One "beyond frustrated" Tesla owner took to social media for advice after a car wash exposed a "beta seal failure" which led to a $7,345 repair estimate.
The owner of a used 2022 Tesla Model Y Performance said the car wash exposed an apparent windshield seal failure, which led to extensive damage to the vehicle's electronics.
Here's what to know
The owner shared their story to Reddit's r/TeslaModelY community. According to the Reddit thread, the owner had bought the used Model Y Performance from a Dodge dealership with fewer than 50,000 miles.
The original poster then reported that after the car wash, "all my camera feeds went black," the vehicle showed "an adaptive headlight warning," and it "temporarily lost connectivity." OP wrote, "I bought this car expecting reliable transportation, not a $7,345 surprise repair bill after owning it for approximately four months."
When OP took the vehicle to Tesla, it ran a water-ingress test and found water entering through a compromised "Beta Seal at the bottom-right side of the windshield," which OP said allowed water to reach the computer and corrode connector harnesses.
Later, insurance coverage was denied because the insurer did not treat the situation as a qualifying accidental event, according to OP, who added that the windshield showed no visible damage.

A few commenters suggested earlier damage might be part of the story. One asked whether the windshield had a Tesla logo and said it "may have been replaced recently and the install was incorrect." The original poster, however, replied that "It was confirmed that it has the original windshield."
At least one commenter said the problem didn't match their experience, even with regular car washes. The user wrote, "Have two Teslas now and four over the last 10 years. I always run my cars through automated car washes. I never heard of this problem." That same commenter added, "This feels like a bad used car experience and not a bad Tesla experience."
With a used vehicle, though, responsibility can quickly become unclear when damages occur. If Tesla treats the damage as out of warranty and an insurer declines to classify it as a sudden covered event, the owner may be left trying to determine whether the issue began with the manufacturer, a previous owner, or the selling dealer.
Alongside the dispute over the bill, the OP said they are now "pursuing a formal complaint and asking Tesla to reconsider the repair charges."
Much of the advice focused on the dealership that sold the vehicle. One said, "Your beef should be with the Dodge dealership, not Tesla," arguing that unreported or undisclosed damage may have existed before the sale. Another suggested that proving the corrosion predated the current ownership could help establish hidden damage.
Insurance was another angle raised in the thread. One commenter said, "If water ingress from a car wash caused the damage, you have a comprehensive claim." Other commenters suggested checking whether diagnostics could show deleted or reprogrammed history and looking into warranty options after the repair.
