Loud rattling noise from engine upon starting the vehicle; had Cr-v towed to lia Honda in enfield, CT; lia said either engine fire or misfired spark plug - couldn't tell for sure, but that it shouldn't have happened and that I did nothing to cause it; machine shop is investigating to determine if cylinder head, which was melted, can be repaired, or if replacement is needed; checking for additional engine damage; investigation by lia is underway - so unsure how this will end.
