Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Was driving and suddenly, my vehicle started to lose power. Was very scary because it was at night. Engine light came on and power was lost. Pulled off freeway into gas station. Checked fluids, etc.. Upon trying to leave, vehicle was sputtering with no compression. I did not think I was going to make it home. After a few minutes, I tried again, this time giving vehicle more gas. It seemed to do a little better. But, every time I had to slow down or stop for a stop sign or traffic light, vehicle was sputtering and acting like it was going to stall out. …”

“If I left the engine idle more than two minutes it would not pass the state emissions test. Now the emission light came on and it will not go off anymore. Almost got an accident vehicle will not drive over 20 MPH anymore. I must have the same problems of thousands of other people. I was told I have to change the heads on the engine because of poor quality cast iron heads that was used for like three years. My Ford truck is one of these years they had the issues. Now I have to spend thousands of dollars fixing it this is nonsense with the low miles I have on it. …”
