Monday, I was out and about and decided to stop for coffee and a donut. As I pulled into a local place I noticed that the Start/Stop and Check Engine warning indicators were illuminated. I also noticed that the DNA selector wasn't working. Not wishing to get left on the side of the road, I went home and logged in to this site, knowing that the experience wasn't unique. I read everything that seemed relevant and tried out the suggested solutions. I started and stopped the engine multiple times, opened and closed the hood, etc. No joy. I even tried something that does a reset on my Mazda MX-5 ND after a change has been made - lock the vehicle and let it sit for 5 minutes. No good.

Having exhausted what I had hoped would solve the problem, I called the Service Dept. at the dealership, Essence Maserati/Alfa Romeo in Hurst, TX. They told me to bring it right in which I did. During the phone conversation the possibility that the battery was going toes up was mentioned. That had also occurred to me since it has been mentioned here more than once as a culprit. Anyway, the vehicle was taken in immediately when I arrived. After 30 or so minutes, the Service Writer came to me and said that the tech found a bad O2 sensor and, most importantly, he said they had the part in stock. Great, I thought. It can't take that long to remove and replace (R&R) the sensor and I'll be on my way in time to beat the rush hour traffic. Eh, not so fast, my friend.

When I walked out to the service area, my car was up on a lift! WTH! It turns out that to get access to do the R&R, the left front wheel had to be removed and part of the liner in the wheel well also needed to be taken off. Tick tock, tick tock. When everything was back together, the tech took a 15 mile test drive, came back and checked to make sure all codes were cleared and no new ones had popped up. All good. Unfortunately, the earlier 40 minute drive from home had now turned into a 90 minute return trip. Oh, well. The important thing for me was that the car was fixed.

I can't leave this without saying that the folks in the Service Department were friendly but totally professional. They kept me informed about the problem, the solution, and the timeline. This was my second good experience with them (earlier, the car needed a proxy alignment to clear flashing odometer display). Additionally, as I wandered around the facility away from the Service Dept., multiple staff asked politely if I was being taken care of, offered water, coffee, etc. and were just generally welcoming. Hopefully, I won't need to visit them again until my 10K mile service but if I do, I have confidence in them.

Sorry to hear it happened bluzman but glad to read how well the dealer took care of the problem and you in the process. Ideally, a vehicle that new should have no problems but we know that "stuff" happens. What was ideal is how promptly they got you into their schedule and got you back on the road. Kudos to Essence Maserati/Alfa Romeo of Hurst, TX.

I had the same issue a while ago, however my car stalled. This was at 13k miles. It also happened after a sudden brake failure a week prior to that.
Service performed update, no problems to report sonfar others than the brakes pedal pressure is wonky particularly at low speeds... car spend 2 weeks in service, this is about the 9th time my vehicle is in service for issues...

I am also struggeling with my check engine light. I have been into service a couple of times and they have been changing a few things, such as the throttle actuator. But the engine light has always been coming on a short time after.

The error code is P2172. Which error code did you get? The same one or a different one?

The next time that code comes up, ask them to replace the MAP sensor...it will more than likely fix your problem

Even though the car runs perfectly fine, is it still a possibility that there is a faulty MAP sensor?

 

[Crosshairs]

Its a possibility..I've seen it on other FCA cars..2172 is a high airflow code...loosely translated that means the ECU thinks the throttle body is passing an unusually large amount of air for the current operating conditions.... so in order to prevent a runaway, it limits the throttle blade actuation and turns the light on..one of the inputs to the ECU for this strategy is the MAP sensor..a sudden voltage drop translates into a sudden air increase ( sudden throttle blade opening ) because it's interpreted as low a vacuum condition.( vacuum leak)
on the early 2.4 FCA engines the MAP was subject to oil fouling... I have no knowledge that these engines have the same problem but that code is a tell tale that there may be MAP issue and its often times overlooked since there are no accompanying driveability concerns,

I had the MAP sensor changed the other day. Unfortunately that did not help. The check engine light came on after a short drive with the same error code, P2172. The light came on when I put the gear leaver in "P", which to me is a bit strange. That has been the case on the last two occassions when the check engine light has come on. How can that be?

Hi!

I appreciate your response and consideration to me as a customer. I live in Sweden and I am in touch with a local Alfa Romeo workshop about this matter. They have been taking good care of me, although the case is not solved yet. There is also an ongoing case with FCA technical support. But thanks again for your concern.

Hello, I have not had any issues with 2019 Ti sport Q4 with about 2200 miles. Yesterday, after a very pleasurable roughly 160 mile drive to Boston from a NYC suburb, I had my wife take the car for a local loop while I finished a doctors appointment. When she brought back the car 2 hours later (she had never driven it before yesterday) and I started the car, I noticed the start/stop will not function warning was on an when I started to drive noticed relatively no power and realized CHeck engine light was lit while the DNA selector was inoperable. I drove about 5 miles to a nearby restaurant and after a one hour lunch break, returned to the car we ping fingers crossed that would be ok for the long drive back to CT. On starting the car, was really happy to find everything back to normal. Before heading off, I searched the forum and noticed that your issues most resembled mine. This morning called Alfa service at Miller, the local Greenwich dealer and set up an appoint,met for next Tuesday (also plan to get the fuel gauge recall done).
My question, you reported a happy resolution to your issue following replacement of the O2 sensor——have you ever had a recurrence of this problem?

I read someone else on the forum opining that CEL coming on automatically disables auto stop/start and DNA, don’t know if this is accurate.

Has anyone else run into this problem?
Thanks!

There's been no reoccurence of the issue nor have there been any others.

 

[Red$torm1991]

Dealing with the Auto Stop Check engine light issue right now. so far the folks as Essence Alfa maserati in Husrt TX have been on top of things. they checked the code and in my case the starter harness was faulty. They have to order the part and i'm waiting on them to bring the car back for repair.

After my very recent purchase from the Hurst TX dealership, car would not start this morning but all the dash lights/radio/electronics seemed to work. After about 20 min of me just sitting in the car and on the phone with the dealership, I tried to start it and voila it started, but my check engine light/start stop lights came on and DNA is not working. Drove the car around for a while, stopped and started it again seems to be working but the dash lights are still on. Alfa Romeo Roadside assistance was completely useless...the girl on the phone kept on asking me for a policy#, mind you I told her the car was purchased 3 days ago...so I do not have any knowledge of a policy# ... Taking it back to dealer next week for brake job and for them to check/change the battery...

Thanks!

The problem you describe is one of the many engine faults I have had with my '17 Giulia Ti, many of which seem to self-correct after sitting overnight. Unfortunately, many of these self-correcting faults do not set a code, so the dealer cannot offer a specific correction - they usually check for any outstanding service items and/or give the computer a reflash. (Also unfortunately, unless there is a code and identifiable problem, it doesn't get listed as a "lemon" problem.)
I've also noted that the Start/Stop fault message shows and the DNA is disabled with most of the Check Engine Lights (CELs) - I'm told that the Start/Stop function is automatically disabled when some CELs go on to prevent you not being able to restart the car.

[DEEZZ]

This just happened to me. Start/Stop disabled, CEL, and a host of other warning lights and DNA doesn't work

It happened about a week ago, then the next morning the car was back to normal. I drove her hard that whole day and nothing happened.

Now, a week later, it just happened again. Going to make an appointment w/ the dealer tomorrow.

2017 Ti

EDIT: So all day I've been driving with the CEL. Then I checked the gas cap. I just took it off and put if back on. BINGO! No codes and DNA is working again.
