It's 2018 Durango GT
3.6 Engine
I use 87 regular , I used 89 and it still rattles.
Any owners have the same problem?

 

TJ:
At what rpm does the rattle start? A '18 with 16K should be under warranty. You took it to a dealer, and what was their diagnosis?

Don

 

Thanks for reply. Don't recall the RPM, however last time I recorded it it was at 40 mph.
Original dealer couldn't not find anything wrong with it, even tho I showed the advisor the video of rattle noise before I left if at dealer.

 

Anyone

 

TJ:
Where are you located? If you haven't yet, I would go back to the dealer, and request that one of their mechanics ride with you so you can show them this noise. If they refuse, it is time to find another dealer. From what you describe, possibly you have a bad tank of fuel, or the engine management system is not doing it's job of timing the engine, hence the noise or rattle upon brisk acceleration.

San Antonio, Texas and I'll try it. Thanks

 

TJ:
Can you post that video somewhere, ans put the link here so we can take a look?

Don

 

Don, I would love but, I don't know how? I'm using iPhone to type, any way I can share video

 

Possibly upload it to You tube, and then post the link? Others may know of a better way.

I took truck to another dealer and had the service advisor assistant ride with me. The truck did make rattle noise and I pointed it out to assistant, when we got back assistant reported the noise to service manager.

They kept truck for a week and told me it was a retainer bracket holding a heat pipe along firewall, and when I got back the rattle still there?

Should I be concerned that this might be some engine problem?

 

TJ:
I would take it back, and inform them that the issue is still not corrected. They need to keep at this while the warranty is in force, so FCA can pay, and not you.

Thanks for your advice. It seems that they can't find the rattle noise no matter where I take it. The service advisor told me the technician looked around in engine and found the retainer bracket loose. However, it's still making the rattle, and it seems to that they know the problem but rather deny the issue and give it back to me. ??‍♂

 

Keep at it. Lemon Laws exist for reasons such as this, so if they can never solve your documented and confirmed issue, that's a path to consider as long as you keep getting it to the dealer and document everything.

 

I have it documented, from two different dealerships. I love my Durango; however you guys are right that Chrysler is giving me run around. What documents should I try to obtain in case I need to file a lemon law? All I have is the service reports, when I pick it up. Everything else has been over phone, which I'm sure Chrysler has recorded. I've also called Dodge Cares customer service number, and they never return my calls. ?

You'll have to check with Texas to see what the requirements are.

I wouldn't assume anyone has recorded anything or can access those recordings.

I would definitely stay on Chrysler Cares long enough to get a case number too so you have a reference point with them.

 

Here is the service report, I got from new dealer.

 

As you can see I take good care of truck

 

Rattles are one thing , but I am not sure they are covered under lemon laws.

I think it may help us here if you can make a video of the rattle.

 

I was thinking more of the "loses power" part as an actual possible issue besides just a rattle, unless that's not happening anymore.

 

I'd like to say, I'm not bashing Chrysler/Dodge or calling them out. I don't think they build defective cars to mess with consumers, I love this truck. I get lot of compliments, and it's a great vehicle and I'm happy with it. Thanks everyone for your response, the thing is the engine noise is louder. If I post video no one will be able to hear it. I believe that if nothing is loose, then something is wrong with engine. A problem that is slowly developing. This is not normal, I've had several new cars in the past and none made such noise. I'm bummed because this is my wife's daily driver and I really want my family to be safe, that is all.

 

Happens on my 2018 as well, a rattle for few seconds when lifting foot off the gas pedal but never bothered to report to the dealer as it will be hard to replicate since it happens randomly.

 

It doesn’t make sense to have an engine rattle with the loss of power and tech only found a bracket loose?
I’d believe in either engine knocking due to bad gas or clogged up cats but with the last the engine should also miss and throw codes. Also injectors clogged causing the rob of power, should also throw codes.

Where is the video op?

 

I'm confused by the title...rattle AFTER acceleration or coasting. Not sure how you lose power at that point???
If you were losing power during acceleration the dealer should be able to note that. Typically that type of problem would not just go away, but get progressively worse.

 

Durangorsm, exactly it doesn’t make sense but this truck is doing just as I stated. I use gas from known stores not small shops. I tried to post video but I’m afraid it won’t allow us to hear it. I’ll try it. No codes, truck has only 18,700 miles. Now truck is also making a loud pop noise when coming to a stop, and second dealer said that was completely normal. I called Chrysler/Dodge Cares and the case manager assigned to me was was rude and told me to keep taking it back, that a case can’t be opened without having truck in the shop. She lied because another employee there gave me a case # 71540abc, when I pointed this out to her, she got mad and told me I’m not a tech, keep taking it back.
It seems Dodge has no respect for there customers.

Chase300, I know it doesn’t make sense. However you know exactly what wrong with your car, because it is your car. Same scenario here, I know this truck because I drive it daily the engine will rattle/vibrate at any given time while pressing gas/ and even just coasting along road. Both dealers are giving me run around and doing there job incorrectly. The truck has also turned off while running on my wife, lucky road was not cluttered with traffic. The truck did start back up however.

 

So what happens if you floor it from a stop to say 80 mph?
Do you have the rattle at full throttle? Does the engine continue to pull strong? Should pull harder as revs pass 4K to redline.
Is the issue more while cruising at a steady speed? or when coming to a stop?
The stall is worrisome. Has me thinking trans related...assuming engine is performing properly.

 

Chase300, honestly I don’t drive truck that hard, the truck rattles at certain times, but when it does rattle and you push harder the noise gets louder getting louder then stops. You also feel it losing power, the rattle/vibration is what you feel. Sometimes I’ll be cruising , (not cruise control) and boom the rattle is going on, then goes away. The part that worries me, it that it did turn off while driving. This is wife’s daily driver, and she uses it daily. I would like to keep it but, Dodge so far has been very unprofessional. A co-worker said that he has a tech friend that works for Dodge. That tech told him that it was engine shifting to ECO MODE. However, the rattles still goes on whether eco mode is on or off. So I don’t know what the problem is.
Last but not least, now every time I come to a stop you can hear a loud pop noise coming from engine bottom area. Dealer said it was normal, that is why I’m asking because I never had a dodge and was wondering if this is all normal with these brand?

 

I know you mentioned you have tried 89 octane, is the engine sounding like it's got marbles inside hitting each other when it happens ? It really sounds from your description that she could be pinging badly.
Do you have 93 octane available ? i know the 6 is supposed to run on 87 or 89, i dont remember. if you're close to empty just fill her up with 93 it won't hurt anything. The more 93 you run in the tank the best.Then see how she does with that octane as a test. I run 91 in mine, but i also have my own tune.

Since you're testing, put the vehicle on rhino ramps go underneath and hit your cats with your hands (make sure they're not hot) and see if you can hear them rattling. they should not make a single noise other than your hand hitting the metal. they should not rattle or sound weird inside.

I'd suggest you to buy some tools so you can make your own diagnostics and see some engine vitals as well.
I use this stuff with an Android table and also from my Android Phone

With the V6, I would occasionally get a knocking noise from engine but no loss of power. Just as you would get from pre-ignition from low octane or carbon buildup. It would happen under light acceleration in ECO mode. It would go away if you applied more or less throttle. I just assumed it was receiving an incorrect fuel/air mix under certain conditions. I have never experience a popping noise when coming to a stop. That sounds like a suspension issue.

 

Mr G, thanks your reply is appreciated. I only add gas from big brand stores, such as HEB, Walmart, Shell. What did you do with Durango? The pop sound , dealer said it was completely normal.

 

I never addressed the knock in the Durango as it's only sporadic and goes away with a change in throttle position. I'm not particular with gas and currently fill at Valero, VP racing Fuels, Tesoro and occasionally at Costco. The pop you are experiencing is not normal. Could be suspension/brake/steering component issue. It sounds like something is binding/loading up on braking and then unloads when reaching a stop, hence the popping noise.
