- 2011 LaCrosse CXS
My daughter drove our 2011 LaCrosse CXS with only 95k miles in 1st gear at redline (she couldn't understand why it was so loud and wouldn't go faster than 40 mph) until the engine gave out catastrophically. So I am looking for a replacement engine. It seems the 3.6L LLT that this car comes with is so much more expensive ($2.5k+) than other newer 3.6L engines like the LFX. Are there any other engines that will work? Thanks in advance for helping a new forum member!
