Can anyone point me in the right direction. Car shuts down at anytime. Battery is good, fuses are good. Mechanic says it's a wiring issue from the fuse box under the hood to the rear battery.

Have to take it to the dealer and trying to get an idea before I go in. Any help would be great.

Welcome to the site

We have seen fuse box issues where they separate and cause power failures. Did you have any trouble codes?

Here is a tsb for a problem to look for.

It's not for a 2010 but this could still happen to the later ones

#07-08-45-003A: Intermittent No Start/Long Crank, Start then Stall, Check Engine Light On, Airbag Light On, Reduced Power Steering Assist, Intermittently Functioning or Inop Electrical Systems, DTC P0442 or P0449 Set - (Jun 22, 2009)


Subject: Intermittent No Start/Long Crank, Start Then Stall, Check Engine Light On, Airbag Light On, Reduced Power Steering Assist, Intermittently Functioning or Inoperative Electrical Systems, DTC P0442 or P0449 Set (Inspect UBEC and Replace Connectors, As Necessary)


Models: 2006-2009 Chevrolet HHR

2006-2009 Pontiac Solstice

2007-2009 Saturn SKY

2007-2009 Opel GT

2007-2008 Daewoo G2X


Condition
Some customers may comment about one or more of the following conditions:

• Intermittent no start

• Intermittent extended crank

• Intermittent start then stall

• Intermittent check engine light illuminated

• Intermittent reduced power steering assist

• Intermittent airbag light illuminated

• Intermittently functioning or inoperative electrical systems

Upon investigation, the technician may find DTC P0442 or P0449 set as current or in history. These DTCs may also be accompanied by other DTCs.

Cause





These conditions may be caused by poor electrical contact between the underhood fuse block (UBEC) and its connectors. This poor contact may be due a bent or twisted male terminal (as shown above) on the UBEC side. During assembly when the UBEC is bolted to the connectors, the male terminal contacts the edge of the mating female terminal and pushes the terminal (1) out of the cavity. When this occurs, the terminal lock on the connector breaks and the terminal will no longer lock into the connector.

Correction
Remove the UBEC from the connectors. Visually inspect the suspect connector to see if the terminal has been pushed out of its cavity. If the terminal has been pushed out of its cavity, the terminal lock is damaged and connector replacement is required. Also, inspect the terminal for damage and replace if necessary. Straighten the UBEC male terminal (use a business card as a straight edge). If the terminal is twisted, attempt to straighten it using needle nose pliers.

Here is a picture that go's with the tsb showing the wire pin push out. I would check them all.

thanks for the info Lucky. just sifting through the threads about this issue. No codes came up but I'm hoping its a frayed wire to the solenoid.

Welcome to the site, you might also check the pins on the throttle body connector, but the usally sets a reduced performance code

on the front left side of the fuse box is a red cover that covers a bolt w a nut on it as in the picture
make sure that nut is tightened
if that is not nice and snug it will loose contact and die as you are driving. how do i know, happened to me and i figured it out while on the road to first school to go teach

also make sure ALL fuses in engine compartment including the huge ones too are pushed all the way down and nice and tight

Thanks for the posts and info. Chevy guy called today : Internally shorted fuse block.
New fuse block and labor $500. Seems reasonably.

I wonder what "internally shorted" means. Sound like the description I would give if the upper half separated from the lower half and needed to be reseated.

I am skeptical today.

Oldblue

if only there were pictures, then a 1000 words will have been saved!! I think internal shorted means loose wires and stuff.
