Q: Could this trigger a suspension warning on my Model S?

It can on some cars. Because of Tesla’s factory software calibration variances, a few vehicles show a visual “Suspension may not be level” message after install. That visual warning does not affect drivability and many owners accept it. If your car instead sounds an audible chime with the warning, we recommend uninstalling and returning the kit, since that condition may not resolve on its own. There is no way to know in advance which cars are affected.
