Vehicle Speed Control Problems of Toyota Sienna - part 2

Sometimes when I take turns in my Sienna, the vsc starts going off and braking individual wheels without my control. This happens unexpectedly on highway bends at speeds of 60+ mph and it is difficult to control the car and keep from swerving into another lane. If the roads were icy when this happens, it would probably cause a dangerous accident. Toyota has a technical service bulletin for this, but not a recall - which it should since this is a significant safety issue. The TSB is br008-04. There are many others experiencing this same issue: https://forums. Edmunds. Com/discussion/13855/Toyota/sienna/vsc-sudden-activation-2004-Toyota-sienna.

Shifter broke at 55 mph wouldn't stay in 5 gear, was easily moved to r, n, and flopped around! won't stay in 4 now when used either, or park unless held when turning car off. No warning, shifted down for a hill, speed limit change, and corner in neighborhood as usual, no lights on in car. Just happened but upon research, have found many others with this problem online, same veh and same kind of miles. Toyota knows but won't recall their broken plastic piece and no notification to consumer.

This is to advise you of a safety issue with our 2013 Toyota Sienna xle minivan having a v6 (3. 5l) engine. Our vehicle currently has 118,169 miles on it and has been well maintained. This vehicle was purchased new and is operated primarily in florida where we live. Over the last 6 - 10 months on three occasions our Sienna minivan suddenly lurched forward as the engine revved up. On all three occasions, I had to take quick action and with significant force press the brake pedal as well as place the minivan in neutral and then into park in order to stop our minivan from surging forward and hitting the car in front of me. On all three occasions, my right foot was on the brake pedal when this occurred and on two of the three occasions, our minivan was slowly accelerating from either a stopped position or a very low speed (5 mph or less). On one of the occasions I was approaching an intersection with a stop sign and our minivan was decelerating to a stop when the engine revved up and the minivan surged forward. This occurred as our minivan was going approximately 5 - 10 mph. There were no warning lamps, messages, or other symptoms prior to any of these incidents. I have reported this condition to our local Toyota dealer but they said they could not duplicate the issue during their test drive. This is a serious safety condition and one that could result in a serious accident with injuries particularly if the driver is not quick to react to this unexpected condition.

We were driving down the freeway when we got rear ended hard by a large pickup. Then we lost electrical and engine power. The brakes stopped working. The hazard lights stopped working. Luckily we were able to coast to a complete stop as there was no way to stop the car. The police came and took a report. Then the car was towed to a body shop. We're awaiting the insurance company adjuster for inspection.

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.

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.

2008 Toyota Sienna. Driving down steep right turns, vsc light comes on, urgent beeping alarm and tires grip and grip vehicle brakes going 20-30+ mph on dry road. Very scary and dangerous, and has continues repeatedly over the past year on curvy right turns. Local mechanics don't know what is wrong with the vehicle. Many Sienna owners have similar problems listed on carguru. . Read more...

While reversing out of a parking spot, felt the van "jumped" then accelerated on it's own while in reverse swiped a parked truck, and did a half circle into the drive-through of a parking lot only to stopped when it hit another SUV. I felt I had no control of the van while this was happening.

Brakes have been replaced, and checked several times make a loud grinding noise in wet weather when backing up and sometimes when applying pressure while driving also a 🔊 noise and brakes seem to slip have had to pull over because it scares me can not find anything wrong but continues to persist. Both in highway driving and regular street driving.

Car speed varies when doing a moderate speed example 40 mph sometimes feels like its engine slips and speed slows car jumps forward feels like engine slips or gear shifts. Engine bogs down or sometimes revs up a little. . Scares me sometimes but no choice but to drive.

While on an on-ramp; the vehicle at about 35 mph started blinking the slip light and slowed the van down, also causing I think the brakes to engage with force. Happens while driving normally and on ramps. I had the rack and pinion replaced and still has done this.

I had torque converter clutch pressure control solenoid control circuit and when I rich 85 speed the car check and my friend have the same car sam model he had the same issue.

The vehicle stability control will unexpectedly engage in instances where it shouldn't activate. The most common is a long, slight curve on at freeway speeds on dry pavement. The second most common scenario is accelerating to enter the freeway. When vsc engages, the vehicle will lurch to the side it was activated on and curtail any acceleration. This makes the vehicle hard to control when on a freeway curve and when attempting to accelerate to merge onto the freeway, causing unexpected motion that is a hazard to remaining on the road or causing the vehicle to be in an accident with other vehicles. There is no indication that there are malfunctions in any system that would cause this to occur. Note: mileage on the odometer is ~170,000 miles.

Traction control and abs activated on dry roads acting like the vehicle thought it was going into a slide/skid. This could have caused a serious crash! ## #vpic# 1 - check digit (9th position) does not calculate properly; 2 - VIN corrected, error in one position; 14 - unable to provide information for all the characters in the VIN. #vpic#.

When pressing the brake the engine revs suddenly and to very high rpms and you have to press down on the brake and/or throw car into neutral/drive and then eventually the issue resolves. Happened yesterday when reversing very slowly out of driveway--was pressing brake (not accelerator) and suddenly the engine got very loud and was revving up. Pressed brake hard and thru the car into park and pressed the accelerator and the engine went back to normal. Very scary. Has happened several times before and fortunately we have not run into anything and the car has not taken off at high speed.

Continuous issues with traction control system almost daily. Any time vehicle veers towrds the right anti-slip indicator light, alarm sounds and abs system activates. This happens almost daily, on dry roads, going downhill or on a curve, even while switching lanes now. This happens above 20 mph. Driving becomes stressful and worry-some when alarm begins to sound and dash light come on. Fear of losing control becomes great, fear for your passengers safety as well as other drivers safety becomes real. During the past 3 months there have been 5 separate incidents in which the vehicle has lost acceleration, pulls steering in one direction and sudden break lock occurs. 2 of which took place on the freeway on ramp at a speed of 35mph, 1 driving downhill, slightly towards the right, at a speed if 20mph and the last 2 while switching lanes, 35 mph. Vehicle began losing power and slowing instead of increasing speed. There are many complaints regarding this issue with many drivers in many areas. Why isn't this being investigated?.

At speeds of anywhere between 30-60 mph, traction control system engages when turning slightly left. Alarm comes on, brakes are automatically applied. Very dangerous.

Car accelerates when trying to stop/ pressing breaks.

When driving at speeds of 38 mph or more and turning the steering wheel/tires, the vsc warning alarm will go off. When this happens, the cars automatically brakes. This happens when there are no problems with the driving conditions. The severity of the braking and length of alarm vary. It is especially problematic on tight turns. It does not matter whether you are going uphill, downhill, or turning on a flat road. We do not know what is causing this unsafe issue. We have tried turning off the trac. It made no difference.

Driving on the highway, let off the gas though kept accelerating, braked as hard as possible without any effect, shifted to neutral and continued to accelerate.

Tl- the contact owns a 2006 Toyota Sienna. The contact stated that while coasting with traffic, the vehicle's accelerator pedal suddenly floored causing the vehicle to accelerate at high speeds. The accelerator pedal remained down. The contact attempted to press the brake however the vehicle did not stop.

When driving under normal conditions the vehicles' vsc will engage. The dashboard lights go off, there is a loud interior beeping sound, the abs engages, the car slows down drastically at once. The roads are dry. At first this happened while driving normal speed exiting or entering an hwy off/on ramp. Then happened yesterday as I was driving on neighborhood streets at about 25-30 mph. I could hear a rubbing on the back tires as if the brakes were on.

I was turning left on country road at 25mph the car decelerate and yellow warning came on the dealer said the car thought it was going to roll over they did the soft ware up date the car still decalrate yellow light come on most of time when starting up.

When coming to a stop going about 5 mph towards a stop sign, my van accelerated into traffic. Because the van jolted me into oncoming traffic, it almost caused an accident. It doesn't seem to matter whether I am braking or coasting, the van will accelerate uncontrollably. I have two children and not only am I putting their lives at risk, but mine also. I am not able to drive this vehicle due to how dangerous it is.

On a snowy Saturday morning, my husband was slowly (driving less than 5 mph) pulling into a parking spot while braking. As he shifted into park, the vehicle suddenly revved and accelerated over the five inch curb and hit a building a few feet in front of the car. His foot remained firmly on the brake during the incident. Although the vehicle had come to a complete stop once it hit the building and was put into park, the engine continued to make a loud revving sound. The revving did not stop until the vehicle was turned off.

From driving normal speed, car cap out at 20 mph at highway. Almost got into wreck. Check engine light came on as is happened. I took it to auto zone . Manager checked and said it happened to his 2014 corolla, Toyota covered variable transmission celenoid under recall. He said to call Toyota or dealership. Dealership is saying, there is no recall for this kind of safety issue.

Traction control has randomly engaged 4 times in the past week, at speeds as low 35 mph and on the highway at 65 mph. Pavement was dry and we were driving straight, not turning. Braking is applied causing temporary loss of speed and pulling steering to one side for about 1-2 seconds. Control returns and trac control light continues to blink. Does not result in an error code.

The van struggles to accelerate. There is no way to turn off eco mode. No button is available. Van struggles to go up hills , excelerate thru intersections and always hunting for gears or stuck in a gear and sounds and acts very heavy on power train end. There is an option to turn off eco light. Turning off eco light does nothing but hide the problem. We need an option to complete disable eco mode with update or with a button.

I was driving 65 mph on the highway going straight on dry pavement and suddenly a buzzer sounded, the vsc light came on, and the steering wheel and brakes were taken over by the vsc system and the car started weaving out of control. I could not steer or break the car. The situation is unpredictable. It easily happened on curvy or bend road and has happened 3-4 times in this year. It is scary.

I was driving down the street and then my car lurched forward, the engine revving up. It is a 2013 Sienna xle v6 & it had 113,000 miles on it. I had to stomp on the brake to get it to stop.
