While accelerating to get on the parkway my car locked at 7000 rpm's and continued to accelerate with my foot off the accelerator. i was forced to put the car in neutral to avoid an accident, if i were not an experienced driver this could have caused a fatality in the car was at 80 mph and quickly rising. the tachometer continued at 7000 rpm for roughly 20 seconds, only after continually tapping the accelerator it finally began to decline. please look into this life threatening situation. additionally my tire pressure light remains on even when all tires are at the factory recommended settings. *tr
