Good luck even under 3 years. Our 21 Mojave with 3 K just sat at the dealer for 42 days waiting for a warranty battery. We finally went and bought a new better battery just to get our truck back. They told us they had no idea when they would get on as they are on nationwide back order.
The JT is still sitting at the dealer and still no battery's 4 weeks is unexceptionable!!! Lythia in Medford, Oregon is the dealer. Very bad service!!!
Well the hated battery failure got our 21 Mojave with 3000 miles on it this morning. and now a 2 week wait for the dealer to get the parts, They said both battery s failed. Good thing is we don't need it. we have 2 other rigs to drive.
