“The engine failed while entering the highway. All power was lost and vehicle had to be towed to the local Toyota dealer. I was informed today that in order to analyze the problem the engine needs to be removed at $140 per hour approx. 20 hrs of labor. I have given them permission to do this so I can receive a quote as to how much to repair. This Sienna was just in for 125,000 mile service with no known issues. I do not have any type of documentation as of today june 4,2018.”
NHTSA complaint #11099856, filed 2018-06, 125,000 miles“In motion, when I let up off the accelerator to assess traffic, such as at the top of an on-ramp or other merging situation, then I decide it is safe to merge, and I press the accelerator, the vehicle stalls briefly before catching and accelerating. The engine doesn't sputter or cut off, the vehicle just sits still as though it isn't getting gasoline. I've had a few close calls when attempting to accelerate and merge into traffic. This isn't a gear down-shift/up shift type thing...just a stall. It's not every time I slow down to coast, then decide to accelerate, but sporadically. …”
NHTSA complaint #11081494, filed 2018-03, 45,000 miles“About 20 minutes away from home we heard some growling and ticking noise from the engine. No instrument warning lights came on. As we pulled into our steep driveway, the oil pressure light started to blink. We shut the engine. Upon inspection, the oil dipstick appeared dry. I added about 4 qts of oil, and started the engine. It sounded normal, and no warning light was displayed. I brought the car to a level area and checked oil again. I added another quart - oil was between the marks on the dipstick. I noticed light dripping from the front area of the engine, near the oil cooler. …”
NHTSA complaint #10861960, filed 2016-04, 96,000 miles“Toyota Sienna 2010 minivan engine stalls while driving. When driving on highway or on city roads, engine stalls and looses engine power for a few seconds (seemingly happens when shifting gears) when accelerated or decelerated. The engine basically stalls during driving and may lead to sudden vehicle slowness in middle of traffic. The suspected problem advised by Toyota is with transmission and the original cost estimate was $5100 to fix that. …”
