What does radar obstruction mean for the 2021 CR-V?
3 Answers
Radar obstruction is generally caused by issues with the probe or wiring, which can be thoroughly inspected at an auto repair shop. It is recommended to check if there are any obstacles on the radar or if it is too close to an object. Of course, some car owners may also encounter this problem after modifications. Here is some additional information: 1. The 2021 Honda CR-V is a compact SUV: The second-row seats support proportional folding, which can effectively expand the trunk space when folded down, making it very convenient to use. 2. The manufacturer of the 2021 Honda CR-V is Dongfeng Honda: Dongfeng Honda Automobile Co., Ltd. was established on July 16, 2003, with its headquarters located in the Economic and Technological Development Zone of Wuhan. The company is jointly invested by China Dongfeng Motor Group Co., Ltd., Honda Technology Research Industry (China) Investment Co., Ltd., and Honda Technology Research Industry Co., Ltd. of Japan.
When driving a 2021 CR-V, seeing the radar blocked warning means the front sensors of the vehicle are obstructed. The radar is usually hidden below the grille or in the rear bumper area, serving the intelligent driving assistance systems like adaptive cruise control or collision warning. If covered by mud, leaves, snow, or bird droppings, the radar can't detect objects ahead, triggering a warning and suspending some functions. I once encountered this issue after driving in the rain—inspecting revealed mud splatters on the grille, and gently wiping them off with a soft cloth made the warning light disappear. Now, after every car wash or long trip, I make it a habit to clean the radar area to prevent obstruction and ensure safe driving. If the alert persists after cleaning, it's advisable to visit a Honda dealership promptly to check for internal sensor faults. Remember, this feature is especially crucial on highways—don't overlook this small detail.
I also experienced radar obstruction while commuting in my 2021 CR-V. It felt like the car was alerting me that something was blocking the sensor. The radar is located at the front of the vehicle, primarily helping us avoid rear-end collisions or maintain distance. Once covered by dust or debris, it stops functioning. My approach is to find a safe spot to park, pop the hood, and check around the grille for any dirt. If present, I gently wipe it off with a clean cloth, avoiding harsh scrubbing to prevent radar damage. I did this after a heavy snowfall last time—it took just minutes for the system to recover. Regular driving awareness and extra cleaning after rainy days or off-road trips can prevent issues. If frequent alerts occur, it might indicate sensor aging or wiring problems, making professional inspection advisable. This minor incident reinforced the importance of regular maintenance for driving safety.
