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?

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2021 Lexus Is300 verdict →
