i have a 2008 ISF and recently been having some very strange issues. I initially noticed my truck button inside the can was not working. Then while turning right my power steering seemed to momentarily go out while a plethora of dashboard lights came on. The brakes also seemed to catch or something during this turn. It has happened a few time when I turn right. Electronics flicker and the stability and power steering feels momentarily glitchy. Then today I go to start my car and it is stone dead. I plug it into to my portable jumper and it immediately starts back up and states my battery is at a normal level. On a side not me I noticed my rear window switches aren't working. The battery is less than 6 months old.

 

Typically this kind of stuff almost always means a faulty battery. Get it tested.

 

Sounds like one or both of the battery terminals are not properly secured.

 

I'd start with a new battery too

 

check and clean battery terminals and cables. have battery and alternator tested. go from there.

 

This is my same thought. Turning the vehicle causes it to flex, and if you put enough tension on a wire that is not properly secured, the connection may be intermittently broken. Double check that everything is clean and properly secured.

 

Just had this stuff happen to a client of mine on the same year ISF. Cleaned battery terminals, which solved the problem for a few months, then he called me and said he eventually just gave up and bought a new battery and it's been working ever since. Almost a year now with no issues.

 

After the ELF campaign.. the dealer didn't secure my negative terminal... All my gauges went out while driving
