AUDI Complaints

The rear sub frame has completely rusted through, on both driver and passenger sides. This makes the vehicle extremely unsafe to drive. It is a 2014 q5 with 160k miles. There is a hole on the bottom of the frame on both sides due to a poorly designed cover that traps salt and other road debris leading to premature failure.

Dealer is refusing to acknowledge the known BSG defect (TSB 2058831/13) and is instead attempting to charge for secondary electrical failures (ABS/AC) caused by the primary charging system failure. 2023 Audi A3 2.0T, VIN [XXX] . Recurring 48V BSG (Belt Starter Generator) failure causing complete loss of power steering and brake assist. First documented under warranty October 29, 2025 at 45,500 miles at Audi Livermore (RO #XXX) — 48V battery at 0%, fault code P0A7D00. Dealer only recharged battery and erased codes without replacing BSG. Vehicle became completely undriveable March 22, 2026 with cascading electrical failures including CELO state, ABS failure, and complete loss of power steering and brake assist — a dangerous safety condition. Vehicle has been at Audi Livermore since March 26, 2026 — 40 days — unrepaired. Audi is now attempting to charge $3,751.70 for consequential faults caused by the unrepaired BSG.

We are reporting serious safety-related faults involving my leased 2026 Audi A6, VIN [XXX] , and a same-model 2026 Audi A6 loaner provided by Audi Central Houston. Core safety issues: 1. My vehicle previously displayed a Park/rollaway warning indicating Park could not be engaged. 2. My vehicle has had repeated starting-system faults, including: “Engine start system: malfunction! Please contact Service.” 3. Our vehicle has been the subject of multiple repair visits at Audi Central Houston and is currently at the dealer, available for inspection. 4. After the third repair order, Audi Central Houston represented the vehicle was ready for pickup. Before we accepted return, the same starting-system malfunction reportedly recurred during Audi’s own test-drive/verification process. Audi added that April 30 recurrence to the still-open third repair order. 5. While our A6 remained at the dealer, Audi Central Houston provided a same-model 2026 Audi A6 loaner. That loaner displayed: “P not possible. Risk of rolling away! Please contact Service.” A photo is available. 6. Because the loaner warning stated Park was not possible and there was a risk of rolling away, we did not leave it parked unattended and returned it directly to Audi Central Houston. The apparent failed/malfunctioning systems involve Park engagement, electronic shift-by-wire, transmission control, parking interlock, starting-system control, electrical modules, software, gateway communication, or related safety-critical controls. Safety is at risk because a vehicle that cannot reliably engage Park may roll away and injure occupants, pedestrians, bystanders, or service personnel. Audi Central Houston has inspected/serviced vehicle. Audi of America/VW Group has been notified under Audi Case No. XXX. We request NHTSA investigate whether 2026 Audi A6 vehicles have a safety defect involving Park engagement, rollaway risk, starting-system malfunction, transmission/electronic controls, software, INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA

Brakes were replaced by Audi with genuine Audi parts and within 2 months, the brake rotors became warped, requiring a resurfacing. After driving another 2 months, they once again became warped, making the entire car lurch and shake during braking.

My car has a known issue with a piston skirt defect that can cause engine failure. Audi of America acknowledged this issue with the EA839 and only warranted an 80k mile warranty. I am outside of that warranty and in risk of catastrophic engine failure that could lead to safety issues on the road. I am worried about my safety in driving this vehicle. Audi of America refuse to cover my car as it is outside of the extended warranty. There are numerous people that have the same issue as several models with the same EA839 engine and are prone to this failure.

Mechanic was checking the car and noticed subframe is rusted through underneath the plastic cladding. Audi dealers should cover this under warranty as it’s a safety issue. This happened due to poor designing.

Last week 4/28/26, I purchased four Crossclimate 2 235/50R19 tires from Costco in [XXX] . Order #XXX. My question is two of the tires do not have a DOT number on the side wall. Two tires have DOT [1426] Along with [047X]. The other tires only have [047X]. No week or year of manufacture. Those tires appear to have a white powdery coating on the sidewall. I asked the technician at Costco about the missing DOT date on two of the tires. He didn't seem to know what I was taking about. Is it legal to sell tires without the DOT manufacturer date? Are theses tires safe to drive? Thanks for taking time to answer this question. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am reporting a safety issue involving my 2016 Audi Q5. The vehicle previously underwent recall 20Z8/20W9, which addresses fuel pump flange cracking that can cause fuel leaks and fuel vapor odors. Despite this recall repair being marked as completed, I am now experiencing a strong gasoline smell inside the cabin. This appears to be the same condition the recall was intended to fix. When I called the authorized Audi dealership (Audi San Jose), I was told I would be responsible for diagnostic and repair costs because the recall had already been completed and is no longer covered. I believe this indicates that: The recall remedy may have been ineffective, or The defect has reoccurred This presents a potential fire hazard and safety risk. I am requesting that this issue be reviewed, as it appears the recall did not adequately resolve the safety defect. Date issue first noticed: [04/27/2026] Mileage at time of issue: [101k] Thank you.

I own a 2019 Audi Q8. The vehicle was in the dealership’s possession for approximately three (3) weeks for service. During that time, I was not informed of any significant mechanical concerns or issues. After retrieving the vehicle, it displayed an oil pressure warning while in operation. I immediately returned the vehicle to the dealership for evaluation. At that time, the dealership added oil (“topped off” the vehicle) and released it back to me without identifying or addressing the underlying cause of the warning. Following this, I made multiple attempts to have the vehicle properly diagnosed. I experienced difficulty obtaining assistance, including calls being disconnected, and I was not provided meaningful support or a thorough evaluation of the issue. Shortly after leaving the dealership, the vehicle began producing abnormal knocking noises and rapidly became unsafe to operate, requiring it to be towed. This situation presents a significant safety concern, as a sudden loss of power or drivability while driving can increase the risk of an accident, particularly in traffic conditions where maintaining speed is necessary. The condition has since been confirmed by a service provider as a major mechanical failure. Additionally, I have received documentation from the manufacturer indicating a known issue related to piston skirt defects associated with this vehicle. Despite the vehicle being in the dealership’s possession for an extended period, this issue was not identified, diagnosed, or addressed. I was also not provided clear assistance or guidance regarding potential warranty consideration related to this known issue. The vehicle is currently available for inspection upon request.
