Anyone: In 2013 I bought a new Toyota Sienna from Fiore Toyota in Hollidaysburg, PA. It was advertised with a lifetime engine and powertrain warranty. I thought that I had made a wise purchased. Fast forward to 2022. In early June I noticed a loud humming from the rear differential area and since I had a family vacation planned with my son’s family I decided to take it in for diagnosis to my local dealer, Colonial Toyota of Indiana, PA. They said that it was the electromagnetic control unit but could not get me in for over a week and that it was not advisable to drive long distance. This resulted in my rented a replacement vehicle – an unanticipated expense. When I returned I took the vehicle into Colonial on July 7th and asked if the part would be covered under the lifetime warranty. They said they would check it out. There were several slow responses between the garage and the warranty company. Requests for additional service records, VIN numbers and what not. Meanwhile I am without a vehicle. Colonial had said that the part should be covered under the contract. Also Colonial’s lifetime warranty was a different company than Fiore’s insurer. Who knew? I had assumed that it was all a Toyota thing. Meanwhile after 8 days of no vehicle and another trip to Colorado approaching, (Granddaughter living alone while her husband is deployed in Poland.), I pulled the trigger and said fix the vehicle as I needed it. My thoughts were that it was a Toyota vehicle, serviced by Toyota “certified” techs at a Toyota garage what else would I need? The day after repairs were initiated, the warranty company says that they will need a 3rd party inspection to verify the defect. Just reinstall the broken part so they can hear it and then reinstall the new part or no coverage. Also this was to take place after I should have been half way across the country. Needless to say I didn’t do it. What good is a warranty that doesn’t trust Toyota techs? Out over $2500

Starting about two years ago, the traction/ABS lights come on between 20-35 mph on a gradual curve or randomly while driving. The brakes come on, like an ABS event, even though the brakes are not applied. The car will jerk to the right or left and chatters/vibrates. The mechanic said the brakes, tire wear and pressure, and suspension are all in very good condition and there are not traction control or ABS codes. This does not appear to be normal wear and is dangerous. We can only drive it on short trips for fear of getting in an accident. I decided to look online and found that hundreds of Toyota owners are experiencing the same symptoms. (https://www.cargurus.com/Cars/Discussion-c9152_ds656326). Can anything be done so that Toyota will come up with a solution? Thank you.
I was gonna make a U-turn at the end of the road and then the steering made a cracking noise. The steering shaft has been replaced 3 TIMES and it still happens. So much for Toyota Reliability.....................
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.
After a big snow storm I cleaned the car off and warmed it up, then tried to open the passenger side power door from the inside side with the button. The passanger side would not open (driver's side did) so I tried to open it manually from the outside and then the inside. It would not open at all. Then as I was driving, the car …

After a big snow storm I cleaned the car off and warmed it up, then tried to open the passenger side power door from the inside side with the button. The passanger side would not open (driver's side did) so I tried to open it manually from the outside and then the inside. It would not open at all. Then as I was driving, the car started beeping and the 'door open' icon lit up on the dashboard. I stopped the car and again tried to manually push the door shut as it appeared to be slightly ajar at this point. It seemed to close but the light and beep stayed on for my 10 minute drive home. When I got home I inspected more and noticed a wire for the power door had snapped at some point, I assume from the cold because it was operable the evening before. At this point I cannot open that door manually either, it is completely stuck shut, which I feel is a safety issue as my kids only have one point of egress. I did some research and this seems to match the description of one of the recalls but I was told my vehicle was not included based on the VIN #.

A few days ago the seat belt sensor would continue to beep and blink even after the seat belt was fastened. Then, on Friday, December 24th, 2021, a piece popped out of the seat belt latching mechanism on the driver's seat. Now it is difficult to get the seat belt to latch, and I am unsure that the latch would hold if the vehicle was in an accident that could cause serious injury to the driver. This is available to be inspected upon request. I haven't taken this to be looked at yet, but would like to know if this is something that I would have to pay for or if the manufacturer would cover the cost of this repair.

SRS Airbag check issue. Last few days, my car has been showing following symptoms 1) Day 1: SRS airbag check warning is flashing on the display. The passenger airbag is always OFF regardless of the passenger being seated or not. 2) Day 2: SRS airbag check warning goes away, but passenger seat airbag is always ON regardless of anyone sitting or not. Also the seat belt chime is sounded for the passenger seat. 3) Day 5: SRS airbag check warning comes back and passenger airbag is OFF. (same as Day 1). The auto mechanic says there is a code about Occupant classification system that is malfunctioning. Dealer wants to charge me a lot of money just to get it inspected and diagnosed. The car has not been in any collision. This seems like totally Toyota's design and part reliability issue. In no condition the driver or passenger safety should be compromised in such manner. Yet Toyota dealership is not standing behind their mfg commitment to safe driving experience.

1EA21002 · Desiccated Air Bag Inflator Rupture
Opened Sep 17, 2021 · No close date supplied
Status: open (inferred from source dates) · Air Bags:frontal:driver Side:inflator Module; Air Bags:frontal:passenger Side:inflator Module
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.

These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.
Air Bags:frontal:passenger Side:inflator Module
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants.
