This is fascinating:

They don't say specifically but apparently with MDS activated and depending on the engine speed, the timing chain is being unloaded (?) and destroying the guide. WTH...

Wow!! Very interesting . So would it be obvious that chrysler is denying what they already know? My truck is Canadian or at least purchased in Canada so maybe a reason as to why no such reason as to not knowing this. Like I said when I deal with chrysler it's seems they are really holding back some info. Any way case in point. Obviously our trucks have this same issue it seems and we are getting the run around. It's to bad the truck wouldn't just get to major damage like report suggest it could ton wake these people up. Anyways I'm in process of requesting all work ticket info be packaged in a envelope for me as well as the owners of the dealerships info. Requested by my lawyer. Hands are tied and just frustrated. It's really not my job to be as patient as in have been and reading forms trying to help fix my truck. That's why in have extended warranty. But this thread really sheds some light on this issue. These techs may wanna start looking in this area instead replacing lifters etc. Unreal.

 

That may be so. My dealer urged me to contact Chryco Customer Care. "For what", I countered. The dealer tech confirmed the MDS racket so why am I being left to carry the ball?

Mine too but not a factor. Truck was built in Warren, Mi, the engine hails from Mexico. Build date was during the dark days of Daimler Chrysler and about the time when all the pundits forecast the Chryco would bite the dust.

No doubt about that! There is stuff thay do not want the customer to know!


Yep, get'n hosed we is!

I feel you pain/frustration and wish you well in attempting to resolve the issue. Please keep us apprised of your initiative.

Cheers,

I have notice a ticking noise in my engine when ECO mode light is on between 20km/h and 50km/h, ticking noise is fairly loud, echo’s on buildings and cement walls. Whenever I am coasting with in those speeds, I here this noise. If I accel it goes away if I go to neutral goes away if I press tow-haul it goes away. So I am pretty sure it's related to MDS but not sure what is wrong, dealer scheduled an appointment july 14 cannot wait to see what they will come up with.

 

So here's another update. Short version. Basically once again chyrsler has said to dealert that not to do anymore work to truck. If it's drive able and poses no safety hazard then customer should drive. Even though it's a prominent noise we all hear and have full warranty. Chrysler and dealer won't do anymore. Their only fix is to roll me into a new refinanced truck. That's the joke around the shop. Not happening. Today I gave the dealer a cut off time to seriously show me it's worth. They basically are waffling and saying it sounds like a program update needed and since their is.no update. Not much can be done. Update? Seriously? It's the FN MDS system. So now I requested to speak to the owner next week and have also gotta my lawyer on board with this to at least her this storey and.any like it out. SoMe one on here early posted two great articles and one specially on this page about how the engines have been recalled in the states ( 50,000) due to timing chain wear with the MDS. To me this exactly.makes sense. What I also believe is that since the MDS / Hemi is a patent by chrysler which any issue = their fault don't want to come clean. How in God's green earth does a massive recall happen in the states but when I call Chysler canada they don't even wanna discuss such an issue. I've said it before. Will say it again. I strongly believe that chysler is fully aware of the issue and the dealer is to an extent. Either way we are talking millions in replacements and fo now their fix is to have us frustrated and most do get to a.point and just refinance. Not happening with me. Options for chysler and dealer are simple. 1. Fix the truck! But won't cause you do for one you'll do for all. They'll simply take their chances with a lawsuit down the road I guess once people get injured. 2 . Just replace the damn motor!. 3. Take my truck of.my hands and give me a swap of the same vehicle ( yes brand new) after 2 and half years of this it's deserved. 4 . Buyout my truck, I keep it and give me warranty for as long as.I own. Now I have been patient for a long time and never brought these up, but now it's quite simple . If you can't fix then what's my option. Other than buying me out. Selling my truck and then refinancing in a new one? Yeah that sounds like a customer satisfaction right there. Anyways sorry for rant. Of this timing chain is the problem like stated in previous post that does pose a major safety risk so for chysler to suggest otherwise is crazy. If any of you still have this issue going on feel free to email me. I will present numbers to my lawyer and including recall down south to prove there's a problem . We are not crazy. Don't provide my thong to specific . Mayne just first until last name. Make year of model. I will gather that list and.present. I'll do.my best to get something going. Chysler needs to.understand a few of us are fed up and a little.more serious then they think. For the last guy who just posted good.luck. but I'm sure your going to he given the same gears we have. Anyways send Ino if you like including Vin also to fournier_jp@hotmail.Com

Just trying to help folks. Anything you guys can do would be great also. Refinancing should not be your only option. That's a win win for them. We just want our truck fixed!!

 

ayWelcome to Rattling Hemi club. We're small in number and as such, FCA would like us to just go away. Your description of this malady is spot on - same diseased MDS system. Sadly, the expectation is that you will get little satisfaction from the dealer. Let us know how it goes. Maybe they'll surprise us!

Cheers

 

Yep, that would sure be nice. But I'm not going to hold my breath.

 

After calling FCA Canada to complain that is is not a normal hemi characteristic. i was asked to return to the dealer once more (7th time) for diagnosis and repair. i was assigned a case manager as well. the car was in the shop for a week but happy to report the mds noise is gone and cars power has been regained. Below please see what they did to fix the issue. i hope this helps as well with your trucks.

ps. the dealer said they found the fix on a website forum unrelated to dodge.

Very interesting. This is the first time I've heard of an MDS coast-down ticking noise in a non-Ram Hemi 5.7. There are some slight differences in the 5.7 valve train components between cars and trucks. I'm not sure about the chain or the harmonic balancer, but the tensioners are quite different.


Still, very enlightening.
