2021 Toyota Highlander — windshield replaced — does camera calibration matter?

MarketTraveler441Community StarterJan 1, 20262021 Toyota Highlander XLEPhoenix
2021 Toyota Highlander XLE, about 37,500 miles. A new windshield is installed and there is no dash warning, but the shop recommends camera calibration. If the manufacturer procedure calls for it, would you do it even when lane-assist functions appear normal?

Write down what you already tried. A second data point from another 2021 Toyota Highlander owner helps more than a generic diagnosis. Then you'll know the next fork. I'd want that in writing, not as a promise. I'd sleep better after that step, even if it finds nothing. This is the version I'd tell a friend.

Don't overfit one forum story to your car. If it still isn't clear on the 2021 Toyota Highlander, a specialist hour can be cheaper than another round of parts. Then you'll know the next fork. This is from a 2021 Toyota Highlander in Phoenix with 37,500 miles. When does it actually happen? If the story changes I'll post the new data.

That's a good start, but I wouldn't stop there. Verify the cheap/easy branch on the 2021 Toyota Highlander before a big repair or a big spend. I'd do that before spending real money. Verbal 'we'll take care of it' is not a plan. I'll update if anything new shows up.

Owner notes beat generic advice here. On the 2021 Toyota Highlander in Phoenix, I'd fix the thing you'll notice every day before chasing spec-sheet extras. I'd do that before spending real money. On “windshield replaced — does camera calibration matter,” that was the fork that mattered for me. I'd want that in writing, not as a promise. This is the filter I use when the thread starts repeating itself. Wrote this up on my lunch break.
