Pedals on my 2007 Nissan Murano are moving on their on Accord. Appears to be defective wiring. Dealer wants me to pay $315 to fix. They had agreed two years ago to fix the problem when I purchased the vehicle and they never did. This is a serious safety issue.

2007 Nissan Murano. After I lock the doors the windows go down all by themselves. This is a safety issue. It happens all the time a lot of people have this problem with their Murano's. the consumer stated the rear door was closed and appeared to be latched securely when he drove off. However, the door flew open in the middle of the street. Updated IVOQ 04/27/11

Doors can be unlocked and the car ignition can be started without a key, and there is no way to lock the ignition, and no way to stop anyone from opening the doors. This creates an extremely dangerous condition for car jacking and harm to the occupants.

The battery has been replaced twice in the vehicle and it has less than 35,000 miles on it. The first replacement was done when the car was only about 6 months old and I just recently had to have the battery replaced again. The second battery was supposed to be an 84,000 mile battery and was under warranty. However, when I was driving it, the car died on me and would not start again. The battery had less than 26,000 miles on it. Nissan fought us on the replacement even though it was under warranty, but we finally got another one put in. We are on our 3rd battery in less than 3 years. This same vehicle had an engine mount crack at 32,000 miles and has also had the radiator replaced at 34,000 miles. It has been in the shop 4 times now in the last 2 1/2 months. When the radiator went out, the gauges did not even say that the car was running hot. I discovered the issue when my car started smoking everywhere and coolant was all over my vehicle. Nissan insists that it is not an electrical issue of any kind and that the gauge can still read cool if the radiator goes out and the car is smoking. All in all, I now have the 3rd new battery, a new radiator, and a new engine mount. The drive belts have also cracked, but Nissan refused to do anything about that.

The car engine shut down all of sudden while driving at about 60mph on an interstate highway and didn't respond to action on accelerator. The car stopped in the middle of the highway and 2 police cars came and pushed the car out of the highway. The car was then towed to a service center. According to a diagnosis, we were informed that the cause is the failure of the fuse box. Power comes in the fuse box but does not come out. And also we were informed that this failure is uncommon. The part was replaced. However, we are now very concerned about the safety and reliability of our car because the above critical engine failure occurred to our fairly new car while driving. We purchased a new car and the car is a little over 2 years old and its mileage is only about 19K.
