Toyota Sienna warning lights comes on

Filed Feb 6, 2025 · Acceleration, Brakes · MD

I have had the traction control go on while driving on the highway even when I turn it off. Sometimes the VSC and TRAC OFF lights go on while driving. The roads are dry. Whenever I take it in to the mechanic, all the lights are off. They pulled a zero calibration code and recalibrated. It still kept happening. Then I was driving around a curve on highway speeds when the traction control light went on and the van suddenly braked on its own and I almost lost control. The tires are new and the roads were dry.

I was driving my 2017 Sienna on 5/10/2022 and was approaching a roundabout. As I was going thru the roundabout, my van stalled. I coasted into a gas station. After a few minutes I notice smoke coming from under my hood. I popped the hood and noticed the smoke was coming from the air intake. We called AAA and they towed it to the dealership we bought it new from and had all services done at. The next day we authorized them to do a diognostic on it where they found a burnt airfilter and melted housing. Heiser Toyota in Milwaukee WI has not repaired the van yet and we wanted to talk to Toyota customer service and your office to see what we should do. We called insurance and a claim has been started - not sure if they have inspected the van yet. It is available for you to inspect. All warning lights were on when it stalled. There was no power loss or any warning before it stalled.

Vehicle stopped abruptly with a shake while reducing speed at a traffic signal. I was in the middle of the road. A mild burning smell came out from the hood. The car was serviced one month back and as part of it they did 128 point( do not remember exact number ) and all reported issues were fixed. Around $1000/- was spent on the car. Since battery was just 1 year old, I did not expect a problem with the battery as well. Still I switched off all lights and tried to restart. There was no further response from the vehicle. I was blocking traffic from behind and police came to control traffic. Only option was to tow the vehicle. I took it to the same toyota authorized service center where I did the previous service ( I had purchased the car from the same dealer ). Next day toyota service staff called me and asked details of what happened. By evening they said that some spring break in cylinder 4 which clogged at some other part within the engine. In the process, there are scratches in other parts and the engine oil was filled with metal parts. Senior technician said this is a major issue and they have invited toyota field engineer to come and inspect the engine and associated issues. Preliminary assessment is that the engine might need a replacement as changing few parts may not be sufficient to keep the vehicle safe back on street. Incident happened in city street and when the speed was lowered to 20. Today is monday, but toyota dealer who is doing the service has not updated me yet with the magnitude of complete problem nor the time they need. I am heart broken to hear that the rough order magnitude cost to fix the car is between $18k to $20k.

Was driving home from running errands, about a 4 mile drive at 35 miles/hr. At a stop light there seemed to be some sort of electrical surge. All the dashboard lights flashed and the vehicle turned off. I was able to put the car in park and restart it. There were no warning lights on after restarting the engine, so I assumed it was a fluke and continued on my way home. A little further down the road at another stop light it happened again. I pulled into my driveway and started to unload my car when I noticed smoke emanating from under the hood. I opened the hood to discover a small fire coming from a large group of wrapped wires behind the battery. I was able to put it out quickly with a fire extinguisher, but the car is completely dead and the entire electrical harness needs to be replaced as well as some other nearby parts. This vehicle was well taken care of. There is just under 65,000 miles on it and I brought it in for it's 60k maintenance 6 months ago (6/11/18). At that time they also took care of the recalls for the passenger side airbag and the power sliding doors. Since I was able to contain the fire quickly, this vehicle suffered minimal engine damage, so I'm wondering if it should be used for investigation purposes before repairs are made as it appears this may have happened with other toyota siennas that suffered much greater damage.

Brakes locked up while trying to leave a parking lot. Many warning lights came on including vsc, ABS, and traction control and the computer said needs immediate service. The toyota service manager said they've never seen this and that the actuator needs replaced. I've noted that there are 2 other instances of this issue and hope that this safety issue will be investigated. The federal safety agency campaign number: 14v054000 that discusses: "an electrical component within the actuator may experience an increased resistance resulting in the illumination of various warning lights, including those for the vehicle stability control (vsc) system, antilock brake system (ABS), and traction control system." I've had this happen three times over the past four months. I've taken it to the shop and they've reset the code and could not find the issue. It keeps coming back. I believe the 14v054000 needs to be expanded to include my vehicle

While driving on the nys thruway with the cruise control activated my van came to an abrupt stop on the thruway. There were no vehicles in close proximity to my van that would have activated the radar cruise or the autonomous emergency braking system. After the abrupt stop all the lights on the dash were lit up ie: brake, ABS, pcs, slip indicator light, and master warning light. When I reached my destination I was unable to open the doors of my vehicle. Someone tried to open the doors from the outside of the vehicle and they were unable to open them as well. I brought it to the local toyota dealer and they could find nothing wrong. The above lights have lit up on several occasions however the dealer could find nothing wrong. There has been a previous complaint for the same behavior on 6/6/15 reported to toyota for the same make and model as mine a toyota sienna premium and they have not been able to get toyota to act on it.
