Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Lexus GX460 & toyota 4.6l exhaust manifold cracks and potential carbon monoxide poisoning. The symptoms I identified were a diesel-like clatter on cold start which went away when the engine warmed up. I did feel above normal fatigue when sitting in the car for long periods. My multiple repair attempts with the Lexus dealer should be documented with Lexus. Lexus and toyota 4.6l v8 exhaust manifolds have chronic cracking problems. …”
