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 2012 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.

  • 25,017 miles


The contact owns a 2012 Honda Accord. While driving approximately 60 mph, the brake pedal was depressed, but the engine revved and rpms increased rapidly. The engine seized for a moment. After applying the accelerator pedal, the vehicle resumed normal operation. The failure recurred on a separate occassion. The vehicle was taken to the dealer twice, but the mechanic was unable to duplicate or locate the failure. The manufacturer was not notified of the failure. The approximate failure mileage was 25,017.

Vtc actuator grinding noise - in the spring of 2015 I started to notice a grinding noise when the car was started in the morning. I took the car in to Honda of bowie (bowie, Maryland) on May 23, 2015, and they said it was the vtc actuator and that Honda had the concern under investigation, and that Honda would not cover the repair. They also said they would contact me with any additional details. It has been nearly year since I brought the car in, and Honda has not contacted me and the grinding noise now occurs not only every morning but now every time the car sits for a couple hours. I am very concerned that this problem is getting worse and I am worried about the long term reliability of this car and associated future repair costs associated with this issue.

Operating on the highway and vehicle had a loss of power. This loss of power happened when trying to merge into fast moving traffic on the interstate. The vehicle loss power as the merge began and caused vehicles operating from behind to drastically slow down or pull into left hand lane also, was unable to safely travel in the slow vehicle lane because of the loss of power. Evidently, dealership reported several cylinders had oil fowling on the spark plug. The engine was taken apart and cylinders 1,3,5 rings were replaced.

Engine coolant, thermostat, radiator and engine failed at a mere 37K miles. Honda refused to cover. It was in motion when it started smoking and shooting out fluid from under the hood. Had it towed to two Honda dealerships only to not have it covered.

I was slowing down and braking for a red traffic light. I had to apply a lot of pressure on the brakes as it felt like the car was going to accelerate. This is the second time that I had this particular problem. Both times, this acceleration attempt when I was braking, did not happen for the remainder of my drive. I did not notice the engine revving or see that the engine was overheated. I was driving on city street where the posted peed limit is 25 mph and I was driving withing the speed limit.

This is an intermittent recurring issue with the vehicle. When making a slow speed turn, typically accelerating from a traffic light or stop sign, the engine will not respond to the accelerator being depressed. This occurs if I have to lift off of the accelerator and reapply pressure, due to traffic slowing around turns or other driving conditions that necessitate lifting off of the gas pedal and then stepping on it the problem has not happened when going straight, only on turns. There have been times where this has proven to be unnerving and potentially dangerous as there were vehicles approaching and the brief hesitation caused what could have been an easy turn with no chance of an oncoming vehicle hitting my car to a situation with the potential for my vehicle being struck. When the first few hesitations occurred I was advised that it could be caused by the drive by wire technology. As I review some of the forms I see numerous instances where others have experienced this momentary non response when pressing on the accelerator. I also noticed that this is not just an Accord issue as other Honda model owners have experienced this same problem. At first this was an annoyance, but as stated it has become more of a safety concern.

I am experiencing the issue outlined in tsb 09-010, at cold start-up, the engine rattles loudly for about 2 seconds. I am in the process of trying to contact american Honda to see if I can get goodwill to get this repaired. It is unacceptable that this is such a widespread known issue yet Honda fails to issue a recall.

I was driving on a down hill road ( about 0.3 miles), and my transmission was exactly on "D". because it was a down hill road, I released my gas pedal. However, suddenly my engine made some acceleration sound, and on the meter, it showed that the engine speed was increasing from 2000rpm to 3000rpm. (please notice that I was not feeding the gas at that moment because I was driving on a down hill road ). I immediately step on the brake and the engine began to slow down. I need to drive on this road on a daily basis. This kind of incident had never happened previously.

While applying brakes, the engine revved up and car started to accelerate - I had to move transmission into "neutral" to stop vehicle. It was inspected the following day by a Honda dealer and they said that the car was functioning normally. It has happened 3 times since it was inspected by a 2nd dealer, the latest time was March 7th, 2015.

Vehicle does not accelerate, but hesitates 2-4 seconds from a stop or near stop, then suddenly surges to mid throttle forcing the driver to either brake suddenly or avoid hitting another vehicle. Happened 4 times in one year with my car.

Our 2012 4 door/V6 Honda Accord was involved in a crash. A mack truck hit our car from behind at an estimated speed of 50. We hit the car in front of us at an estimated speed of 20. The vehicle was considered totaled with an estimate of $22000-$25000 in damages. The front airbags never deployed. In my research, 2012 Honda's had a recall regarding side airbags not deploying ( I am concerned there might be an issue with the front airbags as well. I reported the issue to american Honda as a safety concerns for other Honda owners. Honda documented all the information regarding the crash then instructed me to have a private individual inspect vehicle to determine if there was a malfunction with the airbags. If so, then they want us to submit the issue in writing.

I was on the street, approaching a red light. All of a sudden the engine started to speed up. The car did not jump forward. I immediately pressed on the brake, put the car into park, and shut the engine. Luckily there were no cars in back of me. I started the car again. Everything seemed normal. Two days ago, on March 22, I was parking the car on the street between two other cars. I was in either D or R, when the vehicle started to race again. I followed the same procedure as before, and shut the engine. The first time this happened, I took the car to a Honda dealer. It was claimed they drove the car and everything seemed fine. Several weeks ago as normal maintenance, I had the transmission fluid changed at the Honda dealer. This seems to be a very dangerous situation. Please investigate.

When cruising on the highway, the steering wheel develops a vibration. Also, when the car is idle, it vibrates almost like a cylinder is missing a spark. Only have 34000 miles on this car and its giving me these issues that they say "can't be fixed".

2012 Honda Accord. Consumer writes in regards to engine misfire that may disable vehicle. The consumer stated the vehicle was still under warranty. Supposedly, a federal court authorized a notice regarding the engine misfire problem. The dealer informed the consumer, even though his VIN was included, there was nothing they could do, until he experienced a failure.

Accord 4-cyl

That was on Monday 12/31/2012 while traffic in freeway was very clear. I set cruise control at 60 mile/hour but suddenly the car kept increasing faster more than 75 miles. I was panic and kept stepping brake to reduce speed. About one minute, the car was reduced at speed of 50 miles/hour. I tested it without cruise control. I drove steadily about 60 mile/hour about 10 minutes that the car started accelerated by itself again and hit 75 miles/hour. I kept stepping brake steadily to reduce speed until it kicking into 50 mile/hr. This car is definitely defective car with numerous issues. Its defrost system does not function at all that almost killed me on September 2012. Again I brought it to dealer on 01/02/2013 for accelerated issue and defrost system but Honda power dealer still could not detect it. I filed complaint with ftc and district attorney/prosecute unit to request to investigate about this issue. I contacted to Honda motor to request it to take this car back and terminate my lease but Honda motor refused my request because Honda motor used test results from power Honda dealer and Honda world dealer as Honda motor 's decision found that there were not any defective with defrost system and accelerate found. Honda motor made this car and failed to detect its problems that is no matter it can detect this car problem or not that Honda has to hold accountability to lease it to me.
