Rendezvous — U-body / GMT257 (2002–2007)

2004–2006 Factory-verified

The 2004 list prints it without "6 cylinder" and "GM"; the 2005 list prints the wording of LA1 (6 cylinder, 3.4L, multiport fuel injection, high output) for this code, which reads as a copy error because the 3.6 L is the LY7 in 2004 and 2006 (Wikipedia: 3.6 L V6 on the CXL). Not printed in 2007.
