I have had 7 Infinitis in 10 years and, until my leasing a QX30 two years ago, have had great service and great performance. My QX30, however, has had repeated electrical problems (failure of the NAV screen while driving, headlamp problem resulting in a week in the shop, recall regarding steering column, etc.) After calling Infiniti to start a Lemon Law Case, I was advised by the customer service rep, "yeah, we have had some problems with that car." In spite of reviewing the voluminous service records, Infiniti is not letting me out of my lease, even to get another Infiniti. I would be interested in hearing from other QX30 owners who have had problems and how they have been dealt with.

Overall, I can't complain.

Infiniti notified me of a recall/TSB to rectify a potential ground issue that may result in inadvertent airbag deployment. We discovered that the "fix" required puncturing holes in the steering wheel cover, and that the marks were permanent. We objected, and the dealer contacted Infiniti corporate, who authorized replacing the steering wheel. It took a couple weeks to get the parts.

We experienced a loss of AWD function when it rained. This was a big concern for me, as AWD was an important feature. We took it to the dealer twice. The first time it was dry and they said they couldn't reproduce it. After the problem re-occurred we took pictures of the warning lights, and we took it back to the dealer. We were polite, but insisted that the issue needed to be addressed. The dealer gave us a QX70 loaner (nice) and agreed to keep the vehicle for several days. When we came back to pick it up, they had a thick stack of diagnostic paperwork, which they walked us through. They ended up spending considerable time with Infiniti tech line, and on their advice replaced the ECU. We haven't had the problem re-occur.

We have an intermittent issue where the backup camera sometimes does not display -- the screen stays black. We haven't asked the dealer to look at this, yet.

So, I empathize that this vehicle can have some issues. I half-expected some of this when I bought it, knowing that it is mechanically a Mercedes GLA with an Infiniti infotainment system retrofit inside. So you end up with a product that has the problems of both platforms, plus some new issues introduced by the integration. However, I must commend Infiniti and our local dealer. They've done a good job taking care of us.

I had my steering wheel replaced also after the recall bulletin was accomplished and it took some persistence...but as soon as BBB was involved, the speed picked up and they agreed to replace.

I have had my alternator replaced due to a couple battery warnings on the dash and when they replaced it, they didn't completely tighten a ground...which later came loose and caused the junction box to melt. (but that was a dealer repair issue more than a mercedes / infiniti issue.

Otherwise, it has been very reliable and efficient and I still enjoy driving it quite a bit. (add Dinan's Dinantronics if you want a bit more HP and torque)

Luckily, no issues with the nav or screens or headlights (I did upgrade the halogens to LED)

Hope your issues get fixed.

having similar issues and all I hear is that they cannot duplicate the problems -- doors don't auto unlock, remote not recognized when starting car, cannot reconnect my phone after issues with auxillary plug; high beams go on in the daytime when I go over speed bumps or pull into my garage. Menu screen does not work -- cannot access "Settings" to reconnect my phone.
I think there are electrical issues and the dash components need to be replaced but trying to find someone who knows what they are doing with these cars is frustrating.

yes, I am having similar issues. My car has been at the dealership 5x since I purchased it in January 2018. They can't duplicate the problems. I am driving a loaner -- QX50 -- I have not had one problem with this car -- it unlocks, I programmed my phone in 2 minutes, the high beams don't go on when I drive over speed bumps and it always recognizes the remote when I start the car!!!
I have sent videos of the issues, but they can't duplicate the problems. Today I was advised that my remote doesn't work some times because it goes into "Hibernation". Never heard of such a thing!

I purchased my QX30 two months ago. Approximately 6 weeks after owning it I released the rear hatch cover to vacuum only to discover the left harness was crushed. The next day I went to the dealership and asked to have the part replaced. When I went in for my follow-up appointment for another problem I was told the cover itself couldn't be replaced, the entire wiring harness had to be done as well and the dealership wasn't authorized to do that since it was an $11,000 repair. The dealership contacted Infiniti and the request was denied.
I then contacted Infiniti Consumer Affairs. Spoke to a regional manager who told me since I haven't had any problems "yet" with the electrical system they can't and won't do anything about it. She also said while my case has been documented she can't guarantee that if these problems don't occur until after the warranty expires, that Infiniti will be willing to assist me.

The major problem is from what I gather, everything electrical runs through that harness. The regional manager did say that every time the hatch is opened and closed those wires are getting pinched. She also said that even if/when they replace it, it will happen again. If it's crushed once, it's going to get crushed again.

I was told the only way something will be done is if enough people have this problem and complain to consumer affairs. IMHO it is a design flaw that Infiniti won't own up to.
