I have a 2022 Stelvio Veloce delivered on 2/20/22. Two weeks after the check engine light came on....been to back and forth to the dealership (1 hour away) and they can't fix it. Said it needs a "software" update. In the mean time, it drives completely different. Check engine light disables the start/stop and the dna knob is disabled. So disappointed in the purchase and their inability to resolve the problem.
Similar for my Veloce.
Built on 1/11/2022.
This Saturday, driving around, the CEL kicked on, the Stop&Start Unavailable light flipped on, the Service Electronic Throttle Control Light on, and the Service Engine message on the display. DNA modes locked into N.
First thing I did when I got home was tested the battery. 12.82 volts at the battery terminals after sitting for 4 hours.
Tested the battery voltage at the under hood jump points, and it was 12.71 volts there, so the battery IS NOT the issue in my case.
When I fired up the engine, the idle speed was hunting wildly, with sudden jumps and drops between 1500 and 2800.
When I drove the car, and it got fully warmed up, engine speed is nice and stable around 800 rpms in neutral.
To me, it sounds like an unmetered air leak past the throttle body somewhere, but it doesn't happen when warmed up, which is odd.
If its leaking air, it should happen, warm or cold.
Warnings are on as soon as key on, engine off, so they are not going away on their own.
Called up the dealer this morning, and he said that there was a new TSB and flash released just 2 weeks back, that should cover this situation.
So then I got to pull up the Alfa roadside assistance website, and request a tow to the dealer, because I'm not driving it 50 miles in stop and go highway traffic, in case it decides to drop into limp mode, or takes out the engine running way too lean if it is in fact an unmetered air leak.
After a couple of calls back and forth with the towing company (note that I DID NOT call Alfa Roadside Assistance), instead of them showing up at 1:52 pm to pick up the car, they arrived at 3:50 pm to pick up the car. I called my dealer a couple of times to let him know about my issues with the tow company, and let them know when they actually did pick up the car, and start heading their way. The dealer was nice enough to call me back when the car arrived at their service lot exactly an hour later, which was amazing time, considering it was heading into rush hour here in Denver when he took off.
So, hopefully I will get a call tomorrow afternoon, telling me that my Stelvio is all fixed up, and ready to be picked up.
