2003 Q45 Oil Consumption, Defec Brakes

I purchased the Q45 in March 2003 and have 16k miles on it now. It has always been service by Infiniti wihtin the manufacturer specs. When I picked up the car, the front rotors were warped...they cut them. This problem has persisted over the past three years and they simply cut the rotors. Secondly, the car burns over 1 quart of oil per 1000 miles. As everyone else has experienced, Infiniti denies there is a problem, states that burning 1 quart per 1000 miles is normal. If you persist, they will then go through the "consumption test" and will try everything they can EXCEPT FIX THE PROBLEM. It borders on criminal to sell someone a $60K car with these problems and not fix the car.

I've had this car for 3 weeks now, and I've gotten so many looks on the street! No one really knows what it is yet and that's what makes it even more fun!! The engine is really quiet even when you push it hard, and if you're not used to this kind of power, whiplashes won't be scarce events. The interior is beautiful, and it offers so much more than the BMW''s and Benz's and Lexus's of the same price range. As for fuel economy, my previous car was a 1982 Buick Electra V8, so the M45 sipps gas compared to that. Not saying it has great fuel economy, but I just don't think it's that bad.

THIS IS AN AWESOME VALUE FOR THE $$$'S FOR THE SAME AMOUNT, YOU CAN WASTE YOUR HARD EARNED MONEY ON A 6 CLY. BMW 530 OR A 6CYL. LEXUS GS300. A VERY HIGH RECOMENDATION IF YOU WANT TO GET ANY OF THESE VEHICLES. ALL I HAVE TO SAY IS, 340 HORSES!!!! ANY QUESTIONS????

I bought the first M45 in Austin and smoked a Porsche Boxter the first week. I looked at the new E500 and there was no comparison, especially for the price. I've had three Corvettes and this one will definately keep pace with my 93 and seems to handle better, suprising for a large four door sedan. Looks best in Black with chrome wheels. Very 70's in style which I like but with far more technology. Though I've had mine now for two months, I've seen only one other one here. It appears this car will be another "sleeper." I'll have fun smoking other "so called" competitors: 540i, GS 430 and E 500.
