The lemon law does not yet apply in your situation because they are still troubleshooting the same issue using different techniques. The lemon law would apply if they replaced the stereo three times, each time fixing the issue, and then the same problem occurs again after the third repair for the same failure. You haven't gotten that far yet. I have a similar repair situation in which the HVAC blower fan has failed three times, all the same fault, and Honda has replaced the HVAC blower fan three times. The second repair involved replacing the power resistor/transistor in addition to the blower fan. The fan failed the first month I had the car, Honda replaced the fan. It failed again the following month and Honda replaced the fan with the power resistor. It worked great for 10 months/20,000 miles, then it failed again two weeks ago. Honda has replaced the blower fan again, and can't figure out why it keeps failing. We will see how long it lasts this time. I have an 8 year/100K warranty. I can argue a safety failure because if the fan is failing, I would not be able to defrost the windshield in the winter, causing a safety risk. I am not sure if your failed HondaLink Display would be considered a safety issue. I am annoyed that the HVAC fan keeps failing because I really love my car!
