101060 mi

C $210
Compressor is noisy. After the radiator leak/replacement in December, we didn't recharge the AC... with the super cold weather it would be hard to get reliable gauge readings (our shop is quite cold). The evacuation for moisture and recharge with the gauges went well,.. Temp. dropped from 22°C to 8°C. But the compressor is a little noisy. Found it difficult to determine how much AC Compressor oil was in the system (wonder if the little cotton analyzers are accurate?). I suspect it needs more oil. I'll update the result. 
159960 mi

C $288
Weak cranking and it wasn't cold out. Sometimes OK, sometimes NOTHING. Replaced older battery. Charging voltage 13.69v. Checked ground wires. Checked for corroded or shorted out main starter cable from battery. HAD to be the starter. Reports on refurbished starters were awful... often lasting only 1-2 years. New starters were stupidly expensive for Infiniti. So... found a replacement used starter at the local auto wrecker for $150 on a car that had only 80K on it. (Hey... if my original one lasted until 257K then this used one likely have plenty of life left.). Gave myself a Xmas gift and got my mechanic to simply put in IN... no diagnosis etc. JUST labour time. 1hour. $138. I now LOVE the enthusiastic cranking each time I start up my Black Beauty! 
184760 mi

C $240
Fuel Gauge Malfunction. Changed a computer module on top of the radio that controls LOTS of things like the AC/Heat system, airbags, locks, remote etc. The sensors in the gas tank were good. The "self-check" of the instrument panel passed. followed the wiring from gas tank to that white module with 3 (?) plugs with multiple wires on top of the radio. Relatively easy access... but was really hard and unbelievable to diagnose !
