Issues with VSC. The sensor alarm goes off when driving at more than 50 mph and slightly turning the steering wheel. The car brakes itself and this is DANGEROUS. It happens all the time, it has been more than 5-6 years and we are to the point of not using the car on the freeway to prevent a potential fatal accident. I found posts describing the same issue with this model of Toyota. Car should be recalled to get this fixed.

Driving on dry pavement in mountainous terrain the slip indicator light/sound activates temporarily and the brakes can engage by themselves! Usually happens during right turns. I've been to several automotive specialists for mechanical & electronic diagnosis. I've replaced the lower control arm & the clock spring behind the steering wheel but the issue persists. Online searches indicate this is a common problem with Toyota siennas that is extremely difficult to diagnose & very costly to replace all the possible problematic components! I've had this problem since buying the car used several months ago.This should be a recall issue!!!!!!!!!!!

Check engine light, vsc light and trac off light on and off light intermittent. At any time the light goes on and off. It is nerve breaking knowing that the warning light and the problem can not be fixed by Toyota. I have my Toyota Sienna 2008 and it have a very low miles due to lights safety reasons that can not be solved by Toyota. Every time we complain, we were always told that bring the car in when the light goes on. The problem is when the light goes on it will be off when we get to the dealership. We noticed when the car reached approximately 98,000 miles. The cause of the on and off lights are unknown.

My dash panel warning lights 4 or 5 lite up, took it to a Toyota dealer, he put it on a computer and stated that, your catalitic converter, muffler and other parts need to be replaced. Took it to another mech. He put a pint of lukus gas treatment, told me to fill the tank with higher octaine gas and run it in 4th gear.

My passenger side power sliding door cable snapped on it, when I went to open it months back, the cable is hanging down on it and I havent been able to use my power sliding door in months! it snapped on me when it was parked and I had a load of groceries I hit the power door button and I saw something fall from the window and it wouldnt open or shut. I actually have to have the indoor light switch off because the door when I go around corners light will come on that it isnt properly shut! its a safety hazard that I cant afford to fix! it happened at 117,000 miles back in May 2018. I was told it was going to be $2,000! I was never notified of a extended warranty on these sliding doors! now im just past the mileage of 120K and 9 years" I bought a Toyota minivan in 2008 for safety for my family. I loved the power sliding door when I picked my kids up. This is wrong, many other people have had this same problem, and I never get a warranty slip on it, and if I wouldve known when it broke, it wouldve been covered. But now its too late"! thats not right!! these cables have obvious defects, and should all be replaced when this happens!!!

Dear madame/sir, I own a Toyota Sienna (2008). The driver side sliding door cable just got cut-off last week while my kid was trying to open the door and get in and the passenger side door moves very slowly. I went to the Toyota dealer(s) and they said they had a fix at no cost only for vehicles which are 9 years/120,000 miles and if the customer came with a problem (not a recall) and I do not qualify as it has been 10 years (how did Toyota come-up with this number?). I went online and found that many people have reported a similar issue and looks like Toyota did not take care of them either. From the dealer I understand Toyota was aware of the problem and did not take care of the issue or did not do enough to resolve this problem. I sincerely request you to provide necessary directions/action taken against manufacturer so that 1000S of customers like me will get their car fixed. Thank you for your valuable time

A cable on the passenger side door of my Toyota 2008 Sienna broke and started making a strange noise. I am unable to open the door fully and my children are unable to get out on this side of the car - a safety hazard.

I had trouble accelerating up a hill and stalling and turning off on the road. I took my vehicle to my Toyota dealership for inspection and was told that rodents or such type had chewed on the electrical wiring harness because of the insulation materials attractiveness. After been first offended, I then remembered seeing a squirrel near the vehicle I presumed innocently taking shade from the hot Florida sun. During that time I parked my vehicle in my driveway outside. I advised the dealership of this and they confirmed that indeed such animal would liking have chewed on the harness wiring causing the issue at hand. I paid out of pocket for this repair since I was told it was not under warranty. It has come to my attention that the Toyota dealership was aware of this type of animal and the attraction to the soy based insulation around the electrical wiring harness. There now are two class action cases regarding this matter with Toyota.

Powered passenger doors on both sides of the van malfunctioned and then cable system broke and locked the doors in the closed position. This happened one after the other in about a three-week period. The cable is clearly rusted and shredded on the one side. I cannot tell why the cable pulled out and stopped working on the other side. As I Transport 3 or more children at a time, it is a huge safety issue that the only way out of the car in case of emergency is through one of the front doors or the back trunk hatch. I have owned this vehicle since it was new and I am told this is out of warranty/isn't covered and will cost at least $6,000 to fix. I cannot drive the vehicle like this and I can't afford to fix it. I am apparently not the only one who's had this problem with the van, yet Toyota is doing nothing about it for their customers.

My Toyota seinna 2008, has been locking and unlocking while driving....for the past few months in 2016 my sliding doors and front passenger door lock up and will not unlock with my remote or any other way...I can unlock the front passenger door with a key, but there is no way to unlock the sliding doors...recently I had two friends riding with me...we got to our destination and I got out tried to unlock sliding doors with my remote, they did not unlock...my friend sitting in the second row seating could not get out.she is handicapped....I had to crawl through the rear door and help her up out of her seat and then carefully crawl on the floor of the van to the rear door and climb out.this is truly a safety hazard and cannot be dismissed....sometimes the doors will unlock and sometimes they won't.....so when I take it to the Toyota dealer it always seems to work for them......my van runs well and I have no other problems with it.I feel if the Toyota manufacturer can design computerized doors then they have to have a way to find and fix the problem.my first thought is, why did they not design key access to these sliding doors ? something has to be done to correct this problem.

The contact owns a 2008 Toyota Sienna. The contact stated that when the air conditioner was activated, hot air circulated throughout the air vents. The vehicle was taken to an independent mechanic where freon was added, but the failure recurred. The vehicle was taken back where it was diagnosed that the air conditioner O rings needed to be replaced due to a leak. The vehicle was repaired, but the failure recurred. The manufacturer was not notified of the failure. The failure mileage was 139,000.

Sliding door on our 2008 Sienna stopped opening or closing. We can not get in our get out off the car on driver side. We are glad it happened on parked position. It is not working electrical or manual mode. Toyota is asking about $1600-3000 for repair. We are trying to use the van with one sliding door and it is nor practical or safe.

Purchased 2008 Toyota Sienna new in August 2008. In November 2015 (90,000 miles) with vehicle parked, when opening the passenger side power sliding door, the cable snapped, binding the powered door's electric motor, and causing the door to be "locked in place" about 6 inches open. Went to driver side power sliding door, opened, children entered passenger compartment, and upon closing door this cable snapped, but didn't bind electric motor until the door had fully closed, causing the door to be "locked in place" in the closed position. Traveled home and children exited vehicle through front driver and passenger doors. The cables were cut between the electric door motor and the "C post" to get the doors "unlocked" and allow for manual operation. Examination of snapped cables revealed removal of cable insulation (likely due to friction/abrasion), which exposed the stranded metal cable to the environment, causing severe corrosion and eventual failure of the metal cable. Online research revealed many other 2008 and newer Toyota Sienna owners have had similar problems, to the point where a facebook page has been created regarding the issue https://www.facebook.com/Toyota-Sienna-faulty-power-sliding-doors-233250320033754/. further research revealed that Toyota has a warranty enhancement for this problem (no: Pol12-02), but it only applies to 2004-2007 model years. Whatever corrective action was taken by Toyota beginning in 2008 obviously has not remedied the problem. The power sliding door assembly required to repair these doors costs $500 per door (part numbers 69631-08030 and 69641-08030). To have a dealer make this repair costs $1,000 per door ($500 for the part and $500 for labor).

While passenger side visor is down smoke starts pouring out from under the head liner. When the visor is placed back in the closed position smoke clears out and stops. Per the mechanic, a short in the electrical system has resulted in a melted electrical board and the entire head liner and electrical board needs to be replaced. The visor can not be used or the short may start a fire inside the vehicle. The vehicle was in motion when this occurred. Van filled with smoke quickly. Had to pull over and open doors to clear the smoke.

My passenger side power sliding door mechanism is broken on our 2008 Sienna with 68,000 miles. The mechanism uses and electric motor and cable assembly to open and close the door. The cable has broken so power functions are gone and manual function is hindered from broken cable interfering. Toyota has extended the warranty for 2004-07 Sienna's with the same problem with the same part and part number? a internet search reveals this is a common problem and can affect the proper latching of the sliding door.
