What Problems Does the 2021 Audi A4 Have?
The 2021 Audi A4 generally enjoys decent reliability ratings, but some common issues have been reported. One area of concern is the potential for electrical system glitches, including issues with the infotainment system, sensors, and various electronic components. Some owners have reported minor software bugs or intermittent malfunctions.
Another area to watch is oil consumption. While not widespread, some owners have noted that their A4 may require more frequent oil top-offs than expected. It's recommended to monitor oil levels regularly and address any significant oil consumption concerns promptly.
Regarding recalls, it's essential to check the NHTSA website for any active recalls affecting the 2021 Audi A4. Recalls can address safety-related defects and should be taken seriously.
Long-term reliability hinges on adherence to the recommended maintenance schedule. Regular oil changes, fluid checks, and timely replacement of wear items are crucial for preserving the vehicle's performance and longevity. Some older Audi models have experienced issues with the timing chain tensioner, but it's not a prevalent issue reported specifically for the 2021 A4. It is still a good practice to listen for any unusual engine noises that might indicate a developing problem. It's also important to be aware that repair costs for Audis, including the A4, can be higher than average due to the complexity of the vehicle and the cost of parts.

How Does the 2021 Audi A4 Compare to Other Passenger Sedan?
The 2021 Audi A4 competes with the BMW 3 Series, Mercedes-Benz C-Class, Lexus IS, and Acura TLX. Compared to the BMW 3 Series, the A4 offers similar performance and handling but may be perceived as slightly less sporty by some drivers. The Mercedes-Benz C-Class provides a comparable level of luxury and technology but can be more expensive. The Lexus IS is known for its reliability and comfortable ride, but its infotainment system isn't as modern as the A4's. The Acura TLX offers a more aggressive design and available SH-AWD system but may not match the A4's interior refinement.
In terms of reliability, the Lexus IS generally scores higher, while the German competitors can be more prone to issues. Price-wise, the A4 sits in the middle of the pack.
Alternatives to the A4 include the Volvo S60, which offers a stylish design and a focus on safety. If reliability is a top priority, the Lexus IS is a strong contender. For those seeking ultimate driving dynamics, the BMW 3 Series might be a better choice. The Genesis G70 also warrants consideration as a value pick offering compelling features and performance at a lower price point.
