The contact owns a 2011 Jeep Wrangler. The contact stated that while driving at an undisclosed speed, he heard an abnormal whistling sound emanating from the engine compartment, after which he observed smoke emanating from the engine compartment, prompting him to pill to the shoulder of the roadway. After a visual inspection, the contact observed that the smoke was originating with the alternator, which seemed to still be receiving power even though the vehicle was turned off, prompting the contact to disconnect the battery. Upon disconnecting the battery, the smoke dissipated. No warning lights were illuminated. The vehicle was taken to an independent mechanic, who had yet to diagnose the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 156,000.
I had just dropped my 6 year old off school, went to leave with my 7 month old and ended up stranded because the alternator went out, just to find out that there is a sensor in the computer and isn't something that can be fixed real quick. So now am in a major bind trying to get my family places while my Jeep sits.
