#13 of 103 WARNING!!! deadly Drive-by-wire on 2007 Rav4 V6 Sport
May 22, 2008 (7:16 pm)
Went to pass a 40mph slow van today. Was in Drive on the AT which kicked down to 3rd. When the pass was completed I pulled back into the lane and let off on the accelerator BUT!!!! The car kept accelerating in 3rd, climbed above redline at 7k and kept accelerating very fast.
Shifted up to 4th and it kept accelerating. Same deal in 5th. Cruise was off. Fully free motion in accelerator pedal. Pulled it back to neutral and revs pegged at somewhere way North of 8K. By now we're going WARP 10 with lots of ugly blue smoke pouring out the back.
Killed ignition just before hitting the car in front of us. Drove off the road at hyperspeed, hit the puckerbrush, and luckily got it restrained and stopped without bashing anything.
Probably slaughtered the brakes and engine both. Haven't seen that much smoke in back ever on a civilian road. Sure smelled bad in the engine bay.
After calming down the dog(tied down in the wayback), tried to start engine and it ***immediately** raced towards the redline.
Shut it down and got towed to the dealer. Disconnected the battery, reconnected and tried to start again. Engine races to redline. Shut it off.
This happens in neutral and park. Obviously nobody dares engage the AT. The drive-by-wire is supposed to have a rev limiter at around 3500 when the AT is in neutral. That's either hoaky or the dealer's wrong about it. And, at least on this car, there is no rev limiter north of 7K (or it also failed).
Checked for any obstructions around the accelerator. None. NADA!, nothing hanging up the pedal.
Went to engine and banged my fist on it in frustration. Dealer later started it and it idled the way it should.
With only 13k miles on this 2007, it's still under warranty. Am waiting to see what the dealer discovers. But I doubt if I'll ever trust this car again and certainly won't let my wife drive at ever again. It's a killer!!!
We're going to insist that all the electronic controls are replaced at the minimum. Will also do all the sleuthing for engine damage. If Toyota gives any trouble about all of this, we'll be in court with witnesses. This car is a killer!
This car is very cherry, has never, until today, been off road. Has been maintained by the book, and has never given any trouble until this.
Since the 07 Sport is drive-by-wire, there probably isn't anything like a gungy linkage, stone stuck in a spring, or any of those hijinks. It's acting like something severely wrong in the electrics. Whatever it is, it is very dangerous and life threatening. We were very fortunate today that we didn't buy it, or hurt anyone else. If this has happened in the city we were headed for, there probably would have been some nasty unpleasantness.
We have filed a safety alert/complaint with Toyota and the NHTSA. Toyota was blase about it, but the feds are very concerned and say they'll be on Toyota's case immediately. We'll see. Have also talked to ConsumerReports.
We're supposed to hear from some mucky-muck at Toyota. We'll see.
In any case we are sending out a warning to all our friends who drive similar Toyotas. We don't want anyone to buy it because of Toyota's flawed drive-by-wire.
Sincerely hope this doesn't happen to anyone else. It's an adrenaline rush we don't need and you don't want.
#15 of 103 2007 V6 Loud Hum
Jul 11, 2008 (7:38 am)
Okay, I have this loud hum that sporadically appears from somewhere in the vehicle and seems to be amplified within the cabin. I am not completely sure, but I think the hum is either coming from the power steering unit or the fuel pump. Has anyone else run into this same thing?
#16 of 103 (Expensive) Hissing Noise?
Aug 11, 2008 (5:37 pm)
I would really appreciate some help if someone could lend it. I own a 2001 RAV4 with 91,000 miles on it. Recently it started making a noise that three mechanics cannot seem to agree on. Here is the description:
The car is making a relatively loud high-pitched hissing noise that sounds like it could be either (a) air sucked through a system incorrectly or (b) a piece of metal lightly scraping against another piece of metal.
The car makes the sound only when it is (a) idling (AC on or off) and (b) when the gas pedal is being pushed after it has been not touched (i.e., when accelerating) or when it is coming back to that position (e.g., when I let it go because I am going downhill). In other words, the noise is not there - and definitely not simply overpowered by engine noise - when the gas pedal is pushed down (except for the first few millimeters).
The Analyses (so far):
One mechanic thought it was the tensioner or associated belt but replacing both the tensioner pulley and the belt did not fix it. Then he did not know. Another mechanic thought it might be the injection system but was not sure either and suggested living with it for now. One Toyota mechanic thought it was the tensioner at first but then thought it might be air. He later concluded that it was the throttle body that needed to be replaced for 1500 dollars.
However, the second mechanic could not believe that they could be sure about this - he thinks it might simply be their best guess and merely a "broad attack fix" so to speak. All mechanics seemed to agree, though, that there is nothing dangerous happening and that the car would not be damaged if I ignored the noise. As a scientist, it drives me nuts not to know what it is, though, and of course I am afraid that I will have to spend 1500 dollars one day as we simply cannot afford that with our young son right now.
I am not sure whether this makes sense but if anyone could help I would appreciate it!
Thank you very much!

Not sure if I have the same problem, but it is the same location. I have a 2003 Sequoia which has been having a RANDOM piercing or screeching noise coming from the floor near the brake pedal. Sometimes it is hard to tell where it is coming from but the Toyota svc. mgr. who witnessed it, thought this was the location the sound was coming from. After leaving it at Toyota dealer for 4 days, they said they could find nothing wrong and was never able to get sound to be heard while they test drove it! Each time I leave and drive away, it starts up to beat the band! At times it seems like it begins or ends when pressing on the brake pedal. At other times, it seems to come from the gas pedal.....hard to tell. I also have had it continue for a few seconds after the engine was shut off! Car seems to run just fine but noise is very annoying and must be stopped. Any help would be greatly appreciated!!
#18 of 103 Toyota RAV4 1999 3 door model - cambelt change

Hello I've just had the cambelt changed. When idling the revs start at 1500 and go down to 900 after 5 minutes. Car seems noisier than it was before. Can you let me know if this is a normal rev reading please?

We have a 2008 Rav4 Limited with V6 and AWD. We have been experiencing a loud humming noise for months. It seems to be coming from the rear of the vehicle. The vehicle is now at the dealer for the 3rd time for the same problem. They are not able to replicate the problem and yet we hear it whenever we get it back. The vehicle was purchased brand new and it's just a year old. We have contacted a lemon law attorney-you may want to check with your state's attorney general's office.

If it were I, I would try having the dealer's mechanic ride in the vehicle with me and point out the sound to him before I would divert a lawyer from chasing ambulances.

I did have a mechanic ride with me, but the noise occurs randomly and was not heard during the drive. The dealer has had my car on 3 separate occasions each time for a number of days and they never heard the noise. However, no more that 24 hours after we got the car back, the humming noise was present. After doing more research it seems that this "humming" noise at low speeds has been a known problem with Rav 4's and Toyota has not fixed the problem. Trust me, I am not an individual who seeks to pursue law suits, but I feel in this case I need to protect myself and my family. I work extremely hard in the difficult economy and when a product does not live up to the standards/expectations and the company does not rectify the problem than action needs to be taken.
