The simple answer is that no, it’s not true. The biggest threat to AES encryption is poor choice of password.
AES is often confused with WEP which is easily crackable.
The more complicated answer is that nothing is 100% secure and anything is susceptible to attack. The most common security hole, which is not actually common, is a software bug that bypass the need to break the key. The key length and password chosen can help determine how likely it is to be cracked. Entry via brute force and dictionary attacks are different than the encryption method having flaws.
There is a theoretical weakness in AES but it has never been proven. Even if the weakness were proven, it would not reduce the time to crack it into a reasonable time-frame, IE less than the lifetime of the universe.
