AI Safety Analysis for the 2018 Nissan Altima

The 2018 Nissan Altima presents a mixed safety picture. While it boasts excellent crash test performance with 5-star ratings in Overall, Frontal, and Side crash tests, and a 4-star Rollover rating from NHTSA, its complaint data reveals several recurring issues. With 217 total complaints, 11 crashes, 0 fires, and 6 injuries reported, there are areas of concern. The most frequent complaints are related to 'UNKNOWN OR OTHER' (36 complaints), 'AIR BAGS' (23 complaints), and 'POWER TRAIN' (15 complaints), with 'SERVICE BRAKES' and 'ELECTRICAL SYSTEM' also notable. The high number of airbag-related complaints, despite a recall for a different airbag issue in earlier models, suggests potential ongoing sensor or wiring problems. The two recalls address a critical hood latch corrosion issue that could lead to the hood opening while driving, and a backup camera display malfunction, both of which directly impact safety. The hood latch recall is particularly concerning given a reported incident where the hood unlatched and cracked the windshield.
