Fiat Chrysler Automobiles ( FCAU ) has quietly paused production on its hybrid Pacifica minivan in recent weeks due to a recall of the vehicle amid technical issues, sources told The Wall Street Journal. The delay is irritating buyers of the 84-miles-per-gallon hybrid gas-electric vehicle. "The most information I can get is that it is being audited for safety," Maryland car buyer David Pittman, who ordered a hybrid Pacifica in April, told the paper. The production problems are a "black eye" for the company, Fredonia, N.Y., Chrysler dealership manager Bill Bernard told the Journal. "Chrysler does a very poor job of launching new products." The paper noted that the model's customers include Alphabet's Google ( GOOGL ) unit, which has been using some 100 hybrid Pacificas -- and ordered 500 more -- to test self-driving-car systems.
