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.
Loud noise from the rear end, diagnosed to be a viscous coupler bearing malfunction by my mechanic. Total cost of repair is 2428 dollars.

To cite a transmission mechanics who have experiences with the rav4/sienna rear differential issues. . Read more...
I was driving from toronto to virginia on 23 Dec 2020 and refilled gas in springfield NY walmart gas station to refill the gas. When I entered bedford PA turnpike, the car sounded with different sounds from engine on the ramp when entering the 70/76 freeway. When entered to virginia from maryland border after potomac river crossing on highway 15 , the car suddenly stopped while driving at 30 mph and pulled the car to the side of the road slowly and when I restarted the car, it started normal and drove till chantilly virginia without any stopping. But the engine gave me different noises.
Viscous coupling bearing making significant noise. Potentially hazardous if the issue causes the drivetrain to lock up.
Began hearing a loud whirring sound from rear of car when car is in motion. Got louder over time. Our regular mechanic could not diagnose the noise. Toyota dealership finally diagnosed as a failed electromagnetic rear coupler. Suggested we not use 'cheap tires. ' we never have. We actually went through three sets of the recommended 'run flat' tires in under 75,000 miles. As you know, these are not cheap tires to replace. Cost to replace coupler is incredibly high - should be covered under warranty, as a google search and discussions on Toyota chat sites tell me this is a common problem.
Electromagnetic coupler on awd Sienna, it seems like a super common problem that costs ~$2,500 us to fix and starts around the 100,000 mile odometer reading.

I pulled into a relative's gravel driveway which has a very large parking area to the side. I pulled up to about two feet from their grassy area, got into position to back up into a parking space, stopped, and put my 2011 Sienna into reverse, and as soon as I gently touched the excelerator to begin backing up the van sped forward at a high rate of speed crashing into and over an 8 inch railroad tie that had a steelbeam on top that separated the driveway from their yard. I had to slam both feet onto the brake to get it to stop which it finally did. I thought I had not put it in reverse but I looked at the gearshift and it was indeed in reverse. I jiggled the gearshift to make sure it was secured in the slot and it was. I then put it in park and sat there for a minute or two trying to gain composure trying to figure out what just happened, I was in shock as nothing like this has ever happened to me before. After that minute or two I decided I couldn't let the vehicle sit there and needed to move it. Scared, but I put it in reverse again, ready to pounce on the brakes with both feet and barely touching the excelerator I started moving in reverse. It was working fine then. I then got out to check for damage and the bumper on the driver's side was damaged from the impact. The airbag did not deploy, I was not hurt however had any of my relatives been in that area at that moment it could've resulted in an injury or fatality. I reported what happened to the local dealership where I bought it and then to Toyota USA as instructed in the handbook. Now I'm reporting it here. Am awaiting contact supposedly within the next day or so to see what Toyota intends to do with the Sienna. I will not drive again it until the reason for this defect is found and fixed and damages repaired. The outcome will decide whether I will ever be a Toyota customer again.
Hello, I own a 2011 Sienna le v6. In cold weather, it has a problem when braking where the vehicle lurches forward as it comes to a stop. The dealer drove the car and noted no issues. However, as you can see on this internet thread, many other owners have the same issue. . Read more...
Hello, I own a 2011 Sienna le v6. In cold weather, it has a problem when breaking where the vehicle lurches forward as it comes to a stop (a significant increase in rpm is seen just as the vehicle is about to stop). So much so that it seems as though it's giving itself gas (increased rpm) and driving itself, creating a hazard. I can literally take my foot off the brake pedal and the van will increase it's speed to about 35mph with no input from me in regards to the gas pedal. After warming up, the problem does tend to fade away. But the warmup period, especially on cold northeast days, could take as long as 20 mins. And 8 miles of city driving to occur (and this is after a 5 min. Parked idle warmup period), and even then, the van still exhibits this revving issue somewhat, just not as significant as when it's in the warmup stage. On my first complaint last winter, the dealer changed out the thermostat and considered the problem fixed. However, the van continues to show the same problem this winter. As you can see on this internet thread, many other owners have the same issue. . Read more...
The contact owns a 2011 Toyota Sienna. The contact stated that while driving 65 mph, the vehicle lost power and decelerated to 25 mph before stalling without warning. The contact was able to restart the vehicle but the vehicle would accelerate over 5 mph. The vehicle was taken to the dealer and was test driven. The dealer was able to recreate the failure but the vehicle was not repaired. The VIN was not available. The failure and the current mileage was 16,000.
Vehicle would expectedly slow down when you accelerate. The loss of power would last between 2 to 7 seconds. I have already taken the car to the dealer since the 15k-mile service. The dealer could not find anything. Nonetheless, the issue is still occurring on a weekly basis. This is a very serious hazard. Affected vehicle could get rear ended as it accelerate from stop lights when it suddenly slows down. What's worse? imagine your family in the car when you want to make a left turn, you press the gas pedal to accelerate, but it slows down before you can clear the on coming traffic. I hope Toyota is listening to this!!! this defect could have very dire results. I have found similar complaints in various forums online. I am certain more people are experiencing this and don't know where to report it. Nhtsa, please request similar complain data from Toyota dealers about this very dangerous defect.
The car accelerates very rapidly in reverse after a cold start. A morning a few days after buying the car, I started it up, shifted into reverse, and slowly released the brake pedal. The car began accelerate backwards so rapidly that I thought I must inadvertently put my foot on the accelerator. I pulled my foot away from the pedals but the car continued to accelerate. I shifted into park, but before there was any change in speed the car crashed into my neighbor's car across the street, causing over $5,000 in damage. If there had been someone standing across the street, it would likely have been a fatality. I contacted Toyota and they sent out a corporate representative to examine the car. He acknowledged there was rapid acceleration in reverse, and stated that was "normal" operation for the car after a cold start, and that it would be even faster in cold weather (we live in southern California). He stated they had increased the car idle speed after cold starts for pollution control purposes, and this was the result. I carefully reviewed the owner’s manual and inside of the cabin for any warning about rapid acceleration in reverse after a cold start, and there was none. I have always been a careful driver who has maintained a good driver discount, and nothing remotely like this has ever happened to me before. At the very least, because the company is aware of this issue they should prominently provide warnings to new car buyers and owners. I am concerned that this is a design defect will result in injury and death if not addressed promptly.
