Question type: Maintenance & Repair

Bought my car 4 months ago have had my car in for service
multiple times for malfunction code light ,every time they
say nothing wrong , it was last in for service in May again
they said nothing wrong , since last time in service code
light has not come on at all , the other day my battery and
my alternator went car totally dead should the malfunction
code light have come up ? I put a new battery in , with
hopes that that was my only problem malfunction code
light still did not come up  I realized there were four relays
missing under the hood the place that my car is at 4 service
told me that the alternator is dead also , shouldnt i have
gotten some sort of warning before the car became
completely dead

...could it be that with the dead battery, someone tried a jumpstart...only they reverse jumped only to cause failures of the alternator...etc...why the relays are missing is a mystery...Driving through Nevada and need service from a road- rat...can happen and you never really know if what they are doing to your car is legitimate~ recommend get a cheap rebuild, or good rebuilt alternator, assure the battery connections are without corrosion...and with the renewed electricals should be okay then~ 2006 is a long time to go without major mechanical work needed~

Thank you possibly helpful, my main question was should the malfunction code light have come on

1 out of 1 people think this is helpful.

There is a dedicated warning light on your dash for battery/ alternator issues, not a code. That lit should have come on to warn you about alternator failing.


of course this is an OBD-II vehicle...connect the obd-II reader and "clear codes"~ will inform you what the deal is~ bout 15 bucks from newegg~

Malfunction code light has been coming on ever since I bought the vehicle 4 months ago I have replaced the alternator and the battery just this past month now once again the malfunction code light keeps coming up flashing and then shutting off when it does it runs like crap

Everytime I bring it there they say nothing wrong with the car no code lights coming up they have cleared it a couple times


possibly, you filled it past the first click...this plays hell with the charcoal and evaporative it will go away eventually with use~ if not suspect one of the oxygen sensors...but would report on the OBD-II...a defective evaporative system would too... might make sure the gas cap is sealing properly~
