Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2009 Acura TSX Owner Comments

problem #7

TSX 4-cyl

  • 10,000 miles


Purchased vehicle new. After approximately 3 months of ownership complained that odometer was not correct. Further issues included replacement of wheel bearings twice and extreme oil consumption. Each time is was brought to the dealer the problems were ignored, determined to unduplicatible or I was told nothing was wrong. Currently I see that there are tsbs relating to the steering/bearing issue and the oil consumption issue. I repeatedly tried to no avail to have these problems fixed with the dealership and filed two complaints with Acura corporate customer relations and received no assistance.

I purchased a new 2009 Acura Tsx. Since I purchased the car, I have experienced a pinging in the engine. I took the vehicle to the dealer and had the mechanic drive with me to validate the problem. He acknowledged the pinging noise. The dealer advised me that they contacted Honda who gave their standard response of "it is a normal engine characteristic". ironically enough the euro model of the Honda has the identical engine. Honda has acknowledged the problem with the vehicle there but continues to deny there is a problem here in the us. I paid $30,000 for a car that has a serious engine condition that will most likely result in serious engine damage over time. Ideally I would like to return the vehicle but Honda denying there is a problem is the first hurdle. Please advise me of my options.

Engine making pinging sound around 1800-2500 RPM give or take while under any kind of acceleration. Vehicle is a manual transmission. It doesn't matter whether its warm or cold. Can be in any gear. Problem occurs most of the time. Vehicle is 5 months old.

Noise coming from 2009 Acura tax rearend driverside. Piping noise can be heard when stopping and accelerating. There is a frame flaw. I am told Acura has a design flaw. They have to fuse two metal pieces to get the noise to quit and the dealer had to order a special tool from torance ca. What else is wrong with this horrible Honda product. Oh yeah and the engine pings a lot. What are we to do?

No incidents yet. But--the engine of my brand new 2009tsx "pings"--produces "metallic noise" every time I accelerate. I have called a local dealer in brooklyn, NY and they assured me that it was a norm...

Upon acceleration, engine makes a rattling noise. I have reported this to crown Acura in richmond, va, where they have inspected the vehicle and say this is considered a "normal" sound. The sound is unnatural; I am concerned that this sound will eventually lead to a larger problem and possible engine failure. I have reviewed internet discussion boards and others report this problem as well.

This is a 2009 Acura Tsx. While driving there is a rattle-type sound that comes from the engine. Took the car to two Acura dealers and both acknowledged the sound, but declared it a "characteristic" of the car. Hundreds, if not thousands of other '09 Tsx owners are experiencing this same noise (there are several blogs all over the internet) and we are concerned that it might cause some sort of serious damage while we are driving the car.
