2016 BMW X3 — Problems, Recalls & Safety Data

The contact owns a 2016 BMX X3. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The RPM was elevated; however, the vehicle failed to respond as intended. The vehicle was driven to the shoulder of the road. No warning lights were illuminated. The vehicle was towed to an independent mechanic and was diagnosed with Electronic Power Steering Control Unit failure. The contact was informed that the Electronic Power Steering Control Unit needed to be replaced. The vehicle was not repaired. The contact was advised to tow the vehicle to the dealer. The vehicle was towed to the dealer, where the failure was confirmed as an Electronic Power Steering Control Unit failure. The contact referenced an unknown recall with a similar description; however, the VIN was not under recall. The contact was informed that the repair was not covered under the recall. The vehicle was not repaired. The manufacturer was made aware of the failure, and a case was filed. The contact was advised to contact the NHTSA Hotline to report the failure. The failure mileage was approximately 70,000.

The contact owns a 2016 BMW X3. The contact received notification of NHTSA Campaign Number: 24V608000 (ENGINE AND ENGINE COOLING, ELECTRICAL SYSTEM). The vehicle was taken to the dealer for the recall repair; however, the dealer refused to perform the recall repair and stated that since the vehicle was manufactured in Canada, the recall repair could not be performed. The manufacturer was not made aware of the issue. The contact had not experienced a failure.

The low-pressure fuel temperature/pressure sensor failed internally, causing diesel fuel to intrude via capillary action into the engine wiring harness and ultimately contaminate the Digital Diesel Electronics (DDE) control unit (ECU). The failed components (sensor, harness, DDE) are available for inspection upon request at BMW of Loveland, CO. My safety was put at risk in two primary ways: Engine Stalling Risk: The DDE is the engine control unit. As the fuel contaminated the electrical connections, the engine's reliability was compromised, creating a significant risk of sudden engine stalling while driving in traffic or at high speeds. Fire Hazard: The intrusion of diesel fuel—a combustible fluid—directly into the electrical wiring harness and the DDE created a clear fire hazard. Fuel near active electrical components poses a serious safety risk. Inaccurate Temperature Readings: The EGT (Exhaust Gas Temperature) sensor received incorrect readings due to the DDE/wiring issue, leading to potential engine damage due to excessively high exhaust temperatures. The problem has been confirmed by BMW of Loveland. The Service Director and their technical team identified the root cause in less than one day and confirmed it requires the replacement of the sensor, harness, and DDE. This was also validated by an internal BMW technical support case (TSARA). Gebhardt BMW failed to diagnose the issue correctly over three prior attempts starting in June 2023 through Aug 2025. Prior symptoms appeared over a period of months and included: Intermittent check engine light/MIL. Multiple, confusing diagnostic fault codes (related to air mass, charging pressure, and DPF efficiency). Increased frequency of DPF regeneration intervals.
