The drivers side "sinking seat" problem started when I first bought the car in 2009. At that time, the local Toyota dealer was coughlin Toyota in newark Ohio 43055. Coughlin told me they had no fix for the problem and never heard of it before. The drivers seat can be manually adjusted up or down by hand. There are 20+ positions up or down. Short people need the seat position to be all the way up in order to see over the dash board and hood for safe visibility and vision when driving. Tall people would want the seat position to be all the way down. I am short, 5' 6" tall. I need the seat to be all the way up for safe vision over the dash board and hood. The "sinking seat" problem occurs when the seat gradually goes down several positions on it's own. I believe this is a design defect by Toyota, not a user caused condition. This problem covers several years of Toyota production. It has been reported by others on google. I have local friends that have the same problem with their Corollas. Today, 9-5-2013, I again reported this problem by on line email to Toyota corporate for a solution. Here is an exact copy of my report to Toyota: "my 2009 Corolla has the wide spread and chronic safety problem of "sinking seat syndrome" with the driver's seat. When will Toyota have a fix for this chronic safety problem? my local dealer, coughlin Toyota, has no knowledge of the problem or a solution. This problem is very common on the internet (google). Some of my local friends have the same problem with their Corollas. I normally have all my Corolla maintenance done at the local Ford dealership for fast service and quality work. Unfortunately, Ford is not familiar with this specific design and safety problem. Can you help with a fix? if you just refer me back to coughlin Toyota for help, I am in big trouble"

My head restraint in my car pushes my head down so I can barely see out the windshield to drive. Which government idiot came up with this brilliant idea of redesigning the head restraints so they stick out so far. Does he even drive a car? the government has never done anything right, and this is just another example. Stop figuring out your excessive pension plans and all the vacation time you have, get off your buts and fix the problem you caused. I think everyone should send their chiropractic bills to you clowns.

Toyota Corolla 2009. I have owned this car for over one year, and I must say that the design of the front headrests is flawed. Very uncomfortable and not ergonomic at all. The headrests angle forward (and are not adjustable), pushing the driver's head/neck 45degrees forward. There is no reason for this, and it gives me neck strain, and puts upper chest in closed position, promoting poor posture, breathing and view of the road. The 'active restraint' feature is supposed to push the headrests even further forward in case of a collision..I suspect a neck injury would occur in case of collision (head snapping forward past 45degrees).

I purchased a brand new Toyota Corolla 2009. Since the date the car was taken from the dealer, the passenger seat keeps sinking lower without touching anything. This causes the mirrors to get out of Focus since the position of the driver's seat changes, causing a hazard when emergent lane changing is required. I have taken the car to the dealer over six times. They deny there is a problem and have not taken care of the problem.
