We started noticing a musty smell coming from our vents. The smell is only present when the vents are on. It is horrible. We took the van to the dealership where we always have it serviced. They want $110 just to see where the problem is. I am not the only one who has this problem, they need to recall the parts that are causing this problem and fix it. I will never buy dodge again. Way to many problems!!!!!! And they fight tooth and nail not to fix their own poorly engineered vehicles!!!!
We have a 2005 Grand Caravan SE. A musty odor comes out of the air vents when the AC is on. Noticed it start over the last month. Appears that there is no cabin filter so looking for a solution to eliminate the odor.
Same problem, with musty odor, smells like urine when AC is first turned on.
Just started this summer 2011. Where is the AC exit pipe???

When turning on the blower, heater or AC, smell coming from the vents was like manure.

Took the van to the dealer and they could not find the problem. They put a refresher into the system which lessened the smell, but did not completely eliminate it. It's now wait and see.
Musty smell whenever the A/C units starts and from the drivers door when the window is opened.
Every time we get into the van my husband starts sneezing. He has said for years that the vents blow moldy smells.
whenever the air or heat is turned on - the smell coming from the vents is very musty and does not go away unless you turn off the fan. Tried all kinds of car air freshner to no avail.
Not fixed yet - but was advised that it's a mold issue and there is a spray you can purchase at an auto parts store and it stops the mold and keeps it from coming back.
Had a 2015 Journey and traded that POS because of all the problems unfortunately I was stupid and bought a 2016 Grand Caravan. If you have ran the A/C at all and then park for the night or you have been running the A/C and turn it off and run just the fan it absolutely smells like _hit for quite a long time. I also have a hot rubber hose smell when van is at operating temperature and I have the fan on A/C or no A/C. This is two of several issues but I have a sensitive sense of smell so this problem is the worse. I would rather have the Journey back.
Oct 19, 2015 We bought a new Dodge Grand Caravan from Sahara Dodge, in Las Vegas, NV

A few days after we bought the car, the car died at a 7/11 store. It wouldn't start at all. I called roadside service; all they checked was the battery and then told me to call a tow truck to have the car towed to the dealer. I called for a tow. About 20 minutes later I was able to start the car so I cancelled the tow truck. I took the car to Sahara Dodge. They checked and had the anti-theft device adjusted so it wasn't so sensitive. When I took possession of the car I turned the car on with the door open and the anti-theft alarm went off. I didn't have time to address that problem that day, because I had to pick my husband up from work. That same evening, the car was still running when I opened the driver side door, the alarm went off. My husband was there for this event.

Nov 10, 2015, I was driving the car to a doctor's appointment. No problem on the way there, but when I was on my way home the alarm started going off again. It would go on making one alarm noise, when that noise quit, another alarm noise started up. This went on for 20 minutes. I wrote down all the different noises it was making while I was driving it and headed to Sahara Dodge. When I pulled in to the dealer and got in line, the alarm went off just a worker came to my window. I brought his attention to the alarm and said that was my problem. I pulled up to where he told me to and went inside to let them know what the problem was. I spoke to the manager. I showed him the log of noises I wrote down from this incident and told him I wanted the anti-theft alarm removed and to reimbursement me for the $299. A couple hours later he told me the alarm had been disabled. I asked about paperwork and he told me there was no paperwork and he would call Chrysler Capital and tell them to take the $299 from my loan. This turned out to be a lie, my loan was never changed, and because there was not paperwork that changed hands, I had no paper trail to prove any of this.

Apr/May 2016, it got hot enough in Las Vegas to need the air conditioner on. That's when the smell of mold became terrible in the car. We took the car in on 6 May 2016 and told them about the problem. That's when they said they'd never heard of such a problem. They replaced the air filter at our request. That of course did not fix the problem. At that point I googled the problem on-line and found out it was a problem and Dodge had issued instructions for fixing it. I printed out everything on-line there was on the problem and the fix and my husband took the car in a second time for this problem, showed them what we found on-line and requested them to fix it. That was on 27 Sep 2016. Again they were denying the probem. My husband asked to speak to the manager. A woman came out looked at what we had printed. Said she'd never heard of this either. But, she said they would spray where the problem was supposed to be and clean up the mold. However, she ended by saying, if the problem still persisted after this, there was nothing else they would do to fix the problem. And again, we were told there was not paperwork we needed to sign. Again, there's no paper trail to follow. These are quite dishonest business practices from Sahara Dodge.

Since there's no paper trail, Sahara Dodge, I'm sure, will deny it all. I expect no less from a dishonestly run business.

Now it's May 3, 2017 and the smell is back. What am I supposed to do now? My husband has asthma and is breathing in this mold daily. While I don't have asthma, I do know that breathing in this mold can cause bad lung problems. A woman at work breathed in mold from air ducts that were not being cleaned. She got a horrible lung infection and was out of work for few weeks. I can probably pay to have someone else clean the system up, but that is going to cost a lot. Since you acknowledge the problem, I believe it is Dodge's responsibility to fix this problem.

We would like the air conditioning and heating system replaced at the very least. If they can't to that properly, give me a different car. It doesn't have to be a brand new car, but we'd want now less than a 2015 Dodge Grand Caravan to replace my 2015 Dodge Grand Caravan.

I hope you can help us with this problem.

Thank You,

John & Karen Beam
I havent had a chance to fix it but it gives me a headache as soon as I turn heater onfast and it does not go away it seems to get worse as it gets hotter . Looking to fix it I will let you no
I just bought the van used. I inspected the car before I bought it and turned on the A/C and heat. There was a slight smell but it wasn't anything I would consider out of the ordinary for a 10-year old used family van. thirty miles into the trip home, the A/C was on and smelled very moldy, similar to an old motel room.
