Q: I have heard these can trigger a suspension warning. Is that true?

On some cars, yes, and we state it plainly. Because of Tesla’s factory software calibration variances, certain 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 also produces 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.
