The problem is not specific to this car. The tire speed rating system in use today is long overdue for upgrading. Problem 1 is the confusion that exists between Y and (Y). Online tire dealers often blur the two categories. Problem 2 is the actual speed rating of (Y) -- it is unknown but higher than 186. Problem 3 is that tires in the upper ranges are not separated. If you buy tires for a 2004 Ford GT, they must be good for up to 215 mph, but 270 mph is not necessary. There are many tires that are good for 215 but not 270 mph. The current system does not tell consumers which tire is safe! I propose a new metric-based system. The following speed ratings would assigned to each tire: Speed rating 15 (150 km/H) 20 (200 km/H) 25 (250 km/H) 30 (300 km/H) 35 (350 km/H) 40 (400 km/H) 45 (450 km/H) 50 (500 km/H)

I was driving home on a 2 lane city street a few weeks ago when I heard a loud crash/explosion of some kind on what seemed to be the top of my car, when I had gotten home I saw the sunroof had completely smashed as if something had fallen on top of it, but I and the guy who replaced the sunroof found no rocks or any point of impact on the sunroof, so it had appeared to crack spontaneously. We had been having icy weather the week prior but it had been cold enough for a while that a sudden temperature change couldn't have been what caused it. No glass fell into the vehicle because the inner lining of the roof had been pulled shut, but it cost $700 to replace it and we had to drive to omaha, 60 miles away from where I am, to get it replaced.

On the morning of 12/16/2016, while in the parking garage where my wife works, she stopped to back into a parking spot and the car suddenly accelerated forward and would not respond to vigorous braking nor the emergency brake. The car hit a concrete wall, the air bag deployed, and she was injured (numerous fractures to date). We have seen the words 'brake override' and 'sudden unintended acceleration' in cases against Toyota. There were no floor mats in the car. We bought this car in the first week of Oct 2016, so it was only approx 75 days in our possession. The dealership could never get us in contact with the previous owner (about unrelated questions) and never mentioned any possible issue with the car. They gave me a carfax, but there was no mention of the sua issue. We feel Toyota or someone should be responsible for this happening. Not only is there physical damage to the person, but also mental damage about driving any car. We believe the electronics are to blame for this happening. What are our options? we cannot find anyone to take the case. Please advise, thanks.

I am greatly concerned about the fact that how Toyota is handling manufacturing defects could lead to the injuries or deaths of its customers. We received information from Toyota saying that the onboard computer for the car was defective and needed to be replaced. However, the company did nothing for months despite repeated phone calls. Toyota representatives on the phone initially provided no help in getting the problem resolved. We finally got permission to bring the car to a dealer for repair, which also had the engine light on (there can be many reasons for this, but they should be easily identified. I had to wait several hours because the initial replacement was also defective (I believe the date was 6/8/11). As I drove away from the dealership, which was now closed, the engine light came back on. We had to bring back the car, and were told that the 02 sensor was defective. I have read on the internet (although I don't know the accuracy of this) that Toyota has been putting defective O2 sensors in cars that don't last as long as they should (ours only has 42K). We then had to pay an independent mechanic with a much higher customer service rating than Toyota dealers have to find out what is actually wrong with the car. The problem was confused by the fact that the onboard computer was not consistent or accurate. For days the engine light was on, for days it was off. These mechanics said that the Toyota dealer made an error and did not clear the computer's history so any future problem could be easily identified. So they cleared the history and we had to bring the car back in a few days. They then replaced the apparently defective O2 sensor. We hope this is over but don't have great confidence. There have been many problems reported with the Matrix. Edmunds.com reports that "a periodic problem with this vehicle is failure of the powertrain control."
