Toyota and Lexus dashboard may not show speed or warnings medium
When these Toyota and Lexus vehicles start up, a software error can leave the instrument panel, the display behind the steering wheel, missing important information. Your speed may not appear, and the warning lights for the brake system and for low tire pressure may not light up. That means you would not know how fast you are going, or that the brakes or tires need attention. Most vehicles get a free software update sent to the car wirelessly.
