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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

problem #2

M45 4.5L V8

  • Automatic transmission
  • 110,000 miles


These V8 engines burn significant oil. Also if left for any time, when starting the engine sounds like a bag of nails (Ugly noise for a few seconds). This is creating engine wear.

M45 4.5L

  • 108,000 miles

Dealer tells us this is normal. Every time we get gas, I check the oil to see if its low and add oil. We've been doing this for years and Infiniti will do nothing to fix a defective engine. There are posts all over the internet about this problem in the 4.5l V-8. This wasn't a cheap car and the company should do something about it.
