Vehicle owners' satisfaction with their insurers is at record levels despite steady increases in premium prices during the past five years, according to the J.D. Power 2014 U.S. Auto Insurance Study released Friday on Overall satisfaction with auto insurance companies increased by a significant 16 points to 810 on a 1,000-point scale in 2014, the highest since the study launched in 2000. The study measures customer satisfaction across five factors: interaction, price, policy offerings, billing and payment, and claims. While the percentage of customers experiencing an insurer-initiated premium increase is about even to last year, 19 percent versus 20 percent in 2013, the average increase of $86 was much lower than last year's average of $153. A J.D. Power executive credited more effective communication by insurers for improved satisfaction despite premium increases.
