I wouldn't say that my EX was unreliable, but I've definitely had better luck with my Hondas. Since I last posted on this thread, a number of issues started to pop up here and there.
1. Steering rack leak at 94K. My wife and I decided to get it replaced at the tune of around $2,100.
2. Throttle body at 94K. It just so happened to go bad when the car was getting the steering rack replaced at the dealership. Lucky for us, they decided to cover the repair on their dime. My estimate was about $900 for that fix.
3. Radiator at 115K. This wasn't too surprising, as others here have reported early failures with this part. I wouldn't call this an early failure though. I think my cost to fix was around $700-$750 at an independent shop. The dealership wanted $500 more (using the OEM radiator).
4. Wheel bearing at 132K. This is another part that's been reported to fail early on these cars. Again, I wouldn't call mine an early failure. I don't recall exactly how much this fix was, but I believe I paid $380 or so to the independent mechanic.
5. Water pump, and rough engine operation at 144K. This is where we decided to cut our ties with the car. The looming water pump replacement was creeping up towards $1,400. But my wife was more spooked by the rough running of the engine and did not feel it was safe for the family to ride in the car. So I "sacrificed" myself
to take the EX on it's final drive to the dealership to trade it in.
I'm not the type to purchase extended warranties for my cars; but in hindsight (of course) it definitely would have paid off to get something that covered this car to at least 100K. Even though we liked the car and how we were treated by Infiniti, it's unlikely that we'd get another. The lower reliability compared to our past cars, combined with our lack of interest in Infiniti's current lineup will keep us away for a while.
