One Kowloon Motor Bus-owned Centroliner (fleet number AP69) was forced off a viaduct by a lorry on Tuen Mun Road on 10 July 2003 and was subsequently written off. All of them have been put back into the fleet. However, the actual reason is not clearly known. Some believe that it is caused by the difficulty in maintenance by NWFB, or due to the fleet quota limit set by the Transport Department of Hong Kong. Since 2004, a number of these buses have been suspended from service. They were delivered in 2000 and entered service in 2000/2001.

Two of them (fleet number AP144, AP159) are the world's first two citybuses to be equipped with six-speed automatic transmission.

They (AP21-AP130) were allocated to long-distance routes serving North/ Yuen Long/ Tuen Mun Districts. In 2000, KMB received 60 Centroliner N4426/3s, followed by 50 similar buses in 2000/2001.
