Modern vehicles offer more features than ever before, but advanced technology comes with its own set of challenges. In the United States, more and more drivers are reporting problems related to onboard software and infotainment systems — issues that can greatly impact the use, value, and safety of a new car.
According to data from the National Highway Traffic Safety Administration (and reported on SDV Insider), recalls related to technology defects in vehicles may have increased steadily over the years, with an estimated 35% jump from 2023 to 2024.
For California consumers who purchased or leased a car affected by software or infotainment problems, these defects can be more than frustrating.
They can reduce the vehicle’s value, limit its features, compromise both safety and convenience, and lead to time-consuming trips to the dealership. In this post, we’ll break down how software glitches and infotainment failures can affect drivers in California and explore what steps you can take, especially if you think your situation may be covered under California’s lemon law.
Understanding Software Glitches in Cars
With modern cars becoming more reliant on computer-controlled systems, software glitches have become a top reason for owner complaints. Unlike traditional mechanical issues, these problems can affect everything from how the car runs to how you control its features.
Many drivers are surprised to learn that a minor software bug can disable essential components or trigger warning lights, even when the hardware is functioning properly. These glitches can be difficult to diagnose, leading to repeat visits to the dealership without a clear fix.
As vehicle computers continue to evolve, the complexity — and risk — of software defects continues to grow.
Common Types of Software Glitches in Cars
Many software glitches in a car can be difficult for drivers to predict or diagnose, leading to unexpected disruptions. Understanding the most frequent types of software issues can help you recognize early warning signs and take appropriate action. Common software-related issues include:
- Engine control problems, like warning lights or performance issues
- Automatic emergency braking and adaptive cruise control malfunctioning
- Door locks, windows, or climate controls being unresponsive
- Transmission shifting problems caused by buggy software updates
- Over-the-air update failures that disable important vehicle functions
It can be common for a simple update to accidentally disable features or introduce new errors. California drivers, with their active lifestyles and dependence on reliable transportation, tend to notice these disruptions quickly.
Impact on Vehicle Safety and Use
When software glitches lead to unpredictable behavior — like brake failures, stalling, or lost power — basic safety is at risk.
Even issues like malfunctioning warning systems or unresponsive controls can make every day driving stressful, especially for families, seniors, or commuters who rely on their vehicles for work and errands. In a state where highway driving is a daily reality, these defects can have serious consequences.
Infotainment Glitches and Daily Driving
Infotainment systems serve as the digital command centers for most new cars. They handle music, navigation, Bluetooth calls, and a host of other connected features. But when these systems fail, the impact goes well beyond simple problems. Some of the most common infotainment glitches include:
Navigation and Connectivity Failures
Poor GPS reliability, frozen navigation maps, and lost connection to smartphones are top complaints. For California residents who often travel for work or leisure, a malfunctioning navigation system can turn a simple trip into a complex challenge.
Missed turns or inability to call for roadside help are not just frustrating; they can put all nearby drivers at risk.
Audio and Display Malfunctions
Blank screens, echoing audio, or non-responsive touch controls break the link between driver and car.
These failures are disruptive, especially when you count on features like rear-view cameras or voice command for safer, hands-free driving. Local mechanics and auto technicians report a steady influx of vehicles with these problems, reinforcing how common such complaints have become. More importantly a rear camera is a required safety component.
Documenting Software Glitches for Claims
Unlike traditional mechanical failures, software glitches can be sporadic or hard to show during a repair visit.
It’s important to record the exact symptoms, time, and date they occurred, and attempts to reboot or restore functions. Videos, photos, and written logs are especially helpful, even more so if you need to file a lemon law case later.
Always ask for a copy of the repair order and a written description of what was found or done at each dealership visit. Make sure your complaint is accurately documented. Do not allow even minor changes to your complaint.
Typical Manufacturer Responses to Software Issues
Major automakers have started to acknowledge the scope of these problems. They may offer software updates or “patches” as fixes, but repeated failures can indicate deeper defects.
Common manufacturer responses include:
- Issuing over-the-air software updates
- Scheduling in-person diagnostic appointments
- Advising customers to reset or reboot systems
- Offering temporary loaner vehicles during repairs
- Providing written statements that the issue is “under investigation”
- Recommending future updates with no immediate fix available
If issues persist after mitigation attempts, the recurring need for service may strengthen your California lemon law claim. Keep in mind, communication from manufacturers can be vague, or even nonresponsive, leaving the consumer uncertain about the outcome. Some manufacturers may even propose temporary workarounds rather than permanent solutions.
Lemon Law Basics for Defective Vehicles
If your car is impacted by software or infotainment problems, it’s important to know your rights under the Song-Beverly Consumer Warranty Act, better known as the California lemon law. This law protects consumers who buy or lease defective vehicles, holding manufacturers responsible if they can’t fix persistent issues after a reasonable number of opportunities to do so.
Qualifying as a Lemon under the Law
Simply noticing something is off with your vehicle’s software does not automatically qualify your vehicle as a lemon. A vehicle may qualify as a “lemon” if:
- The problem was first reported while the car was still under the original or dealer warranty.
- The defect affects the use, value, or safety of the vehicle.
- The issue was not caused by driver abuse or neglect.
- The manufacturer or authorized repair center made a reasonable number of attempts to fix the problem.
- Or, the car has been out of service for repairs for a total of 30 days or more.
For California consumers, keeping accurate records and sticking to required service appointments are key. If the software glitches cannot be fixed after multiple servicing attempts, you may be eligible for a lemon law claim.
How to Start a Lemon Law Claim for Software Glitches
The first step in starting a lemon law claim in California is gathering all relevant documentation. This generally includes:
- Your car’s warranty terms
- Proof of purchase or lease agreement
- Vehicle registration documents
- Detailed record of all reported problems
- Repair attempts – including dates, symptoms, repair orders, technician name, etc.
- Communications with the manufacturer’s representatives
- Receipts for any out-of-pocket expenses related to repairs or towing
Next, get in touch with a California lemon law attorney with experience in software glitches. Additionally, check to see if they have experience negotiating with the manufacturer of your vehicle.
An experienced attorney can help you manage the claims process related to technology-related defects and make sure your documentation is thorough. They may also be able to expedite your claim by leaning on prior experience with similar cases.
Don’t hesitate to ask for references or case results that demonstrate their success with software-related lemon law claims.
