What owners wrote
Speedometer sticking and going crazy ,cluster lighting in/out then gauges stopped working then whole cluster shorted and had dash fire.
Upon purchasing the vehicle I noticed prior to purchase that the fuel gauge did not read accuratly. The dealership agreed to reimburse me for the cost of the fix. After a day or two durring a short in town drive I noticed my speedometer was acting "jerky". I arrived at my destination, but when I left the speedometer was reading 60MPH at a stop. At what I estimated to be 65MPH the speedometer read 120MPH.
