Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“The vehicles engine consumes oil during normal operation at an unacceptable rate. I need to add oil after every 300-500 miles! And I usually end of adding up to 3- 4 quarts of extra oil between oil changes. The level of consumption may differ from vehicle to vehicle but nevertheless, it is excessive. If I were not to do so, the engine would run out of all oil well before the recommended oil change interval and result in catastrophic failure. This problem requires me to pull over several times at the side of the road to add oil during normal operation. …”

“I bought my son a nissan Infiniti G35 s make 2007. When driving, all of a sudden he noticed battery light on, brake light on and power steering quit working. Turning the steer was extremely hard, much much harder than a nonpower steering. Fortunately he has strong hands and is used to driving an old nonpower steering vehicle, hence he was able to still drive it. Most elderly, or females would end up with an accident,when at high speed, they can not turn the steering wheel. Especially if it happens without any warning at high speed. I took it to dealer. …”

“Infiniti issued a notification that the radiator fan motor may become inoperable, which may cause the engine coolant temperature to rise. In this case the engine protection logic will limit the vehicle speed to prevent any damage to the engine. I contend that this is a safety issue. Should this failure occur, the car may be required to be driven many miles in traffic at a reduced speed. This in itself is a safety issue.”

“I have a 2007 Infiniti g35x sometimes when I am driving the car about 60 km/h and accelerate the car alarm comes up engine service soon and slip and vdc and it starts going crazy doesn't shift to the next gear and when I hit the brake it stops differently. It is hard to explain but scary it has less than 5000 km in. Also there is some noise too. The dealer ship try to find it now but I don't know about these guys. With the first thing with all the alarms. If I turn the engine off leave it for a minute and turn it back it resets the alarm but not the service engine one. …”
