My wife drives our 2002 RAV4 2WD Limited with 45K miles. I hear a very intermittent whistle coming from the dashboard. It can happen when starting the car but mostly happens when stopped or right after the car is turned off. It sounds just like a human whistle, one note, varied length, increasing in pitch. As if a gas is venting through a reed from the A/C. I live on Maui and almost always have the A/C on. I took it to the Toyota Dealer here and they were unable to fix it and never heard it. It's very intermittent and might only happen once a day or less. Although my wife is enjoying the positive attention (the whistling) she's had enough.  HELP please.

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. |

| 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? | |

Hello everyone, 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 Noise: 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 Conditions: 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!

| 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? | |
