2015 Toyota Sienna Problems

What owners report

Owners of the 2015 Sienna most often write about the power sliding doors: doors that stop and reopen, fail to latch, or open on their own, sometimes while the van is moving. Complaints also cover the dash and infotainment screen resetting or going dark while driving, a dimly lit analog speedometer, faster-than-expected tire wear, and occasional brake pedal or fuel pump problems. Some reports come in at low mileage, others appear much later in the vehicle's life, and several involve converted mobility vans.

   Power sliding doors stop short, reopen, or drift open

   • 66 complaints (28%)
   • median 30,000 mi at 2.7 yrs old (38 state mileage)
   • 3 mention a crash, fire or injury
   • filed 2015–2026

   Owners describe both sliding doors behaving inconsistently: a door closes partway and reopens, refuses to latch fully, or opens by itself while parked or while the van is moving. In some cases the doors had to be switched to manual to close them. Dealers replaced door motors or performed the recall repair, and some owners report the problem returned or the door no longer closed correctly after the work was done; parts availability for the recall was also a repeated complaint. Reported from a few thousand miles up to about 51,000 miles, in both parked and moving situations and sometimes more often on an incline.

   Recall 16V858000

   What to check: Cycle both sliding doors repeatedly with the engine off and on, on flat ground and on a slope, and confirm they latch every time. Ask whether recall 16V858000 was completed and whether any door motor or cable has been replaced.

   “After we got the recall with the sliding rear doors fixed, the passenger sliding door won't close anymore. It will go so far and then beep and open up again. I feel that it's a major safety issue and it needs to be addressed. After having the car for only 3 years, we shouldn't be having these kinds of problems with it.”

   NHTSA complaint #11110822, filed 2018-07, 39,096 miles

   “My 11-year old son got out of the front passenger side of our staitionary minivan (in park but running), for me to drop him off for a cello lesson. He opened the rear passenger side sliding door to get his cello out. It wasnt opening easily, so I almost simultaneously pushed the button above me on the console. At that point the door started to close on him. It did not stop closing and was pressing him into the door frame. I didn't realize what was happening, and he was too shocked to scream. …”

   Sliding door cable or motor failure

   • 28 complaints (12%)
   • median 30,000 mi at 3.8 yrs old (18 state mileage)
   • 3 mention a crash, fire or injury
   • filed 2015–2026

   Several owners report the automatic door cable snapping or rusting through, after which the door cannot be opened manually or with the buttons. Others had a dealer diagnose a failed door motor. Repairs were often described as expensive, and some owners left the door operating manually. Mostly reported between about 30,000 and 94,000 miles; one owner noted a rusty cable on a van kept mostly in a garage.

   Recall 16V858000

   What to check: Open and close each sliding door fully several times and listen for strained motor noise or binding. Have a mechanic inspect the door cables for rust or fraying.

   “The cable to my side power panel door snapped yesterday. It is hanging from the side of my car - what doesn't seen right is that the cable is rusty - it looks like it snapped because it is was exposed to moisture. The door is completely unusable - I cannot open it using the manual or power mode. My van is in my temperature controlled garage the majority of the time and there should be no reason that the cable is showing signs of rust other than a design flaw.”

   NHTSA complaint #11348896, filed 2020-08, 94,000 miles

   “Cable to open automatic door broke was told this is not covered in the latch system recall. Vehicle was stationary at time of cable break. Also back up camera doesn't work properly and touch screen raido/back up camera continue to reset itself when driving”

   Electrical system

   Instrument cluster and infotainment screen reset or go dark

   • 11 complaints (5%)
   • median 19,000 mi at 2.7 yrs old (7 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 2016–2026

   Owners describe the dash display or navigation screen freezing, resetting to defaults, or going dark while driving, with steering-wheel and screen buttons unresponsive during the reset. Some report the instrument panel dimming so much it is hard to read. Dealers sometimes could not reproduce the problem; when they did, they applied a software update or hard reset, and in some cases the problem came back. Reported from roughly 1,000 to 40,000 miles, during normal driving.

   What to check: During a test drive, watch whether the cluster or screen flickers or restarts, and check with the dealer whether any software updates were applied.

   “Steering wheel becomes difficult to turn making it hard to steer - almost have to force it to turn. Hard to duplicate - seems intermittent - instrument panel goes dim, almost dark. Random also”

   NHTSA complaint #11052032, filed 2017-12, 18,000 miles

   “Navigation system / screen restarts intermittently while driving under normal operating conditions. No buttons on steering wheel or on navigation system are operational during this period.”

   Electrical system

   Speedometer hard to read in daylight

   • 12 complaints (5%)
   • median 17,191 mi at 2.5 yrs old (10 state mileage)
   • filed 2015–2021

   Owners report the analog speedometer and tachometer are not illuminated unless the parking or headlights are on, and even then stay faint. With sunglasses on or in bright sun the gauges are described as difficult to read, and this model year has no separate digital speed display. Reported across low and moderate mileage, typically noticed in daylight driving.

   What to check: Sit in the van on a sunny day with the lights off and confirm you can read the speedometer comfortably; ask whether any gauge or cluster work has been done.

   “The dashboard speedometer and tachometer gauges cannot be illuminated without turning on parking or headlights. These gauges cannot be seen during the day when the dashboard is shadowed. Issue has been reported on Sienna chat boards and numerous Toyota service departments.”

   NHTSA complaint #11032970, filed 2017-10, 31,192 miles

   “There was no accident or incident. I'm trying to avoid a potential accident by being forced to see the gauges that are essentially invisible while driving. The standard tachometer and speedometer gauges in this car have dark faces. When driving on a sunny day with sunglasses on, they are almost impossible to see. This is a definite safety issue as one has to look very closely and longer than normal to be able to see one's speed. The optional se model has these instruments with white faces and would be much easier to see in bright conditions. …”

Buying note. Check the sliding doors thoroughly and confirm recall 16V858000 was completed, since door problems are the most common owner complaint. Also test the dash and screen electronics on a drive and look at tire wear before deciding.
