Door-handle water intrusion recall (57J9)
On 2021-2024 ID.4s, water can seep into the exterior door-handle circuit board and make a door unlatch on its own while driving. Recall 57J9 inspects and replaces the handles and updates software, free of charge. Ask for proof it was completed, and wiggle each handle checking for looseness or moisture. Out of coverage, a replacement handle runs about $300-$600.
Ask for repair records covering this item. If it hasn't been addressed and the car is in or near the mileage window, price the up to $600 repair into your offer — or make it the seller's problem.
