What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2021 Lexus IS 300, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

From owner reports, verbatim
The Oil Housing Cap cracked during an oil change on my 2021 Lexus IS300. This occurred at my mechanics shop. I would have taken the car to the dealer but the cost for an oil change is double. The mechanic charged me for the part $55.25. When he went to purchase the part from JM Lexus, Sample Road, the parts person said this is a problem that should have been resolved. I called the Parts Manager at JM Lexus to verify this information. He stated that the part is weak and cracks and that this part needs to be replaced a few times a month. I wrote to the Executives at JM Lexus and they refuse to reimburse me because the car was not serviced there, however, the bigger problem is that this part needs to be retooled and owners recalled for replacement. For those in cold weather, could this part crack and leak oil? Will I be charged every time I get an oil change because of this defect?
Too few reports in this category for a page of its own — they appear in the full complaint list.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
