That's what the https://en.wikipedia.org/wiki/Magnuson%E2%80%93Moss_Warranty... is for.
This is a complete hack job and I doubt there is a single component related to the electrical system that wouldn't be an easy denial from Honda unless the dealer played along... and in a modern car so much is tied to the electrical system that, while technically they didn't just void their entire warranty, they did just gut it to the point of being nearly useless.
Half a tank of gas later, Dealer B claimed the warranty was void because of the camera. We brought it in because the radio kept freaking out and it would drain the battery if left off over night.
There was an active recall for both those issues. Dealer C fixed them by installing a firmware update.
We also had a good time at a Toyota dealership, but any car buying with them had a $6290 markup....
Given the state of the market, choosing between many cars wasn't an option, but outside of that, I care that the process is fast, there aren't sneaky charges, and the interaction is respectful. I prefer all my paperwork printed out, and that's what they did by default.
The dealership had previously repaired the moon roof, and inadvertently damaged the headliner. So, while working on the emissions issue they replaced the whole headliner. The replacement is a little cheesier than from the factory, but good enough.
There's still an exterior rattle that they claimed they fixed 3 times now. At least they're trying. Last time I took it in, they removed several trim pieces and drove it around. I'm just going to have to track it down myself I guess.
I bought a new Mustang in 2010, and paid for the 5 year extended service plan. The hood paint corroded and the dealership repainted it, and gave me a rental car for the week. The hood has since corroded again and it's out of warranty now. I am mulling over splurging on a new paint job, with a classic Mustang racing stripe.
Buying the Mustang, I went to three dealerships. The first one, I got a test drive, and then the salesmen just walked away. I think he assumed I wasn't serious when I said I was buying a car that day. The second dealership, the salesman was super sleazy and pushy, and so I walked away. The third dealership, the salesman was really relaxed and professional. He asked if I was financing, and when I said no, he said he didn't like to waste time haggling and was happy just to move inventory. He offered me a price just $200 above the friends-and-family x-code price.
When your 800$ laptop's speakers start buzzing and the service center says you need to pay 80$ for the repair because the tamper seal on the RAM was broken, are you really going to spend 30k and a year of your free time to sue them over it?
They know that as well as you do. I've found they usually do more passive aggressive / ambiguous stuff than overtly break the law.
Once we had a Toshiba laptop with a bad motherboard. They replaced it with some other board that didn't have drivers for Linux, or even for Windows.
Lenovo took over thirty days to repair my IBM thinkpad (broken screen connector), and when it came back, the high voltage screen transformer was shorted to the case, so it shocked the heck out of me when I turned it on.
On top of that, they didn't replace the broken screen connector, and claimed it was "no fault". This was after the local lenovo repair people found the fault, and lenovo said they couldn't ship the required part.
Are there no small claims courts where you live? Ombudmans? It really isn't a huge deal, nor is it very expensive. It's not 30k - more like $50. And not a year, usually few weeks at most.
>>? If the manufacturer says your warranty is void - it is.
No, it isn't, that's the whole point.
I once caught a motherboard on fire, then found some unrelated mechanical issues with it. (It still worked, except for the bad connector.)
The burn marks were cosmetic, and the shop sent me a DOA replacement. (That's more a story about the shop being awesome, but they were technically legally obligated to honor the warranty.)
