“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. …”
NHTSA complaint #10260960, filed 2009-03, 100,000 miles“I own an Acura 2.5 TL model year 1998. I was informed by dealer last year that there was an exhaust manifold leak in the engine. The dealer quoted $2000 to fix the problem. I have not had it fixed so far, but I fear that the exhaust fumes were infiltrating the cabin, and we were breathing exhaust fumes when in the car. Upon further investigation I found that this problem was also reported widely in earlier model years.”
NHTSA complaint #10191197, filed 2007-05, 50,000 miles“Exhaust system on my 1998 Acura 2.5 TL has a crack in the exhaust manifold. I've been told the manufacturer replaced this on the 96 & 97 TL's but will not for the 1998. I understand from research there were no changes to the body style or engine between the 96 -98 so why won't they cover the 98?”
NHTSA complaint #10106272, filed 2005-01, 73,462 miles“Auto technician has determined that 1998 Acura 2.5 TL has a cracked manifold. Same vehicle from 1995-97 has been mandated by NHTSA to have this repaired by manufacturer. I would like my vehicle year to be included in this mandate.”
NHTSA complaint #10128711, filed 2005-07, 77,500 miles“Exhaust system on the 1998 Acura 2.5 TL. I have had to have the o2 sensor replaced and now as told the exhaust manifold is cracked. I was aldo told by the dealer that there have been a number of cases were the manifold cracked. If this is a problem that you see repeated in a particular vehicle is it not fairly safe to say there is a problem from the manufacture? What can be done to save consumers the expense of about $1200.00 to repair what seems obvious to be a manufacturer defect with the exhaust system?”
