I have a 2016 Nissan Altima. First: I was involved in an accident in which a regular truck hauling an enclosed trailer drove over a large piece of plywood on the interstate at 70mph in front of me (also going about 70 mph) causing the piece of plywood to raise off of the road after he cleared it and it flew into the front of my vehicle and bounced up onto the hood and then hit the roof before flying off of my car. During this process, pieces of the plywood became stuck in the grill area of my car. There were no injuries, thankfully, but I am concerned the airbags did not deploy. Second: I've had this car since July of 2019. Over the past 6 months I have noticed that when I press the gas, the rpms rise but the transmission takes a bit to shift into gear causing a lag in acceleration. I have also noticed that if I am at a light or a stop and shift into drive sport, it doesn't do this. I have gotten in the habit of shifting into the sport mode when accelerating from a stop sign or red light. Third: my daughter was hit today by a truck crossing lanes to turn in front of her. She was traveling at appx 35 mph. The truck hit my passenger side front area, destroying my headlight, bumper, and grill. It was hit hard and the airbags did not deploy. The seatbelt did not lock, causing her to bounce forward and smack her head on the steering wheel. I am concerned now about the seatbelts and airbags and am more worried that they are defective after reading other complaints about these same issues. I love my car, but it doesn't seem to be very safe at all.
