I Investigated Top 2025 Lexus RX 350 Complaints. Here’s What I Found
Problem analysis of the 2025 Lexus RX 350 found issues including 12-volt battery failure, unintended acceleration with braking malfunctions, and persistent electronics malfunctions affecting safety and comfort.
Key Points
- Lemberg Law reviewed real owner complaints, federal safety data, and its internal records to identify the most common concerns reported by 2025 Lexus RX 350 owners.
- The leading issue involves 12-volt battery failures, with owners describing repeated dead batteries, no-start conditions, and vehicles losing power unexpectedly.
- Other reported concerns include electronics and instrument cluster failures, unintended acceleration and brake malfunctions, door and locking system issues, and exterior or interior defects, and unresolved problems may support lemon law claims for refund, replacement, or compensation.
Lexus has built its reputation on reliability and luxury, so when clients started reaching out about their 2025 RX 350 dying within months of purchase, I pay attention. Dead batteries, unintended acceleration, and instrument panels going blank are not what buyers expect from a vehicle at this price point.
My name is Sergei Lemberg, and I’m a lemon law attorney with over twenty years of experience representing consumers in vehicle defect cases.
As part of our ongoing series on common car problems, I dove into the top issues facing 2025 Lexus RX 350 owners. I reviewed NHTSA data, owner complaints, and our own internal data. As always, it’s worth noting that not all RX 350s will experience these issues. These are simply the most commonly reported defects, likely affecting a small percentage of vehicles.
Let’s dive in.
Most Common Problems
Here’s what my research found:
- 12-Volt Battery Failures: Repeated dead battery incidents causing vehicle shutdowns, sometimes within weeks of purchase.
- Unintended Acceleration and Brake Malfunctions: Sudden unintended acceleration events paired with hard brake pedals and failure to stop safely.
- Electronics and Instrument Cluster Failures: Blank instrument panels, warning lights flashing erratically, and software glitches affecting essential vehicle functions.
- Door and Locking System Malfunctions: Issues with power door locks failing to operate with key fobs, locking owners inside or outside the vehicle.
- Exterior and Interior Defects: Window shattering, cracks on the center console, and noise issues like hood flutter and wind noise reported by owners.
Top Problem #1: 12-Volt Battery Failures
I found numerous reports of the 12-volt battery failing prematurely leading to a complete loss of vehicle power. This is a concern because it can leave drivers stranded unexpectedly. Typical symptoms include:
- Vehicle will not start after short periods of non-use, even when parked indoors.
- Battery voltage reading dangerously low despite being a new vehicle.
- Multiple battery replacements without lasting resolution.
One owner stated
“Car left us stranded 12 V battery completely dead had a lot of difficulty trying to get it started. Problem could not get resolved after installing five batteries.”
Another commented: “Brand new vehicle 12 Volt battery failed after 3 months of operation.”

Top Problem #2: Electronics and Instrument Cluster Failures
Owners frequently report malfunctioning instrument clusters and erratic warning lights that can compromise vehicle safety and operation. Common issues include:
- Instrument panel going completely blank while driving.
- Warning lights flashing uncontrollably with no clear pattern.
- Navigation and display screens freezing or shutting off repeatedly.
- Adaptive cruise control shutting off unexpectedly while the cruise function remains on.
One driver said
“While driving, the instrument panel went blank. I believe it is not safe to drive with no instrumentation or knowledge of your vehicle or speed.” Another shared: “Every time it snows, the car flashes all warnings, parking sensors fail, and systems become unreliable.”
Top Problem #3: Unintended Acceleration and Brake Malfunctions
This issue involves the vehicle suddenly accelerating without driver input, sometimes with the brake pedal feeling unusually hard or unresponsive. Reported symptoms include:
- Sudden unintended acceleration leading to crashes into static objects.
- The brake pedal becoming stiff and failing to stop the vehicle effectively.
- Warning lights fail to activate or provide misleading information during these events.
One affected owner reported
“While driving into a parking space, the vehicle suddenly experienced unintended acceleration and drove forward at a high rate of speed before crashing into the brick wall of an office building, and no air bags deployed ” Another described simultaneous brake and accelerator pedal engagement with a loud engine noise and no warning lights.
What Should You Do If Your 2025 Lexus RX 350 Is a Lemon?
A lemon vehicle typically has a substantial defect that impairs its use, value, or safety and cannot be repaired after a reasonable number of attempts. With that in mind, I advise owners to take these steps:
- Document every issue: Keep detailed records of symptoms, repair attempts, dates, and communications with dealerships or manufacturers.
- File complaints: Submit reports to the National Highway Traffic Safety Administration and your state’s consumer protection office.
- Understand your legal rights: Lemon laws vary by state but generally require multiple repair attempts or extended out-of-service periods.
