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.

2004 Nissan Frontier Owner Comments

problem #1

Frontier 4WD 6-cyl

I have a 2004 Nissan Frontier crew cab. The normal crusing RPM is around 2300 on the highway. On the initial date of 6/25/2004, I began to note that when the vehicle was operating on cruise control, during a downshift into a passing gear, such as climbing a grade, the motor increases to 3500 rpms. Upon leveling off, the cruise control does not allow the motor to reduce the RPM's back down to crusiing level of 23-2500 RPM. I find myself having to brake or cut off the cruise control to reduce the RPM back to normal. The Nissan dealer in asheville North Carolina has had this truck on 7/1/04, 7/28/04, and 8/11/04 attempting to fix this problem with no success. The last occasion, they kept the vehicle for over two weeks with no luck. On 9/8/04, the service manager advised me that the problem was a bad code that Nissan engineering would have to resolve and he would notify me. Seven months later I've heard nothing so I inquired today while my truck was being serviced. He advised that there is still no fix and he has a list of six customers with the same problem/complaint. The acs control module was replaced as well as the actuator and a relay with no success.
