A vehicle diagnostic scan dated 04/15/2026 at approximately 88,502 miles showed a stored transmission electronics fault: P084100, described as “Transmission fluid pressure sensor/switch A range/performance,” with status listed as passive/sporadic. This indicates a transmission / powertrain control concern involving the transmission fluid pressure sensor, transmission electronics, wiring, control logic, pressure monitoring, or related powertrain components. The vehicle also has prior…

A vehicle diagnostic scan dated 04/15/2026 showed electrical communication faults involving vehicle control modules. The scan showed U014100, described as “Lost Communication With Body Control Module ‘A’,” with status listed as passive/sporadic. The scan also showed U112100, described as “Data bus message missing,” with status listed as active/static.

The sunroof has a recurring mechanical/electrical malfunction. During operation, the sunroof binds and makes a loud popping or cracking noise, and the rubber seal became torn or damaged. This suggests a possible track, guide, cable, motor, regulator, frame, seal, or alignment failure. This is being reported as a safety concern because a binding or popping sunroof can distract the driver, allow water intrusion into electrical areas, worsen into glass/track/frame failure, or create a risk of…

2018 AUDI A4

Filed Jul 1, 2026


An Audi dealer installed 245/40R18 93H tires on this 2018 Audi A4, while the vehicle placard/specification requires 245/40R18 97H. The lower load index reduces capacity from 1,609 lb per tire to 1,433 lb per tire, approximately 704 lb total across four tires. This creates a safety risk because load-rated tires affect vehicle stability, heat buildup, braking, steering/cornering, suspension loading, and tire failure/blowout risk. After discovering the mismatch, the concern was reported to the…

The exterior side mirrors have intermittent electrical/memory malfunctions. When locking the vehicle, the side mirrors begin to fold, pause or glitch briefly, and then continue folding. Separately, when the vehicle is shifted into reverse, the right-side mirror tilts downward to assist with backing/parking, but when shifted back to drive or park, the mirror does not reliably return to its original saved position and requires manual readjustment. This is being reported as a safety concern…

The rear-view camera intermittently fails to engage when the vehicle is shifted into reverse. When the camera does display, the image sometimes shows horizontal glitch lines/artifacts. This affects backing visibility and parking safety and creates a risk of collision with pedestrians, objects, vehicles, or property. The concern was reported to Audi service along with other electrical/driver-assistance symptoms, suggesting a possible camera, wiring, module, signal-processing, or broader…

The vehicle displayed a low coolant warning and the coolant reservoir was low. Audi dealer service records dated on or about 02/14/2025 document the concern as: “client states low coolant warning was on, coolant reservoir is low, diagnose and advise.” The dealer performed coolant-related work involving the thermostat gasket / coolant hoses or connections to the coolant reservoir, ran the vehicle to operating temperature, and rechecked. The concern is being reported because the coolant…

Visible wiring has become exposed in the windshield/A-pillar area. There is no airbag/SRS warning light at this time, and I am not able to determine from visual inspection whether the exposed wiring is related to the restraint system. However, this is a safety-sensitive area because it can contain or route electrical wiring near trim, sensors, and safety-system areas. Exposed or unsecured wiring in this area may create a risk of electrical short, damaged wiring, impaired signal integrity, loose…
