2012 Infiniti FX35Engine & cooling

This engine uses a metal timing chain inside the engine. Infinit chose to use plastic guides and tensors to keep the chain in place and not wear stretch. This choice of PLASTIC results in the eventual failure of the components that are needed to keep the chain in place. First signs of impending failure is a rattle inside the engine. Eventual the chain will break loose and destroy the engine. The parts themselves can be purchased at any auto parts store for under $50.00, however labor is in the thousands or...

engine complete failure. A simple search of the internet will show that nearly all owners experience this. Most opting to sell the vehicle or chance failure does not occur. My mechanic has confirmed and I will go to an Infiniti dealer if need be.

2012 Infiniti FX35Engine & cooling

I was driving through an intersection at about 15/20 miles an hour as the light had just turned green & my car just shut down out of no where all the lights were on on the dash, and the car rolled to a stop. I turned the emergency lights on. I put the car in park and hit the start button again & the car started with no issues. This is the 3rd time it has happen the same way. Luckily the other 2 times I was driving through a parking lot and the vehicle just shuts down while accelerating & in drive mode. There are no warning lights on my vehicle for maintenance. Reading about this online it apparently happens a lot & to some people on the highway going 70 mph. This could be very dangerous!

2003 Infiniti FX35Engine & cooling

Purchased a new 2003 infiniti fx35 which currently has 238,000 and properly maintained with the dealer recommended maintenance schedule. At 234,634 and frequently thereafter the vehicle when driving would just suddenly overheat and engine cooling system malfunction causing automobile to suddenly lose power and start to shut down while driving on major highways or roads. This is a very serious safety hazard and dangerous on highway when you driving at 65 mph. Very, very scary and just barely avoided several rear end collision. I am still trying to get the vehicle fixed and would like for this complaint to be recorded as with all the other listed fx35 complaints. *Tr

2003 Infiniti FX35Engine & cooling

I have an '03 infiniti fx35 with 90,000 miles. I'm not an abusive nor negligent operator and have had all my services well maintained. Car began by overheating 15 hours into my 16 hour drive home from yellowstone this summer. It started overheating when I slowed down in towns and such...Replaced my thermostat....Flushed everything....Drove for quite a few weeks more with no problems...Thought it was solved :/ not quite. Overheating began once again...This time I had my heater going and noticed it going cold then...

within minutes my temp began rising. I pulled right over knowing what damages can be incurred. I had coolant being expelled from my spare reservoir just like the other instances. I waited for it to cool, filled it with water/coolant and made it a ways further, then repeat, repeat. Took my car to infiniti of beaverton who told me that my issue was a cracked radiator. They wanted 900 for it. Replaced it, car still overheated. Replaced water pump. Still overheated. Had my car towed back to infiniti who failed to have a loaner available (even though I called a day in advance and they said they would). They made me rent a car! They told me they still couldn't diagnose it and that I had to drive or have it towed to a different shop and pay to have a 4 gas hydrocarbon test done. Well sure enough a one-way pinhole leak in the head gasket not displaying your typical traits of gasket blowouts...Only a slight rise in hydrocarbons, but enough to show it had a leak allowing air into the system which then overpressurizes my coolant system causing the spare res. To be my release location. Once air is introduced and replaces the coolant an air bubble develops and system overheats. What I am getting at is that infiniti is not recognizing this as any problem. I have been going through infiniti consumer affairs who told me they could not help me at this time but with a $300 credit towards the $7000 engine replacement they want to perform. I'm disappointed with infiniti. *Cn

highway when you driving at 65 mph. Very, very scary and just barely avoided several rear end collision. For the price of the automobile brand new, with barely over 100,000 miles and the dealer unable to determine or fix the problem is beyond comprehension and extremely dangerous. The dealer suggested I pay them $ 10,000 to install a new engine--that is beyond comprehension. This problem is an extreme safety hazard and needs investigation. The last occurrence was approximately 11/9/2008. I will not drive the car for fear of a fatal rear end collision. *Tr
