“The engine. The coolant low light stays on even though it isn't.. Have had it checked. They said its all ok. Then I read these complaints. Why aren't they being held responsible for a defect!!!!! Its their defect, not ours. We didn't sign up for $1200 in repairs or more!!! Are you getting paid to sit there and just put these up here to appease us? No wonder this nation is going you know where in a basket. Lack of integrity. My brakes also both went out completely when someone gave me less than a foot to stop when they pulled out of a parking spot downtown. …”
NHTSA complaint #10733492, filed 2015-07, 199,000 miles“I was driving in town when a car pulled out of a parking spot right in front of me giving me two feet to stop at 25 MPH. I stopped but my brakes blew. Total failure of two brakes. The engine. According to your complaints I might have a gasket to replace because I have a coolant light on and it doesn't need any. The repairman said I needed a new sensor. Hmmm. Electrical. Fuel gauge is inoperable. Coolant light wrong. Airbag lights can't make up their mind if they work or not. The car locks me out repeatedly. The power windows won't work..dangerous here with all the rivers and waterways. …”
