Common Tesla Problems and What Might Be Causing Them
Most Tesla problems start small: a noise over bumps, a charge cable that sticks, AC that isn't as cold as it used to be. This page walks through seven common symptoms and what might be causing them, so you have a better idea of what could be going on before anyone picks up a tool.
Every car is different, and a symptom can have more than one cause. Use this as a starting point, not a final answer.
1. Charging cable won't release
You finish charging, press unlock, and the cable stays locked in the port.
Two common causes are water getting into the charge port and its electronics, or a software glitch in the charge port system.
Things to try first: unlock the port from the touchscreen or the Tesla app, and check your owner's manual for the manual charge port release. Avoid forcing the connector out, since that can damage the latch or the pins.
If it keeps happening, we'll check it and tell you honestly whether we can fix it at your location.

2. Suspension keeps making noise
A clunk over speed bumps and driveways, a rattle on rough pavement, or a creak when turning. These noises usually start faint and get louder.
Two of the most common sources are worn ball joints and worn sway bar links. Both loosen with time and miles, and once there's play, you hear it every time the suspension moves. Worn control arm bushings can sound similar, which is why finding the actual source matters before replacing anything.
For more detail on noises, clunks and what's usually behind them, see our Tesla suspension noise repair page.
3. AC stops blowing cold air
The fans run, but the air is barely cool, or it's cold for a few minutes and then warms up.
Two likely causes are a failing AC compressor or a restricted condenser. The compressor pumps refrigerant through the system, and the condenser at the front of the car releases heat. If either can't do its job, cooling drops off.
We'll check it and tell you honestly whether we can fix it at your location.

4. Can't stop in time
The car takes longer to stop than you expect, or you hear grinding on the first few stops of the day. You may also see rust on the rotors through the wheels.
Regenerative braking does most of the slowing down in a Tesla, so the friction brakes get used far less than on a gas car. That's easy on the pads, but rotors that barely get used can build up rust, even here in the Bay Area with no snow or road salt. Rain, morning moisture and days parked all add to it. Calipers can also stick from lack of use.
If your car ever feels unsafe to stop, please don't keep driving it.

5. Tires wearing out too quickly
Your tires wear out early, or unevenly, like a bald inside edge while the outside still looks fine.
Two common reasons are skipping tire rotations and an alignment that's off. Teslas are heavy and quick, which is hard on tires, so rotation matters. If the alignment is off, tires wear unevenly no matter how you drive. Lowering and worn suspension parts can both push alignment out of spec.
If worn or stock arms keep a car from holding alignment, we replace them, for example with an adjustable rear camber kit like the TruHart Rear Camber Kit for Model 3 and Model Y. The alignment itself is done on a laser alignment rack, so we'll recommend a trusted local alignment center to finish the job.
6. Not sure what's wrong with your car?
Sometimes the symptom doesn't match anything above, or it comes and goes. A few things help narrow it down:
Note the details. When does it happen? Cold or warm, slow or fast, over bumps or while turning? A short video of a noise or a photo of a warning message is very useful.
Check what the car is reporting. A free RideRite Health Check shows the alerts and codes your Tesla has stored. It helps point in the right direction, but it isn't a definitive diagnosis.
Describe it in a quote request. Tell us the symptom in your own words and we'll follow up. When we come out, we bring dealer-level diagnostic equipment, and we check warranty status first, so if Tesla should be covering the repair, we'll tell you.
7. Car won't charge
You plug in and nothing happens, or charging starts and then stops.
Often, the car just needs a restart. A reboot can clear a glitch that's blocking charging. Trying a different charger also helps rule out the equipment.
The other common cause is a battery that needs replacing. That's often the 12V or 16V low-voltage battery (depending on model and year), which we can test. It's usually not the big battery pack itself.

Frequently asked questions
Why are the brake rotors on my Tesla rusty?
Regenerative braking does most of the stopping in a Tesla, so the rotors are used much less than on a gas car. Rotors that sit unused can build up rust, even in the Bay Area with no snow or salt.
What causes a Tesla charging cable to get stuck in the port?
Common causes are water getting into the charge port electronics or a software glitch. Try unlocking from the touchscreen or app first, check the owner's manual for the manual release, and avoid forcing the cable.
My Tesla won't charge. Does it need a new battery?
Not necessarily. Often a restart clears it. If a battery is the cause, it's often the 12V or 16V low-voltage battery, which can be tested. It's usually not the big battery pack itself.
What makes Tesla suspension clunk over bumps?
Worn ball joints and sway bar links are two of the most common causes, and worn control arm bushings can sound similar. Finding the actual source matters before replacing parts.
How can I narrow down what's wrong with my Tesla?
Note when the symptom happens, and take a video or photo if you can. A free RideRite Health Check shows the alerts your car has stored, which helps point in the right direction but isn't a full diagnosis. Then describe the symptom in a quote request.
