Early Warning Signs Your Car Gives You Before You End Up Needing a Tow
Modern vehicles, especially EVs and hybrids, are experiencing more software, electrical, and mechanical issues, making early warning signs more important than ever. Ignoring dashboard alerts, leaks, strange noises, or performance changes can quickly turn small repairs into costly breakdowns within days.
When driving your car, you may assume that your car is fine as long as the engine starts, the car accelerates and you get where you need to go. You’re pretty confident your car is working and everything seems fine because you’re able to get from point A to point B safely and as per your routine. What you might not be aware of are the early warning signs that you might be ignoring that could lead to a breakdown when you least expect it.
While breakdowns may seem sudden, they may have been warnings you might have missed because everything has been going pretty smoothly. According to recent automotive data, 64% of vehicles with early engine battery faults become undrivable within just one week of the first symptom, especially in models like the Nissan Juke, where battery and engine issues are common.

Furthermore, ignoring early warning signs doesn't just lead to breakdowns but also multiples your repair costs up to 300%. A tiny fluid leak that could cost a few hundred dollars to repair today could turn into a $2,500+ transmission failure if left unstreated. [ConsumerAffairs, 2025]
As newer vehicles - especially EVs and hybrids - become more software-driven and complex, early attention is the most important factor in preventing a tow and burning a hole in your wallet.
Why Do Early Warning Signs Matter?
Today’s vehicles are experiencing more problems than in the last decade. The numbers below tell us one thing: modern vehicles are extremely sensitive to early warning signs.
- According to JD Power, the industry average for problems per 100 vehicles (PP100) has risen to 202, the highest since 2009.
- 36% of Volkswagen ID.4 owners report problems, and two-thirds lose the car for over a week. Additionally, Mercedes C-Class (2021+) owners report a 43% issue rate, with only 19% getting repairs completed within a day. [What Car?, 2025]
- CarEdge stated that EVs and plug-in hybrids experience 42% - 70% more issues than gas-powered vehicles.
- Major repairs average $2000 - $4,500, with transmissions alone averaging $2,800 according to Consumer Affairs.
Early Warning Signs to Pay Attention To
Here are some early signs to watch out for to repair your car or get it serviced in time to prevent a breakdown.
- Dashboard Warning Lights
These lights, especially if they don’t go away or keep flickering, are extremely important to watch out for when you start your car or when you’re driving. Search engine lights, battery or even temperature lights are your car's attempt to tell you that something is in trouble. In 2025, JD Power reported a 6% increase in software-related vehicle problems, which often show up first as mysterious dashboard alerts.
Some drivers may think these lights are glitches at first, but the truth is that software problems are now one of the leading causes of mechanical failures. Therefore, any warning light that appears on your dashboard, especially more than once, should be given immediate attention.
- Electrical Glitches and Slow Cranking
Electric vehicles rely on a traditional 12V battery for startup and core systems and when this fails, the car becomes undrivable, even if the high-voltage battery is fully charged. Studies show that 12V battery failures are one of the top reasons for EV immobility across brands like Nissan, Mercedes, and Volkswagen. [What Car?, 2025]
Here’s what to watch out for:
- Dimming lights
- Screens freezing
- Infotainment rebooting
- Delayed engine turnover
These are all signs of electrical instability and should definitely not be ignored.
- Leaks Under the Car
Fluid leads almost always precede mechanical failures. And yet, you would be surprised to know that this is one of the most commonly ignored warning signs.
Types of Leaks to Be Aware of
- Transmission Fluid Leaks
It doesn’t matter if the leak is tiny or big, any small learn can turn into a transmission meltdown as few as 200 miles.
- Coolant Leaks
Consumer Affairs reported that a Virginia driver ignored a coolant drip in a 2022 Ford F-150 and ended up with a $3,200 engine replacement - a repair that would have only cost $200 if caught early.
- Brake Fluid Leaks
Brake fluid leaks can cause a total brake failure without any warning. [Knobhill Towing, 2025]
- New Noises, Vibrations, or Drivability Changes
Grinding, clunking, squealing, or clicking noises are not to be ignored. These are early signs of misalignment, failing brakes, damaged suspension components, or engine issues.
Low-speed collisions can also create invisible frame damage, which can later lead to premature wear on steering, tires, and suspension, according to AAA Towing.
Trust your instincts; if your car suddenly feels different to drive, something is definitely wrong.
- Overheating or Fluctuating Temperature
Something to note, engines rarely overheat out of nowhere. Temperature fluctuations are the first sign that:
- Coolant is leaking
- A water pump is failing
- A thermostat is stuck
- Fans or sensors are malfunctioning
Ignoring these signs, even for a brief moment, can result in catastrophic engine failure.
- Spongy, Weak, or Noisy Brakes
Your brakes give multiple early warnings even before a system failure. Here are some signs:
- Pedal sinking
- Squealing
- Vibration
- Car is pulling to one side
Because brake fluid leaks can lead to instant failure, experts warn against driving with suspected brake issues.
- Infotainment Failures, or Software Glitches
2025 showed infotainment as the number one failure point for many luxury brands. In some Mercedes models, software bugs account for nearly one-third of all reported problems, according to What Car?, 2025.
When the car’s software stumbles, the systems it controls, like the backup cameras, sensors, navigation, and autonomous features, can often fail. JD Power says that drivers don’t realize that their car’s computer is the new weak link.
- Hesitation, Rough Shifting, or Reduced Acceleration
Be aware of sluggish responses. These could indicate:
- Hybrid or EV battery management issues
- Transmission slipping
- Sensor failures
- Throttle problems
Plug-in hybrids are especially prone to these issues - they experience 7-% more problems than gas vehicles according to CarEdge, 2025.
Industry Trends Drivers Should Know
A few trends all drivers must know to protect themselves from breakdowns and exceeding repair costs.
Software is the #1 cause of car problems: JD Power states that mass market brands saw a dramatic rise in software defects in 2025.
EVs and hybrids experience higher failure rates: EVs have 42% more issues, while hybrids experience 70% more issues, according to CarEdge, 2025.
Recalls are surging: CarEdge also stated that GM alone recorded 34 recalls in 2025, mainly due to electrical and software defects and not mechanical failures.
Repair times are getting longer: What Car?, 2025 showed that 64% of Nissan Juke owners and 41% of Mercedes C-Class owners were without their cars for a week or more.
Key Takeaway: Don’t Ignore Early Signs
It’s crucial to be aware and take action immediately when you think there is a problem with your car, the moment something doesn’t feel right. Don’t gamble with warning signs because a $200 repair could become a $3,000 breakdown within days. Additionally, take note of warning signs as your car will alert you before it breaks down.
