Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2003 Nissan Sentra Owner Comments

problem #2

Feb 212011

Sentra GXE 1.8L

  • Manual transmission
  • 67,108 miles


I had many problems with this car. In the first year, the engine starts and stops. Then I lost for no reason, a front cover of the engine. And now no heat, replace water pump and not sure if it's the head gasket or not. So far it will cost me $1500 for an used car (2003). When I bought this car, I thought I could keep it for a long period of time, like my old Tercel. Definitely not recommended, next car will be Toyota or Honda.

Sentra GXE 1.8L

  • Automatic transmission
  • 71,458 miles

Anyone who looses heat (blower working but no or little heat coming out) on a Nissan Sentra 2003 with a 1.8L engine PRAY that it turns out to be the thermostat or even a bad water ready to accept the fact that it's MOST LIKELY a blown head gasket and be prepared to "bail out" your local repair shop with a "stimulus package" worth over $1000, more like $1500 dependent on what other things they will find when they take your engine apart.

These things should not be happening to cars that are driven by regular folks (like me) to work and back (I don't street or drag race it). I'm not a mechanic, but I know a lot about cars, I've maintained and worked on them for 20 years...this is, as I'm finding out now...a design flaw in the Nissan 1.8L engine one that the media HYPE about Japanese car's reliability has been able to mask until now (thank you internet).

If there ever was/is a class action for this problem, COUNT ME IN :)
