Does the warranty get void if something happens to the car by using a third-party charging adapter?
That would all depend on what happens, and why.
It could I guess.
As I've mentioned elsewhere, I've had the luxury of being able to use
only genuine Tesla charging equipment for my modest needs. (Others, traveling long distances and in more out-of-the-way areas have understandably relied on beneficial third-party charging equipment.)
Despite my own personal choices, I seriously doubt that the use of a legitimate third-party charging product (as
listed here and elsewhere) would under normal circumstances be grounds for voiding a Tesla warranty. (Were there a problem, I imagine that the burden would ultimately fall on Tesla to prove that an aftermarket device actually caused a specific issue.*) Logically, electric car manufacturers probably
all have to accept and even depend on third-party charging equipment. Consider this analysis:
Charging a Tesla in North America at a home or a business using an AC wall outlet involves the following basic systems and mechanisms:
- Electrical grid, to...
- Circuit breaker panel, to...
- Individual circuit breaker, to...
- House wiring, to...
- Wall outlet/receptacle, to...
- Optional (upstream) adapter, to...
- Mobile charging connector/cable, to...
- Optional (downstream) adapter, to...
- The car's charge port, internal circuitry, (AC-to-DC) charger, and batteries.
(Substitute a Tesla or third-party wall connector with cable for Categories 5-7, if desired.)
(Leaving solar roofs and power walls out of the conversation) Tesla can have direct say so
only over items
it manufactures in Categories 6 through 9. But as we know, there are many, many non-Tesla products and mechanisms successfully and safely used in Categories 1 up to 8.
Similarly, charging at AC (Level 2) and DC public charging stations involves the electrical grid, third-party charging station equipment (including the dispenser, cable, and plug),
optional (J1772, CHAdeMO, or CCS1) adapters, and the car's charging mechanisms. If the station is third-party (and not a Supercharger), Tesla and its drivers
must already depend on at least some non-Tesla engineering (a truism).
The point is, the precedent has already been established. Electric car owners
have to depend on non-Tesla equipment at some point in any overall charging procedure (admittedly least with Supercharging). In all or almost all scenarios, Tesla has to and already does depend on third-party mechanisms and services; it always has (starting with the original roadster).
I haven't read the fine print anywhere, but it seems to me that Tesla offering its own J1772, (previously) CHAdeMO, and (now) CCS1 adapters for sale is tantamount to giving official approval to third-party charging station networks and hence, by logical extension, to the use of (responsibly-made) third-party charging products in general. Let's face it;
all car manufacturers tolerate and sometimes embrace aftermarket accessories and parts. (The level of toleration varies on a case-by-case basis, naturally. Tesla's alleged dissatisfaction with the original SETEC CCS1 adapter may be a case in point.)
Just as it is for NEMA 14-50 wall receptacles, interior LED lights, wheels and tires, and countless other products, it is up to the owners as to whether to rely on factory or on third-party products.** In extreme cases, where for example safety or damage is at stake, I would expect Tesla to object in some appropriate way, to a particular aftermarket product. Barring that, you are probably good to go.
