Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I was traveling 60 MPH on a freeway when the car suddenly went left and then right. It felt like the car was steering its self. When the pitched it went into the left lane then the right lane. I was in the center lane. I was able to bring the car under control but it scared me. It was so dramatic I could have had a very nasty accident involving my death or the other drivers an the freeway..I took my foot off the accelerator and put the car into the slow lane and backed speed down to 50. The weather was not an issue.”
NHTSA complaint #10825512, filed 2016-02, 45,000 miles“My 2003 z06 Corvette battery keeps draining. I'm on my 3rd battery and the service dept does not know what's draining the battery. The problem is fixed when I receive a new battery, but in 6 months that battery begins to fail. If the car is not started within 3 days the battery tends to die. The dealership tells me to start the car every day, but I have 2 other cars (gmc's) that don't need to be started every day. This car is only 3 years old and I don't think it needs to be started every day. I believe something is wrong with the car and the service dept, can't figure it out.”
