Hi guys,

I have a 2008 GMLS with just over 41K miles. This car has been perfect up to about a month ago. When it gets hot outside and the temp gauge is normal, it sometimes will just sputter and die. Had to have it towed to dealer and they couldn't find anything wrong. No codes, nada!

The car has run fine until yesterday afternoon, got in and wouldn't start. It sputtered a few times, no go. Tried to reset the computer, no go. I left it in the parking lot at work and came in this morning in my F150. The car started right up like nothing has happened.

This seems to happen only when the temp here in the South is hot as hell. This is the second time for this. It's apparently an intermittent prob or a sensor temporarily malfunctioning.

Anyone heard of this prob and the fix. Can't continue with this much longer.

 

The car finally acted up at the dealer. Turns out it was a weak/bad fuel pump which is covered under the power train warranty. Glad to get this thing fixed!.
