I've owned a Silverado, Monte Carlo, Camaro, also a Escort (wife), and now i bought a 2001Sentra, I do all my own wrenching/maintenance. I bought the sentra thinking that Nissan had finally stepped up to the plate for quality and reliability, Nope, that Professional Grade stuff is just marketing hype.
That @#%&%! thing started falling apart @ 50,000 mi. when the AC compressor teflon seals went and since then the transmission has eaten its young when the TCC solenoid failed and the sun reaction shell cracked at the spin weld, the engine intake manifold gasket leaked, the wiper control board failed, the rear axles seals failed and ruined the rear brakes in the process, the exhaust system cracked in two and fell off, the brake vacuum booster unit failed, the front ball joints needed to be replaced because the rubber grease bladder rotted and split open, it was recalled because the electric rear-view mirror switch would short out and set the driver's door on fire, it eats brake pads every 25k mi. (and doesn't stop very good when the brakes are OK), the drivers seat rocks back and forth because a small internal piece breaks and I've had to replace the oil lines twice and now the third set are starting to leak at the couplings.
I will never buy a nissan again
from now on it's only Chevy and Ford
