Good evening gentleman,

I just purchased a 2017 qx30 with 25k mileage on it from a used car dealership, very few dings and scratches, overall great condition. I noticed few things, wanted to ask you guys what you thought.

1. There's a tubing that attaches to NOTHING(see circle blue, one end & the other end), very strange. Does anyone know what's going on here? [dealer had no clue]

2. The rubber sleeve isn't covering the end all the way(see circle red), is that normal/okay?

3. Did anyone replace the tires with non-run flat tires? If so, how was the ride quality?

4. Unfortunately, dealers had one key total, has anyone paid for a second, if so, how much did you pay? (stealership vs independent)

5. When your car is running on highway/local, on the engine temperature gauge, are your levels usually at 50%? i noticed mine to be around 70%.

Thank you for all your inputs and help.

1. That looks like it might be the vent tube for the battery. You should re-connect that.


2. That's fine. The rubber sheath is just to prevent chafing. As long as nothing is rubbing against the wiring, you're fine.


3. I haven't. These vehicles don't have spare tires, so I think run flats are a good idea. I think it rides well, for what it is.


4. They're not cheap. It would have been wise to negotiate a 2nd key as part of your deal.


5. Yes, that's normal.

We bought a 17 with 18,000 miles on it not that long ago. One key came with my wife's car as well. The key fob was supposed to cost $220 and programming $95. They had trouble programming the key. They had to order a second key fob and went back and forth with the engineers for ten days. Because of the length of time it took to get us two working keys, they knocked off a chunk of change. The SA at Infiniti of Marin said normally it takes an hour, due to it being a MB key fob, which is longer than doing any Infiniti key fob. This was unusual. You may want to call around and get a good price, and have your dealership of choice match it. That's what I did.

I bought my ‘17 QX30 w/ 28K miles from a Buick dealers’ pre-owned lot. It only had one key fob but the dealer, without me asking, said he would get me a second from the Infiniti dealer (not same dealership owner). Got the second key back, programmed, at no extra cost. He showed me the Infiniti invoice and it was around $300 for the key & programming!

Thank your detailed response! I bought it from a Hertz so it was very difficult to negotiate the 2nd key fob, I really tried too. Had to push them to even replace 1/4 tires, they wouldn't budge on covering anything else.

****So I'm getting super nervous about the tube******
I looked at my battery (see attached, do you guys have the same battery???) and I don't see a battery vent tube insert point, and in addition, I'm not sure where the other end of the tube would attach to. Is it possible to see if you gentlemen have the same tube on your engine tube and where it attaches to?

That’s not the factory battery. Explains why the vent tube was disconnected. Not all aftermarket batteries have vent tubes. That looks like it’s probably a cheap lead-acid battery. If so, then I’d expect you’ll kill it quickly. These cars come with AGM batteries for a reason.

I would have encouraged you not to buy a car from Hertz. But live and learn. If a battery and FOB are the worst you have to deal with, then it’s not the worst of lessons.

Good for you! I tried my best to get John L. Sullivan Chevrolet in Roseville to give us a second key fob, to no avail.

Thank you
You're absolutely right, a friend of mine has a qx30 rental from enterprise, I looked under the hood and found that it has the OEM car battery with the tubing. These retards must have put inferior lead-acid battery in.

Seems like Infiniti/Mercedes uses a protective plate under the battery using an adhesive as well. Geez...all I am thinking about is dollar signs lol :crying::crying:

Do you know how much an OEM battery costs / protective plate costs?

 

[p07r0457]

I wouldn't necessarily bother putting another OEM battery in... However, you can get an Interstate AGM battery, such as the MTX-458 H6 for ~$200.


Our cars actually have two batteries... The second is a smaller "auxiliary" battery that is inside the cabin, under the dash, by the passengers feet. You may want to double check that you still have that battery present and see if it's the OEM one.


As for the "protective plate", I'm not sure which part you're needing (if any). Some batteries have a plastic spacer that is only needed to fill a gap so the battery doesn't move around. Or are you referring to something more?


The parts catalog lists these items that might be what you're talking about:


Support Assembly - Battery

648605DA1A
$102.42


Bracket Assembly - Battery Mounting
648615DA0A
$54.51


Bracket Assembly - Battery Mounting
648605DA0A
$160.38


Bracket Assembly - Battery Mounting
648605DA0B
$125.35


Bracket - Battery Mounting
648665DA0C
$9.84

I will definitely check tomorrow if the vehicle ATLEAST has the OEM auxillary battery, i hope it does. Definitely frustrating.

The protective plate is labeled as:

Support Assembly - Battery
648605DA1A
$102.42

I see on the owners manual that they recommend replacing that part when replacing the battery, is it absolutely necessary? As I never had a vehicle with an AGM nor Support Panel/Protective Plate under the battery.

Furthermore, would the car have to be reprogrammed at the dealership after the battery replacement?

Thank you again!

It appears that plate may be protection against punctures in a crash. Your call if you want it, or not. Clearly Infiniti felt strongly enough to include it -- and it is a safety-related part -- so I'd personally want to have it... But it shouldn't affect the operation, in day-to-day driving.

As for as "reprogramming" with a battery replacement: no, there is none required. The service manual does include some systems that they recommend inspecting, but I doubt any of them will actually have a problem, and personally I'd have no concern with a DIY battery replacement.

Do you happen to know if infiniti and/or mercedes sells:
1. The unlock button on the drivers door? My used car has a pretty big scratch on it

2. The small black fins on the lower passenger side of the front bumper (also with scratches)

Thanks again!

 

[p07r0457]

You mean the interior door lock/unlock buttons? Part number is 252105DA1A. MSRP is $74.13.

As for the "lower passenger fins" I'm guessing you're referring to the front bumper fascia finisher?
I also assume you have fog lights?
Part number is 622565DJ0A. MSRP is $139.42.

Thanks for all your help. I indeed have the fog lights. It blows my mind how expensive some of these parts are. Perhaps I will wait til there are used parts for sale LOL. Coming from a Honda Accord where parts are next to nothing, this blows my mind. I

Yep. Mercedes parts are already spendy. Then add a multiplier for the low-production-volume customizations Infiniti has made, and their profit on top... The QX30 is the least expensive Infiniti, to purchase, but certainly isn’t the least expensive to repair.

How sensitive is the Qx30 lock and unlock supposed to be when pressing the door handle from the outside?

It takes few attempts pushing/pressing on the small square on the door handle. Is that normal? Is there a way to adjust the sensitivity?

I will upload a video tomorrow explaining what I mean lol

Thank you

I agree. Sometimes it works the first try, sometimes not.

 

[p07r0457]

Drink more water? I believe it is a capacitive system, so you must conduct some electricity for it to work.

Personally, it's never given me any trouble, and works every time... But I always carry around a bottle of water (constantly hydrating) and I live in a humid climate.

It's gross, but as a test you could lick your finger and see if it improves the response. If it does, than that kinda confirms the theory.

 

[Parthur]

This system is different at the G35X I had previously....... on the QX30 I place my hand between the door and the handle (slight touch to the inside of the handle) and it unlocks; to lock I just touch the OUTSIDE of the handle on the square. It works every time.........

Does anyone happen to know how to install a factory front license plate bracket? Tried youtube if there are any prior videos on the white plastic parts that came with the bracket with no luck.
