NHTSA lists 1 safety recall and 9 owner complaints for the 2015 Infiniti QX70. Most complaints involve service brakes (3) and power train (1). The EPA rates it 18–19 mpg combined.
Nissan North America, Inc. (Nissan) is recalling certain model year 2012-2014 Nissan Juke, 2012-2013 Infiniti M56, QX56, and 2014-2015 Infiniti Q70 (V8 engine vehicles only), and QX80 vehicles. The fuel pressure sensors may not have been sufficiently tightened during production. As a result, the fuel pressure sensor may loosen with vehicle usage and cause a fuel leak.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“Brake fluid began leaking onto the ABS actuator circuit board and created an electrical fire. This melted the engine harness and the connector to the abs module. This was confirmed by dealership technicians at Sewell Infiniti - Dallas. Dealership informed me they could not fix the vehicle because the part needed to replace (affected by a different recall), was discontinued and made me tow the vehicle to my house. The issue was confirmed by mechanics at Parkwood collision - Frisco. InfinitiUSA customer service acknowledged the issue and that they would have the original supplier of the engine harness (discontinued) make me one if I purchased at the dealership (which to my understanding would not solve the original issue at hand). It is available to inspect upon request. I have pictures and videos. The fire did put myself and others at risk as the engine harness was melting and shorting out while pulling my vehicle to the side of the road. It has not been inspected by insurance rep; at this time. There were zero issues with the vehicle or modifications to vehicle at the time of the incident. There were no warning lamps or symptoms until it was too late.”
“I was driving down the highway and the revs went up really high with some banging and clanging, the check engine light came on and the gears stopped shifting. The dealer told me the transmission valve body failed and it seems to be a common issue in these cars. Not safe to drive as the gears wont shift and this seems to be a sensor in the transmission that is doomed to fail after a matter of time. Infiniti reengineered this part because they know it is going to fail but have not issued a recall.”
Towing, payload and dimensions aren’t in the EPA or NHTSA data, so we don’t list them.
