Example complaints

“Driving down a straight road (thank goodness), no traffic close by, no overpass and going about 45mph. I heard what sounded like a shot gun in my car. I heard air and looked up and my sun roof was busted. No way anything hit it. I was on top of a bridge with no walkway and a river about 5 stories underneath. I was scared to death and my poor dog in the back is still traumatized. I pulled over and the sunroof was busted all around the edges and a big hole in the middle protruding out toward the sky (not inward like something hit it). You can see from the photos. …”

“I bought my 2018 Stelvio in dec 2017. I thought it was odd the car needed a software update only about three days after having it - now after researching I've learned many people have brought their new alfa romeos in for software updates related to all the sensors and electrical systems. My car currently has about 5k miles on it and in those miles I have experienced on about 3 or 4 occasions a warning message on my display that reads gear selector malfunction or automatic transmission failure . The message also tells me for both issues not to shift out of drive . …”

“I went to start my car to head to work and the car did not start so i tried to start it again all of a sudden smoke started billowing out from the engine bay. it scared me bad i thought the car was going to catch on fire. I proceeded to have the car towed to the dealer where i was told that a ground strap on the transmission has failed causing the wiring in the engine bay ti burn up. I'm still waiting on a estimate of how much it will cost to repair the vehicle. i believe this is also a safety issue the car could have easily caught fire or died at a stop light causing a crash or road hazard.”
