2021 Audi Q5 Electrical System Problems
One of the more common electrical system problems present in the 2021 Audi Q5 is the appearance of an “electrical system malfunction” message, which has caused some owners difficulty with starting the vehicle.
In some cases, other warning lights may also appear on the dashboard, further complicating the situation. Drivers have also noted problems with the infotainment system, particularly the screen freezing or becoming unresponsive.
Another issue concerns sensor failures, including those linked to the parking assist and collision warning systems.
These malfunctions can lead to diminished safety features, which are crucial for driver confidence.
Additionally, some owners have reported unexpected battery drain, which results in starting problems and a lack of reliability.
In addition to these ongoing issues, there have been several important recalls related to the electrical system.
One major recall, initiated on December 8, 2021, is NHTSA Campaign Number 21V-947, which addresses a potential gateway control module shutdown that could reduce engine power, increasing the risk of a crash.
The issue stems from a liquid spill in the rear seat area or water ingress from an insufficient body seam underneath the vehicle, which may allow liquid to penetrate the control module.
Audi has been proactive in remedying this by installing a protective cover on the module and sealing the underbody seam as needed, at no cost to owners.
On October 5, 2022, another recall was issued (NHTSA Campaign Number 22V-742) concerning the rearview display.
Due to a software issue, some 2021 Audi models, including the Q5, experienced a blank or black screen on the rearview camera when the vehicle was placed in reverse.
This defect failed to meet Federal Motor Vehicle Safety Standard 111, compromising rear visibility and increasing the risk of a crash. Dealers have been instructed to update the infotainment software to resolve the issue.
A third recall, issued on December 13, 2023 (NHTSA Campaign Number 23V-842), addresses overheating of the power outlet or charging cable, which could potentially lead to a fire.
Audi has advised owners to avoid using the 220V/240V compact charging cable and to use the 110V home charging cable or public charging stations instead.
A new 220V/240V cable with an integrated temperature sensor will be provided free of charge by dealerships.
2021 Audi Q5 Engine Problems
The 2021 Audi Q5 may be prone to several different engine problems that can impact both the performance and safety of the vehicle.
One of the most concerning issues is unexpected engine stalling. Some owners have reported that the engine stalls without warning, which can pose a significant risk, especially while driving at high speeds or in traffic.
Another common complaint is rough idling, where the engine does not maintain a steady idle, leading to a less smooth driving experience and potential discomfort for the driver and passengers.
Additionally, some owners have faced issues with coolant leaks, which have sometimes appeared without any prior warning indicators.
These leaks can lead to engine overheating, further damaging critical components if not addressed promptly.
In more severe cases, metal fragments have been found within the engine, resulting in extensive damage and often requiring engine replacement.
There have also been reports of engine failure in extremely cold temperatures, which can be both inconvenient and a serious safety concern.
If you’re experiencing any of these engine-related problems with your 2021 Audi Q5, it’s crucial to have the vehicle inspected by a certified Audi technician as soon as possible.
Timely maintenance and early intervention can help prevent more serious and costly issues down the line.
There has also been a significant recall for the 2021 Audi Q5 related to engine problems. On October 7, 2022, NHTSA issued Campaign Number 22V-753 due to damaged engine connecting rod bearings.
This issue can cause engine failure or a stall, increasing the risk of a crash. If the failure leads to an oil leak, there is an additional risk of a fire.
Audi has stated that dealers will inspect the affected engines and replace them if necessary, free of charge.
If you’re affected, owner notification letters were sent in December 2022, and owners are encouraged to contact Audi customer service at 1-800-253-2834 for more information.
2021 Audi Q5 Powertrain Problems
One common powertrain problem reported in the 2021 Audi Q5 is transmission shuddering, where owners have noticed the vehicle shaking when coming to a stop or while making a turn, particularly at lower speeds.
This issue has often been linked to problems with the 4-WD clutch and rear differential, which can affect the smoothness of the vehicle’s acceleration and deceleration.
Another significant concern involves unexpected shutdowns. Some owners have experienced the vehicle shutting down without warning while driving, with moisture potentially getting into the gateway control module.
This issue can result in a loss of power and, in some cases, pose a safety risk. Transmission failure is another problem that has been reported, with drivers experiencing warning messages like “Transmission Engine Failure” on the instrument panel.
This can lead to complete transmission failure if not addressed promptly, severely impacting the drivability of the vehicle.
If you’re experiencing any of these powertrain problems with your 2021 Audi Q5, it’s strongly recommended to have the vehicle inspected by a certified Audi technician.
Regular maintenance and addressing these issues early can help prevent more severe damage and keep your vehicle running smoothly.
2021 Audi Q5 Suspension Problems
The 2021 Audi Q5 may have notable suspension issues, particularly concerning the rear axle. One of the most significant problems is a faulty lock nut in the rear axle assembly, which can cause misalignment and lead to uneven tire wear.
This misalignment can make the vehicle pull to one side while braking or accelerating, affecting handling and safety.
In response to this issue, Audi issued a recall under NHTSA Campaign Number 21V-295, which impacted 40,993 vehicles.
This recall was issued due to stress corrosion potentially causing the lock nut on the trailing arm of the rear axle to break.
As a result, dealers were instructed to replace the lock nuts and associated bolts free of charge.
Additionally, there have been reports of air suspension issues in the 2021 Q5. Some owners have experienced a deterioration of the air suspension system over time, leading to a rougher ride and potentially higher maintenance costs.
While this is not as critical as the rear axle misalignment, it remains a common concern for owners.
Another recall related to the suspension in the 2021 Audi Q5 was issued under NHTSA Campaign Number 22V-034.
This recall addressed the rear axle misalignment that may have occurred following the previous recall (21V-295), as the alignment may not have been inspected after the necessary repairs were made.
If misalignment was present, it could cause premature or uneven tire wear, increasing the risk of a crash.
Audi instructed dealers to inspect the rear axle, adjust the alignment if needed, and replace any tires that were unevenly worn at no cost to the owner.
If you are experiencing any suspension issues with your 2021 Audi Q5, it’s strongly recommended to have your vehicle inspected by a professional to ensure that these issues are addressed promptly.
Audi Q5 Owner Complaints
“Gateway control module shutdown. After a rain storm vehicle had electrical issues such as rear light turning off, and engine start malfunction alarm on dashboard. To vehicle automatically stoping with no vehicle nearby, seat belt tightening and to engine seized while driving to the dealer for the “engine start malfunction alarm”. The Audi dealer is quoting us $17,000 to repair for damages. Multiple people on this post have also had this issue with one going on 4 months waiting for parts to repair this issue.”
“When driving in extreme cold (ambient temperatures of -35 or colder) and I reach a speed of 50mph or higher, my engine fails. The dealership refuses to resolve this issue although they’ve had my vehicle twice now, both for months at a time- and the dealership is 400 miles away from me.”
“I purchased a brand new 2021 Audi Q5 in November 2020. 4 months later, wires on the bottom of the SUV cut into pieces in 4 different locations and the coolant start leaking. All the dashboard lights are lit on. The SUV wasn’t functional. When I talked to the dealer, they told me to put a claim on the insurance to fix the troubles. Worst SUV, Never buy this one.Dealer told that same thing happened to these SUVs before.”
Your Car and the Law
If you are dealing with persistent issues with your 2021 Audi Q5, you may qualify for protection under lemon law regulations.
This consumer protection law exists to support buyers or lessees of vehicles that fail to meet quality and performance standards, despite repeated repair attempts while still under warranty.
If your 2021 Q5 has required multiple repairs for the same or similar defect—especially one that affects safety, functionality, or the overall value of the vehicle—you might be entitled to remedies such as a refund, replacement vehicle, or financial compensation.
Lemon law remedies differ by state, but often include a full refund, a replacement vehicle, or monetary compensation.
