Catalytic converter broke down and particals caused internal wear to the motor. That causes the motor to burn oil.

Like many others my 2003 Nissan Altima has stalled in traffic while driving. It reads no codes. There could have been a serious accident! this is a major concern I could have been on the interstate or in having traffic. I called Nissan and they state there was a recall for a problem to this affect and it was already fixed on this vehicle in 2007. They will not fix it again. Unbelieveable! also like many other my floor board has rusted. I had a patch repair to pass inspection. This car is a saftey hazord. After reading numerous reports that others have experienced similar situations of cutting off in traffic! I have not read any fatalities yet thank goodness! recall this car befor someone is killed!

Whie driving about 45mph the engine shuts off, steering was very hard. Tried too restart engine, hard to restart. At tiomes the car is hard to start after sitting for awhile. Engine also stumbles, or seems to miss fire while driving. This not the first incident. Had the sensors replaced after the first problem.

This Nissan is burning oil like crazy. It started in Jan, 2015, engine was making terrible noise, oil level checked, completely empty. I took it to Nissan who said it wasn't a problem and did oil change. Then, just this Saturday, June 27th the car was hard to start and sounded like metal so I turned it off and checked the oil- completely empty again. We had to pour 4 quarts in!!! it does not have a leak, nothing is ever seen where it has been parked. It is just burning oil like crazy due to some type of defect from Nissan that hundreds and hundreds have complained about on line if you google Nissan burning oil... and dangerous situations that have occurred. I do not want to wait for an accident, please, please, listen to all of us and get Nissan to address this failure with their vehicles. This vehicle only has 100,000 on it and I have changed the oil every 3500 miles without fail. I did nothing to cause this along with the other hundreds to thousands of other Nissan owners that have complained about this. I have called Nissan in the past on my other Altima about their ac that fails due to it always running with defroster and it doesn't turn off then so it's always running. Also, I see many other rusted out floorboards, causing the passenger seat to not be bolted down in this same year that I had happen to me 2 years ago and had to spend $2000 to fix that they said the same, sorry, this is not our problem. What would have happened in an accident, the passenger would've not been protected when their seat flew off. Please, please go after them....they are terrible.

Engine oil excessively being consumed/burning. Exhaust leakage. There is a recall that addresses this (NHTSA campaign number: 03V084000 ) and it covers my model year, but it would not come up on the dealer's computer so they did not fix the issue.

Car began to idle roughly and was hard to start. Replaced oxygen sensors which did not cure symptoms. Was told that the 2 pre-cats (catalytic converters) needed replaced. Motor mounts also recommended. Replaced and problem persisted. Hard to start, runs rough now shutting down while driving. Ran codes myself with obd-II tool and found crankshaft and camshaft position sensors to be faulty. I heard of a recall for this very issue; even described my symptoms exactly. Even though my year model and car was recalled the Nissan of fort worth service desk told me my VIN # was not covered. My car has the exact same engine as all of the other Nissan made in this year range and the same faulty crankshaft and camshaft sensors but for some unknown reason mine are not covered by this. How is this even possible. I have replaced a lot of pricey parts all which may have been avoided by replacing the sensors. Even if I had to pay for the crank and camshaft sensors it would not have been bad if I had not paid over $3000 in repairs to other stuff that may not have needed replacing.

In the past 2.5 years I've had to replace 2 coils on 2 different cylinders, and 2 different crankshaft position sensors as well. Each time it's cost me upwards of $300 each incident. A review of the internet website for complaints from Nissan drivers of the same vehicle make/model/year indicates that others have also run into these issues without any recompense. Some even had their cars stalling out while driving, which is obviously a safety concern. "luckily" (and note that I use the term in quotes), my experience has been that the engine starts running rough, feeling like on just 3 of its 4 cylinders, then the "service engine soon" light comes on. It was then always obvious something was really wrong. Q: why wasn't this a recall item for the Nissan engine? P.S. I have less than 60K miles on my car and it's in pristine condition and always garaged.

2.5L engine S model Nissan Altima. 2002-2003 has well documented blogs and complaints of excessive oil use. Causes are any thing to poor design valve seals to dust kick back from overheated catalytic convertor into piston/cylinder area causeing ring failures as well. This current vehicle has to been diagnoisised by a Nissan dealer. It burns 2 quarts of oil per 160miles. The dealer recommends a new engine and new catalytic convertor. The regional Nissan manager chris states Nissan will not assist in any way to replace/repair these items because we have not owned the vehicle long enough. The car is worth $3800. The engine +convertor+ labor is over the value of the car. Some one high up somewhere dropped the royal ball on recalling this engine.

Car stalled two times within 20 minutes when slowing car down to make a turn. Meineke and paul miller Nissan of fairfield, ct identified that parts 23731-al61A (crankshaft/camshaft sensor) and 23731-6J90B (camshaft position sensor) need to be replaced. These sensors were part a recall for the same make, year and model of car that I own. Nissan N.a. claims that my VIN was not a part of the recall. 630,000+ vehicles were affected by this recall but my vehicle does not apply. On line complaints suggests that the exact same complaint keeps recurring but Nissan has not expanded there VIN registry to include all cars that are affected. Spoke with Nissan N.a. case expediter who stated my vehicle VIN was not on the affected list although my complaint was the same as those vehicles on the list. Nissan representative would not tell me where my part was made and where the defective parts were in fact made. Claimed that this was internal Nissan information that they had no obligation to give me.

We purchased the vehicle from a private individual. It had 105000 miles on the odometer, it is a 2003 Nissan Altima with a 2.5L (4 cylinder engine) shortly after purchase.. we noticed a very foul smell coming from the exhaust and into the passenger cabin. Also the engine consumed 1 quart of oil per 50 to 60 miles. No exaggeration ! I discovered a recall on the Altima concerning it's precat/catalytic converter could over heat, break into pieces and some of the pieces could be sucked back into the engine, scoring the cyclinder walls and causing excessive oil consumption. I emailed Nissan with my concerns. They assigned a case # to my concern. They asked for a Nissan dealer to evaluate the problems and give them a formal diagnostic of the issues. The Altima had a new catalytic converter installed in 2007. A oil consumption test was done on the car and the oil topped off and we were told to come back in 250miles so they could check the oil. In 160miles we returned and there was no oil on the dip stick! also the check engine light was on and a code for "catalyst" problems was in the computer. This was all sent to Nissan via email. Now instead of a rep. Handling the issues.. they have sent it to a regional rep. And we are awaiting their "goodwill" decision. That year Altima and engine has repeat issues even after recall repair. Tpart of the recall states that if the owner does not check the oil often and ignores engine noises that it could result in a fire! supposedly a exhaust hanger catchs debris and causes the fire"?? lol who are they kidding"

Malfunction indicator light is on. Drove to a repair shop to get a diagnostic analysis on the engine. I was told the reason for the indicator light was because I had a bad crank sensor. There is a recall for that so, I called the dealership and they ran my VIN number and told me there was no recall for my car and I explained the situation to him they still wasn't going to fix it. Then I called the Nissan recall place and she said the same thing. So now what do I suppose to do now.
