“Leaving the sonic drive in parking lot my vechile died as I was turning on the street. It showed that the gas tank had a 1/4 tank of gas but the tank was empty”

NHTSA complaint #11319249, filed 2020-03, 100,000 miles

“Toyota uses new green (environment friendly) wiring that is tasty to rodents and other pest- they are aware that it can attract animals to eat the wiring and electrical systems on their vehicles and refuse to cover the damages incurred on the warranty - they refer the customers to seek monetary aide from their insurance company - in my case it was $3000.00 in damages to my vehicle for a rat eating the wires /electrical system. My insurance paid for it - but how can I be assured it will not occur again. ?? Toyota needs to be responsible.”

NHTSA complaint #10644989, filed 2014-10, 37,000 miles

“I came home last night at about 9:30 pm and parked the car in the garage. This morning at 7:30 am I went into the garage and heard a buzzing sound coming from near the rear wheels of the car. My best guess was the fuel pump was still running (I had a different problem with a fuel pump not running when the ignition was turned on with a 2000 jaguar about a year ago). I turned the ignition on and off without cranking the engine, the buzzing continued. I started the 4RUNNER, ran it for about 20 seconds, and shut the engine off. Buzzing stopped.”

“This vehicle does not get anything close to the 22mpg highway miles per gallon as posted on the window sticker. The dealership tells me that the computer is faulty and does not calculate the mileage properly and that is the way they all are. But, I have all the receipts for every tank of gas purchased since new. This vehicle has only been getting 17.8 miles to the gallon on the highway on average. I've complained to the dealership twice but get the same answer. I can't depend on the on-board computer read out as to the fuel mileage, they tell me - it is inaccurate . …”

NHTSA complaint #10513483, filed 2013-05, 1,000 miles

“I was driving on the expressway, at about 70 to 75 miles. Suddenly the vehicle just slowed down to 40 miles per hour. I almost got hit from the back by a truck. But, then it suddenly picked back up. this has happened several times but the shop nor the dealer could tell me what was wrong. I finally took it to another shop and they said it was the fuel pump. So I start researching to see if there were recalls on the fuel pump and yes their are. But not for my vehicle year. They are for 2013 to 2020. What can I do about that? This started about 3 to 4 months ago.”
