Owner report 11423107 · 2021-07-01 (July 1, 2021)

Van has just over 5k miles. Multiple warnings occurred while at speed on a highway. Primary warning was 'Low Brake Power' and braking became extremely touchy as it seemed to utilize the emergency brake as a backup. This extreme braking is hazardous and could result in an accident caused by braking too quickly - with a possible rear-end collision by traffic to the rear. Additional warnings/malfunctions were listed as well, due to the low brake power: LTA Malfunction (Lane keep assist), Automatic Emergency Brake Malfunction, Parking Brake Malfunc…

Owner report 11426402 · 2021-07-26 (July 26, 2021)

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.

This alone could have caused an injury or accident.

Owner report 11523611 · 2023-05-24 (May 24, 2023)

The vehicle has had rocks get in the suspension 4 times so far which creates loud clunking noises and can cause a noticeable feel in the steering. The most recent time, after the rock entered the front end, the brakes were soft and required excessive pedal force followed by a clunk before the brakes abruptly applied. I like on a paved road with a rock driveway and it seems like the shielding for the front end is inadequate. I have friends with a 2022 sienna that live on a gravel road that have experienced similar issues.

Owner report 11582842 · 2024-04-14 (April 14, 2024)

This incident had happened twice in the last 30 days. I have been stopped, then starting to accelerate after a stop sign, I push on the accelerator and the vehicle slows down, as if it’s losing power for about 5 seconds. I do not release the accelerator and after the 5 seconds of what feels like no power, the van begins to accelerate like normal. This poses a severe safety risk while crossing intersections when you believe your vehicle should respond when pushing on the accelerator. I did not have any notifications pop up on my van, I was in …

1st. Brake sometimes get very stiff can’t press down and becomes normal after a few seconds or a few press on the brake pedal. (5 months) 2nd. A lot of wind noise coming from driver side windshield starting at 65mph. Complain to 2 dealers both said they test drove the same car but I don’t see any other Sienna around. They lied (1st day I took possession of the car) 3rd. The middle row seat rail are very hard to slide back and forth. (1st day)

After the vehicle has been parked for a while, after starting the car the brakes give the following intermittent behavior. When releasing the brake pressure gradually, the vehicle will not move until the brake pedal is fully released. The vehicle then lurches and rolls backward quickly. Additional pressure then must be applied to stop the car. The car should start to move when the brakes are gradually released and not wait until the brakes are fully released. This happens almost every time I start the car. It is a recurring problem.

At 7:35am on 7/20/2022, I was traveling south on Clementa Ave SW in Monticello, MN. The conditions were dry and the sun was out. As I approached the intersection of 127th St NW, I began to slowly press the brake pedal. The vehicle started slowing down, but approximately 5 seconds after pushing the brake, the vehicle automatically let off the brakes, the vehicle lunged forward for about 1-2 seconds, even though I was continuously pushing on the brake pedal. The vehicle’s brake system then re-engaged and the vehicle stopped. This is not the …

After the vehicle has been parked for a while (>1 hour in my experience), upon startup, when reversing down a hill, the brakes give the following intermittent (maybe one out of four start ups) problematic behavior. When releasing the brake pressure gradually, the car will not move, until suddenly it lurches and rolls backwards significantly, the pressure on the break feels like it is reducing and the brake stroke length releasing. To stop the car rolling backwards you need to push down several extra inches on the brake to get it to stop. I have…

While traveling in the far left lane of a four lane highway with a speed limit of 70 mph my car started to fish tale but I was able to control it. The cars behind me saw the blowout of my rear passenger tire and slowed down so that I could move to the far right breakdown lane. No warning light came on at any time to alert me of any problems with any of the tires. I always maintain the correct tire pressure. I had a tire company replace all four tires because I was afraid of the other three tires doing the same thing. When I picked up my ca…
