2025 BMW 4-Series Common Problems by Component
2 owner complaints grouped by vehicle system.
ELECTRICAL SYSTEM
1 complaintSafety-relatedThe car has the fast wireless charging tray. I've attached a picture. The case for my phone has a small metal piece on the case. Its a regular case from Amazon. The wireless charger works fine, but it's also heating the metal phone cases to the point where it starts a small fire. Its a huge fire risk if you're not careful. We tried another case and we had the same problem.
VISIBILITY/WIPER
1 complaintSubject: Urgent Safety Complaint – Rear Visibility Obstruction in BMW 760i Due to “Theater Screen” and Rear Roller Shade Options To Whom It May Concern, I am writing to formally report a serious safety issue involving my recently purchased BMW 760i, equipped with two optional features — the “Theater Screen” and the rear window roller shade — both of which pose a significant hazard to driver visibility and road safety. The “Theater Screen” is a 31-inch ultrawide display that folds down from the roof for rear passengers. Upon activating this feature, the screen completely blocks all rear visibility through the rearview mirror. When I first engaged the system, I was immediately alarmed to find the rear view entirely obstructed, forcing me to turn it off and fold it back up to avoid driving blindly. In addition, the rear window roller shade, another optional feature I purchased, obstructs approximately 80% of the rear visibility when fully deployed. Both of these factory-installed and BMW-approved options create an extreme safety hazard, effectively disabling the driver’s ability to monitor traffic behind the vehicle — a fundamental requirement for safe operation on public roads. When I brought these concerns to BMW’s Customer Relations department, they dismissed the issue, stating that both features were “inspected and approved by the National Highway Traffic Safety Administration.” Frankly, it is difficult to believe that NHTSA would approve such features that blatantly compromise driver visibility and violate basic safety standards. I am therefore requesting that NHTSA urgently investigate this matter to determine how such equipment passed federal safety standards, and to ensure appropriate corrective actions are taken. These options place drivers, passengers, and the public at serious risk of collisions and injury. Thank you for your prompt attention to this critical safety issue.

How We Calculate Reliability Scores
Auto Reliability Index scores are calculated on a 0–100 scale using a weighted formula that combines multiple public data sources. Each factor is weighted based on its predictive value for real-world ownership experience.
Key Ranking Factors
Complaint Severity
NHTSA owner complaints weighted by component category (e.g., powertrain, safety systems, electronics, cosmetic) — safety-critical issues carry more weight than cosmetic ones. Adjusted for sales volume so high-volume models aren't unfairly penalized.
Repair Costs
Independent reliability ratings based on repair frequency, average repair costs, and severity of typical repairs for each model.
Recall Impact
Number of NHTSA recalls weighted by severity. “Stop driving” and fire-risk recalls are penalized more heavily than minor software or labeling recalls.
Issue Diversity
Measures how many major vehicle systems (engine, transmission, electrical, braking, etc.) have recorded complaints. A vehicle with issues spread across many systems may indicate systemic quality issues.
Scores are grouped into four tiers:
- 80–100: Excellent — Top-tier reliability, minimal issues
- 60–79: Good — Reliable with some minor concerns
- 40–59: Mixed — Notable issues, research before buying
- 0–39: Risky — Significant problems, proceed with caution
Data is sourced from NHTSA recall records, owner complaint filings, and independent repair databases. Scores are recalculated as new data becomes available. While the weighting model is proprietary, all underlying data sources are public and traceable.
