On October 15th at approximately 3:30 pm (ct) my 2014 Toyota Sienna was parked in my driveway with the engine on, unattended, when it moved forward up the slight incline of my driveway, struck another vehicle that was parked in the garage and kept moving forward until it struck the front wall of the garage. Prior to the accident, I had reversed the van out of the garage and left the van ignition on and in park as I exited. I know for certain that the van was in the park position since the automatic locks let me exit the vehicle without having to manually unlock them and the alarms did not sound as I exited. The van also did not roll forward ir backward as I exited. I then walked in front of the van to enter my house through the garage. I was in the house for less than 5 minutes when I heard the loud crash of the van striking the garage wall. My Toyota Sienna was manufactured on June 6, 2014. After the accident I discovered there is an active recall (recall: Transmission shift cable/rollaway/FMVSS 102) for an issue that causes rollaways effecting cars manufactured between June 17, 2014 through June 24, 2014. I took my van to Toyota expecting my issue to be related to this recall. Toyota had the black box inspected and the transmission inspected and determined they were not liable since they were not able to replicate the issue and did not find any defects. When I took my car in originally the technician stated that there was not a good way to determine if the shift cable was defective and they were simply replacing the part as part of the recall, which my car did not qualify for since it was manufactured 11 days prior. A car should never move itself from the park position and something has to be faulty with the car in order for it to do so.

After about 60,000 miles my check engine light illuminates with code P0012 every 1,000 miles and when I take it to technician they find nothing wrong after resetting. Then again it randomly appears and has been doing such for the last 10,000 miles. Frustrating. Also the front brakes squeal everytime I touch the brake pedal regardless of which pads I use or if they are new or used.

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.

All of the sudden, after a long drive on highway, I parked and fuel my car and my car would not change gears properly or very sudden burst then stuck in gear, then after little while I stop on the side and now it won't drive or reverse or sometimes won't go park.
