Asked by Aug 06, 2013 at 05:40 PM about the 2007 Hyundai Sonata

Question type: Maintenance & Repair

My 2007 sometimes will not start after I have driven it while.  Usually when the outside temp is >100deg.  The battery is good and all lights are on.  But nothing happens.  Does not even try.  After about 30 mins it will start OK

I'd take a look at an undervoltage condition at the starter solenoid when the start position is engaged...the problem could be with the starter switch~

of course the battery if older than five will deteriorate as it refuses to take a charge 10% per year...so get a NEW battery~...also the connection of the black wire to it's spot on the chassis first wirebrush the chassis then the lug and bolt them back together so your 300 amp cold cranking potential will be there~

I have a 2009 that is doing the exact same thing. It seems to happen when the temperature is above 95 degrees. It will not start for 15 minutes to 3 hours. The starter never even tries, just silence. The accessories work fine and we replaced the battery. Only happens once or twice a month, but extremely annoying. The positive terminal on the battery is warmer than usual.
