After owning the car for about 6 months, the engine had a ticking noise when it was first started up in the morning. After multiple times at the dealer's service center, they drained the oil pan and found metal shavings in it. The engine was replaced at 11,000 miles.
At 18,000 miles it was at the service dealer for road noise when braking. Service rep advised that the factory installed tires were cupped and needed replaced, and he eluded to the fact that it was a recurrent problem and told us we should "put a good set of Michelin's on it." When calling 1-800-Nissan, they assumed no responsibility, so we replaced the tires at our own expense. Service rep also suggested front end alignment which was another $60 out of our pocket, although there was no misalignment found. Now with 12,000 miles on the new tires, and after following the manufacturer's tire rotation schedule, they're cupped again. Still Nissan does not admit there is a problem with their suspension system.
The temperature gauge would sometimes stick, but when you tapped on the dash, it would come up. The service rep could not duplicate the problem and would not replace it. After multiple complaints, they finally ordered a new gauge, but it took 6 months or longer for the replacement part to come in.
Cupping wear on tires is usually caused by wheel imbalance or worn steering or suspension components. If I was the service adviser I wouldn't have told you to get a wheel alignment done because that doesn't have anything to do with cupping. Get your wheels checked to see if they're balanced.
