Audi Q5 won't shift problems

Filed Nov 8, 2026 · Engine · CA

The vehicle experienced a sudden and severe loss of engine power (limp mode) while driving, accompanied by a “POWER LIMIT” warning in the instrument cluster. Separately, the Advanced Driver Assistance Systems (ADAS) malfunctioned, including Emergency Assist / Medical Alert Assist (which autonomously pulled the vehicle over on two occasions) and Traffic Sign Recognition. The vehicle is available for inspection upon request. While accelerating at approximately 35 mph, the vehicle suddenly lost nearly all power and would only move at about 2 mph, creating an immediate hazard in traffic. On two separate occasions, the Emergency Assist / Medical Alert system pulled the car over without driver input. Traffic Sign Recognition also malfunctioned. These events nearly caused three accidents and have made the primary driver afraid to operate the vehicle due to the unpredictable loss of power and autonomous system interventions. The issues have been reported to the Audi dealer. We are awaiting formal confirmation and documentation of the findings. No police or insurance inspection has occurred at this time.” or “No formal manufacturer, police, or insurance inspection has been completed beyond dealer service visits. The instrument cluster displayed a “POWER LIMIT” warning during the power-loss event. Multiple ADAS warnings and system unavailability messages (including Emergency Assist and Traffic Sign Recognition) have appeared. The power-loss event occurred while driving at approximately 35 mph. The Emergency Assist pull-over events and traffic-sign malfunctions have occurred on multiple occasions since the vehicle was purchased in December 2025 (current mileage approximately 17,105).

Incident Description: While accelerating from a red light during rush hour, the vehicle suffered a sudden, catastrophic loss of steering control. The steering wheel locked completely and could not be turned. Simultaneous loud, long beeping and dashboard warnings appeared, stating: "Steering malfunction stop the vehicle immediately." The vehicle was immobilized in the middle of a highly congested, complex 5x5 intersection. Local police had to shut down traffic until the vehicle could be cleared. Safety Risk: Stalling abruptly in a major intersection during rush hour created an immediate risk of a multi-car rear-end pile-up. This jeopardized the safety of the driver and multiple children who were inside the vehicle, who faced a severe personal injury risk whether they remained trapped in the active roadway or attempted to exit. Diagnosis, Cost, and Recall Context: The vehicle was towed to an authorized dealership. Diagnosis revealed significant water intrusion inside the steering wheel wiring harness. Draining the water cleared the error and the vehicle become operational, but the dealership quoted $6,000 in repairs to replace the steering components completely out-of-pocket cost. Please note it appears the $6,000 quote will be out-of-pocket for catastrophic safety defects although they may be known issues for the same make and model years: Prior Gateway Recall: This vehicle’s VIN was previously impacted by the Gateway module recall (where water intrusion triggers a limp mode). That recall was redeemed prior to this event, and my understanding the repair should have prevented moisture intrusion. There seems to be a history on this make and model for known moisture intrusion causes critical issues. U45 Warranty Exclusion: The manufacturer issued a warranty extension for this exact steering failure on this same make and model years. However, this specific VIN was excluded from coverage, despite it being within the parameters.

Description of Incident and Safety Defect:Failed Component & Inspection Availability: The gateway control module, located in an unsealed floor compartment under the rear seat, failed due to liquid/moisture intrusion. The damaged module and vehicle are fully available for inspection upon request.Safety Risk: The sudden short-circuit of this module forced the vehicle into an immediate emergency "limp mode" and partial drivetrain shutdown while actively driving on the road. Unexpectedly losing engine power and throttle responsiveness in active traffic put my safety and the safety of surrounding drivers at an immediate, severe risk of a collision.Dealer / Independent Confirmation: The failure has been officially confirmed by an authorized Audi dealership service center. However, the dealer refused to perform a free safety repair because Audi has excluded my specific VIN from the active recall list.Prior Inspections: Outside of the diagnosing Audi dealership service center, the vehicle and failed component have not yet been inspected by the manufacturer, police, or insurance representatives.Warning Lamps & Prior Symptoms: Immediately prior to the drivetrain failure, the dashboard lit up with sudden error messages and warning lamps regarding a critical system malfunction. There were no gradual symptoms or warning signs leading up to this incident; the catastrophic module failure occurred suddenly due to moisture contacting the unsealed component.Summary Assessment:This vehicle has suffered the identical engineering defect and hazardous failure mode detailed in the federal safety agency Recall Campaign 21V‑947 (Audi Recall Code 90S9). Audi’s current recall window is too narrow. It must be expanded to include all 2018 Audi Q5 vehicles experiencing this exact, catastrophic safety failure, regardless of their production date cut-offs. To date the car has 89924 miles

On July 23, 2026, my 2023 Audi Q5 suddenly lost power while I was driving on the highway, with no prior symptoms before the incident. The vehicle began stuttering, entered limp mode, displayed multiple drive-system malfunction warnings, and developed a loud knocking sound from the engine area. The loss of power created a serious safety risk because the vehicle could no longer accelerate or operate normally in traffic. I pulled over as soon as it was safe, shut the vehicle off, and had it towed. The vehicle had approximately 74,945 miles at the time of the incident. An independent auto repair shop performed a diagnostic inspection and documented fault codes P030300 for a cylinder 3 misfire, P130A00 indicating cylinder 3 fuel injection had been disabled to protect the catalytic converter, and P013B00 involving the rear oxygen sensor. The technician reported severe connecting-rod knock from inside the engine block and found a large amount of metallic debris in the engine oil. The shop concluded that the engine had suffered catastrophic internal failure and required replacement. The symptoms and findings closely resemble the connecting-rod failure condition described in Audi recall 13i5 / the federal safety agency recall 22V753, although Audi advised that my VIN is not currently included. The vehicle is now at an authorized Audi dealership for further diagnosis. I am reporting this because the sudden loss of power and internal engine failure occurred while the vehicle was being driven and could have resulted in a crash. I request that the federal safety agency review whether my vehicle experienced the same or a substantially similar connecting-rod failure as the 2023 vehicles covered by recall 22V753, despite my VIN not currently being included.

If I have a sensor that will malfunction due to water then there should be a water indicator alert. My sunroof vent was blocked and water went into my trunk where the core module is. I had just come to a red light to turn on to a major highway and my car began to smell like fuel. I rolled down the windows and realized the smell was not as strong as inside. The light turned green and as I stepped on the gas the car went into limp mode as I was in the middle of my turn. The power steering then went out in the turn and the wheel yanked to the left and put me half way into the lane next to me. Thankfully no one was there. I had to yank it back to the right to get off of the highway on to the side of the road. I do not think that the power steering should be associated with that module or at least a water indicator sensor should be added. What happens if someone is on the interstate is driving 75 mph and their power steering goes out. It's in the shop and there is no damage other than now I am scared to drive it

Vehicle: 2022 Audi Q5 (VIN [XXX] ) Mileage at incident: ~20,000 Component: Powertrain – Engine / Turbocharger – Sudden Loss of Power NARRATIVE: On or about [XXX], my 2022 Audi Q5 experienced a sudden loss of engine power while driving approximately 60 mph. The vehicle began vibrating/shaking severely, jerking on acceleration, and displayed warnings including “Drive system: Please switch engine off” along with a check engine light. The vehicle entered reduced power/limp mode, creating a hazardous situation in traffic at highway speeds. The vehicle was taken to an authorized Audi dealer in Wayzata BLVD Minneapolis who diagnosed catastrophic internal engine failure and documented metallic debris in the engine oil. Audi replaced the engine with a new long block (warranty repair). However, despite confirmed metal contamination in the oil system, Audi directed the dealer to flush and reuse the turbocharger rather than replace it. The turbocharger is supplied by engine oil and may retain embedded metal in its bearing assembly, creating an ongoing risk of turbo bearing seizure/failure and another sudden loss of power at highway speed. I am reporting this because (1) the vehicle already experienced sudden power loss at highway speed, and (2) the repair decision to reuse a contamination-exposed turbocharger may create continued risk of sudden loss of power and unsafe operation. Dealer repair: Engine replaced; turbocharger reused after “flush.” Current safety status: I do not feel the vehicle is safe for highway driving due to risk of turbo failure and sudden power loss. Requested action: Please log and review similar complaints for potential investigation related to sudden loss of power and contamination-exposed turbo reuse in warranty repairs.

Water was spilled in the backseat of the car (less than 12 ounces of water). This caused a complete electrical failure impacting the engine and power steering. The failure happened at a slow speed in a parking lot but would have been much more dangerous on highway. The car would not turn on or off and would not shift into any gear after coming to a stop. Was told that the water caused a failure in the data bus control module.
