I loved my "Q" I hated my "Q" ! Transmission failure at 65,000 miles. Engine failure at 126,000 miles. Piston hit valve total engine loss. AC failed. Window lifts front doors failed. Sun roof motor, antenna motor, door lock driver side failed. Easily the most costly and unreliable car I have ever owned. No Nissans for me EVER!!!

I have loved this car ever since I bought it. It has a very power engine and is yet very comfy. If someone gets a 90-93 THEY HAVE TO REPLACE the chain guides for the timing chains. They are plastic from the factory and break. If the guides break the timing chain can flop around and the crankshaft or cam can jump a tooth resulting in piston to valve contact. The updated versions are metal backed and do not fail. This is a very big job for the D.I.Y'er. At the dealer expect to pay $3000 for the job. If you do it yourself the parts will cost $200 Once the chain guides are done with proper maintenance these cars can go to 300,000K easy! These cars are great and VERY reliable

Bought it used in 1996 at 41,000 miles along with 100,000 mile warrantee from Infiniti. They repalced transmission at 50,000 and essentially the entire A/C. After warrantee expired at 100K, I replaced one fuel injector, a belt idler pulley, an alternator, a suspension arm (front bushing), bellows (rubber) on the rack and pinion steering and of course brake pads and rotors as consumed.
