## NHTSA's summary

Some 2020MY and newer vehicles equipped with a front view camera may illuminate certain warning lights and trigger DTC C272246 fault code for the front camera. In the following cases, the front camera auto\-calibration range may be exceeded while driving: • If the front camera is not properly installed and is completely or partially detached. • In case of excessive changes affecting the vehicle's balance \(e.g., loading excessively heavy cargo in a specific location of the vehicle, or significant under\-inflation of the tires\). • Specific road conditions affecting the vehicle's balance \(e.g., excessive road crown\) This TSB provides instructions on how to service the vehicle when the front camera related warning light\(s\) are triggered due to system out of calibration \(DTC\_C272246\).
