In 1956, during the design of the 1961 models, Exner suffered a heart attack. He resumed work in 1957, working on the designs for the 1962 cars. On July 25, 1957, Exner was elected the first vice president of styling at Chrysler. Unfortunately, a rumor that GM was reducing the size of their cars caused the president of Chrysler, Lester Lum ("Tex") Colbert, to order Exner to do the same to his 1962 design – a change Exner disagreed with, thinking it would make his cars "ugly." Exner with his associates had completed work on the second full-sized finless Plymouth since 1955, this one for 1962, described as a strikingly attractive automobile. While he was still recovering from the heart attack, the 1962 models Exner took credit for were downsized by associates. This downsizing drastically changed the cars' appearance. This reduced the cars' appeal and caused a significant drop in sales. It turned out that the Chevrolet rumor was false and consumers disliked the smaller Plymouth and Dodge cars introduced for 1962, the styling of which was bizarre compared to more sedate Ford and GM products. Needing a scapegoat, Chrysler fired Exner. He was allowed to retain a position as a consultant so he could retire with a pension at age 55. He was replaced by Elwood Engel, who had been lured from Ford. Engel was highly regarded for his design of the classic 1961 Lincoln Continental.
