2002 Toyota Sienna Problems

What owners report

Owners of the 2002 Sienna most often report problems with the power sliding doors, which stick, jam, fail to latch, or stop working by cable or motor, sometimes at low mileage. Brake noise and, in a smaller number of cases, fading or soft braking in cold weather are also common, along with door locks that cycle on their own. Body and door-related hardware reports are the largest single group, and many complaints come in with the van well past 70,000 miles.

1. 1
   Body and structure

   Power sliding doors jam or stop working

   • 49 complaints (27%)
   • median 73,316 mi at 7.0 yrs old (35 state mileage)
   • 1 mention a crash, fire or injury
   • owner-quoted repair $1,000 (median of 5 quotes)
   • filed 2002–2016

   Complaints describe power sliding doors that intermittently fail to open or close, get stuck partway, or stop responding to either the inside button or the remote. Owners report cables that snapped, motors that failed, and doors that had to be forced closed by hand, with repairs sometimes repeated several times over the years. Several say the dealer could not reproduce the problem while the van was in the shop, and some were told a cable or motor replacement was needed, with estimates ranging widely. Others describe the door popping open or refusing to latch, and one owner reports the door jamming open while the vehicle was moving. Reported across a wide mileage range, from under 20,000 miles to well past 200,000, with many cases clustered around 70,000 to 100,000 miles.

   What to check: Operate both sliding doors several times, using the inside button, the remote, and the outside handle, and listen for cable or motor noise. Ask whether the door cables or motor have been replaced and whether the repair held.

   2 excerpts from owner complaints in NHTSA records

   “When I attempted to open driver side sliding door it would not open electrically or manually. After several failed attempts to open I cut the cable and was able to then open the door. At this point in time both sliding doors will not open electronically but will open manually.”

   NHTSA complaint #10704379, filed 2015-04, 240,000 miles

   “Power door failing to open and close properly. This has been an issue since we purchased the van in 2004. The doors would some times not open under power or would not close under power. We had to manually close/open the door. The passenger side door now will not close under power. When the problem was intermittent, we took the van to the dealer and they said there was no problem. Doing some research on the internet the repair runs in the $1500-$1800 range.”

   Latches, locks and linkages

   Door lock buttons and latch hardware fail

   • 31 complaints (17%)
   • median 75,000 mi at 7.0 yrs old (25 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2004–2015

   Owners report door buttons and handles that stick or break, leaving a door that cannot be opened from the inside or, in some cases, from either side. Some say the rear liftgate latch or its plastic link broke, so the gate would not open, and complaints mention that these repairs often came back after being fixed once. One recurring theme is the automatic lock system cycling on its own while parked or driving. Mostly reported between roughly 10,000 and 100,000 miles, with several cases recurring within months of a prior repair.

   What to check: Test every door handle and lock from both inside and outside, including the liftgate, and lock the van to see whether the locks cycle on their own. Ask whether any latch or handle assemblies have been replaced.

   “Every door handle on the vehicle has broken from the inside and outside. Almost every Toyota Sienna I see on the road had atleast one of there handles broken off. I really think Toyota should have a recall on this. The door has actually swung open while I was driving because I could not tell if it was closed proper. It did not result in an accident or more damage but could very easily have.”

   NHTSA complaint #10510192, filed 2013-04, 85,000 miles

   “The button on the sliding doors sticks when I try to open it from the inside, and it causes the door to be either unopenable or uncloseable, depending on what position it was in when the button got stuck. I had it repaired once , but it stuck again. The dealer is claiming they can't fix it because it did not happen when they had the car there at the dealership. This is a very serious safety concern - we had to crawl out the back because we could not open the door! …”

   Brakes

   Brake squeal and soft or fading pedal

   • 21 complaints (12%)
   • median 43,003 mi at 5.5 yrs old (14 state mileage)
   • 2 mention a crash, fire or injury
   • filed 2003–2019

   Complaints describe squealing or groaning at low-speed stops that persisted after pad, rotor, and drum work, with owners saying the dealer told them the noise was normal or not a safety issue. A smaller group reports the brake pedal going soft or feeling like assist was lost, sometimes in very cold weather after the van had been parked outside, or the ABS engaging on dry pavement during ordinary stops. Some also note the brake warning light coming on alongside other warnings. Noise reports appear from about 15,000 to 85,000 miles; the cold-weather pedal complaints are described in sub-freezing conditions.

   4 related service bulletins

   What to check: Drive and brake from low and highway speeds with the windows down, listen for squeal or grinding, and check pedal feel. On a cold start, test braking before pulling out; ask for service records on pads, rotors, and any ABS sensor or hub work.

   “Began having indicator lights on dashboard of my vehicle (Toyota Sienna 2002) come on for no apparent reason; specifically, the csv and brake lights concurrently. It seemed to occur more when temperature was cold outside. Initially thought it was a faulty sensor, but when the intermittent nature of fault became more frequent, was concerned could be a serious brake problem. I took to dealer; diagnosis was a 'faulty sensor' on the wheel's sensor/hub assembly . …”

   NHTSA complaint #10172370, filed 2006-11, 31,024 miles

   “I have taken my 2002 Sienna to the dealership (last winter) because the brakes have failed in very cold weather. The failure has happened three times, most recently this past sunday morning. The first two times the vehicle had been parked outside in below zero temps for a few hours. I backed out of the driveway (no problem braking in reverse)...all was well. However as I drove toward the stop sign it was as though the power was all gone from the braking system. …”

   Engine cooling

   Engine oil sludge and knocking

   • 10 complaints (6%)
   • median 37,500 mi at 2.8 yrs old (8 state mileage, few)
   • filed 2002–2010

   Owners describe gummy or sludged oil found at oil-change time and, in some cases, white smoke from the exhaust or a heavy knocking under acceleration. Dealer responses varied: some asked for oil-change receipts before considering engine work, others suggested a higher fuel grade or more highway driving. A related set of complaints covers rough or stalling idle traced to the idle control valve. Mostly reported in the 20,000 to 80,000 mile range, with several owners saying the van had been maintained on schedule.

   What to check: Check the oil on the dipstick for a gummy or milky look or a fuel smell, and look at the underside of the oil filler cap. Ask for oil-change records, and listen for a knock on a cold start and under acceleration.

   “My 2002 Sienna was diagnosed with oil sludge at 73,000 miles. Dealer says it cannot replace engine at their cost without receipts to prove oil changes. Since we did the changes ourselves we have no receipts.”

   NHTSA complaint #10148325, filed 2006-01, 73,000 miles

   “My 2002 Sienna has 26,000 miles on it and has a loud engine knocking when accelerating at certain speeds. It has been doing it for about the last 6000 miles. At 20,000 miles, scott clarkes Toyota in charlotte told me to use a better grade gasoline, with no results. At 24,000 miles, they told me I have spark knock and need to drive the car at higher speeds more often. (I drive mostly in the city). Reading the other complaints about sludge, I think this is related, since they told me my oil was sludgey too. …”

   Transmission and drivetrain

   Gear shifter breaks or moves out of Park

   • 7 complaints (4%)
   • median 79,000 mi at 8.8 yrs old (6 state mileage, few)
   • filed 2004–2014

   Complaints describe the gear shift lever breaking or the bracket it mounts to cracking, sometimes with little force applied, leaving the van stuck in gear or in reverse. One owner reports the shifter could be moved out of Park with the key removed, and another that the shifter broke while shifting into Drive. Dealers reportedly replaced the shifter assembly, and owners say the repairs were not covered. Reported between roughly 60,000 and 80,000 miles, typically during routine shifting at low speed or from Park.

   What to check: With the van running, shift through every gear and feel for slack or crunch, and check that the lever will not come out of Park with the key removed. Ask whether the shifter assembly has been replaced.

   “My wife was backing out of a parking space on a slight incline. When she stopped and tried to put the car into drive, the gearshift broke. We had the van towed to the Toyota dealer and they determined that the metal parts into which the gear shaft inserts had broken clean in half. Neither the customer service rep nor the mechanic had ever seen that happen before they claimed. Nevertheless, Toyota did not deem this to be a defect and we had to pay close to $800 to have it fixed. …”

   NHTSA complaint #10264978, filed 2009-04, 65,692 miles

   “I hope you will be able to help me out. My Sienna has 61022 mileages on it and we baby this car to the 't'. On february 11, 2008, I had just started the vehicle and was about to change from 'p' to 'd' when the gear shift lever broke. No force was used and we always pull back the shifter and change gears with minimal force. I had the vehicle towed to the dealer and the technician showed me where the aluminum brackets broke in three places. I was in shock that the design and material was not made engineered to last. …”

Buying note. Check the sliding doors, locks, and shifter carefully on a test drive, since those repairs can be frequent and costly, and get service records for brakes and oil changes. A pre-purchase inspection that includes the door mechanisms and a cold-start brake and engine check is worthwhile on a van of this age.
