Fuel pump after less than 200 miles.
Both front tires around 5K developed bubbles on the side walls of the tires. Cost to fix as not covered on warranty was $250 each. Pirelli all year.
Ignition coil at 35K.
Dash pixels burn out (didn't fix it).
But here is when things get bad...
I purchased a 2001.5 A4 in Oct 04 for $23K (Ultra Sport, xenons, and all the frills). I've done 42.8K miles and pampered the car. All maintenance by Audi. This is a certified car with 1 year on the Assured Warranty still left.
2 weeks ago I was on the highway, cruising at 70 mph, and while driving my battery died, then I felt a jolt, the lights were flashing on off till the car came to a stop. It could have been a bad accident. Anyway, the dealer as told me to change the timing belt. They say in this situation mileage wasn't a factor, but it was time. That the car was over 5 years old, so it was due. The dealer refuses to pay for this, and says it isn't covered on the Assured Warranty.
I called Audi of America, and they contacted the dealership, called me back, and conveyed the same message as the dealership, that either I pay $330 for the diagnosis, or $1200 for the belt (including $285 for new battery and $50 deductible for alternator and $330 for diagnosis). My car is sitting at the dealer as I write. On top of that, they refuse to give me a loner, because I towed the car from the highway instead of making an appointment.
If you are going to buy an Audi, sell it once the 4 year bumper to bumper warranty ends. They are very expensive to maintain.
The "Audi Assured" warranty is garbage. Audi will find ways to exclude anything of importance from this. If they do change a part, they will insist you get something else fixed to make up for their time.
The parts are over priced. I bought a battery for $285. Sears sells their Gold battery for $115 + $12 for installation.
The tires are $250 each at the dealer, plus extra for balancing etc. Sears sells the same tire with installation for $199. Online is even cheaper. "Assured Warranty" is the opportunity for Audi to rip you off.
