CATASTROPHIC SAFETY ISSUE MANY of the warning lights on the instrument cluster are illuminated. These include: * ABS is steadily illuminated. * Airbag is steadily illuminated. * The speedometer is not functioning showing "0" so I can't tell how fast I'm going. * The steering system indicator light is steadily illuminated. * Check Engine/Engine Malfunction is intermittent. * The Electric Power Control indicator is intermittent. * ESP/ASR is steadily illuminated. * The Alternator indicator light is intermittent * Tire Pressure Monitoring is steadily illuminated. * The fuel gauge is moving ranging from empty to full therefore the low fuel indictor flashed frequently. * Several times when depressing the accelerator instead of gaining power, acceleration dropped off. In traffic, at highway speeds, this is an additional serious safety issue. I HAVE MADE NO MODIFICATION TO THE VEHICLE OTHER THAN REGULAR MAINTENANCE AND NEW TIRES. I took the car to the local dealership where the on-site technical advisor speculated that the wheel speed sensor was at fault. This did not build confidence.

I don't drive my car often as I work from home and travel out of town all the time. I only have 16k miles on my car despite of owning it for 3 and a half years. Recently, the check engine sign showed up on the dashboard. The issue came out to be with the failed bank 1 oxygen sensor 1. It's pretty rare for a car with less mileage to have such issues. As I'm over the three year mark, the fix was not covered under warranty.

I purchased a volkswagen passat diesel and decided to keep it even after the whole diesel scandal. Two months after the second part of the "fix" my check engine light comes on so I decided to take it to the dealership because my warranty was extended through the whole diesel lawsuit. I was told that my high pressure fuel pump failed because of bad diesel. I asked the service center how they determined my bad diesel was tested and they demonstrated a vw approved special tool with a box that had a smiley face and frown face emoji. The repair facility advised me that they could't perform the repairs under warranty because of the poor quality of the diesel. I called volkswagen of america and got the run around. I had to use my vehicle's car insurance to cover the $7400 repair bill. As a ten year veteran volkswagen/audi technician I/we are well aware of the design flaw of this high pressure fuel pump. The pump fails and sends metal fragments throughout the entire fuel system all the way back to the fuel tank. I would be ok replacing a $800 high pressure fuel pump but this design allows the metal from the high pressure fuel pump which is driven by the timing belt to recirculate back into the tank and further contaminate the entire system and not to mention the four fuel injectors at $500 a piece (times four). I called the volkswagen diesel settlement line and explained my frustration and even made the person who answered the phone laugh with the whole smiley face and frown face tester. I am a factory trained technician and even I don't understand the logic behind this, give me percentages and tolerances which I can understand. Unfortunately this will be my last volkswagen I will ever purchase I know this doesn't matter much to vw but I will be definitely spreading the word.
