Vehicles sold under the Chrysler family of brands have acquired a reputation for frequent electrical faults. This includes vehicles sold by Dodge and Jeep as well. Porsche and Mercedes-Benz vehicles also have a high rate of electrical issues.
Five Dodge, Jeep and Chrysler cars and trucks are featured on the CarComplaints.com list of the top 20 worst cars for reliability, as of 2015, with a large portion of these complaints directed against the electrical systems of these vehicles. Chrysler has issued a number of recalls relating to electrical components, including a recall issued in 2014 that affected nearly 900,000 vehicles with faulty alternators and defective power mirror wiring that posed a fire hazard. Many of the Mercedes-Benz models most prone to electrical issues were produced during the years of the Daimler-Chrysler partnership, during which both companies shared technologies.
One explanation for the electrical problems in the Porsche and Mercedes-Benz brands is that modern luxury vehicles have far more electrical systems than less expensive cars, leading to a greater opportunity for problems to occur. Much of the reputation of these brands was established due to earlier iterations of their vehicles, which had far fewer electrical systems as compared to modern cars.
