2009 Volkswagen GTI Vehicle speed control Problems

“Epc light issue -which means electronic power control the vehicles computer suddenly cuts power away from the accelerater pedal causing rapid deceleration leaving the driver helpless to control the vehicles speed. I was merging onto a interstate into 70mph traffic and my epc light activated and left me unable to control my speed and safely merge into traffic almost causing a major accident -- very dangerous situation”

“This has happened several times beginning in march, 2018. Epc light comes on (seemingly) randomly. Occasionally, check engine light/service engine now warning will also come on. Sometimes they all shut off after letting the car sit overnight. Epc light comes on sometimes when we turn the car on and sometimes while driving. We have had three incidents where we try to get onto the interstate (70mph) and can't get above approx 40mph. I've almost been rear-ended twice because of this. On another occasion, I couldn't get the turbo to kick in. …”

“When I started the vehicle after it had sat for a week without starting, warning lights appeared for ABS, traction control, and brakes. I drove it around the block to test things out, and things seemed to be running pretty much like normal, so I drove it to a mechanic. They ran a diagnostic, and 8 codes came up, all having to do with the ABS system. It was determined that the ABS control module would need to be replaced. I didn't want to do the repairs at that mechanic, so they told me I could drive the car, but that I wouldn't have ABS or traction control. …”

“Abs faliure. Abs warning light activates, activates sporadically while driving randomly, braking ability is hampered, does not work normally. Occassionally antilock breaks engage at low speed breaking. Brakes do not function normally. Speedometer experienced malfunction, fluctuations not related to speed occured. Stability malfunctioned during breaking and automatic downshifting.”

“Instrument panel displays check engine light, steering light, ABS light, traction control light, brake light, tire pressure light. Abs no longer works in a hard brake situation, wheels lock and car will skid. Engine also refuses to rev past around 3900 RPM unless manually upshift to a higher gear. Steering assist no longer works.”
