“Airbag light suddenly began flashing. I took truck to dealer and they said driver side airbag module shorted internally. Price to fix is $1,600.00. This truck has never been in an accident or at any time had its airbags deployed. All service to truck has been with Infiniti dealerships. Service representative said electronic issue and not owner error. This could happen at any time with this truck. I called customer service and they said problem is covered if truck less than 4 years old or 60,000 miles. …”

“During normal operation of the vehicle and while in motion, the ABS brake light indicator on the dash control panel illuminates when applying the brakes, which cause the brakes to shake and make scraping sound. At that point the brakes fail to stop the vehicle in a safe distance, increasing the chance of a collision. Abs brake light clears and normal brake functions return when the ignition is turned off, then back on.”

NHTSA complaint #10790004, filed 2015-11, 131,000 miles

“Brake light comes on while driving, when pressure is applied to brakes under 40mph there is a grinding noise and the brakes skip. You can turn the ignition off and back on and sometimes the brake light goes off and everything is fine and sometimes it is not. There seems to be no rhyme or reason. Some days it never comes on and some days it never goes off. After researching online it appears that it is an issue with the computer module and a software update is needed. Please fix this. The first time it happened it was very scary! …”
