2016 3500 Aisin poor throttle response

[Bob4x4]

What your missing here is when you have 2 different truck like I did a 14 and 16 at the time, and the 14 was fine so you get used to it then try to enter or cross a highway with the 16 not remembering how this truck acts and it falls on its face in on coming traffic. It sucks having people flash lights flicking you off thinking you didn't see them when the truck has a 3 second delay. I know some of you guys who never drove a truck with this problem think oh it's no big deal it's a BIG deal when your truck does it. Not all trucks do it but most of the Aisins do. When my truck was ther there was also 4 others ther with the same complaint. I actually had a conference call with my dealer a third party arbitrator from the NHTSB and someone at Chrysler. The arbitrator said since the trucks are designed this way and there was no accidents yet Ram didn't have to cover anything or buy back truck. I told the Chrysler rep if they don't at least give me fair trade on a new Ram to try and see if that was better I would never buy one again. His response was simply OK. Nuff said I will never buy one again. Maybe if more guys complain or switch brands at least for a while they will fix the problem. Not saying my new Powerstokes are better engines than Cummins (they probably are not) but it's Rams programming causing the issue not Cummins.

I have driven many,many examples of the affected trucks,none of them would exhibit the so called dead pedal without the on/off the pedal technique.Less than stellar acceleration will happen if the pedal is slammed hard,roll into it and she’s fine.Annoying yes unsafe not in my mind.

I guess I am lucky never had an issue, much be my magical 4.10's.

Same issue with a 2014 68rfe 2500, dead pedal only when on the throttle, then off, then back into the throttle. On the other hand the 05 5spd Alison D/A would slowly catch up to throttle position leaving you high and dry while trying to pass another on a two lane HWY. The Dead Pedal on the CTD is different in that, if you don't let off the throttle, it will respond briskly to the throttle position, but let off then back on is when I would get the delay. (Dead Pedal)

Have you filed a complaint on www.safercar.gov ??????

I filed a complaint they told me since there wasn't a serious accident yet they can't do anything. So I said I have to wait till me my wife or son die or be critically injuredfor you to do something something? They said they are not saying that. Was a waste of time typical government agency.

Mine wouldn't do it all the time so if you just drive a few examples you have no idea what the problem is drive one every day for a few weeks you will never want one again. Mine did it no matter what roll into throttle or mash didn't matter.

I worked on them for a living,I may have understated how many
I have sampled

Well you didn't work on mine did you. I even told the service tech to drive it for a week and they wouldn't because of the problem. They must've known it was a problem they are the ones that contacted ram. And driving a few samples is different than driving one every day for a week straight. And if it's not a problem why is there so many threads on it. Sounds like a poor Rams guys feelings got hurt.

I have done some extensive test drives for customers that did not want to mess with the procedure for getting all the monitors to run

This is a real problem. There should be little to no torque management in these trucks with the transmission being built to match engine. Engineering anything less is unfortunate at best. Traction control can kick in if traction lost. Other than that the trucks should not be designed to put out more than a transmission can handle with reasonable accelearation.

When my 03 can beat my 17 off the line and designed that way. I e stock then there is a design flaw in the new trucks.

Just because there are no reported accidents due to this lag doesn’t mean there were not some due to it. It also speaks to the drivers in this thread that realize it’s happening and have to make adjustments to make up for this design flaw.

BD throttle booster doesn’t really correct the issue and if it is torque management programming I guess I should have figured it wouldn’t.

I am going to report to safecar or whatever that site is and also speak to my dealer to see if he will get crappy on me if I add a tuner to try to get the lag out even if it doesn’t add more power.

We just need lag out. 3-4 seconds is too long to wait

 

[Learjet]

I have never seen this lag...I wonder why some have it and some don't? My 2017 is pretty responsive from a dead stop or anytime.

 

[brillmtb]

You are very lucky then but then this concerns me more. Now it sounds like a defect if some have it and some don’t.

I sure work like to try one of these dead pedal trucks for a test drive and have the owner drive mine to compare. SnoKing

Next time your in Reno look me up

I would also!

I don't come to SoCal anymore or I would let you drive mine Bob. Dead pedal all the time, not just when you accelerate and back off and on it again. Even with the BD device, it still has the lag. As I mentioned in earlier posts, just not quite as bad in the first three shifts. But just as bad in the upper gears. Don't understand that either. You would think it would help all the way through. Buying this truck has been one of worst decisions ever. Well....if you don't count the first two marriages. The second worst decision with the truck was not understanding that Ca has an 18 month limit on the lemon law. I thought it was two years, like other states, and waited too long. If it cannot be fixed, it's a lemon. But trading it in will cost me major bucks and I would get screwed again on the devalue due to the issue. No way out of this scenario for me. If you go on vacation to Yosemite this year Bob, look me up. I'm about 40 miles south of there. It would be nice to share the misery with someone knowledgable on this forum to give me a little credibility.

I tried to get Ram to give me my money back or a fair trade in price with the lemon law. But the lemon law doesn't apply to this problem I was told by the NHTSA because this is the way they are designed by Ram. Doesn't make much sense to me it sucked having to lose $26,000 trading my truck in to the Ford dealer and only owning my truck for 11 months. But I can understand why they wouldn't give me much when they had 2 other trade in Rams on the lot with same problem as mine. They ended up sending all 3 to auction 7 months after getting mine. They told me after test drives people lost interest.

 

[MJWenrich]

Right on point 2016HO. I keep hoping the aftermarket will come up with a fix. Maybe if ALL the trucks had an Aison, and All had the lag there would be enough of a market, or accidents to investigate and manufacture a solution. Until then, I enjoy the HP when I can get it and just drive vewey, vewey, careful. Those old enough to recall Elmer Fudd will appreciate that.

 

[RVTRKN]

Back in the day, without all the electronics involved, and very high HP/TQ, just to keep up with the Jones. I welcomed a slow but high torque, @ 600, when climbing a steep grade from a dead stop and be faster than traffic when reaching the top @ 15K GCW. Whats the difference if you have to drive the very high torque truck the same? Would I spin the tires? NO. Would I want to break the land speed record? No. So stay out the pedal with slow acceleration and and keep RPM's in the sweat spot. As an example, traveling south on D street on to the South bound I-15 in Victorville CA is such a steep climb, and my 04.5 climbed that with ease at 15K GCW. Just stay off the throttle until a fix is in the works, like I did with my 305HP 07 C&C, chocked with a DPF. Now its got EFILive and plenty of power.

Filed with safercar today. We will see what happens

Earlier in this thread it was stated that 5th and 6th gear not the lower years needed torgue.
Actually you need torque in the lower years to get moving especially with a heavy load, you also need torque going up hills.
If you go with simple definitions of torque and horse power, torque = how much work the truck will do. Horse power how fast it will do it.
I would assume the computer is limiting horse power, because you need torque to get going. As the truck picks up speed more horse power. Of course max ttorque come in at low rpm and straight lines to the rpm where the max horse power is reached ( vp44 engines and common rails do this not 12 valves). Fuel for thought!
