While modern automakers like to say that they’re mobility providers, not just engineers, it is still central to the automotive experience that a car be able to accelerate and decelerate. For the 2017-2018 Alfa Romeo Giulia and Giulia Quadrifoglio, the first half of that equation may not be a sure thing.The National Highway Traffic Safety Administration (NHTSA) has opened a preliminary evaluation to look into customer complaints that the fuel pumps on the sedans are failing, leaving them without the ability to drive forward.NHTSA says that it has received 12 complaints from customers, and multiple field reports alleging that 2017-2018 Giulias have lost motive power or stalled while they were on the road.
