Well this is probably going to be my last update. They 'think' they fixed it by replacing the ECM. I continued on with the Lawyer. Infiniti had me bring the car in to have a regional technician look at it. I was there maybe a half hour and since the car was working at that time all he did was check for codes and wrote his report that the car wasn't broke at the time - no kidding.

About a week later they sent over an offer to pay me $3500 but that the warranty on the ECM would be null and void. We told them no. And a few days after this the navigation screen went blank and wouldn't come back on - so there are definitely still issues. Infiniti couldn't find anything wrong with the screen because if the car sits long enough it starts to work again and they said it had to be broken when I brought it in....

The Lawyer had me fill out a BBB online complaint. Apparently that worked. Friday we received this email from Nissan USA:

Good morning,

I hope this email finds you well!

Nissan carefully considered your request during a review of all available facts pertaining to your clients situation. Based on the vehicle repair history, Nissan offers to voluntarily repurchase your client’s vehicle.

In order to coordinate the replacement or repurchase, Nissan needs to know the particular facts pertaining to the ownership and intentions regarding the vehicle. Please return the following documents to me at your convenience, as it will be needed to make a detailed offer:

· 5 Vehicle photos (4 exterior sides photos and 1 interior photo)
· Legible copy of the vehicle’s registration

We anticipate completing the replacement or repurchase within 2 to 4 weeks from the time you accept an offer.


I sent the pictures to the lawyer over the weekend. So my saga is almost over. I'm not sure what they are going to offer to buy this back, I would assume what I paid to date, but I guess we'll find out. It's kind of a shame as I like the car, I just can't trust taking it any distance.

Did you ever purchase another push button to see if the problems don't come back? How long did you run with the push button before it started acting up? I'd offer to send you mine to try but it's my wife's daily driver and a big inconvenience for her since she would have to dig around her purse just to try to find her key fob among god knows what else she keeps in that seemingly bottomless thing.

Hello tt6 Mine is a 2017 AWD with all the tech options (same as yours) I've never experience the display black out either...... as I said I am almost sure that the push button I got was defective and was making it go crazy......
I will try later on a new one and see how it does. at this point there is no doubt that the problem was the button, since I am not using it almost 3 months never an issue when it was on, issues almost every day

 

[tt6]

Glad that the Lemon Law served it's purpose for you! What happens to the cars that are repurchased under this law? Hopefully they don't just turn it around and re-sell it...?

What car are you considering to replace it?

LOL!! No worries about sending me yours =) thanks though
No, I have not tried another one, just waiting to get one from Mercedes directly and see......

I have had this occur before and the dealer had me turn the car off and then back on and it went away. However, recently I was exiting the driveway at my office and the car did what you describe--I pushed the gas pedal and nothing happened. I got concerned about pushing too hard. I turned off the car and restarted it and then it worked. This car seems to have these weird issues that the dealers are not able to figure out.

 

[rondief]

I was wondering if anyone is still experiencing issues?

My 2018 QX30 with 22K miles is experiencing the same VDC warning lights and lag in acceleration. I actually showed the dealer this post and they are starting by replacing the gas pedal sensor, if that doesn't fix it they are planning to replace the ECM unit.

is there anything else that would be causing the issue or do either (or both) of these seem to be the fix?

Thanks in advance, Ron

I can't comment on YOUR vehicle.

The gas pedal sensor was not an issue for MY QX30... Did they explain WHY they are replacing the sensor? MAYBE it's a problem for your car... But I haven't heard of that being an issue on any others (and it wasn't for me) so it does raise the question, in my mind.

If your dealer is simply shotgunning parts at your QX30 then I would RUN away from that dealership! Many techs are just parts-changers -- and they're fine for replacing brake pads or other "simple" repairs... But you do NOT want them handling the diagnosis of complex issues. Replacing parts that don't need replacement is a great way to waste time, and introduce further problems.

The dealer should be able to pull historical codes from the ECU. Ask them for a copy of that information. My dealer happily provided a list of all the systems and DTCs that were stored. After the dealer has the DTCs they should be checking on Infiniti Tech-Info for TSBs and other related information. They should then escalate to Infiniti Tech-Line for further analysis/guidance. Did your dealer advise that Tech-Line has become involved?

 

[rondief]

They did pull the codes. I did not see the list but I didn’t ask for it either. One of the codes was related to the gas pedal and one was related to the ECM unit. And actually I did not say anything about the gas pedal sensor but I’m guessing they are starting with that first since the ECM unit is over $1000.

At this point I have no reason to doubt my Infiniti dealer. This is my first trip here and we’ll see how it goes.

You guys may want to check out the MB CLA forum. Some people had this issue as far back as 2014. I can't say it's related for sure, but
it is a Benz/Infiniti combination vehicle. I recall the gas pedal and wiring harness being issues. Best of luck!

 

[rondief]

Thank you!

Similar problems started with my QX30 (at 11,000 miles) two weeks ago with the vdc lights and with an emergency brake inop warning multiple times. Dealer checked the codes and replaced the accelerator pedal. 10 miles later, the lights were back on and the car was back at Infiniti. There were new codes in the hopper but I have not heard anything yet.

Here's the lowdown two weeks later. Tech Support said to replace the ECM, but that did not clear out the codes. The next step was to replace the wires between the accelerator and the ECM. So far seems to have worked.

I had the same issue. They replaced the gas pedal sensor nap helped for about two weeks then the lights returned and so did the codes. They replaced my ECM unit several weeks ago and seems to fix the problem. Hope everything works out for you

 

[denny]

Had meet the same issue. I pulled off and restart my car and the codes just gone. After that it never happen again and hope it won’t as well in the future.

 

[alexmed2002]

Hi everyone, I just had the same issue today while driving to the beach in my mother's 2018 QX30. I was going around 40 MPH when I got the Traction Control Inoperative error message on my cluster today. The transmission went into limp mode, and it felt terrible to say the least. I'm going to be keeping an eye on the car, but should I be worried? It didn't come back after I restarted the car.

 

[alexmed2002]

Welp funny enough I return to this subject. The other day this happened to us 3 times in one day!!! Now the check engine light won't go off. We're having the car towed from our home to the Infiniti dealership we bought our QX30 from. The car is at just over 19,000 miles and we are already having issues with our car. I really hope it isn't a lemon .

 

[alexmed2002]

We got our car back today. It drove fine. I really hope the ECM doesn't crap itself later down the road. I wrote what the Invoice we got from the dealership said below.

This is what the Invoice said:
"Confirmed light on with codes P2138 for the throttle position sensor. Completed inspection of the terminal connectors between the accelerator pedal throttle sensor and the ECM. Found pins 4 and 5 at the throttle sensor to have loose fit. Replaced the connector and terminals at the throttle sensor for better connection. Cleared the codes and test drove for 25 miles to confirm the light is off and it is now running normally".

Hi! I leased my QX30 in February 2017, and have had no problems, but as of a few weeks ago, the light that look like a swerving car, and the light that looks like a swerving car with "off" below it (attached in photo) have come on at random times as well as the message "inoperative see operators manual", usually when I am driving in city/stop-and-go traffic. This results in my accelerator acting strange, as I have to push harder on the gas to go forward, and when it finally starts to move it jolts ahead aggressively. Last night, the check engine light also came on which has me very worried. I plan on taking it in to the dealership tomorrow but was curious if anyone else was having this issue. Thanks!

Did you get this issue resolved? What was the solution?

 

[alexmed2002]

Did you get this issue resolved? What was the solution?

If you haven't already, check my posts that I made earlier in this thread. I had the same problem and it ended up being the wiring between the accelerator pedal throttle sensor and the ECM. According to the dealer a couple of the pins in the wiring near the throttle sensor were loose, so they replaced the harness.

 

[Walt]

Did the inoperative mode leave a code that the dealership could see. My service dealership said they can't service anything If they don't pull a code up.
