Let’s Talk About Radar Obstructions

I’ve been dealing with this frustrating issue on my Nissan where I keep getting alerts about ‘Unavailable Front Radar Obstruction’. It seems like every time I’m using the adaptive cruise control or trying to engage the collision avoidance system, the radar sensors throw a fit and stop working.

Common Causes

From what I’ve gathered and experienced, here are some typical reasons why this might be happening:

  • Dirt or Debris: A common culprit! If you haven’t checked, your radar sensors might just be covered in muck – especially if you’ve been off-roading or in bad weather.
  • Water Build-Up: Rain or cleaning your car may also obscure the sensors, leading to malfunction. Make sure they are dry and clean.
  • Physical Obstructions: Anything blocking the front sensor can cause this problem. Take a closer look at your bumper and surrounding areas.

What Can You Do?

Here are a few troubleshooting steps that might help:

  1. Cleaning: Gently clean your radar sensors with a soft cloth. You can use a mild soap solution if they’re really dirty.
  2. Inspection: Check for any visible signs of damage or misalignment. If the sensor housing seems off, it might need reassessment.
  3. Recalibration: Some users have mentioned recalibrating their sensors solved the issue. Refer to your vehicle’s manual for instructions.
  4. Visit a Technician: If all else fails, it might be time for a professional diagnosis. Especially if your sensors are damaged or malfunctioning.

I think aftermarket modifications can really affect radar performance too. I’ve had a few issues since adding some accessories to my vehicle.

You’d think so! It’s disappointing when we’re facing these challenges, especially after spending so much on these cars.

Maybe we should just cover our cars in plastic wrap! It could prevent everything from sticking to the sensors. Just a thought!

It’s worth taking the car into a service center, but I wouldn’t be surprised if they don’t find anything. It seems to be an intermittent issue for many of us.
