Common Issues- Unintended acceleration. The vehicle accelerates independently during braking with a vibrating brake pedal, causing loss of control and crashes in reported instances.
- Automatic emergency braking malfunctions. The system activates brakes randomly at speeds above 40 mph without obstacles present, producing sudden stops that startle drivers.
- Parking sensor faults. Sensors trigger repeatedly and falsely at speeds under 10 mph, often displaying a red alert without the presence of objects.
- Brake pedal vibration. Vibrations occur while braking and releasing the pedal at low speeds, accompanied by sudden acceleration events.
- Chemical odor from engine area. A persistent chemical smell noted weeks before unintended acceleration incidents.
- Delayed recall repair parts. Owners report Nissan recall parts for electrical system issues are unavailable, causing delays in vehicle repairs.
There are 5 recalls affecting electrical and propulsion systems, particularly the high-voltage battery and traction battery components. The recalls involve risks of battery failure, fire, and sudden loss of drive power.
Recalls- High-voltage battery fire risk. (NHTSA Campaign Number 25V050000) Affects 7,362 vehicles including 2022-2025 EQB 250, EQB 300 4MATIC, EQB 350 4MATIC. The battery may internally fail causing vehicle fires while parked or driving. Owners are advised to limit charging to 80% battery capacity until software updates are installed free of charge by dealers.
- Battery bus bar screw defect. (NHTSA Campaign Number 25V487000) Applies to 660 vehicles including 2022-2023 EQB 350 4MATIC and EQB 300 4MATIC.

Owners facing repeated acceleration or braking issues, unresolved recall repairs, or safety defects should consider reviewing their rights under state lemon laws. Persistent vehicle malfunctions or safety risks may qualify for legal protection related to defective vehicles.

ID: 2064195FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
When driving above 40 mph, I have experienced seemingly random brakes, which most likely is due to the automatic emergency braking system. I have seen it work properly when a car cuts me off in traffic, which it makes sense then. But in several instances, it's pumped the brakes when there is no obstacle or car around. It's quite scary since you might get hit from behind. One time it braked so suddenly I was jolted forward in my seat. It also has an issue with parking sensors going off also randomly going under 10 mph. All of them activate on red.
