Coolant Leaking Problems of Nissan Altima

I had coolant service and after that I started experiencing low levels of coolant which led to overheating of car. I kept getting the car check to find out if there were leaks. I checked recall notices and then was told I needed sensors. I called Nissan in September and was told out of the 653k cars mine was not affected! I find that hard to believe. I then had sensors replaced (crankshaft and speed) . Now I'm being told head gasket blown and engine needs replacement. The recall from Nissan says there we engine cooling problems.

Went in for an oil change at mossy Nissan, kearny mesa, CA. Was informed the headgasket(s) were leaking coolant. Not covered under warranty although mechanic informed me the leak(s) were a common and pre-existing condition. He went on to explain that Nissan used the incorrect head gaskets for this model of 3. 5 v6 (front wheel drive vq35hr to be specific). Once Nissan realized their mistake, all subsequent engines received the correct head gaskets and the leakage problems went away. I am requesting that Nissan formally acknowledge the head gasket defect and extend the drivetrain warranty to cover the replacement expense. I am unsure whether the NHTSA can help me in this case, but perhaps if my complaint can be in the database, we can get more affected consumers to submit similar head gasket defect complaints in the hopes that Nissan will be forced to remedy the problem.

I believe that this engine defect caused the pre-catalyst to overheat and damaged the catalyst substrate. These particles entered the combustion chamber and probably scoured the cylinder walls prior to recall 03v-084 implementation. This resulted in increased oil consumption throughout the lifetime of the vehicle which in turn adversely affected the heater system not working properly, coolant reserves disappearing, engine started to heat-up, and ultimately engine seized-up. Prior to this I had to be adding engine oil and coolant every two to three weeks since engine would start to make noise and start to heat-up, but there was no leaks or engine light did not turn on. Previously, mechanics did not see any problems when taking it for oil changes and service. It is now at the dealership and they state that it will cost me $2100 to $5500 to fix this. I told Nissan service personnel that I found the same thing happening to many Nissan 2002 owners on the internet. I found several websites with hundreds of complaints just by goggling "2002 Nissan Altima oil consumption". Even Nissan service personnel told me that this is not normal since these vehicles should last over the 200 thousand miles, especially since we are the original owners and have always done routine oil changes and service. Please help me and the many owners of these Nissan Altimas who have trusted Nissan in building long lasting dependable vehicles.

I bought a 2002 Nissan Altima in November 2005. The last two years I have been having several problems concerning the vehicle including, jerking, stalling on highway, over heating and smoking. I have a the oc sensors replaced, spark plugs, Cadillac converts, coils. . . The list goes on and on. I noticed my oil light always coming on and the need to always refill the oil but I could not see where it was leaking from. The same problem was with the coolant---I kept pouring it in the place for coolant and in 2 days it would be gone. At the end of August my infant and I were in the vehicle and it began jerking and cut off right in the middle of the highway. A tow truck was called to pick up the car. I took the car to Nissan and they told me that the converter needs to be replaced again and the engine. After researching it looks as if this problem has been going on with several Nissan Altima's. I just want my engine and converter to be replaced the Nissan corp to take responsibility.

2002 Nissan Altima wouldn't start, blown head gasket, leaking coolant, now Nissan says I need a new motor. Aluminum was used making these cars and Nissan new they couldn't with stand the heat. My son needs help.

I loved the car until recently when I started having problems with the heater. Months ago, I noticed that my heater was not working properly. I took it to be looked at and the mechanic told me that there may be bubbles in the coolant line. They bled the line, refilled it and it was fine for awhile. I have no heat again. They checked and could find no external leaks. This has been a problem for the past year, and every few months I need my coolant replaced and bled. I've gone to numerous mechanics and nobody can find the leak. I've searched many sites and forums and this seems to be a recurring problem for my type of car. The engine is overheating because the coolant is leaking, the car idles rough and is driving w/ higher rpms than it used.

2002 Altima service engine light appeared and vehicle stalled. The vehicle's had been serviced several time by the dealer because the check engine light illuminated and the vehicle lacked power, jerked and would stall. It was later determined that the vehicle developed a cracked block which caused coolant to leak in the engine. The engine was replaced. The vehicle had been maintained regularly.

At about 80,000 miles my 2002 Nissan Altima had an issue where the coolant started leaking into to combustion chamber, had to have the heads resurfaced, and cat converters replaced. Now the car burns oil, has to be replaced at about 1000 miles (completely empty if I let it go to 1500 miles). The car now stops when driving at slow speeds, starts right back up, but dies while driving.

The contact owns a 2002 Nissan Altima. The air conditioning system will not circulate heat. Also after service the oil and antifreeze levels depletes prematurely. The vehicle was taken to the dealer, and she was advised that the catalytic converter and the engine coil needed to be replaced. A representative from the dealer and manufacturer stated that the repairs cost $1600. 00. No repairs were made. The failure mileage was 21. The mileage was 105,000. The consumer stated the vehicle would stall while driving at any speed. The consumer took the vehicle to the dealer and upon inspection, the consumer was informed a sensor was soaked in oil. There was no oil leaking from the vehicle, but they were not able to tell the consumer where the oil was coming from. Soon after, there was a recall for the same problem. The wheel bearing and alternator had to be replaced. The engine light has been on for over 2 1/2 years, the vehicle has no heat and anti-freeze was evaporating, but there were no leaks. The consumer stated she could smell coolant coming through the vents. Updated 02/01/jb.
