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.

The contact owns a 2004 Honda Civic hybrid. The contact stated while driving approximately 40 mph, the vehicle shifted gears abnormally. The contact also stated after the accelerator pedal was depressed, the vehicle would not accelerate. The failure recurred multiple times. In addition, the vehicle became involved in a crash and the air bags failed to deploy. The contact received a voluntary recall from the manufacturer regarding the air bag warning light and was repaired however, the failure recurred after the remedy was completed. The vehicle was taken to the dealer diagnostic testing and they informed the contact that it could be an engine malfunction that had caused the acceleration failure and the air bag switch had caused the air bag warning light to become illuminated. The vehicle was not repaired. The manufacturer was notified and the approximate failure mileage was 25,000.

My car suddenly made a loud noise when making a stop on a busy intersection. I could manage to drive it to a safe spot before the car failed completely.the regular maintenance had been done in my car but I didn't know about the transmissions failures of the Honda hybrids until now. This is very dangerous.

The transmission is "failing" according to the dealer. It could fail this week, or next month. Even though there are only 126,000 miles on it, and I have done all the required timely maintenance on the car since I bought it brand new, the dealer said this just "happens" sometimes to these cars. In searching for information I have found several forums with other Honda Civic hybrid owners discussing the failing transmission problem and the fact that Honda will not address the issue. Or admit fault.

Every time I start my Honda Civic hybrid from 2004 it shudders. I have spent more then the value of the car on repairs and fluid replacements which Honda does not deem necessary to pay for. This car is a dangerous lemon. It sometimes shudders going onto highways and can even just stop before starting up again. I have had near accidents dozens of times because of this faulty car. Honda made a bad car and even though people complain about it they will not issue a recall. Each time they issue a warranty bonus to try to fix the problem the whole thing either gets worse or slightly better for 1000 miles. I feel like I'm dealing with a no good used car salesmen trying to bate and switch a hybrid. But this car was bought direct from Honda. There needs to be accountability. I guarantee you that all users of 2003-04 Honda's would be a part of this case as it is a pervasive issue among the majority of hch users. We are all angry, we all asked Honda for help and we got no response. We are now looking to governmental intervention. Please help us avoid accidents, lemon cars, and misleading advertisement.

Ima for engine is in degraded state. Told the batteries are failing and need to be replaced. However, car is supposed to be under warranty until 80,000 miles, now @85,428. Problem with the ima batteries is a known problem, yet Honda does nothing to resolve issues with multiple ima issues. Google Honda Civic hybrid ima battery 2004. If one lives in California, the battery warranty goes to 150,000 miles. The Honda insight and Honda hybrid civic's ima battery system is similar, but with the Honda insight, 2002-04 insights, but a recall for the identical problem, letter below. This same warranty should be extended to 04 Honda Civic hybrid owners living in AZ, ca, co, fl, ha, nv & tx. Date: May 12, 2006 to: All Honda sales, service & parts managers from: American Honda service division re: Campaign announcement american Honda is announcing a product update to replace certain ima components to help prevent ima battery deterioration. We are also announcing a warranty extension for the ima battery. Currently, this product update and warranty extension applies only to states where there is an abnormally high replacement rate for ima batteries. These states include Arizona, California, Colorado, Florida, Hawaii, Nevada and Texas. In these states, the warranty for the ima battery has been extended to 10 years of 150,000 miles, whichever occurs first.... to verify eligibility for the ima battery warranty extension, you must do a VIN status inquiry. For more information on the warranty extension, refer to service bulletin 06-027: Warranty extension: Ima battery. Customer notification customers will be sent a notification of the product update and warranty extension the week of May 22, 2006. Approximately 4,700 vehicles are affected by this update campaign.... sincerely, american Honda motor co., Inc. Honda automobile division
