Dear sir, I purchased a 2005 Nissan Altima ser with a 6 spd. Manual transmission approximately 14 months ago used with 33,000 mile and factory drivetrain warranty until 60,000 miles. My car currently has 59,000 miles. About two weeks ago, I brought my car to ira Nissan in woburn MA for a re-occurring clutch issue ; clutch pedal sinks to the floor making the car undrivable and grinding in the transmission shifting into third gear. Under warranty, Nissan replaced the transmission and clutch assembly. Last Monday, a week after getting my car back, the clutch is once again sinking to the floor just as before, and the Nissan dealer is saying because the can't replicate the problem, there is nothing more they can do, leaving me with a car that is unreliable and unsafe.the clutch fails intermittently and usually returns within an hour or so, making the car difficult at best to drive in traffic and making it hard to replicate on cue. The clutch appears to fail after an hour or so of driving or after it gets warm, with no warning. The dealer drove it for 7 mile and says it can't duplicate the issue.. Nissan customer service says they know nothing of the issue even though the internet lists over 60 incidents of clutch pedal sinks to floor on 02-06 Nissan with standard transmission, especially 05-06 Nissan ser"S.- but they have never heard of it" my case number with Nissan is 6600267. I use my car primarily for commuting gloucester to woburn and back and I typically don't have an issue, but it has happened 6 or seven time now and I know for a fact this wasn't mentioned in the sales brochure for this model Nissan. This is problemdangerous, as you can imagine being stuck in traffic and not being able to move. And not knowing when you can rely on your car, and when you can't" please assist me in making Nissan do the right thing and simply fix the car- they replaced the transmission, replaced the clutch and a week later, still under factory warranty won' T do it right.
