Question: what makes my car's warning lights go wacky?

all of a sudden, my traction control light is on, then off, my oil light is on, then off, my gas guage shows no gas, then jumps up, the led headliner guage shows low for distance to drive and then jumps to 300km, then down to 240. what would likely be the cause of this seemingly electronic problem? Recently the engine light was on and a mechanic suggested after a diagnostic that I replace the gas cap as they wear out, so I did thinking it would be the cheapest way to possibly fix the issue. Could this be right?

Well, a gas cap is one of the hundreds of possible causes why a check engine light can come on--so it may be a valid suggestion if a scan of the diagnostic codes showed it was a problem--but there is no way that would cause any problems with your other gauges.

Because so many of your gauges and lights are involved, it is probably a problem with the dash unit itself, or the wiring to it. You'll have to have some further diagnostics done to isolate which one--but I don't recommend going back to the mechanic that suggested a gas cap.

Car Brakes: How Do You Know When to Change Them?

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
