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.

1998 Acura TL Owner Comments

problem #1

Jan 102008


  • 100,000 miles


My 1998 Acura 2.5 TL has had noticeable exhaust leak into the passenger compartment from about 100,000 miles point, since January 2008L about one year ago. All the outside smells come right in even though I always have vents and air cond or heater set to "inside air only" setting. Along with exhaust I smell the catalytic converter odor, refinery odor when I drive past refinery, skunk smell when I drive over even a spot where a skunk was removed a few days ago, etc and also the check engine light came on a year ago, as many other owners have reported, I had it diagnosed as failed oxygen sensor but it seems that goes with the cracked engine manifold. This widely reported condition should be a mfgr recall notice. There is no excuse for the failure to recall over this persistent defect. Owners now know that it was the very same problem in 1996 and 1997 where it was a recall notice item; it should be for 1998 as well. I have been the most loyal of Acura owners (this is our fourth Acura as a family) but I and my husband will no longer tolerate such dishonesty in Acura co.
