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 stated vehicle would not start on two occasions. The vehicle was taken to the dealership, and the fuel injectors were repaired. The second time the vehicle would not start was due to the valve seat. The vehicle could not be repaired. A rebuilt engine was installed into the vehicle.

Exhaust smell from fresh air vents, mainly while idling my 2004 Dodge Ram 3500 4X4 with cummins engine. I noticed the smell within days of purchase, took it to several dealers, and was told they had never experienced this problem before. End suggestion was a citrus oil additive to make the exhaust smell like citrus. (no joke) fuel injector failure, filling crankcase with diesel, causing rough running and eventual oil pressure loss. Dealer, upon advisment from "tech department" changed the oil, replaced the faulty injector and got me out the door. Now I have experienced engine vibrations that are getting progressivly worse, higher engine RPM's increased fuel consumtion, a cloud of blue smoke upon startup after several hours of downtime, and the dealership thinks it may be a wiring harness. I spoke directly to cummins service dept. And was told that with oil pressure loss, they would have dropped the oil pan and checked the bearings.
