“2018 Giulia qv but it has been in the shop in pensacola for over 7 consecutive weeks and they still have not figured out what's wrong. Under acceleration and left hand turns the service electronic throttle lights up as well as various other lights. What's scary is the power steering temporarily stops, yanking the wheel hard right and I have to muscle it to keep it from running off the road. Nothing short or dangerous. I have had a case open with alfa cares and have tried to escalate with no result.”

“Service Engine and Service Electronic Throttle lights came on. The car/engine started shaking/stuttering pretty violently, so I quickly turned off the car. I waited about 2 minutes and started the car again, and same thing. I waited another 10-15 minutes to start the car again. This time, the car started fine without Service Electronic Throttle light, but Service Engine light was still on and the drive mode was stuck on N”

“My BCM was shorted out from water damage from outside the car. The dealer says he can't repair it under warranty because Alfa Romeo will not authorize him to. I have to pay 1200 out of pocket for something that should be covered by warranty. The car will start, but the front headlights won't go out, the turn signals won't work, brake lights don't work right. Check engine light comes off and several functions are disabled. I'm not sure the backup camera, blindspot monitoring are working correctly.”

“The climate control system has malfunctioned since I purchased the vehicle. Hot air blows out the driver's side regularly, and Alfa Romeo, and the dealership I acquired it from, j star motors in anaheim, ca., don't appear interested in correcting the problem, even after four visits. The issues is more of a comfort one, than a safety issue, but all the same, a recall might be in order. My contact at af has stated that she has dealt with this issue a number of times.”
