Did I get Hustled?

Look at it this way, with our GN's. A low battery condition causes the fan delay relay to turn the coolant fan on high, which swiftly kills the battery. That's the most common condition you'll see with the GN's in storage.

The fan delay has a "keep alive" circuit and will malfunction if it's not up to the system voltage. I've been preaching for years to take the delay relay out of the equation for this reason (and the fact that they corrode internally, adding to the fault condition).

Beat me to the punch, this is exactly what I was gonna say.

Lots of 2006 and later cars have a "CAN" (computer area network) system which controls just about everything on the vehicle, from lights to wipers to engine and transmission control. Low batt voltage or blown fuses can make some seemingly strange things happen with the CAN. At least they seem really strange until you find out how the CAN control system is engineered and how different functions are prioritized and defaulted.

The good old days of hardwired switches are long gone....

I have a 2009 Nissan Maxima. Last night when I stopped the car the break lights and fog lights wouldnt turn off. This morning the battery was dead. Wifey took the car to the dealership and they charged her for a new battery. I asked the dealership, "It seems like a car electrical issue and not the battery". There response was, "When batteries are near dead they can make the car do weird things like what happened last night". My question is, IS THAT TRUE OR DID HE HUSTLE US?

On the battery thing, one dead cell can reap havoc. Can it make the lights stay on? That would be hard to swallow but if it is a post "CAN" vehicle it may be a factor.

Let us know any further outcome.

I found this out on my 2008 Ford truck when I went to do my snowplow lights. Any added load to had to be isolated from the factory system. A real pita when in the past it was routine to tap onto a light circuit and be done.

A battery can short out internally.
I had adodge van years ago 78 i think ,I was walking up to it and could here music playing and it was my van The key was in my pocket the radio was off and still playing.i changed the battery and no more problems.
Christine???

A jag is known to be the biggest POS electrical nightmares ever made... I refuse to buy or trade for one to this day. Blew several nice sales because I refused to trade...

yeahh i wouldn't touch another one.

this is what happened in my situation.

The fact that you started it and drove it to get the Battery replaced would make me wonder if it was bad . I would vote for a bad connection if so they surely cleaned it and you will never know the difference .

The Lucas system that is in British cars is more aptly named "Lucas the Prince of Darkness".

That is all.

I have come to the conclusuion that when you walk into any automotive repair shop that you have never dealt with you are in for a scewing.

I stick with the same shop & go in armed ahead of time knowing what the item or labor will cost. I have them trained to ask if I want to repair it myself. They also give me frequent repair discounts and cash discounts.

Yes this is possable. I work at a nissan dealership and have seen this happen. All the lights along with other electrical systems are controlled by the ipdm which is basically a computer contolled relay box. When it has about 10 volts or less it is no longer able to turn the relays off and the lights will stay on untill battery is completely dead. As far as warranty the battery is covered 100% for 1yr 12k, 50% 2yr 24k, and 25% 3yr 36k for the part and labor is covered 100% for 3yr 36k

thats why you get a B4B buick... if the battery goes dead, nothing happens... and i mean nothing
