Audi A4 Reliability

Want to more clearly know what the difference in reliability will be if you buy a Audi A4 rather than another vehicle? Concerned about your chances of getting a lemon?

TrueDelta provides this information in the form of "times in the shop" stats that make the actual repair rates clear and, in the future, "lemon-odds."

The latest Car Reliability Survey (CRS) results include Audi A4 reliability information based on owner experiences through June 30, 2010:

Successful Repair Trips per Year (per 100 vehicles)
Year	Make	Model	Trips / Year per 100	TS	Cars Mon/Car Av Odo
2010	Audi	A4	36 Fewest         Most Second model year, much better than people expect from an Audi so far. S4 repair frequency similar to the A4 once consider lower average odometer.		68 5.0 5900
2010	Audi	S4	27 Fewest         Most Second model year, much better than people expect from an Audi so far. S4 repair frequency similar to the A4 once consider lower average odometer.		29 3.1 3900
2009	Audi	A4	72 Fewest         Most First year of the B8, and appears to continue the average repair frequency of the B7 A4. Common problem with the front suspension.		105 8.0 11800
2008	Audi	A4	59 Fewest         Most		47 7.7 25000
2007	Audi	A4	55 Fewest         Most Small sample size for S4 performance variant. Seems to require fewer repairs than the A4 on which it's based, but note lower average odometer.		69 7.5 38200
2007	Audi	S4*	join to view		17 6.9 30700
2006	Audi	A4	85 Fewest         Most Includes 2005.5. Much lower repair frequency than B6 A4. Small sample size for S4 performance variant. Seems to require fewer repairs than the A4 on which it's based, but note lower average odometer.		105 7.5 52300
2006	Audi	S4*	join to view		17 7.9 42700
2005	Audi	A4	145 Fewest         Most		29 6.8 64900

2004	Audi	A4	152 Fewest         Most		35 5.2 69800
2004	Audi	S4	126 Fewest         Most		25 7.2 61500
2003	Audi	A4	103 Fewest         Most Lower reported repair frequency than the 2002 or 2004. Possibly because sample size is just a bit over the minimum for a full result?		29 6.4 90000
2002	Audi	A4	148 Fewest         Most		50 6.7 98200
2001	Audi	A4 / S4*	join to view		18 6.0 102600

We also have some new reliability stats for the Audi A4. "Nada-odds" reports the percentage that required no repairs at all, not even a minor one--nada--in the past year, while "Lemon-odds" reports the percentage that required three (or more) repair trips.

Nada-odds     cars per 100 with no repairs (nada) in the past year; 100 is ideal Lemon-odds     cars per 100 with 3+ repair trips in the past year; 0 is ideal
Year	Make	Model	Nada-odds per 100 cars	Lemon-odds per 100 cars	Cars Mon/Car Av Odo
2009	Audi	A4	53	6	54 11.3 17300

2007	Audi	A4	74	< 1	32 11.6 42600

To provide comprehensive results, TrueDelta needs reliability data on all cars--not just the Audi A4--from people like you. To encourage participation, those who help provide the data receive free access to the site's car reliability information. Find out the details.

Audi A4 Repair Histories

To supplement our Car Reliability Survey, TrueDelta collects Audi A4 repair histories, a list of all the repairs that have been performed on a vehicle. With these, no minimum sample is required and owners can report repairs that occurred before joining.

Individual responses to both the Car Reliability Survey and the Car Repair History Survey are posted here:

Audi A4 Extended Warranty

Concerned about the Audi A4's reliability? Considering an extended warranty? Warranty Direct is a 26-year-old company with nearly 2 million contracts sold and over $500 million in paid claims.

Like insurance, extended warranties are best bought to limit downside risk, and from a company that is almost certain to remain in business. While for most people extended warranties will not pay off, for some they will pay for themselves many times over.

If you are unsure about the Audi A4's reliability, or simply want the peace of mind afforded by an extended warranty, you can click here to purchase one from Warranty Direct.

Audi A4 Gas Mileage

Everyone knows that government estimates often aren't indicative of the Audi A4's gas mileage in the real-world.

In response, TrueDelta began collecting gas mileage data from owners of the Audi A4, with the intent of providing real-world gas mileage estimates customized to how and where you drive.

"Why (Not) the Audi A4?" Reviews

For car buyers' reasons for buying a A4--or not--click here.

Want another perspective? Since 1999, Michael Karesh, the developer of TrueDelta, has contributed reviews to Epinions, where he is one of two people who oversee the autos section.

Michael's most recent Audi A4 review.

Note: The older the review, the more likely it has become outdated owing to more recently introduced competitors.

Audi A4 Tire Reviews

The Tire Rack offers the Internet's most extensive collection of Audi A4 tire reviews, tire survey results, and tire tests. To see which tires are available for the Audi A4--or for your car--and go from there to Tire Rack's comprehensive information, use the tool in the sidebar.

The Tire Rack can be especially useful as a source of winter tires, which I have strongly recommended ever since buying a set for my car. If you're unhappy with your car's handling and braking on snow and ice, you probably just need proper winter tires, not a new car.
