NHTSA Complaint #11548137 — 2017 NISSAN MAXIMA

Car starts, but would not accelerate. Turned the car off, started 10 minutes later, car would not accelerate past 5 mph. Drove a 1/4 block turned around, car’s power steering locked up in drive way. 12 hours later car works fine, no acceleration issues. Brought to Nissan dealership, they found no issues. 2 weeks later, drove for 3-hour trip. Returned home and parked. Started car 30 minutes later, drove 10 minutes and car loses acceleration again in the middle of road/traffic. Able to park safely. Car engine would not restart, lights and hazards working. Error message on dash says incorrect key code. Called a tow, they jumped the car with a jumper pack and engine starts, car accelerates. 1 day later new battery installed, new battery in key fobs. Car is accelerating and starting now. My complaint, my belief that there is a serious design flaw with the keyless start option. Car is not detecting key while in drive every time. No indication given that batteries were low power. Safety issues - no detectable problems found by mechanics, losing acceleration while in traffic possibly due to key fob malfunction. Why is there no option for traditional key start? How can car be trusted to start/ accelerate when driving long distances, when there is no reasonable explanation for the loss of acceleration? This is not a unique issue, a number of complaints online for viewing. Videos on how to ‘fix’ by unplugging car battery. Consumers should not have to diy/disconnect car battery just to start a car.I believe this is a deeper issue with car design and is a safety issue for teen and adult drivers.
