2015 TOYOTA SIENNA Complaints

When vehicle is in reverse the rear breaks on passenger side start squealing and making a loud noise when applied specially when vehicle has been stopped for while however on occasion it does it every time you back up when applying break.

We recently had two Dunlop P 235 / 50 R 19 tires fail on our car. On 11/5/21, the front passenger-side tire tread and belt began to unravel while driving at freeway speed. This happened suddenly, with no warning lights, and we became aware of the problem when we heard a loud thumping noise from the unraveled tire striking the underside of the vehicle. We immediately exited the freeway, found a tire shop, and had the tire replaced. The following week, I inspected the other tires and found that the front drive-side tire was failing in exactly the same way. We immediately had that one replaced too. Neither tire shop that replaced the tires could identify a cause of the tire failures other than possible defects in the tires.

The contact owns a 2015 Toyota Sienna. The contact stated that the vehicle failed to start after several attempts. The contact stated that she was quadriplegic and was unable to exit the vehicle because the door lock switch was disengaged but failed to respond. There were no warning lights illuminated. The contact stated that she was able to jumpstart the vehicle with assistance. The contact then engaged and disengaged the door lock switch and she was able to exit the vehicle. The contact stated that she notified the modifier of the vehicle, but they said they could not assist with the failure. The dealer and the manufacturer were not notified of the failure. The vehicle was not diagnosed nor repaired. The approximate failure mileage was 48,000. The VIN was not available.

The vehicle rear sliding door had a recall. I had the recall preformed at Smithtown Toyota. After the correction was done. I continue to have same issues with the drivers side rear sliding door. Where it will not open when pushing the open button on my controls in the front. Or when my child 12 years old attempts to manually open the door. As this does not happen all the times. The dealer says they can not replicate the problem and it is working to manufacture standards. I spoke with Toyota corporate and they are aware of continued problems with the sliding rear doors. the have a customer support group, but I would have to pay for the dealer to inspect the vehicle. I have extended warranty so they said I wouldn't then have to pay. However every time you take it in with a problem they can never replicate the problem. They are not the only dealer with this response. It must be a set line throughout all brands as its always that answer until your warranty expires. When it expires then all of a sudden they can find all problems and fix everything.

The contact owns a 2015 Toyota Sienna. The contact stated while starting the vehicle he noticed that the vehicle was shuddering and shaking uncontrollably. The check engine warning light was illuminated. The contact attempted to restart the vehicle however, the failure persisted. The contact took the vehicle to an independent mechanic to be diagnosed. The contact was informed that the failure was due to low cylinder pressure on cylinder #6. The mechanic was not able to do the repair on the vehicle, so the contact took the vehicle to the local dealer who diagnosed and confirmed the failure as a misfire and low-pressure cylinder #6 and that the spark plug was damaged. The vehicle was repaired however, the failure persisted. The dealer recommended that the engine be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 87,000.

When I drive this van downhill on a curve not fast slower than 40mph, the antilock brakes engage violently and hard and jerky I do not have my foot on the brake when this happens. I'm not going fast. But the ABS is so violent it causes me to lose control of the steering. It happened 3 times in 24 hours and always in same situation. Only lasts a few seconds. Other Sienna owners have had same issues. 119k miles on the van. Bought it used. Had no idea. Of course dealership can't replicate the problem and won't help us. I'm scared to drive the car.

For at least 4 years, water collects in the driver side pillar and soaks the seat belt. Toyota tells me they have never heard of this problem, although I do see it on You Tube. I don't know if the water is damaging other components. But when I pull out seat belt water pours from the pillar and onto the floorboard behind driver seat. I keep a towel in van to keep water off driver and to mop up floor & pillar. The problem is ongoing. I keep a tarp over the roof when rain is expected.

We purchased Nokian WrG3 225/60 R18 tires as replacements for the original tires, because we wanted all weather capability. They were installed in November of 2016. One tire subsequently was damaged due to road hazard; was replaced with same Nokian tire. In August, 2021, the tires needed balancing. The dealer (same place we bought them) could not balance them because three of the tires had belt separation. I did not check tire serial number, but assume them to be the original three we purchased new. We are awaiting Nokian's response, as the tires are warranted five years from installation. It is unusual three tires would all suffer belt separation, all made at the same time. Logic would say it is a manufacturing defect.

I have a 2015 Toyota Sienna LE that I purchased new from the dealer. The original Michelin tires had excessive wear after less than 2yrs and ~28K miles. I replaced these with Continental tires(rated for 70K miles) and after 2years and at ~63K on the vehicle miles I had to replace those with General Altimax (rated for 75K miles). Each time tires were replaced it received and alignment. I now need to replace the third set of tires at ~88k for set number four. Additionally I had to replace the Rank and Pinion (Complete unit), both tie rods and both suspension control arms and ball joint assembly and a wheel alignment. Can is adult driven mostly in town but has one long road trip on it (6K miles). This will be the fourth set of tires on a vehicle with less than 100K miles along with 5-6 alignments. All tires have been maintained and rotated. This has to be a vehicle defect as I have multiple tire manufactures, all rated for more than double the tire life I'm getting. I have $2000 in tires so far (not counting the originals) $1250 in replacing the front end components noted and now have to spend another $1k on tires.

IN JANUARY 2021, WHILE SITTING IN THE DRIVEWAY AN EIGHT INCH CRACK APPEARED IN THE MIDDLE OF THE WINDSHIELD. THE WINDSHIELD WAS REPLACED IN SEPTEMBER 2020 AFTER PURCHASING THE VEHICLE AS A REPO. THE WINDSHIELD THAT WAS REPLACED WAS CRACKED THE ENTIRE WIDTH OF THE GLASS IN THE EXACT SAME PLACE WHERE THE NEW CRACK HAS APPEARED. THE VEHICLE WAS TAKEN TO THE REPAIR SHOP AND IT HAS BEEN DETERMINED THAT THERE IS NOT ENOUGH SUPPORT FOR THE WINDSHIELD BUILT INTO THE FRAME CAUSING THE DAMAGE TO REAPPEAR. SINCE THEN THE CRACK HAS CONTINUED UP THE WINDSHIELD AND IS NOW APPROXIMATELY 14 INCHES.
