SUSPENSION, STEERING, SERVICE BRAKES
When driving the speed limit, going downhill, uphill, straight, around a curve, in the rain or dry weather, the vsc and slip/trac lights up, the abs system is activated / brakes engage. I loose complete control of the van. I can no longer steer or break. The breaks engage, but it causes the car to veer to the right. I have taken the car to the mechanic 5 times now and no codes show, even after he is able to the vehicle to repeat this behavior. It seems to happen a lot on off/on ramps. It happens mostly on highways, but it has happened on two lane roads. The vehicle is completely dangerous to drive. It has almost caused several accidents. I have replaced the Yaw sensors and had several alignments and this still happens. After a lot of research, we have found that this is actually really common in Toyota Sienna. People are saying that the bushings in the rack in pinion wear out and the entire rack and pinion system needs to be replaced. Some people have replaced the rack and pinion and claim that there is still a problem. But the majority say after the rack and pinion is replaced there is not further problems.

TIRES, TIRES:SIDEWALL
P225/60R17 98T: Tires create vibrations in the steering column. One tire in particular creates severe vibrations that mechanic states could lead to problems with the steering components. Mechanic http://www.japaneseautorepair.org/ e-mail [email protected] (John). Coordinated w/ Sandy Boulevard Line up shop and one tire could not be aligned due to defect. 2004 Sienna van (140,900 odometer miles) is equipped with Toyo Observe GSi-5 195/65R15 91T (separate 16" rims purchased from Les Schwab) and there is no vibration at all. Les Schwab last tried to "balance" the defective tire in 2019. I have about the 4rth appointment Aug 21 2021 @ 9AM. I will also take the 2004 Sienna van to Japanese Auto repair (web site and e-mail above). to look for any defects. I probably need to put the Winter Observe GSi-5 tires on the car for safety, but they wear out quickly on summer hot roads.

The rubber part of the VVT-I oil line appears to worn and leaking. There is a Toyota Campaign to replace this faulty designed oil line with a full metal line, but for some reason my 2007 Toyota Sienna VIN is not showing up with this campaign. The oil will leak from the engine and cause failure. Please re-check which vehicles are impacted by this Toyota design problem in this VVT-I oil line.

While driving my 2007, Toyota Sienna on a sunny afternoon, the spare tire dropped from under the vehicle. Specifically, while I was driving in the parking lot of the local international airport, I drove over a speed bump (about 5 mph) and heard a loud THUMP. When I looked in the rear view mirror, I noticed my spare tire on the road. Upon retrieval of the tire I noticed some rusty metal parts, adjacent the tire, that appeared to have been broken loose from under the car. Thankfully I was not on the highway when this happened and that no one was behind me. Someone could have been killed or seriously injured. While completing this document I learned that my vehicle was recalled for the aforementioned.

rear differential has very scary noise while driving, mechanic identified that we have to replace the rear differential which might cost $2500 to $3000 the same problem do exist on RAV4 and it's under recalls, while many people have the same problem for the same year like mine 2011 Toyota sienna AWD and other years to 2018 . This issue is the manufacture responsibility not the owner of the car as wear and tear items " my van has about 126,000 miles on it. Please a recall should be issued it is across for many people

The Trac Control activated numerous times while diving forward on the highway and turning on country roads. It beeps about three times, activates the brakes on the left side of the car pulling you and then stops. The skid light activates on the dash while this is going on. Numerous same incidents are listed online. The brakes activate to one side while you are driving for not reason. I see a lot of people online that have the same issue. I am surprised this is not addressed and when you call the dealership they say it does not do that. That is not what the trac does. It does not activate braking.

I was pulling in my driveway when this incident happened. When exiting my vehicle and opening the driver side door this is what occurred. The driver side sliding door cable snapped and could have potentially hit the driver or me and which could have injured a body part especially the eye or hand. It also made a loud popping noise. There was no warning lights that this would happen and now the door will not open which causes a safety hazard because in case of an emergency this door may need to be opened to escape for safety reasons. Thank you for the investigation of this matter.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, VEHICLE SPEED CONTROL, WHEELS
I had the control arms replaced, then one of the bolts came out after a few thousand miles. I had that bolt replaced and the problem started happening intermittently after that. Everything will be functioning fine and then the speed of my vehicle is inhibited and it is hard to accelerate. It is very difficult to get from 40 MPH up to 50 MPH. On slight curves, not always, it will beep and the slip indicator light comes on and will apply the brakes on what feels like one side. This has happened at 35-60 MPH. The slip indicator will beep sometimes until I decrease my speed to under 25 MPH. I took it into a reputable tire and front end shop and they replaced a wheel bearing with sensor, and 2 front tires. The problem happened again within 5 miles and the shop said I need to take it to Toyota dealer to have it the steering angle sensors recalibrated. The Toyota dealership said that this is something that the vehicle does itself. They inspected it and took it for a test drive and said nothing is wrong. The problem happened again within a few miles of leaving the dealership. I have read countless forums of people experiencing the same thing in their Toyota Sienna and having the dealership telling them there is not a problem. I have also found that the solution could very well be worn rack and pinion bushings that are creating the play that are triggering the sensors. I don't think they gave it a proper inspection. This is a very dangerous problem, and even more so when the dealership is saying there isn't a problem. I am feeling very lost on what to do with my van right now. I have spent $1100 and 3 days of my time with the same thing happening. I

Vehicle began 'whirring' metal noise from underneath. Local mechanic said it was coming from rear differential. I took it to a Toyota dealer, they said rear differential coupler needs replacing ($2159) and drive shaft ($992). It seems the bearing ring inside this sealed unit has failed. Noise is continuous while driving, concern of part failure - we are taking vehicle on family vacation. Researching on - line it appears to be common problem with the Sienna's. Toyota had same issue with RAV 4's and issued recall but have not for the Sienna's. I called Toyota corporate in TX (got up 3 levels) to no avail, and it curt tone, they said they cannot help. Based on other similar stories on line from other Sienna owners, this seems to be a common very expensive design flaw problem with this vehicle.

Grinding noise began from the rear of the vehicle increasing as acceleration increased. Took to the shop and found at the Rear Differential failed at 75,000 requiring replacement for thousands of dollars. The same year RAV4 has been recalled for this already - the Sienna should have a recall also. The dealership had the part on the shelf, surprise surprise.

The rear passenger side sliding door cable and motor assembly on the Toyota Sienna failed, causing the door to become completely inoperative (cannot open nor close) and the broken cable nearly cut my wife as it broke under tension and came flying out toward her as she was trying to close the door normally. The cable and motor had been replaced in 2015. The cable and motor on the rear driver side sliding door was also replaced in 2013 and 2017. The problem was confirmed by Woburn Toyota (dealer) and reported to the manufacturer. The manufacturer has confirmed the failure and safety defect, but refuses to provide repairs. No warnings were provided, no recall was issued, and customers were not notified of internal safety bulletin POL12-02 issued by Toyota.

Car has about 16,000 miles. When accelerating slowly from a stop, vehicle hesitates, shakes, and runs rough as it slowly progresses thru first, second, & third gears. After transmission gets in fourth gear, hesitation and roughness goes away. This issue is rapidly getting worse.

WHEELS
on July 3rd, traveling on highway to airport tire blew out (right rear). Pulled to side of road and attempted assistance but this was friday afternoon before july 4th holiday, NOTHING was going to happen except a tow - possible wait as long as 2-3 hours. reportedly the Sienna has drive flat (50 miles at 50 mph) We drove 5 mph for approx 3 to 4 miles to tire store/Les Schwab. Flat was replaced but then on inspection ALL remaining tires had card showing wear on inner tires. ALL 4 (including the blowout). Pictures submitted . Of particular concern is that we had taken the vehicle about 10 K prior (March)specifically for tire wobble noise and to fix alignment. Wear was noted, but no safety concerns raised and no cautionary recommendations offered. When we brought the vehicle and tires to the dealer AFTER the blowout we were told by service manager that the early wear was a known problem to occur specifically on the all wheel Siennas. Again, NO CAUTIONARY ADVICE GIVEN in March despite recognized wear and this known history. We had a blowout in heavy holiday traffic at 60 mph less than 10K /3month later. This easily could have been catastrophic. We reported to Toyota to a "Beth" at customer documentation and risk reduction department who did an excellent job of deflecting causation/potential blame and advised us to contact the tire manufacturer or the dealer. Absolutely no evidence of concern for safety - ours or those around us - at highway speeds. Review of web shows known problem, service manager volunteered it to be a known problem of premature wear, with service given shortly before incident WITHOUT GUIDANCE. "Beth" told us she would document our concerns but that there was nothing Toyota could do or would do other than documenting. I am hopeful you can investigate further and initiate some reparative process before there is a preventable catastrophe much like the Prius accelerator problem. we will send copies of to wherever is useful

VEHICLE SPEED CONTROL
I have a 2000 Sienna with 305000 miles. I have never had trouble with this vehicle until about 2 weeks ago. When I am stopped and my car is in drive, I just tap the gas pedal for a second and the engine RPM will increase to about 2000 RPM and will stay there until I put the car in neutral or turn the engine off. This is a problem because my breaks barely hold this and I must put the car into neutral for the car to stop pulling forward. Putting the car into neutral resets the rpm. If there is no car in front of me, I can release the brakes and the vehicle will continue to accelerate until the transmission switches to second gear, at this point I can drive normally. One time the vehicle continued to accelerate even after switching gears, I put the vehicle into neutral and the engine went to over 4000 RPM, the brakes could not stop the vehicle, I had to turn the engine off. The gas pedal is not sticky or stuck, floor mats are not in the vehicle. I can rev the engine normally when I am in park, this only happens when I am in gear. I have checked the Throttle Body, Throttle Position Sensor and disabled the cruise control module, I can see no reason for this to happen. I have seen many complaints about this same issue online but have not found a resolution. I can buy an ECM but this is an expensive trial. I will take it to the dealer from here.
