2022 Toyota Redundant Sienna Problems

While driving at about 40mph on a city street I complete lost steering, brakes and vehicle control. I suddenly started severely swerving/ spinning. I suddenly had no control over the vehicle. The vehicle threw a bunch of codes at once including: anti-lock brakes malfunction, pre-collision system malfunction, secondary collision brake system malfunction, braking power low, parking brake malfunction. I tried to turn off and restart the car and it did not reset any codes. I have brand new tires on the vehicle and just had an oil change and check up two weeks ago. There was no reason for this to happen other than a complete and sudden safety failure of apparently multiple systems. Vehicle is currently being inspected by local Toyota dealer.

The 2022 Toyota Sienna temporarily accelerates or surges forward while braking, or has a momentary loss of braking / deceleration before it re-engages in braking.

Pre-Collision System Malfunction, Hybrid System Malfunction, AWD System Malfunction suddenly when restarting the vehicle. Towed to Toyota of Downtown LA dealership. Toyota of Downtown LA Service tells me that the CPU on my relative new Sienna 2022 was fried from jump start when Sienna starting-battery was low. It was done by a AAA professional, I doubt that is the reason for the fried CPU. I believe Toyota engineers would not design/allow the CPU vulnerable to being fried from a jump start. This is a horrific design flaw if it is this way. This happens now, just 6 months after the 3 year warranty coverage. Toyota of Downtown LA Service is telling me it is going to cost me $2900 to replace this CPU. I find this unacceptable.

The wiring harness connector for both lights has had water accumulate in the connector which causes the rear tail lights to fail. Both of my tail lights have failed, and the cause was corrosion inside the wiring harness connector. I had to replace the wiring harness and connectors on both sides, driver, and passenger And I had to pay out-of-pocket. The dealer said that this problem is common on 22 sienna's and I have seen other 22 sienna's with out their driver and passenger rear running lights burnt out.

Right after parking my 2022 Toyota Sienna XLE, I heard a VERY LOUD boom from overhead. It sounded like an explosion. Upon getting out of the car to see if something hit the car, I noticed the glass of the sunroof had a shattered pattern (but none of the glass actually came apart). My and my family's safety is at risk because at any moment, glass could shatter and enter the car. Fortunately, my moonroof cover is closed. Other people are at risk because if glass breaks off while I'm driving, it could hit other cars or pedestrians. I am writing this within 30 minutes of the explosion and have not taken it to a dealer, independent service center, nor has it been inspected by the manufacturer, police, insurance representatives, or others. There were no warning lamps, messages, or other symptoms of the problem prior to this incident.

seat retractor failure- white plastic part off and visible , seat is making popping noise when seat is being adjusted. Noticed this when i picked up from dealer after oil change. I feel this is a driving safety concern. Larry H Miller American Toyota (Albuquerque, NM) service manager states it's safe to drive, however I feel this is a huge safety concern. The seat was in working order did not have this issue during drop off of service. However I believe this is a failure on Toyota engineering. I would like some guidance on how to get this repaired as they want me to pay $2,000.

The driver side control panel trim keeps snapping off. I’ve researched it and it’s happened to others. It’s been repaired 3 times!

The contact owns a 2022 Toyota Sienna Hybrid. The contact had ordered the vehicle with modifications due to being a disabled veteran from a specialty vehicle modification for disabled persons manufacturer. The contact had picked up the van from a dealer and was driving approximately 60 MPH when the smell of something burning filled the passenger cabin. The contact pulled over and called the dealer who took the vehicle back and determined that the fuel line was rubbing against the rear passenger side tire. The vehicle was repaired. The contact stated that also the "check battery" light had illuminated, the light blacks out the entire instrument cluster and cannot be reset. The contact stated that he took the vehicle back to the dealer and they could not repair the warning light failure. The dealer had diagnosed that the main batteries were getting overheated making the vehicle dangerous to drive. The manufacturer had not been informed of the failure. The contact stated that the van modification facility had modified the vehicle with all of the defects and sold the van with the defects to him. The failure mileage was approximately 9,000.

Ever since a tire was changed on the vehicle, it has had a recurring error message that states there is a malfunction in the tire pressure monitor system. As such, I rarely know the status of my tire pressure as the system has the malfunction at least 50% of the time. The car has been in service 2x for this issue and they have had it for close to 30 days and driven it all over saying they needed to drive it to make the error go away. They have replaced the sensors on the tire, nothing has worked and the problem still occurs daily.

Vehicle will not start every single winter! Has been in the toyota repair shop multiple times. Told me it was possibly the kick sensors that are activated in the cold, stay on and then run battery dead. It is currently 20 degrees outside, but was parked in the garage all night, and STILL won't start in the morning! Completely unreliable. Nearest dealership is 1 hour away from me. Kick sensors were replaced last year, battery has been checked. Still happens. The vehicle is completely unusable and unreliable. Other issue- battery is in the back of the vehicle and you cant open the back door to access the battery to charge it! You have to get an external battery charger, charge front battery to open back door then jump back battery. If I was out and about I would have no way to do that. Absolutely unacceptable and a reoccurring problem. This needs recalled. Many others online report the same issue. Please respond.

When engaging the cruise control, the vehicle continued to accelerate even after I let off the button. During a trip with this vehicle on September 14, 2024, this vehicle did this twice. I have never driven another vehicle where this occurs. If this is supposed to be a "feature", it's unsafe and should not be legal. If it remains legal, there should at least be some kind of safety sticker.

Our 2022 Toyota Sienna would not start after arriving at a doctor’s appointment. Contacted active ToyotaCare for towing - no one showed up. Called a friend to jump start van; consulted the owners’ manual and performed jump. Van started but could only be driven about 100 yds in parking lot. Van stopped; multiple error codes showed up when trying to jump start again. ToyotaCare didn’t call again or show up so we ended up paying for tow service to the dealership - Haley Toyota of Richmond. Dealership checked vehicle; concluded the battery had an internal weld problem but that the jump start was not performed properly even though the manual was followed. There are no jump start instructions in the engine compartment. We were given a Tech Bulletin instruction sheet with more accurate information. We were advised the Engine Control Unit was burned out, causing all the error codes and would not be covered under warranty because “we” did not perform the jump start correctly. The cost of repair is almost $1100.00 but the battery, which started all the issues, is covered under warranty. The Tech Instruction sheet indicates to me that Toyota was aware of the inadequate jump start instructions and failed to inform customers of the possible issues. The Tech Instruction sheet we were given is dated April 6, 2022 - one month BEFORE we purchased the vehicle. The sheet lists all Toyota hybrid models as affected.

On May 18, 2025, 4:00pm, my wife was applying brakes to stop for a stop sign at a T-intersection. Suddenly, the car lurched forward and accelerated uncontrollably. Despite her attempts to stop, her vehicle crossed four traffic lanes, vaulted over curb, nosedived into turf, and then crashed through brick wall into a fire station. My wife was unable to brake and stop the forward progression of the vehicle. My wife steered to avoid hitting trees but could not avoid the brick of the fire station wall. The airbags did NOT deploy. My wife sustained back injuries and bruising of the front torso. Her right foot is bruised from pressuring the brake pedal. The vehicle sustained heavy damage as did the fire station.

Passenger air bag malfunction notification randomly going off (with and without items on the front passenger seat). I was told the dealership can’t diagnose it unless the alert is going off at the time the vehicle is dropped off.

The Entune 3.0 System governs navigation, calls etc. The system on my car has been replaced 4 times and still does not work. This is a life safety issue as the system grabs phone calls while driving without being able to answer. It also makes it frequently impossible to use hands free on the phone as it grabs calls. In order to avoid it grabbing calls I have to disable bluetooth on my phone which then causes my phone to not work in handsfree mode (ok google etc.) Furthermore the backup camera does not always work. Finally, a Toyota Service Manager told me in his oppinion 25% of the entune units are "bricked," non functional and need to be replaced. Toyota has fired according to him Panasonic as the supplier and now has a new provider.

When decelerating, particularly on hills or into corners, there is an intermittent surge that occurs after the brake pedal has been depressed. It feels as though there is a release of the braking action, this is unsettling as if you are starting to approach a vehicle or pedestrian, this sudden "delay" of braking could result in contact with other objects. We have changed our driving behavior as a result of this. We reported this behavior at 5000 miles and there was not a solution until last year. We were not notified of this, and our vehicle is now out of warranty. Toyota has released as of last year a TSB related to programming and we are going to pay out of pocket $300 this week to get that TSB applied. This doesn't seem fair to consumers. You can see this is not an isolated problem here: [XXX] , a 2025 and 2024. In both of those vehicles, this behavior is not present.

After starting the van, an error pops up: "SRS Airbag System Malfunction Visit Your Dealer." This occurs a day after turning the car on and off and driving for several hours. The next day, it may come back on, or it may not. I have taken it to a dealership, and they stated it was a firmware update they completed. After they updated the warning light, it came back on less than a week later.

The contact owns an Convaid Car Seat, Model Number: 3365, Model Type: Carrot 3, Manufactured Date: May 15, 2018. The car seat was being utilized in a 2022 Toyota Sienna. The contact stated that the release button on the crotch restraint buckle, where the two arm and chest belts buckled, were cracked into two pieces rendering the car seat unusable. The failure occurred inside of the vehicle. The child was not in the car seat at the time of the failure. The manufacturer was made aware of the failure. The car seat was not replaced.

While driving at about 40mph on a city street I complete lost steering, brakes and vehicle control. I suddenly started severely swerving/ spinning. I suddenly had no control over the vehicle. The vehicle threw a bunch of codes at once including: anti-lock brakes malfunction, pre-collision system malfunction, secondary collision brake system malfunction, braking power low, parking brake malfunction. I tried to turn off and restart the car and it did not reset any codes. I have brand new tires on the vehicle and just had an oil change and check up two weeks ago. There was no reason for this to happen other than a complete and sudden safety failure of apparently multiple systems. Vehicle is currently being inspected by local Toyota dealer.

Car only has 10K miles. It pulls to the right. We had dealer check tires multiple times, did alignment twice and yet car pulls to the right.

I have a Toyota sienna 2022 Limited AWD, not been driving much recently. The last time I drove was 2 days ago but local around 2 miles. Today I tried opening my doors, and there is no response at all. At first I thought maybe my key fob is dead, so I grabbed my spare and tried, nothing. Pull both my physical keys out twist and turned, still nothing. Called Toyota Roadside service and they said in that case they will have to tow my van to the nearest dealer, so it seems Toyota is aware of this issue. What is the point of the physical keys if they can't open your doors when your battery is dead? What if my kids are stuck in the car????
