. Work commute has me turning left onto busy road with limited visibility due to blind corner and I've almost been T-boned/rear ended because of the lag between giving the truck gas and actual acceleration. This is becoming more prevalent as temperatures drop. This morning I spun out trying to avoid being rear ended while pulling out because the throttle goes from lag to full throttle with no gradual acceleration.

2015 Ram 1500 ecodiesel. Consumer writes with concern to delay in acceleration. The consumer stated the manufacturer was notified and knew of the defect. The manufacturer stated the vehicle was safe to drive, but the consumer disagreed.

- Bartlesville, OK, USA

The contact owns a 2015 Ram 1500. While driving, the electronic throttle control indicator illuminated and the vehicle entered into limp mode. The contact also stated that the vehicle did not exceed 1,500 rpms. While driving up a hill, the vehicle did not accelerate over 5 mph. The vehicle was taken several times to clovis Chrysler Dodge Jeep Ram (395 West herndib avenue, clovis, ca 93612, (888) 696-0723). The dealer replaced the map sensor, coolant sensor, and the vehicle computer fault code was cleared. The contact was not sure if the repair corrected the failure because when the vehicle was driving 8,000 to 10,000 miles, the failure recurred. The manufacturer was contacted and provided case number: 5874636. The failure mileage was 71,676.

My vehicle was recalled for an "approved emissions modification" aem. It was stated that, "the aem was not expected to change any of your vehicle attributes...etc" after my vehicle received the aem it changed my vehicle's performance and safety. 1. the vehicle lost the low end power and you have to step on the gas just to get the vehicle to respond. I've experienced lag times that exceed 4 seconds. This happens either from being at a full stop, casual, or freeway driving. 2. when going up a steep hill at slow speeds (15 mph for example) the vehicle shifts up until the truck bogs down and almost comes to a stop. Pushing on the accelerator revs the engine up, pauses for a few seconds, then drops into a low gear and jerks forward. This lasts momentarily until the vehicle upshifts again and bogs down. This cycle is repeated over and over if you have to ascend slowly. 3. when accelerating unto the freeway, the transmission will not shift into 8th gear. It holds at 2100+ RPM and won't shift up unless you take your foot off the accelerator! this vehicle is a hazard on the roadway and unsafe to drive. Additionally, the aem has caused my truck to get a 20% reduction in mpg. I have taken the vehicle in several times and opened up a case. I was just recently sent an E-mail reply saying "they" are finished with the investigation and, "your concerns with the vehicle's performance have been fully diagnosed by our certified service department and it has been determined that what you are experiencing is a common and acceptable characteristic of the vehicle's design; this means that the vehicle is operating within its factory engineered specifications and there are not currently any repairs that will alter the vehicle's performance to meet your expectations." Fiat Chrysler automobiles will not repair/restore my vehicle to be safe and meet the specs that I purchased!

The aem recall was completed and the truck has a horrible turbo lag, which almost caused me to be in an accident twice within 15 minutes of picking it up. Dealership will not look at it and this is an unsafe vehicle for road use.

My truck received the V08 emissions software recall before I purchased it in July of 2019. As with hundreds of other ecodiesel owners, I am experiencing a dangerous throttle lag when the engine is cold. If I try to turn left and merge into traffic, there is a several second delay before the truck starts building speed. I feel this could potentially cause a crash. I have unintentionally cut people off because of this throttle lag and angered other drivers. There are hundreds of people complaining about this after the V08 recall on internet forums. Fca is supposed to have a fix coming according to the internet but who knows if that is true or how long it will take. The aem was "not supposed to alter vehicle performance" according to the recall letter. Obviously that was not true. This is a dangerous problem that should be resolved in a timely manor. This should be addressed by a safety recall. Some are also claiming their vehicles are catching fire after the aem was performed.

- New Hudson, MI, USA

I had the recall from Ram for the ecodiesel recall and now the truck is complete unsafe. I can't even accelerate into traffic without getting nervous. The truck lags and the throttle response is terrible now. Instead of buying them back like Volkswagen did, Chrysler put us in death traps.

- Marlboro, NY, USA

The contact owns a 2015 Ram 1500. While driving 70 mph with the cruise control engaged in eighth gear, the vehicle downshifted into sixth gear. In addition, the check engine warning indicator illuminated and the fuel mileage decreased. The vehicle was taken to carlock Chrysler Dodge Jeep Ram Fiat of tupelo (966 cross creek dr, Saltillo, ms 38866, (662) 842-2277) where it was diagnosed that the egr cooler burst and was leaking. The vehicle was repaired, but the failure recurred. The manufacturer was contacted and referred the contact to the local dealer. The failure mileage was 72,435.

Did the aem recall emissions reprogram. The truck now has very slow acceleration when cold. You have to floor the throttle to get it to move when cold. Very dangerous when merging into traffic or leaving a stop. The fuel economy has dropped to 20-21 mpg from 25 and higher. It is a much different and not enjoyed truck anymore. Talked with dealer. They are very aware of the issue as almost everyone has the same problems. Nothing they can do but say "hopefully a different re flash or tune will be sent after the complaints" wishing now it was just a simple buy back offer.

- Fargo, ND, USA

I had the updated aem installed in my 2015 Ram eco diesel. Now at times I step on the gas and it lags really bad(no power). This could be bad while in traffic etc

After V08/V11 recall was performed I now experience loss of acceleration till warm up. Like a dead pedal. Also a loss of a confirmed 5-6mpg. It was stated in the recall we would not loose mileage. If we did it would be very minimal. 5mpg is not minimal. My truck will barely stay in 8th gear now. Just bouncing between 7th and 8th. Now everyone is worried about all the fires due to egr valves sticking open and causing the plastic intake manifolds to catch fire. My wife is very nervous to take it on trips or even park it in the garage. We had new smoke detectors added in garage incase truck does catch on fire. Please look into these issues. There are more than you think. Pedal issue, loss of fuel mileage, engine compartment fires. Thanks

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.

Fiat Chrysler (fca) recently settled a class action lawsuit affecting my Ram ecodiesel truck. After that settlement, I was required to get a software flash called the "approved emissions modificatoin" (aem). After receiving that software "fix", my truck drives notably different and is now very dangerous due to the huge drop in power and increase in turbo lag. Especially when the engine is cold or not completely up to operating temperature, I experience almost no throttle response when pulling out onto a highway by my house. There is a huge amount of turbo lag, to the tune of several seconds, which makes pulling out into traffic a very dangerous event. This was never an issue prior to the required aem update, so I'm filing a complaint to outline this drastic decrease in performance which is downright dangerous for thousands if not millions of Ram and Jeep customers.

When I got my truck it ran good pulled great and got fantastic fuel mileage. I had the recall done the VO8 ref lash, since that was done my mileage has dropped 5/8 miles per gallon their is a bad throttle lag and no power coming off a stop my egr has broken and replaced under warranty and one I can hardly get 21 miles per gallon by it self on the highway and the transmission will not stay in 8th gear like it did when I first bought it. I have been all over the eastern U S with no problem pulling enclosed trailers ands 35 hp 4/4 tractor getting 19 to 22 miles per gallon at 7/5 to 80 miles per hour and staying in 8 the gear. Now no power and you have to stay in it to make it pull and trans. Shifts from 6/7 all the time and fuel mileage is terable as low as 16.6 I will no longer use that truck to go on desaster relief any more because it is scared to drive. It use to be a fun truck to drive but not now I am 70 years old and a pree mechanic and this truck stinks now I am ashamed to talk it up anymore like I did when it was new I guess when it fails I will put it in the front yard with a lemon sign on it and leave it I am one dissatified customer and I have 4 Dodge but will not own another one unless these are fixed like they were when they were new.

Power is off, throttle lag is bad turbo will not spool up until high RPM, transmission won't stay in 8 gear with the slightest incline and shifts back and forth from 6/7/8 when pulling small loads and with big loads it use to stay in 8th gear almost all the time fuel mileage is down by 6/8 miles to the gallon all this has happened after the VO8 recall, had to have a egr cooler and pipe put on because it went into limp mode, truck is scary to drive now you never know when is will excellerate when you push the gas some times it will take up to 5 seconds before it start pulling and I have a I cling going out of my drive and it almost stalls when going out in the morning and after it warms up it will throw drivel when it finally strts pulling. This winter will be bad when it gets cold because it is bad sluggish in the morning truck is scared to drive now compared to before the VO8 flash.fca could come up with something to cure this problem and Mississippi has nothing to do with californiapolution standard. My truck was running fine and getting fantastic fuel mileage before this and now it hard to get 20/21 out of it on the road where I was getting 28/30 you could stand behind my truck befor flash and not smell nothing but now it will burn your nose. Test were run befor VO8 crackle and it met pollution standards how did fca get sued for passing the standards I guess cal just doesn't like diesels, don't think I will ever go to California or buy another fca vehicle I guess I will go back to Toyota when this truck quits which will be very soon with all the cells coming on now, we need help on a use to be very good truck. It was fun to drive when I first got it but not any more. I use this truck to pull a tractor all over the U/S for desaster relief work but I will not take it any more because of how it runs now, really scary to pull stuff now compared to before flash

After an emissions recall update was performed on my 2015 Ram eco diesel I now experience lower mpg and poor engine performance along with a noticeable change in transmission shifting.. at times when pulling onto a highway from a stopped position the vehicle hesitates for a bit then seems to accelerate okay. This has become a safety concern do to the fact it isn't consistent. I have to be extremely careful when accelerating because I was close to causing an accident a few times already. Before the emissions update I did not experience any problems.

- Selma, NC, USA

Did the flash upgrade to fix the recall V08 and ever since then it has no acceleration when coming off a stop. It has a lag of a second or two and is very scary when trying to pull out in traffic. It has such a lag that pulling out that that your not sure that you wont get in a accident.

- Helena, MT, USA

Involving the eco diesel emissions update performed on my 2015 Ram 1500 at the dealership by fca on 06/11/19 said it would not change the driveablity of the vehicle but it has, in the acceleration that is delayed or sometimes just not there at all, this is inconsistent and intermittent when pulling out onto a roadway I must take the possibility in mind that the vehicle might not get going into the flow of traffic, I find this to be a safety hazard for every day drivers. Thank you, please advise
