View 7 RepliesI have a 2001 Toyota Sienna with 115,000 miles on it. After about 15 minutes of driving, a vibrating buzzing dentist-drill like sound begins to come from the back left of the car (this is also where I put in the gas if that has anything to do with it). I do not know what it sounds like from the outside but its definitely a buzzing sound from the inside. As I increase in RPMs the buzzing sound gets more and more high pitched.
I do not drive this car very much, but about a month ago I was driving down a mountain using the breaks a lot and the buzzing sound started for the first time with a rubber smell. At this point because of the rubber smell, we just thought it was an issue with the breaks and after taking a 20 minute rest, the car drove the rest of the 400 miles or so perfectly fine without any buzzing. I don't use the car very much because I am in college, but when I do, like I said, after 15 minutes this buzzing starts.
I have a FWD 2009 Sienna with 62k that vibrate on cold days. It only vibrate when the shifter is on drive or reverse while stepping on the brake. There is no vibration while driving, only when I'm at a stop light. After the engine warms up, the vibration goes away. I can feel the vibration on the steering wheel. I just want some kind of knowledge before taking it in.
View 3 RepliesThe rear vents in my '09 Toyota Sienna minivan do not blow heat, only cold. The vents up front work just fine, but when I turn on the rear heater (whether from the front controls or from the rear controls), my kids get iced. They never blow heat, even after long periods of time. (Also, the upper vents in the back do not blow strong, even on High, although the lower one does). I heard something about an interior heat sensor, and about blend doors.
View 1 RepliesI have a 2006 Toyota Sienna Van that has 111,000 miles on it. I have a problem with both the heat and a/c. If you have the heat on but are just idling, it begins to blow cool air. Likewise, if you run the a/c but are just idling the air begins to blow warm. In either case, if you rev the engine (either in park or nuetral say at a red light), the air gets warmer if the heat is on, or colder if the a/c is on. In other words, the temperature only works correctly if the rpm's are up. Could this be a stopped up heater core.
View 1 RepliesI have a 2004 Sienna LE and it has left/right signal problem (not working) in the morning or when the weather is cold. The problem usually last for about 5 to 10 minutes until the inside car temperature becomes warm.
When this problem happens the emergency lights are working. Only the signal left and right do not work.
Is this a common Sienna problems? I brought the car to the dealer but they refused to fix it because they cannot duplicate the problem. I am guessing when the warranty has expired, they will make suggestion to replace the part but not until then.
When I turn on the heat, I only get hot air through the drivers side vent,the passenger side vent is very cold. I had it in to be worked on (at a Non-Toyota shop)and they tore it completely apart and could not diagnose the problem. It affects the entire system,meaning the air going to defrost is also hot on the drivers side and cold on the passenger side.
View 7 RepliesI have a 2001 Toyota Sienna xle that started running rough when the weather turned cold. When started, the car idles very high and will not shift properly until it was been running for around 5 minutes. After that it will run well for about 10-15 minutes and then begin to run rough or poorly. The problem is very noticeable at low speeds and when stopped. It never actually kills, but it feels like it is going to. At high speeds it is less noticeable but occasionally you will feel it jerk or chug like the transmission is slipping or a belt or something.
I took it to a mechanic who checked the codes and found that the ignition coils were supposedly bad. I say supposedly because they replace three of the ignition coils and the problem still persists. I then took it back to the mechanic who then told me it was the oxygen sensor. The o2 sensor was replaced and the problem is still there with no noticeable improvement. I again to it back to the mechanic who tells me that they scratching their heads.
I have done some looking around on the internet and have found some discussions that seem to have some promising leeds and actually last weeks car talk show had a caller who described a similar problem. The guys told him it could be a oxygen sensor but they thought a better possibility would be EGR valve or a vacuum leak. Not sure if this sienna has an EGR, but I plan to suggest looking into it to the mechanic. Also, I found some discussions talking about the idle control valve and the engine control module.
I have a 2002 Toyota Sienna van. My garage failed to check the brake shoes as requested, so I gouged the back brake drums and had to have them replaced. Shortly afterwards, whenever I brake, in the last 2-3 seconds before I stop there is a thumping noise from the right rear wheel. It will thump a few times, maybe 2-5 times, perhaps one thump per wheel rotation. I don't feel any pulsing in the brake pedal, and except for the noise braking seems normal. Could this be due to the shoe adjustment being too loose, so the shoe has room to pulse inside the drum?
View 2 RepliesI am noticing an audible vibration coming from the rear of my wife's 2004 Sienna van when applying the brakes. I have inspected and confirmed there are no fluid leaks,there is ample material left on all pads and the pads still fit snugly into the retention clips. Also, the pads and rotors show no sign of uneven wear. Front brakes were replaced in 2009.The van currently has ~63000 miles on it.
View 2 RepliesI have had that car, the best one I have ever owned, since shortly after Nine-One-One, a date some of you may remember.
I never open any door but the driver's door with the key. Several months ago, for some reason it occurred to me to try and see if they worked.
Nope, both the rear hatch and passenger's door lock would not open with the key. I assumed that the mechanism corroded up over lack of use over the years.
I thought, Well, crud. But, since I haven't used those door locks in over 12 years, I can probably get by.
I thought I had lost the spare car key when I was in Texas in December. To my surprise, I saw it on the key rack in the kitchen here in rural Mexico. I took it out to the car to check it out, and it opens all the doors.
I compared the keys, and one of the 'vanes' on the key I use all the time is a very tiny bit smaller than on the spare key. My guess is either that key never opened those two doors and I never noticed it. Or, it has worn over 12 years.
So, I guess when I get back to the States, I will have a copy made of the spare key. I am also going to post this on Sienna Chat for obvious reasons.
Thumping noise in rear passenger side. I removed pads and rotors, inspected and found nothing wrong. I decided to replace the new rotor with same and the thumping is still there, but only with the brakes being used. Nothing felt in the brake pedel and the the van stops fine. So why the thumping noise?

View 3 RepliesIn my 2003 Toyota Sienna, the ABS system comes on at low speeds. Since I will be trading in shortly, don't want to pay for costly sensor repair. Looked at fuse box to remove ABS fuse, and found 3 fuses that are labeled as ABS. Which should I remove?
View 4 RepliesMy Sienna's Got the Shakes! At around 30mph and higher, my 2004 Toyota Sienna starts with a constant vibration coming from the front end. It gets faster as the speed increases and it only happens when I'm accelerating... when I take my foot off the gas it goes away. I unknowingly bought the car with this problem, and I'm trying to decide if it's worth it to fix it or sell as is, but I'm getting stumped about the cause. A couple mechanics thought it is from bad motor mounts. I replaced the front mount because it was the easiest to access and could clearly be seen as cracked in the rubber. However, it didn't seem to change the vibration at all, and my mechanic then wasn't convinced that spending money on trying to replace the other mounts was going to do the trick. Another person took a look at it and didn't think it was the motor mounts either, but thought it was something in the drive train which would need to be checked out by the dealer which would be fairly costly. I would love to get it fixed because the rest of the minivan is in good condition.
View 4 RepliesI looked up the service history of a Sienna 2006 (have been planing to buy the minivan) and found that it had a few incidents with AIR BAG ON. When I initially searched for 2006 Sienna I mostly hit the door latch problems. Looks like the airbag issue has been reported on several blogs and there is no recall yet on this issue.
My question is, if I buy extended warranty, whether this would cover the repair cost or not. Or, should I stay away from 2006 Siennas? If so, which models/years should I avoid?
My Toyota Sienna 2002 van has been stalling when I stop off and on for about 2 weeks. Most times it starts up again and continues to run. I can go days and it doesn't happen then yesterday it happened 7 times in the course of 10 minutes. I've had it connected to a computer diagnostic system three times, couldn't find any error messages.
View 2 RepliesMy 2010 Toyota Sienna alarm keeps going off randomly...there is no method to the madness. It happens after it's been running or not. It happens at all hours of the day and night. It can happen four times in a row and then not for days on end. It's literally driving me insane. I can stop it by pressing the unlock button on the remote. But it will often -- though not always -- do it a few more times after that. So, I open all the doors/trunk remotely and that usually puts an end to it for that period...but not always. But it always happens again...whether it's the next day or seven days later. The mechanic says they need to keep the car and hear/see it happen...but that means leaving my car with them for days on end, which I simply can't afford to do.
View 2 RepliesMy wife's 2005 Sienna is a very reliable vehicle. But occasionally when I drive it a fair distance--50 miles or so, but not always that far--the check engine light will come on. (It's something vague about emissions, but isn't it always?) And then a day or so after my wife drives it again, the light goes off. The van seems to run fine at all times. So is it something I'm doing when I drive it?
