Typical repair cost, by problem

The most common problem on this generation is excessive engine oil consumption, with one owner needing 2.5 quarts every 1,300 miles and reports of blue-grey smoke with an unusual odor at 100,000+ miles. Owners also report both headlights failing at once due to ballast failure, a pattern documented on several other Toyota and Lexus vehicles. This generation's NHTSA sample also includes several serious single-case safety reports — including an airbag non-deployment injury, a spontaneous airbag deployment, an engine fire, and unintended acceleration — that are not yet independently corroborated, so they are noted here rather than listed as common problems.
