Your Tesla Model S has no power on a Valley shoulder. A no-power Model S tow is delicate because the car cannot release its own parking brake electronically, and ARS 28-871 plus the heat make the situation urgent. Here is the checklist to run before the flatbed arrives.
What “no power” means on a Model S
A Model S with no power usually means the 12-volt is dead. The traction pack may still have range, but the small battery that wakes the car up is gone. The car cannot release its own parking brake electronically, and the standard tow mode does not engage.
The fix is the 12-volt first, not the tow. A clean jump wakes the car and lets the parking brake release normally. The tow becomes a normal tow of a working car with a low traction pack.
For the broader view of what a Tesla 12-volt does, see when Tesla 12-volt batteries fail in desert heat and how to tell a Tesla 12-volt is dead in Phoenix.
The checklist to run before the flatbed
Run these in order before you call for a tow:
- Try the mechanical key from the fob on the driver-side door. Pull the handle out, expose the lock cylinder, insert the key blade, and turn to unlock.
- Pull the front tow-hook cover to access the jump posts. The cover pops out with a small screwdriver.
- Connect a jump pack or a properly sized donor battery. Connect the red clamp to the positive post. Connect the black clamp to bare, unpainted metal on the chassis, not the negative terminal.
- Let the donor feed for two to three minutes, then try to power the car up.
- If the car wakes, put it in Tow Mode from the infotainment screen before the flatbed arrives.

When the 12-volt jump does not work
If the car still has no power after a clean jump, the failure is deeper than the 12-volt. A high-voltage fault or a DC-DC converter failure can mimic a dead 12-volt. Do not keep jumping. Call for a flatbed to a Tesla service center.

Arizona law on a freeway shoulder
ARS 28-871 says you may not stop or park on the traveled part of a highway outside a business or residence district if it is practical to get off it. A vehicle disabled so badly it cannot be moved is exempt. When stopped, leave room for other traffic to pass and be visible 200 feet in each direction.
Phoenix heat makes the shoulder dangerous in summer. ARS 28-775 is the Move Over law. Approaching a stopped vehicle with flashing or warning lights, drivers must move over a lane if they safely can or slow down.
If you can safely exit and pull into a side street or shopping center, do that. Off-freeway stops are easier for the operator than a freeway shoulder.
When a mobile operator is the right call
If the 12-volt jump works and the car wakes, a mobile operator can come to you with a Level 2 source and add 10 to 20 miles in 15 to 30 minutes of charging. That is enough to reach a charger you already meant to use.
Charge Pro PHX matches you with an independent local operator. We do not own trucks, employ technicians, or set prices. The operator quotes before any work starts and bills you directly.

What to do if your Model S has no power right now
Get the car as far off the travel lane as you can. Keep hazards on. Have a location ready: nearest exit number or cross street.
Try the mechanical key from the fob. Pull the bumper cover. Connect a jump pack. If the car wakes, drive to the next charger.
If the car still has no power, call (602) 932-0920. The operator confirms whether a 12-volt jump or a flatbed is the right answer, quotes before any work starts, and bills you directly.
Frequently asked questions
How do I tow a Tesla Model S with no power?
Run the 12-volt jump first. If the car wakes, put it in Tow Mode and tow normally. If the car will not wake, call for a flatbed to a service center.
Where is the Tesla Model S 12-volt jump point?
Behind the front bumper tow-hook cover, not under a hood. The cover pops out with a small screwdriver. For the full walk-through, see how to jump a Tesla from the bumper tow hook.
Will Arizona DPS tow my Model S for free?
DPS Roadside Motorist Assistance will change tires, bring gasoline or diesel, jump conventional batteries, and call tows. For a dead EV, it does not advertise bringing a charge.
Does Charge Pro PHX work on Tesla Model S?
Yes. We match you with an independent local operator who carries the gear to open the car, jump the 12-volt from the bumper, and add Level 2 range if needed. The operator quotes and bills you directly.
