There are 4 owner-reported electrical system complaints for the 2019 Alfa Romeo Stelvioin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
My car stopped and would not turn back on while in the middle lane of a busy highway. We were stopped on the highway >20min until police arrived to block the lanes so we could safely exit the vehicle and a tow truck could safely retrieve it. The ground strap underneath the vehicle that grounds the main engine harness was broken. As a result the electrical short resulted in burning/melting of several spots on the harness. There was no warning ahead of time and I’ve learned that this is a known issue. We are very lucky that this did not lead to a crash, injury or death.
The vehicle has been in the shop since August 2025 attempting to be fixed. I have been making monthly payments and have not been offered any rental assistance or vehicle loaner assistance. My vehicle has multiple safety recalls and no current remedy.
A corroded faulty ground strap under the car, which is connected to the transmission caused the engine wiring harness to overload a smaller ground wire in the wheel well, then continued to melt other sections of the main engine wiring harness when trying to start the car. This is only a $200 part, but caused $6k+ of damages calling for a labor intensive job of replacing the entire engine wiring harness. The manufacturer does not provide any information on this to the owner as a maintenance issue or something to keep an eye on to prevent this issue. It's obviously a defect.
I PURCHASED MY CAR IN JAN. 2020. ON JUNE 21, 2020, I AWOKE TO MY ALARM GOING OFF. I TRIED TO USE MY KEY FOB TO TURN THAT ALARM OFF AND IT DID. NOT WORK. THE ALARM STOPPED AND I HAD TO USE THE HARD KEY TO ENTER MY CAR. THE CAR WOULD NOT START AND I HAD TO GET A JUMP FROM AAA. THE CAR WAS NEW WITH LESS THAN 3000 MILES ON IT. I TOOK IT TO THE DEALER TO FOR A DIAGNOSTIC AND THEY KEPT IT FOR 5 DAYS. THEY HAD TO REPLACE THE BCM. THE BCM WAS LISTED AS PROBLEM IN PRIOR YEAR VERSIONS OF THIS VEHICLE. THIS APPEARS TO BE A CONTINUING PROBLEM WITH THIS VEHICLE. THE VEHICLE WAS PARKED AND WAS NOT BEING DISTURBED WHEN THE ALARM WENT OFF.
