Tesla Inc.’s Model 3 sedan and a Fiat Chrysler Automobiles NV’s luxury sedan were among six vehicles from U.S. and overseas car makers that have lost Consumer Reports’ “recommended” rating due to their “declining reliability,” the nonprofit consumer advocacy organization said Thursday.

Tesla TSLA, -5.59% Model 3 owners told Consumer Reports that problems included loose body trim and glass defects, the organization said. Owners of Fiat Chrysler’s FCAU, +1.43% Chrysler 300 faulted the sedan for problems with the in-car electronics and transmission, Consumer Reports said.

The reliability issues “contributed to both brands tumbling 11 spots in CR’s latest car brand rankings,” the most in the lineup, Consumer Reports said.

Both Tesla and Fiat Chrysler, which also had its midsize sedan Dodge Charger in the list, said they already have addressed the issues raised by Consumer Reports.

“The 2019 Chrysler 300 and Dodge Charger represent the best iteration of the vehicles ever. We encourage people to experience the 300 and Charger for themselves,” a Fiat Chrysler spokesperson said. “With the improvements we’ve made, we’re confident 300 and Charger will regain their recommended status in the future.”

Tesla pointed out to a Consumer Reports survey that rated the Model 3 as the No. 1 “most satisfying car” and other accolades from the organization over the years.

“We’re setting an extremely high bar for Model 3,” and the company’s return policy allows any customer unhappy with their car to return it for a full refund, a Tesla spokesperson said. “Not only are our cars the safest and best performing vehicles available today, but we take feedback from our customers very seriously and quickly implement improvements any time we hear about issues.”

Tesla and Consumer Reports have had a fraught relationship, and the ups and downs have included the magazine’s rating the Model S as its top-rated luxury sedan in 2017 only to be dropped to “below average” in the ranking and losing its ‘recommended’ status last year. The Model 3 had received a recommendation from the organization in June.

Honda Motor Co. Ltd.’s 7267, -2.81% Acura RDX SUV, BMW AG’s BMW, +2.44% BMW 5 Series, and Volkswagen AG’s VOW, +2.06% compact SUV Tiguan also lost the recommendation.

“Predicted reliability is a key element in CR’s overall score,” the organization said. Consumer Reports factors in a vehicle’s performance in its road tests; reliability and owner satisfaction ratings drawn from a survey, the inclusion of some advance driver-assisted systems; and, if available, results from government and insurance-industry crash tests, the organization said.

“Only vehicles with the highest overall scores in their category” earn the ’recommended’ rating, Consumer Reports said.

“Consumers expect their cars to last and not be in the repair shop. That’s why reliability is so important,” Consumer Reports’ senior director of automotive testing Jake Fisher said in a statement.

“Our predictions are not a guarantee that any individual model will be reliable, but we believe that consumers who chose vehicles with a higher rating will be less likely to experience serious issues with their car,” Fisher said.
