RAV4 Battery problems - solved at last? by mr2girl
May 10, 2007 (3:00 am)

My RAV4 was bought in September 2001. I have had 3 batteries, 2 were replacements for "faulty" ones. I have had to call out the RAC (here in the UK) several times to start the car, thereby losing my no-call out discount and have twice had a flat battery at the airport car park after leaving the car for 12 days or so. If the car is left for more than 4 days it will not start. Okay, I have only clocked up 14,000 miles in 5 years but I had an MR2 classic sitting outside for days on end for 10 years with no problems. The car is waiting to be collected from a Toyota garage this afternoon after being on a trickle charge all night as it was only holding a 20 per cent charge. The new manager has told me that the ALARM drains the battery (present battery is 16 months old and was last checked about 3 months ago for the same problem). Now I am only going to alarm the car when it is parked in a public place. At other times I am just going to use the key to lock the doors - all 3 of them - what a drag! Will see if this works. Perhaps others could try this if they still experience problems.

Toyota/Lexus NOT Battery problems - NOT solved at last? [mr2girl] by rkljajic

I wish we could find some attorney who wanted to look in to this. My friend just purchased a fan-cy LEXUX sedan and it won't start after three (3) days. They told her any longer than 3 days needed to be plugged in to an electric outlet. She's attempting to get the Dealer to take the car back, full money refunded.
 
Something is wrong with Toyota/LEXUS electric system. When it's all going to come out is the question.
 
We all own many cars at many homes in many countries. This problem is only happening with Toyota/LEXUS. It is a problem and it can be life threatening (in my case). I'm not going to drop it until it's fixed for everyone.
 
If you know of others with this problem, PLEASE let me know!

97 Rav4 stuck horn by mmphilli548

Hello-
 
I have a 97 Rav4 and the horn became stuck while it was sitting in my driveway. I disconnected the battery for lack of a better idea. I would like to disconnect the fuse, but I don't know which one it is because I do not have an owner's manual. Does anyone know which fuse is the horn? Thank you.

After leaving my 2006 RAV4 on the driveway for five days, my RAV had a dead battery. I was able to jump start it and took it to the dealership to have this problem taken care of. After two days, it was determined that snow melted off the hood of the vehicle and moisture travelled through the firewall to an electrical harness and caused a short in the system. I was informed that a "bulletin" was sent out to dealer service departments concerning this problem.

I am replying to my own message due to the fact that I was given more facts on my problem. It seems that my problem was caused by a faulty "seal" in a windshield I had to have replaced(repair not made at dealership). I was told that the faulty "seal" caused moisture to seep down the firewall of my RAV4 and onto a wiring harness causing the "short". After learning this, I must say my dealership has been very cooperative with me concerning this problem and I just wanted to get this information out to others and to correct my original misinformation.

Fuse question by lloyd11

My wife has a 2005 Rav4. She went out to go to work to find that the front windshield wipers don't work.
 
Fine, blown fuse, no problem. I look in the manual, look up the information and look at the fuse block to find the slot (#35) empty. No fuse.
 
We have recently had a remote starter put in (Circuit City) and the wiring is a mess.
 
All of that aside, has the fuse block changed since the manual was written? I don't see how the fuse could just not be there.

2006 RAV4 Starting Problem by cincirav

I have a 2006 RAV4 experiencing intermittent starting problems. About once per week for the past 3 months the vehicle won't start. Turn the key, lights come on but then nothing. I sometimes hear 1 click, but wife says she hears nothing. We can try a few times and sometimes on the 3rd or 4th or maybe 10th attempt, it will start. My wife thought she noticed a correlation to the brake pedal pressue, ie. when it was soft the car wouldn't start, but if it felt hard, it would. I've since disproved that theory since a few times I'd press on the brake pedal first and pressure would build up, but the car wouldn't start either.
 
We brought it to the dealer who can't replicate the issue, so they won't do anything.
 
A previous car I had experienced a similar problem before I had the starter replaced, which eliminated the problem.
 
The car is still under warranty and the dealer won't do anything since they can't reproduce it.
 
Anyone know of this problem or have any suggestions?
 
I'm thinking it won't get solved til something actually fails and we're stuck somewhere.
 
Thanks.

Mine was the electric harness for the whole car.... by rkljajic

After three dealers wouldn't look at the car and said they also couldn't reproduce it a fourth, and wonderful and very professional dealer, Steve's Hometown Toyota, not only looked at it they quickly identified the very scary and life threatening mechanical problems. They were surprised it ever started/ran based on the very bad electric system. No problems since thanks to Steve's.
 
Needless to say, it was not a fun process, Toyota Corporate didn't/wouldn't help, it cost me thousands of dollars with an 18 month old Sequoia, it was covered under warranty of course and I'd rather walk across America than purchase another Toyota.
 
Good luck!

My guess (bet, really.) is that the starter circuit is not "completed", closed, due to the shifter "park/neutral" microswitch being out of alignment. Next time it happens step on the brake and move the shifter to the neutral position and try to start the engine. Or move the shifter out of park and then back into park.
