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.

I am writing this for my elderly father. He has a 2015 Ram 1500 diesel pick up truck that falls under the eco diesel settlement (class action lawsuit). My dad had the approved emissions modification (aem) that was required to update the emissions control software on May 28, 2019. After the aem completed by the dealer, the truck had throttle issues. When my dad pushed the pedal to accelerate, the vehicle would significantly lag to the point of not accelerating. This is a **continuous** and dangerous condition that was caused by the factory supplied software update. My dad made a complaint to the dealer three hours after the aem was updated on 5/28/19. He also complained to the dealer on June 6, 7, 8 2019 and on many other occasions. They tell him it could take 6 months to fix this dangerous condition. The factory "fix" has now created a dangerous condition. The dealer either can't or won't fix it. Many people have apparently complained to the dealer to where the dealer is now advising vehicle owners to not install the factory aem "fix". the dealer tells my dad that factory/corporate is working on a fix.

After the emissions recall fix, the vehicle now has a 5-6 second peddle lag when taking off. It is more noticeable when cold but still has lag when warm. It has almost caused me to be broadsided several times. Also noted a 5-6 mpg drop with the emissions software update. They claimed the update wouldn't effect drive ability or mpg but it did and bad

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.

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.

After having the aem (approved emissions modification) done for my vehicle I have noticed an extreme lag in engine response. When pulling out into traffic from a stop it takes at least four seconds for the engine to respond as it used to before this update. There have been several instances, even taking this response time into consideration before pulling into traffic, that I have almost been rear ended because of the lack of response or acceleration. A check on any Ram ecodiesel forum on the web will find many other owners having this same issue. All agree this is a safety hazard and will eventually result in someone's death. I will put today's date in down below because this is not a one time occurrence it is a daily occurrence with this vehicle.

After resolving recall for emmsuons on my 2015 Ram 1500 ecodiesel, the throttle response is lagging. After I make a turn onto a road the truck fails to accelerate when the gas peddle is being pushed. It has about a 3-4 second leg time. It is especially bad in a 90 degree turn going through a green light onto another road. I've almost been rear ended by trafficking that was originally 150-200 feet away when I originally turned onto the road. The lag is also noticed in passing situations.

After aem update their is a throttle and turbo lag that has put me in harms way on numerous occasions. When making a left or right turn the engine fails to accelerate for some times up to a block making it impossible to merge safely with traffic this has resulted in numerous extremely close calls. Both on city streets and highways the problem is in the new software that updated the required aem this problem is being ignored by fca and you how many accidents or deaths before you act?

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.

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.

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

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

Since having the approved emissions modification done on my Ram ecodiesel the truck will not accelerate properly until the engine seems to reach full operating temperature. When I attempt to pull onto another highway the engine bogs down and acts like it is going to stall. I believe this to be an unsafe driving condition. With colder weather approaching I am concerned this issue may worsen.

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.

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.
