Vehicle report
Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.
ZE7_Warranty Pol
Warranty Policy Bulletin: Toyota has received some reports where vehicles may exhibit excessive engine oil consumption. Toyota is now announcing the part replacement phase of Warranty Enhancement Program ZE7 for vehicles exhibiting excessive engine oil consumption.
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
