Failure Date: 02/21/2010

This is pertaining to an existing campaign (#03v084000). I bought a used 2002 Nissan Sentra ser spec-v in may 2007. Shortly after my purchase (June 2007), I had this outstanding recall, including several others performed. The above recall states that the pre-catalyst could overheat and disintegrate, blowing particulate into the combustion chamber, scoring the cylinder walls, and cause excessive oil consumption and possible engine damage, requiring engine replacement. There was approx. 65,000 miles on the car at this point. Last February, I was driving along the highway when I suddenly lost power. I pulled over to the side of the road and found the engine would barely run and would not rev over 2000 rpm. I had this car towed 20 miles to my local Nissan dealership. Upon inspecting the vehicle they told me that the pre-catalyst that I had already had replaced on the recall, had disintegrated, plugging my exhaust, blowing chunks of debris into my engine, therefore destroying the engine. I was told I'd need to replace the entire engine at a cost of $4300. 00. This car only had another 50,000 miles on it after the initial recall work was done. Since what happened to this vehicle was exactly what the original recall was supposed to prevent, I went to Nissan, requesting that they stand behind this obvious design defect and at the very least assist me in replacing this engine. I was given several different stories ranging from accusation that I did not maintain this vehicle (even though I do so religiously at Nissan dealerships) to stating the dealer I had the work performed at was at fault and I should pursue restitution from them, to the fact the car was no longer under warranty and I was sol and this was 'normal' wear and tear. Now, I can understand normal wear and tear but no catalytic converter should be designed so that it will destroy an engine if it fails and this was supposedly addressed in the above campaign.

Failure Date: 01/12/2010

Bought Nissan brand new in 2002. This car is only 8 years old with 75,000 miles. First the car started jerking when it sits still at stop signs and traffic lights. Took the car to maintenance shop and paid to have the catalytic converter removed and replaced. However, after a few months, in April the car starts jerking again. Paid to have the ignition coils replaced by the dealership. Car engine light still on and car still jerking. Contacted Nissan corporation and was told that the car was not under recall. Now the dealership replaces the egr valve and 02 sensor. Car engine light still on and car still jerking as if possessed as of August 20, 2010. Money, money and more money.

Failure Date: 11/09/2009

I own a 2003 Nissan Sentra se-r spec v and while driving the engine shut off which could of caused me an accident and it restarted but didn't want to pickup speed. Had to get towed off the freeway and now does not want to restart. I had my daughter with me, which was very dangerous. Called Nissan and they said my car is not on the recall list, even though there is a recall for this year and model. Several mechanics told me that I need the engine replace, which is very expensive to which I cannot afford and my car is just sitting there.

Failure Date: 10/28/2008

In my 2004 Nissan Sentra se-r spec v with a 2. 5l engine/manual transmission, at about 69k miles the car suddenly experienced unstable engine idling and significant power loss. First mechanic found loose metal pieces in the intake manifold area, along with spark plug one fouled. Metal pieces were removed and a new spark plug was installed. Car ran okay for a few weeks, the same symptoms occurred. Mechanic removed intake manifold and found two power valves and their screws obliterated and scattered throughout the compartment in dozens of loose pieces. Metal pieces removed, power valves replaced, screws replaced and secured with lock-tite. Symptoms occurred for a third time recently. I went to the Nissan dealership and spoke to the service advisors; they ran the VIN and found a recall on 04 Sentra 2. 5l engine vehicles, specifically the power valve screws coming loose, causing unstable engine idling and power loss.

Failure Date: 09/15/2008

Was told by Nissan that my 2003 Sentra se r spec v need a new engine. Engine failed because of defective catalytic material being ingested through exhaust valves. Thus scoring the cylinder walls, leading the car to consume oil. Without oil the engine will fail. The car was brought to the dealer concerning an oil consumption problem, dealer declared that it was within parameters and there was no problem. This was just before the 60,000 mile warranty was up. The car now has 95,000 and needs new engine. Nissan claims to know nothing of this problem, yet there are thousands of people with similar problems.

On several occasions my 2003 Sentra ser would not start. . . . On three occasions I replaced the battery and it would restart . . . On the 4th occasion I took the car to Nissan dealer here in harvey , la. Where it sat for 3 days and the service dept told me the car would now start. A fifth occasion occurred and by this time I had heard of a recall which I asked the dealer on phone about and he told me to bring car in so again I took car to dealer hoping to find problem. . . Car sat there again for a few days after which it would start. They again told me no fault found was found and that they had performed recall. . . Which they did not . . . It took me a couple of calls to service writer before he admitted it had not been touched. I read here of many Sentra s with same problems . . . You would think some one would know what is going on. My Sentra now runs terrible sometimes not starting and other times runs like it is running on 2 cylinders with a bad smell from exhaust. I am afraid of this car , but cannot afford to replace it.

I bought a 2002 Nissan Sentra se-r with approximately 70k miles on it. At the time of purchase the engine was running fine, however, at approximately 72k miles it started burning oil and I had to put oil in the engine once a week. I took the car to the local dealership were they replaced the catalytic converted due to a recall, but did not state that the engine was damaged to that defective part. I asked about an engine recall but never received an answer from them as they said the car was not under warranty and had no warrants under recall.

Failure Date: 12/21/2004

Concern: engine lost almost all of its power. The head was cracked, and the #4 cylinder was missing one of the 2 compression rings. Car was in shop for over 40 days. Correction: waited 30 days for parts, entire engine, exhaust system, and intake were replaced. Car still runs horrible, and now the transmission does not like to shift when it is cold. The car over heated and possibly causing a fire.

Failure Date: 09/10/2004

This vehicle is equipped with California emission exhaust, and the problem is the front bracket that suspends the exhaust between the manifold and the rear bracket had rusted and fallen off. There was no particular event that caused this to happen and we learned of the problem be the knocking sound made by the exhaust pipe hitting a bar on the body when driving over bumps as small as 3 inches. The vehicle had been driven around 24,000 miles, and the quote for a replacement part was $217 plus labor and taxes. There are to date no aftermarket alternatives, and the way the bracket is attached to the exhaust is an inferior design that will ensure premature failure.

Failure Date: 02/15/2003

I haven't had the car for a year yet and I have already had the catalytic converter replaced twice & the engine replaced because there was no oil in it. What kind of car has these kind of problems? the gears shift hard now to where it about jerks you and I drive an automatic. Not to mention the dealership wouldn't even give me a rental while they had to practically replace the entire engine.

Failure Date: 04/15/2002

My engine failed again while driving 70 mphs on the freeway, the very day after the car had been repaired for yet another defect sensor. It was a miracle I did not crash and kill anyone including myself. Each and every time I have taken the car in, I have requested it be checked for a short in the wiring. Each time I was told no. I later learned thar meant if it didn't show up on the computer, then they wouldn't look for it specifically. Following the latest hazard, I got in Nissan's face. Nissan found a defect oxygen sensor this time. Upon retesting the vehicle, the emc (the brain of the vehicle) was found to be defective. I was also told had I driven the car any longer, the air conditioning unit would have blown too. Well, that explains all the lousy gas mileage this past year. So, here it is a week later and my vehicle remains in the shop with a back ordered emc with no available stock date in sight. I am renting a vehicle and am receiving very little assistance from Nissan as to getting a rental vehicle in the meantime. I am quite concerned I have purchased a brand new spanking yellow lemon. I am quite concerned this vehicle, even with a new emc, will produce other defective sensors once the warranty has expired due to wear and tear from the old one. There are 45 sensors in the vehicle and only 5-10 have blown so far. I am quite certain others are close to failure too. I am just as concerned when both the Nissan representative and the service manager told me this part has been on back order for a very long time as so many vehicles have endured this problme, that the vehicle has not yet been recalled.
