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

“I have a 1998 Lexus ES300 with approximately 115,000 on the car. The check engine light recently came on stating that it was emissions code p0466, which is a common charcoal cannister problem for Lexus ES300 1996 and up. There was an extended warranty issued for 1996-1998 Lexus ES300 for the emission problem which includes the p0466 problem. I went to the Lexus dealer to get that emissions problem fix, but they said that not all of the 1998 Lexus ES300 was included in this warranty and my car was one of the cars that was in that category. …”

“I have a 1998 Lexus ES300. In november 2003, my car was serviced under Lexus' spa program due to engine oil gelling/sludge. Now, 3 years later, the engine seized. This is a direct and consequential result of driving the car for 76k miles with a gelling issue. The damage had been done and this was a latent defect. We took the car to the Lexus dealer and had it serviced three weeks ago, spent $700 on it, drove it off the lot and 20 minutes later the engine seized. They now want $5k to put a used engine in it with 130k miles on it. …”
