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. Notes: The 2010 Honda Accord has a solid reputation (so far), with one very significant flaw: uncomfortable seats.

Owners have consistently reported uncomfortable seats with the entire 8th generation (2008-2012) of Honda Accords. Complaints range from back pain to leg circulation problems due to bad lumbar support, cushioning, & seat angle. Complaints aren't limited to only a certain body type -- the seat comfort problems are from a wide spectrum of owner height & weight.

The common theme we hear is "we never noticed this during the test drive." Unfortunately for unwary buyers, the seat pain is noticeable after 15-20 minutes.

My Accord oil light illuminated on and off when there was 40% oil remaining, and therefore, I took my vehicle into fletcher jones Honda, which is where I regularly go for routine maintenance service. Then I received horrific news concerning the life of my vehicle, which is in need of a brand new 3.5-liter vtec V6 engine, which will costs $12,372.87. This was especially alarming news because, my vehicle is only six years old and I've only have Honda to service it. Also, it was recommended that the following maintenance is performed: Timing belt replacement $565.39; clutch assembly $2,019.86; spark plugs replacement $209.52 and syn power (EFI service/fuel injection cleaning service $159.95, which brings my out of pocket costs to $15,327.59.

When driving on the freeway on my way to work the check engine light came on. After exiting I checked for error codes (as I always carry the P-code reader with me). The code stated that cylinder 3 was misfiring. I double checked all spark plugs to make sure the connections were okay. The engine light continued to come on, with a rough idle, and engine codes started to be more spontaneous as it stated random misfires/multiple cylinder misfires. I took my car to Honda and was told that I likely need to replace the ignition coil, so I did that and still experienced the same problem. I then took it to a shop where they also suspected bad ignition coils. They then did a valve adjustment and was positive that would fix the problem. After performing that job, the car continued with the same rough idle but only populated the error code stating cylinder 3 is misfiring. They took out the spark plug and ignition coil on cylinder 3 and discovered a cracked intake valve. I've spoken to at least 10 shops, 2 Honda service dealerships, and 2 personal mechanic friends that all state that a broken intake valve at 107K is very unusual and likely a result of poor design. I have read about the class action lawsuit for all V6 Honda Accord between 2008-2012. Unfortunately the 2010 V6 6 mt is one of the few models left out of that law suit. I have already had a shop start on the repairs as I have no choice but to have them done asap. I figure an unlikely event like this is due to poor engine design since I have thoroughly kept up with all scheduled maintenance (spark plugs, timing belt, water pump, oil change, etc..). I feel that Honda should be responsible for this 2000$ dollar repair.

The past two times I have brought the car in for an oil change I have been told that the oil level is below the dipstick. Both times I have brought the car in for an oil change with 20% oil life showing. Shifting from 2nd to 3rd sometimes gets "blocked". that is the only way I can describe it, you go to shift and cant get into gear, either have to go back to 2nd or back to neutral and then back in. The "double pump shift" usually works. I have also had a problem with the speaker deck rattling which I had supposedly fixed under warranty but only to have the same problem.

The contact owns a 2010 Honda Accord. The contact stated that a rattling noise emerged from the transmission and made a loud sound. There were no warning indicators illuminated. The dealer stated that a secondary shaft bearing fractured. The vehicle was taken to a transmission specialist and the diagnosis was the same. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 100,370.

Purchased vehicle 5/8/2014. Driving home and I called my husband and stated that the car sounded like crap--wasn't shifting correctly and just had a horrible sound coming from engine. He stated we will check oil and transmission fluid when you get home. To find no oil or transmission on either. We immediately contacted dealer we purchased from and we had it towed there for attention. Car dealer changed oil(which wasn't much) and transmission fluid were "fine". passing the buck! we continued to keep an eye on it to find we are putting quarts of oil in it. It has had 3 oil changes in less than 6 months and not due to mileage---due to each place we took it to-dealer-changed oil, jiffy lube-changed oil-Honda-changed oil and started "oil consumption" test. I have checked oil in my cars, since I was 16 years old. Honda stating "it's normal"--it's not normal to have to keep adding oil to your car between one oil change to another, due to mileage only. You can visually see oil everywhere on the engine block and laying on other components of the engine. Fix the car!!!!!!

Excessive oil consumption. I am putting 1-2 quarts oil every 3000 miles, even though the oil life indicates 80% or better. I bought this car new and just noticed this about 9 months ago. The oil is not leaking, it is just gone. Also when I start the car first thing in the morning or when is cold, the top of the engine makes a rattling noise. There is also a loud pronounced noise that sounds like it is either the engine or the transmission, something doesn't sound right. I am taking it to the dealer to have it checked out.

When starting the car at a cold start, you hear a loud grinding noise sounds for 2 or 5 seconds. There is a tsb 09-010 regarding a vtc actuator that drains of oil and is not properly lubed when starting the engine cold, causing the grinding noise until oil reaches the part again. Grinding noises in an engine are bad, and could lead to catastrophic engine failure should the abrasive metallic parts (due to grinding when there is no oil in the actuator) becoming lodged. This engine failure could happen at any time, possibly in a highway lane. While my car engine has not yet seized, there are online reports of this happening. Currently, Honda will only fix this issue under warranty. They also give the car owner a really hard time proving the issue, requiring the car be left at a dealership overnight to replicate the problem. A loaner vehicle is at your expense. If the car is not under warranty, this expensive repair bill is at your expense. If your car is under warranty and they are not able to replicate the noise, both the loaner car and diagnostic fee are at your expense. This greatly reduces the number of people willing and able to have this important safety issue fixed. Running engine components without oil should be a recall. It is clearly a safety issue that can cause other problems with your engine. If the engine stalls unexpectedly, it could lead to death.

Transmission jumps. Hesitates and stalls somewhat frequently, a lot more than to be expected of a car only 2 years old. More so at the lower gears when accelerating. RPM is not consistent with throttle input. Unfortunately, it does not trigger the check engine light, so Honda does not see an issue, but something is off with the drivable.

At 20,000 miles the vehicle had a failed wheel bearing (noise/vibration), passenger-side front. Driver-side front wheel bearing failed at 34,000 miles. Dealer replaced the hub/bearing assemblies under warranty. This is a defect, as the bearings should not fail at such a low mileage. How long will the replacement bearings last ?

The car had only 4100 mi. And consumed a complete fill dry. Took it to local dealership and was told that this is normal at times for the car to do this one time. Car was also shutting the cylinders down at app.30 mph not the 55 mph it was designed to do to save mileage. It was returned to us and 3 days later started doing it again. Returned to dealer and was told it had the wrong plugs in it.changed the plugs and returned to us. Drove the car appp. 90 mi. And started it again. The service mgr. Told us that this was happening to more than my Accord. This time they called and told me that the rocker arm pin in cyl. No.2 was undersized and was sticking closed, causing a miss. But not sure if this would fix the problem or not. All the while they were communicating with engr. From Honda. They have my car for a week and it is a lease.they are talking of changing a head or maybe even the block. Purchasing a $30000 auto and having only 4900 mi. Is not acceptable. I would like another Honda in it's place and I would be completely satisfied. Had the rocker arm stuck open the piston would have exploded and could cause great bodily harm to myself and anyone around me at the time. This is a dangerous situation occurring here and could really involve a lot of innocent people if it continues.
