When I am about to go downhill and take an exit at 40 mph after driving at constant speed of 65 mph for some time I see this problem. RPM is suddenly spiking up from 1500 to 2500 and stays there for at least 5 seconds. Hit brakes or gas does not bring it down. Good thing is the speed of the vehicle is not going up. That's the good sign but who knows what happens. I thought this was the problem with econ drive but I turned it off about 3 months now and still having the same issue.

I am a fuel efficient driver, drive with the econ button on mos of the time. I drive 150 miles 5 times a week. Every time I am going downhill and I push the brakes to slow down, the RPM's go up. I also tried driving without the econ to see if it would change and the same thing happened. You would think by hitting the brakes a little harder would do the trick to decrease speed, but it doesn't. as you start holding the breaks for a long time, then the rps would decrease. I have looked online and many people are saying the same thing. Example: www.civicforums.com/forums/210-engine/350659-2012-Honda-Civic-ex-engine-braking-econ-button.html.

I've had my 2012 Civic for a little over a year now and have been experiencing the following issue right away: While maintaining speed at 1500 rpms, they suddenly jump to 2500 rpms, pause at the higher RPM for a few seconds and then come back down. I cannot recreate it at will, it happens while driving on flat and straight roads (as this is my usual drive to work and home), applying the break does not bring the rpms back down either. I have driven a decent amount of cars in my lifetime including a 2003 Civic in the same trim as my current Civic and none have acted this way. I realize a lot has changed since that '03 Civic model, but no car should act like it has a mind of its own, which is exactly how it feels every time this occurs and leaves me with a very unsettling feeling while driving it.

Hello good morning, yesterday I was getting home and I was pressing the brake pedal and when I release the pedal my car was getting into my parking slot at a speed of 5 mph, suddenly lights started blinking and the card accelerated it self hitting a rock or something in front of my house. I have a little injured in my hand but nothing I think serious.

When the car is parked in a downward slope facing down, and you engage the reverse gear, the car rolls forward. This is especially difficult to control if you are parked in a tight spot and you will roll and hit the car in front of you. We reported this to Honda corporation and they said that this is normal behavior. I do not agree, since my other car (different make/model) does not perform the same.

Rev. Suddenly goes about 3500prm and stay there for a while when I drive downhill. At that moment when you step on the gas pedal the car will not accelerate like normal. Sometime there are car behind you and this is very dangerous because your car can not go as far as the car behind you. Please test the 2012 Honda Civic, this car have problem.

At approximately 7:45 a.M. I arrived at work and turned left into parking space to park. I was driving a 2012 Honda Civic, which was less than one month old. The car lunged forward when I took my foot off of the accelerator, jumped the parking bumper and struck a concrete wall. The driver's air bag deployed and the front bumper was scraped and knocked out of place. American Honda has inspected the car and claims that nothing is wrong with it but refuses to release its report to me.

While trying to slow on a highway curve by pushing the brake, I was unable to do so. The car continued to speed up as I pushed the brake. I pulled my foot back and reapplied the brake with no affect, the car was continuing to speed up. I do not know if I removed my foot from the brake or just slammed the brake. The brake took hold the car jerked. I removed my foot from the brake and continued to drive. For a brief period I did not have control of the car.. this was not my first unexplained acceleration incident. The other 2 times I was slowing into a redlight by just removing my foot from the gas. The car slowed as I expected it to do then it just began to slowly speed up. I was not going down hill. The brakes worked and I was able to stop. The dealership was unable to duplicated those incidents.

I was trying to back into a parking space with my 8 month old, 2012 Honda Civic. As I took my foot off the gas pedal to put the car into reverse and before I could step on the brake, the car surged forward at a tremendous rate of speed, jumped a curb and went straight into a brick building. The car bounced backwards onto the parking lot and I was able to step on the brake and regain control. This happened in a matter of a split second with no time to jam the brake on as the car lurched forward. Even though the car jolted tremendously, the air bag did not go off, but a service light came on the dash board indicating "check airbag system."

My Honda Civic ex-L 2012 failed to accelerate from a stopped or idling position. This has happened approximately five times in the three weeks I have owned the vehicle (current odometer reading as of this writing is 650 miles). I have noticed it most often when attempting to accelerate from a stopped or idling position to make a left hand turn. However the left hand turn may be more noticeable as I am turning into oncoming traffic/crossing lanes and the failure to accelerate, and the collision risk the failure imposes, are most alarming. I have also noticed a lack of gas pedal 'responsiveness' when stopped or idling and attempting to roll forward slightly as one would attempt to do in a line of vehicles. Of note, my husband has a Honda Civic LX 2012 which he has owned for five months. The same failure to accelerate from a stopped or idling position has occurred while I was driving his vehicle approximately three times. He has not noticed it, but almost all of his mileage is highway driving. I intend to bring my vehicle to the dealer this week to have this potential safety hazard investigated.

While driving on the highway at 50mph at 2500rpm all of a sudden my RPM went to 4000 without me accelerating more I got scared and tried to slowly slow down the vehicle but RPM remained at 4000. And it remained like that till I stopped the vehicle and restarted it.

I got into a accident last Monday, Feb. 13, 2012, like around 8 or 9 in the morning. I was making a right turn when my car went out of control even though I was already stepping on the brakes and I was trying to turn the steering wheel to the left but the car just kept going to the right until I hit the pole sign that says "no parking at all times" (something like that). The metal pole that I hit broke and almost 1/4 of that metal pole that was stuck to the ground scraped the bottom of part of my car and the bottom covering fell off and it cost $4,000 to repair and now I have to pay $500 for my deductible which is not even my fault why my car did that. It wasn't the first time my car did that. It did something weird twice last year before I got into this accident last week. First was last year, a month or two after I got my car when I was driving on the freeway when I tried stepping on the breaks and instead of my car slowing down, it suddenly accelerated. Thank goodness there's no car in front of me. Then the second time was I think around November or December of last year when my friend was test driving the car to see if she wants to buy the same thing. We were together in the car and she was driving when she stopped stepping on the gas and brakes and the car just accelerated by itself. She was surprised that it that but we both figured that any car is just like that and since we both don't know anything about cars we thought it was normal for my car to accelerate on its own until I got into this accident, the police told me that it is not normal for my car to do that specially when I'm already stepping on the brakes. :(

The contact owns a 2012 Honda Civic. The contact stated that while reversing into a residential garage, the vehicle accelerated forward as the brake was disengaged. On a different occasion, while driving uphill and releasing the brakes, the vehicle surged backward. In order to stop the vehicle from rolling backward, the contact had to continuously depress the accelerator pedal. The vehicle was taken to an authorized dealer, who stated that the failure was normal. The manufacturer was made aware of the failure, but offered no assistance. The vehicle was not repaired. The failure mileage was 600 and the current mileage was 1,200. Updated 09/21/11 the consumer stated she parked the vehicle on a downhill slope. As she started the vehicle, shifted into reverse, released the foot brake, and before she pressed the accelerator pedal to back out of the driveway, the vehicle rolled forward almost hitting a door.
