Suzuki Grand Vitara 2009: Power loss

With reference to the problem with the 2009 Kia Sorento in Carsguide on November 30 I had a similar sounding problem with a new Suzuki Grand Vitara a few years back. It would lose power at regular intervals, which was dangerous as well as frustrating. The dealer couldn't find the cause, but after a while I came to realise that it only happened when the radio was on. The service tech took the car for a drive with me and we put the radio on. When he tried to pull out into traffic the power dropped. He got the fright of his life. Turned out it was a wiring issue behind the dash.

Finding the cause of a problem can be challenging, particularly if it is intermittent, or like yours, only when the radio was turned on. You have to pity the mechanic sometimes, but it does highlight the need to be observant when you find a problem. Write down as much information as you can about what happens, when it happens and anything else that might help the mechanic diagnose it.
