Tesla Model 3 Repair & Service in Worcester, MA

Regenerative braking does most of the stopping, so the friction brakes barely wear — and in a salt state that is the problem. Slide pins seize and pads stick while they still look new, which shows up as a grinding noise, uneven pad wear or a drop in range. Tesla’s own schedule calls for the calipers to be cleaned and lubricated every year in salt-belt states; we do exactly that.

Front upper control arms and their ball joints are a well-known noise source on the Model 3, especially over speed bumps and on cold mornings. We find the noisy joint on the lift and replace the part that is actually worn, then align the car.

When the 12-volt or low-voltage battery weakens, a Model 3 may refuse to wake, lose its door handles, or show a battery warning — even with a full high-voltage pack. We test it under load and replace it with the correct type before chasing anything else.

Alerts like a fired pyro fuse or contactor and precharge faults need inspection, not just a part. A pyro fuse is a one-shot safety device that does not blow on its own, so we look for the reason it fired first — on one Model 3, a chafed high-voltage cable that was still shorting.

Instant torque and a heavy battery wear tires quickly, and a slightly-off alignment wears the inner edges fast. We rotate, balance and align to Tesla specification and read the tread for early warning signs.

The battery pack forms most of the floor, so a Model 3 must be lifted only at its designated lift points with the right pads. A floor jack under the pack can damage it. Every Model 3 goes on our lift the way Tesla specifies.
