2008 Toyota Sienna electrical problems

Filed Jul 15, 2023 · Electrical, Steering · CA

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.
