2019 G70 (6 documents), 2022 G70 (4 documents), 2020 G70 (4 documents).
Does P0088 on a Genesis mean it is recalled?
No. Recalls are filed by campaign and matched by VIN; no recall is triggered by a scan tool. Check the VIN at nhtsa.gov/recalls, or open the model year's page here for the campaigns filed against it.
