Most recent owner complaints, unedited.
Driveshaft broke while driving down the road!!
I received a check engine light will driving which is now indicated as code P0720 and P0500. The car refused to shift past 3rd gear and began to sputter and would not allow me to go past 25mph disrupting the flow of traffic.
Front and middle crossmember rusted out to the point they have no more structural effects issues discovered while fixing a know issue to these models : rusted out and leaking engine and transmission oils pans I had confirmation from the dealership and other independent repair shop that leaking oils pans are common for those models and can cause engine and transmission failure. For the crossmembers they are important structural components that directly affect suspension/direction and drivetrain secureness. If the plastic shrouds/cover are not taken off during inspection those issues will goes undetected until one of them reaches failure
The transmission Valve Assembly Control Module and Vehicle Speed Sensors have both failed. The car will not shift out of 2nd gear and cannot go faster than 40 mph. This is a safety issue. I had my car inspected by a certified mechanic and he diagnosed the problem. He also stated that that he has seen this a lot with Infinitis. I have maintained my car well but this is Not a maintenance issue. There are thousands of infiniti owners online stating that they had the exact same problem. I filed a case with Infiniti #52260861. This is a design flaw with All Infiniti cars and SUV's and it should be a Recall or at a minimum fixed for free by Infiniti. It cost me $3,500 to have my car fixed and this should be paid by Infiniti to me and all other Infiniti owners with this same problem.
Driving car normally and car randomly put itself in 3rd gear and slammed down hard almost making me cause a crash and injury to me. Went to dealership they told me I need a new transmission due to valve body that they don’t sell by itself. This is the second time a replacement was done and it happened
Valve body failure
Transmission valve body has failed 2 times in less than 4 years of ownership
Valve body went out at 90k miles . This is way common and i took care of the car.
Received PO270 code which is speed output sensor which requires valve body and TCM to be replaced. Dealership stated that there should be recall but is not. Very common issue and Infiniti would not provide any help.
