Check the conditions before blaming the car.
Electric vehicles can behave differently depending on temperature, driving habits, charging conditions, software settings, and the way a vehicle is used. When something unexpected happens, it is not always easy to tell whether the behavior is normal, a setting needs attention, or a genuine problem requires further investigation.
At The EV Problem, we help Tesla owners and prospective EV drivers make sense of these everyday questions.
Why is your Tesla losing charge while parked? Why is home charging slower than expected? Why does the estimated range change in cold weather? Why did your phone key stop working after previously connecting without trouble?
These questions deserve more than guesswork or an immediate recommendation to replace something.
Our approach is simple: identify the situation, check the relevant conditions, investigate the simplest explanations, and determine what the available evidence actually supports.
The goal is to help you understand your vehicle, make better-informed decisions, and know when it is time to contact Tesla Support or a qualified professional.

Andrew Keaton
Independent Tesla & EV Technology Writer
I'm an independent EV technology writer based in Seattle, Washington, focused on the practical questions that arise when people use electric vehicles every day.
My work explores Tesla charging behavior, battery and range estimates, software updates, vehicle settings, phone-key connectivity, climate control, navigation, and the differences between expected behavior and potential faults.
I approach these topics by examining the variables that may influence the result. Temperature, recent driving, battery state of charge, charging equipment, software version, vehicle configuration, and connected-device settings can all matter, depending on the issue.
Rather than jumping to a conclusion, I work through the available documentation, relevant specifications, calculations, and other reliable information to explain what may be happening and what a reader can reasonably check next.
I'm not a Tesla engineer, employee, or insider. My credibility comes from careful research, transparent reasoning, and a willingness to acknowledge uncertainty. I distinguish documented facts from calculations, observations, and possible explanations instead of presenting every plausible cause as a confirmed diagnosis.
When the available information is not enough to establish what is wrong, I explain what remains uncertain and which additional checks or professional support may be necessary.
Why I Created The EV Problem
Electric vehicles introduce a different set of questions from those many drivers are accustomed to asking about traditional vehicles.
A battery percentage can change while a vehicle is parked. Estimated range can decrease even when the battery itself has not developed a fault. Charging speed can vary with the charging equipment, battery conditions, temperature, and other factors. A software update can also change settings or the way a feature behaves.
Understanding these situations requires looking at the conditions surrounding the vehicle, not just the symptom itself.
I created The EV Problem to make that process easier for ordinary drivers to follow.
Instead of treating every unexpected change as a defect, we ask:
What exactly happened, and when did it begin?
Which Tesla model, hardware configuration, or software version is involved?
What were the temperature, charging state, recent driving, and other relevant conditions?
Could a setting, connection, or change in usage explain the behavior?
What can be checked safely without introducing unnecessary risk?
What evidence would justify contacting support or seeking a professional assessment?
These questions do not assume that every problem has a simple explanation. They help separate what can reasonably be checked from what remains unresolved.
That distinction matters. It can prevent unnecessary worry, reduce unproductive troubleshooting, and help drivers recognize when a problem deserves more attention.
What We Cover
1. Everyday Tesla Problems
Understand what changed before deciding what is wrong.
Everyday ownership can involve unexpected battery use while parked, Tesla App connection problems, phone-key failures, navigation issues, and climate-control behavior that does not match expectations.
Our troubleshooting guides help readers identify the relevant conditions, review appropriate settings, and work through practical checks in a logical order.
We consider factors such as connectivity, recent usage, software behavior, and vehicle settings where relevant. We also distinguish between a possible explanation and a confirmed cause.
The objective is not to promise a universal fix. It is to help you narrow down the possibilities and identify a sensible next step.
2. Tesla Charging & Range Lab
Understand the variables behind charging speed and driving range.
Charging and range are among the most important parts of everyday EV ownership, but the numbers can be easy to misinterpret.
Our guides explore home charging, Supercharging, charging costs, winter range, daily charging limits, and the difference between rated range, displayed estimates, and real-world driving results.
Where calculations are useful, we explain the assumptions behind them. Charging-cost estimates may depend on electricity rates, charging losses, and the amount of energy supplied. Range comparisons may depend on temperature, speed, route, climate control, and driving conditions.
We do not treat one estimate as a universal promise of what every driver will experience.
Instead, we help readers understand which variables matter, how to make more useful comparisons, and what information is needed for a more realistic estimate.
3. Tesla Software & Settings
Know what a feature does, what affects it, and where its limits begin.
Software influences many aspects of Tesla ownership, from vehicle settings and navigation to scheduled charging, climate preconditioning, and Sentry Mode.
Our articles explain relevant features in practical terms, help readers investigate update-related changes, and identify settings worth checking when something behaves unexpectedly.
We also cover driver-assistance features, including Autopilot and Full Self-Driving (Supervised), with particular attention to their limitations.
These systems must not be treated as fully autonomous driving. Drivers remain responsible for monitoring the road, following applicable requirements, and being ready to intervene as necessary.
Feature availability and behavior can vary by vehicle, hardware, software version, region, and other conditions. We make those distinctions clear when they affect the guidance.
4. Long-Term Use & Ownership
Make informed decisions about maintaining and using your EV over time.
Long-term ownership involves more than charging the battery and watching the range estimate.
Battery-health questions, routine maintenance, tire condition, cabin filters, seasonal preparation, charging habits, and road-trip planning can all influence the ownership experience.
Our guides help readers distinguish ordinary variation from changes that may deserve further investigation. We also explain when a change in routine may be sufficient, when additional information is needed, and when contacting Tesla Support is the more appropriate next step.
We do not assume that every range change indicates battery degradation or that every unusual behavior requires a repair. Equally, we do not dismiss persistent warnings or potentially serious problems without appropriate evidence.
The aim is to help you make decisions based on the circumstances rather than fear or guesswork.
Our Condition-First Approach
Every problem has a context. To understand it, we follow a consistent process.
1. Define the Situation
We identify the symptom, relevant vehicle details, software version where applicable, and the circumstances in which the issue occurs.
2. Check the Variables
We examine relevant factors such as temperature, state of charge, recent driving, charging equipment, settings, network connectivity, and usage patterns.
3. Test the Simple Explanations
Where appropriate, we start with safe, reversible checks that can help narrow down the possibilities without introducing unnecessary risk.
4. Explain the Evidence
We distinguish official documentation, calculations, observations, and hypotheses. If the evidence supports only a possible explanation rather than a confirmed diagnosis, we say so.
5. Know When to Escalate
We explain when a reader should stop troubleshooting, consult the applicable owner documentation, contact Tesla Support, or seek assistance from a qualified professional.
This process is designed to make troubleshooting more systematic. It does not guarantee that every issue can be diagnosed remotely or resolved through settings alone.
Our Editorial Standards
At The EV Problem, practical advice must be grounded in evidence and presented with appropriate limits.
Conditions before blame. We consider relevant operating conditions before attributing unexpected behavior to a vehicle fault.
Evidence before diagnosis. We separate documented facts, calculations, observations, and hypotheses. We do not turn an unverified possibility into a definitive conclusion.
Accuracy over generalization. Tesla models, battery configurations, vehicle hardware, software versions, and regional settings may differ. We avoid applying one vehicle's behavior or specifications to every Tesla.
Realistic range and charging guidance. We distinguish rated figures from displayed estimates and actual driving outcomes. Where estimates or calculations are provided, we explain the assumptions that affect the result.
Safety before convenience. We do not encourage readers to open high-voltage battery systems, handle high-voltage components, bypass safety protections, or perform hazardous electrical repairs. Safety-critical issues should be handled through appropriate professional channels.
Responsible driver-assistance guidance. We explain the limitations of driver-assistance features and never present them as a substitute for an attentive, responsible driver.
Useful guidance before traffic. We aim to solve real ownership problems rather than publish alarmist headlines, repetitive content, or unsupported claims designed to attract clicks.
We also do not invent personal testing results, long-term battery measurements, ownership experiences, or access to Tesla's internal information. If an article uses a calculation or hypothetical example, its assumptions should be clear.
Built Around Everyday EV Ownership
Electric vehicles are used in many different circumstances: commuting, family schedules, wet or cold weather, home charging, apartment parking, and longer road trips.
Those circumstances can change the questions drivers need to answer.
A charging routine that works for one household may not suit another. A range estimate that seems reasonable in one set of conditions may change considerably in another. A feature that appears straightforward in a manual may require additional context when used alongside other vehicle settings.
My interest in household energy planning, route comparisons, and practical research informs the way I approach these questions. I prefer to break a complicated issue into smaller variables, identify what can be verified, and explain the next step without unnecessary technical language.
Family schedules and everyday travel also remind us that EV guidance needs to be practical. Drivers need information they can use to plan a journey, understand an unexpected change, or decide whether a problem needs attention—not just a list of technical specifications.
The goal is to make EV ownership easier to understand, one question at a time.
Independent and Unofficial
The EV Problem is an independent automotive and EV technology publication. It is not affiliated with, endorsed by, or operated by Tesla, Inc.
Tesla, vehicle model names, and related trademarks are used for identification and informational purposes. Features, specifications, charging behavior, and software interfaces may vary by model, hardware, region, and software version.
Our articles provide general educational information. They do not replace the applicable owner's manual, official Tesla guidance, professional vehicle inspection, or qualified service when a problem requires further investigation.
When a situation involves a safety warning, a potentially serious vehicle fault, or high-voltage components, readers should prioritize appropriate support over continued DIY troubleshooting.
Check the Conditions Before Blaming the Car
An unexpected change does not automatically mean something is broken. But it should not be dismissed without considering the evidence, either.
The useful next step is to understand what happened, check the conditions that may explain it, and determine what the available information can—and cannot—confirm.
That is the principle behind The EV Problem.
Check the conditions before blaming the car.
