My vehicle, which I bought used with about 140,000 miles on it had cracked exhaust manifolds, which I replaced. Both were cracked and one actually fell to pieces when unbolted. One replacement cracked after about 15,000 miles, but was able to have it braised. Now, at about 180,000 miles they a spewing carbon monoxide into the cab again. This is a serious health and safety issue, and from checking Titan club web sites, it seems to be a widespread issue. I DO NOT DRIVE OFF ROAD OR SUBJECT THE TRUCK TO ABNORMAL DRIVING CONDITIONS. I appreciate your time and consideration. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
