Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Unpredictable problem. Occasionally, 5 to 15 seconds after I first start my 1999 Mustang Gt, the engine will rapidly increase in RPM and then return to normal. If the car is in drive or reverse and I do not have my foot firmly on the brake, the car will jump forward or backward. I notice the problem mostly when I first put the car in reverse. It may happen 3 or 4 times in one month and may not happen again for 2 or 3 months. If you do not have the brake applied firmly, I think the car could easily jump 5 feet before getting a foot on the brake. I currently have 29,000 miles on my car. …”
