2008 Toyota Avalon Battery Problem

Purchased car in October 2007. In April 2008 when I tried to start the car the battery was dead. Dealer replaced battery. September 2008 the battery was dead when I tried to start car. Dealer is once again picking up car right now. What on earth could be the problem? Could it have anything to do with electrical system or smart key? Help

I doubt this is a smart key problem, the key uses a chip and its own battery. Something in the car is causing a drain, a light is staying on possibly. Trunk light, glove box light, under hood light... maybe you have a portable GPS unit plugging into the auxilary port? Just a thought. This is not a common problem that has been reported by Avalon owners as of yet.

Toyota avalon 2000 battery flat ...put starter pack on battery start pack fully charged .....did not start car only clicked starter motor gone ?


Those starter packs are really for a boost . If your battery is dead
its better to replace it especially Toyota they seem to be finicky about a good stiff battery
if you have a multi meter put it on the battery terminals and have someone try to crank while observing the voltage
if the voltage drops below 10 volts usually that battery is on the road to letting you down

My key fob is lost and I need to get into a avalon


You'll need the door key with a dead battery because the key fob won't unlock the doors with a dead battery lost or not.. Toyota dealer is the only place a new key fob can be purchased that will work.

Avalon won't start, fast clicking noises


Sounds like a dead battery issue. If someone can jump start you with battery cables connect red to red post on battery and black to your car frame or other ground. If the car starts easily it indicates a discharged battery. Then you need to determine why the battery is discharged. If you can drive to a local autoparts store they can use a machine to do a battery and charging system diagnosis at the curbside. Autozone, Advance, or Oreilly all do this. If the battery is the original from the car when purchased it is probably time to replace it. If its a new one (2 years or less) the culprit may be the alternator. The clicking noise is a dead give away that its a battery or alternator issue. The clicking by the way is the starter trying to engage and turn motor over to crank it. Its not getting enough power to turn the engine over (a tough task) and is clicking.

2008 toyota avalon dead batery


There sounds to be a problem with your alternator. If the car went dead every few hours or week I'd say its the battery. But if the car lasts 3 months between problems, then you're battery is a champ despite fighting a losing battle.  Do you ever take long trips that coincide with this problem? If your battery isn't recharging then it could drain to dead on a longer trip.  There could also be an electrical problem like a bad ground that only shorts bad every once in a while. Read the voltage when the battery is connected to the car with everything off and then again when the battery is disconnected from the car. Also, have you had the alternator checked? Have you inspected the engine for bad grounds? Have you tried buying one of those battery saver devices? Hope this helps.
