Dealers will install an electrical wiring harness with fuse protection for the PCV Valve heater in potentially affected vehicles, free of charge.

Prior to August 2024, this vehicle operated with zero check engine lights or drivetrain faults. In August 2024, BMW of Pittsburgh executed federally mandated Safety Recall 23V-707, which required opening the cylinder head. Immediately following this service, the Check Engine Light began illuminating persistently.On or about October 3, 2024, an independent diagnostic scan at Bobby Rahal BMW pulled BMW Factory Code 002A89: Exhaust VANOS Camshaft Mechanism Fault (Mechanical Sticking/Flow Restriction). Technicians at...

Bobby Rahal BMW explicitly instructed me to return the car to BMW of Pittsburgh because they suspected the original VANOS safety recall repair was botched.On October 28, 2024, I returned the vehicle to BMW of Pittsburgh to address this issue. Their technicians opened the engine block assembly a second time, yet failed to correct the defect. Following this second visit, the check engine light continued to come on intermittently. The vehicle began suffering rough idling, difficulty starting, and dangerous stalling events during operation. Cycling the ignition on and off provided only temporary relief.The check engine light has now become permanently illuminated. The safety hazards have severely escalated into a protective engine "limp mode," causing violent drivetrain shuddering and a catastrophic loss of driveability. BMW of Pittsburgh refuses to honor the recall workmanship, demanding a predatory $6,000 out-of-pocket teardown fee to bypass their liability. The manufacturer (BMW North America) has been notified under Case Reference VH78028, but the safety defect remains unaddressed, and the vehicle is completely unsafe to drive.

Engine & cooling

Due to BMW using plastic parts when you live in Hot and cold environments the plastic begins to mold to other plastic parts and pvc diaphragms tear rather easy causing rough idle , stalls and can cause over revving and send a car into another car while in gear. The cheap plastic cause oil leaks and when oil gets low cause engine failure as well.

On February 25, 2026, BMW of South Miami performed the VANOS safety recall repair on my vehicle. The repair order documented that VANOS bolts were missing and retrieved from the engine oil pan and that VANOS components were serviced. Within approximately 24-48 hours of picking up the vehicle, the check engine light illuminated and the vehicle began operating abnormally, including rough idle and irregular shifting. The vehicle stored diagnostic fault code P054B (camshaft position timing over-retarded), which...

directly relates to camshaft timing and the VANOS system involved in the recall repair. I returned the vehicle to the dealership for further diagnosis. The dealership stated an aftermarket camshaft position sensor with two O-rings was installed and removed one O-ring to correct the gap between the sensor and the camshaft reluctor wheel. The faults were cleared and the vehicle was returned to me. However, the check engine light returned again the following morning upon cold start, indicating the issue was not corrected. My service advisor has since stated that replacing the camshaft position sensor is not part of the recall repair and the dealership has declined to repair the vehicle under the recall. Because the malfunction appeared immediately after the VANOS safety recall repair and involves the camshaft timing system connected to VANOS operation, I believe the recall repair may not have been properly completed or corrected. I am requesting that NHTSA review this matter as a potential recall effectiveness issue, as the safety recall repair appears unresolved and the vehicle continues to experience faults related to the system that was repaired.
