P0562 on Chrysler by model: symptoms, diagnosis and fix
Both 3.6L and 5.7L engines with 160, 180, or 220 amp alternators prone to sudden failure. Voltage regulator in PCM can fail. Internal diode failures cause battery drain, fires, and loss of power while driving.
Common Symptoms
- Battery warning light illuminated
- Dead battery despite recent replacement
- Vehicle stalling or dying while driving
- Burning smell from alternator area
How to Fix
Alternator replacement with updated unit per recall. Free replacement under recall for affected vehicles. Check PCM voltage regulator function. Verify alternator connections properly seated.

The Sebring's voltage regulator is integrated into the PCM (Powertrain Control Module), not the alternator. This unusual design means a voltage regulator failure requires PCM diagnosis/replacement rather than simple alternator work. Alternators also fail prematurely around 70,000 miles. Ground corrosion and battery terminal strip issues compound the problem.
Common Symptoms
- Battery warning light on dashboard
- Dead battery despite recent replacement
- Headlights dimming or flickering
- Dashboard electrical glitches
- Vehicle stalling due to low voltage
How to Fix
Test alternator output and PCM voltage regulator function separately. Replace alternator (Remy Remanufactured 12423 for 2.7L) if output is low. If alternator tests good, PCM voltage regulator circuit has failed. Clean all battery terminals and ground connections, especially under PCM. External voltage regulator conversion available for chronic cases.

The second-generation 200 suffers from parasitic battery drain caused by modules not going to sleep properly. The Body Control Module and UConnect system are common culprits. Battery can die in 2-3 days of sitting.
Common Symptoms
- Dead battery after sitting 2-3 days
- Needing jump starts frequently
- Interior lights staying on after exiting
- Door lock/unlock cycling on its own
How to Fix
Request latest BCM software update from dealer. Check for aftermarket accessories causing draw. Disconnect negative battery terminal if parking for more than 3 days. Replace battery with AGM type for better cold-weather performance.

On Pacificas built with the engine stop/start system, sealer left on the wire-harness tab during harness manufacturing sits inside the battery ground joint. Over time the sealer creeps and the joint loses clamp load, so the main chassis/engine ground goes intermittent. The high current draw of stop/start restarts makes it worse. Drivers get sudden electrical dropouts: the engine stalls at speed, electric power steering assist cuts out, and a cluster full of warning lights appears. FCA recalled 198,731 vehicles (NHTSA 19V-348, FCA campaign V53).
Common Symptoms
- Engine stalls while driving
- Sudden loss of power steering assist, heavy steering
- Multiple warning lights flash on the cluster
- Stop/start system faults or will not re-fire
- No-crank or intermittent no-start
How to Fix
Have the recall performed: the dealer disassembles the battery ground joint, cleans the contact surfaces and the harness tab of sealer, and reassembles the ground to correct clamp load, free of charge. Out of warranty or if symptoms return, remove the negative battery ground bolt, clean all mating surfaces to bare metal, and torque to spec; inspect the engine-to-body ground strap at the same time. A weak or failing AGM battery amplifies the same symptoms and should be load-tested.

The Pacifica draws an unusually high parasitic current with the vehicle asleep, and the modules can fail to fully shut down - owners document the van entering an unresponsive state where lights and accessories stay powered with no way to switch them off, flattening the battery overnight. Because the van specifies a deep-cycle AGM battery for stop/start duty, short trips never fully recharge it and failures come with no warning, often well inside four years. On the Plug-In Hybrid the 12V auxiliary battery is charged from the high-voltage system, so once it is flat the van cannot boot the hybrid controller at all and the vehicle is dead even with a full traction battery.
Common Symptoms
- No-crank or dead van after sitting a few days
- Battery fails with no prior warning under 4 years
- Random module faults and warning-light storms
- Accessories stay on with the van off
- PHEV will not power up or start charging
How to Fix
Replace with a correct-group AGM battery (never a flooded lead-acid) and register/reset the battery to the body controller so the charging strategy resets. Measure parasitic draw after a full 45-60 minute module sleep - anything well over roughly 50 mA points to a module staying awake (commonly the radio/telematics or a door module). Owners who keep a smart AGM-capable maintainer (CTEK/NOCO) on the van report essentially zero battery failures. On a PacHy, jump or charge the 12V auxiliary battery first before assuming a high-voltage fault.
What you need to diagnose it
The fix here starts with a test, not a part — which repair you need depends on what the test finds.

Testing and isolating the fault is DIY work. Replacing or reprogramming a control module is not — most are VIN-programmed, so a new one does nothing until a shop codes it to your car. Check for an open recall or service bulletin before buying anything.

Frequently asked questions
What does P0562 mean on a Chrysler?
P0562 stands for "System Voltage Low." P0562 means the engine computer detected that the vehicle's system (battery/charging) voltage is too low for normal operation. The computer constantly monitors charging-system voltage because nearly every sensor, injector, and module depends on a stable supply; sustained low voltage can cause erratic behavior and other false codes. This is most often a charging or battery problem — the alternator isn't keeping up, the battery is weak, or there's resistance in the cables/grounds. You may notice dim lights, slow cranking, or multiple unrelated warning lights. On Chrysler it is documented across 4 models: 300, Sebring, 200, Pacifica.
What are the most common causes of P0562?
The most common causes of P0562 are: Failing alternator or worn alternator brushes/regulator, Weak, old, or discharged battery, Corroded, loose, or damaged battery cables and terminals, Bad engine or chassis ground connections, Slipping, glazed, or broken serpentine/drive belt, High resistance in charging system wiring or fusible link, Faulty PCM voltage reference or charging-system control. The specific cause varies by vehicle.
How much does it cost to fix P0562 on a Chrysler?
Published repair estimates on Chrysler range from $200 to $1,000 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
