Hi I have no clue as to how and why but when it began our Santa Fe was running fine and showed no signs of trouble. What would cause intermittent no starts/no crank, replace battery, no start/no crank now with a check engine mil. We take it to Hyundai Service dept who tells me they could not properly diagnose the no start with engine not running, perform compression/leak down tests with active codes 223 445 2106. Tow the car home find a blown fuse related to one set of codes P0445. I'm able to start the engine but have a loud tapping noise. Recheck compression and have 160 psi on all four. Test drive the car noise goes away after driving 1 mile up to 65 mph. Park it have two codes 223 and 2106. Next day start engine have hesitation in engine power and idle and a total of 11 codes. With the addition of the two codes mentioned my code reader showed 2009, 2110, 2119, and 365 twice. P2110 is also a code listed in a 2010 Hyundai Santa Fe 2.4 T.S.B that pertains to the ETC relearning set values. Take it back to dealer. Now we have active codes P0200A, P0222, P2106 and the Hyundai mechanic tells me they will need to replace the intake manifold and ETC body. How all of this came about but it's confusing to me why the check engine light did not come on from the moment the intermittent no start began? Old battery had good voltage at cold start and alternator was charging. The starter wasn't acting up either. The blown relay fuse was a sensor fuse for Injectors #1 - #4, canister close valve, canister purge control solenoid valve, oil control valve 1/2 exhaust/intake and variable intake manifold valve #1/2 The 5 year 60 warranty has expired and we are the 3rd owners the only warranty that still applies to the car is the 8/80 federal that only covers PCM, Catalaytic converter and 0BD2 device. The California emissions 7/70 does not apply because car has 71.000. My question to you sir is this WTF happened here? Is it possible to consider a computer malfunction because if there was a mechanical problem with air intake or the E T C why didn't ECM/PCM pick up on this?
