2024 BMW I4 Problems

As I was easing my 2024 BMW i4 xDrive40 onto Church Street from a cross street on May 11, 2026, my car suddenly accelerated and crashed into the car in front of me. The acceleration was "un-commanded." The accident occured a bit before 2:20 pm. Driving conditions were ideal. I had the car in Eco Mode, and I was using one-pedal driving (braking when one eases up on the accelerator pedal). When the car becan accelerating. I believe that I had time to depress the brakes, but it was to no avail. There were no reportable injuries and no police report. My car has automatic emergency braking, and on two separate occasions the car braked suddenly when "it" thought that I was approaching a car to quickly. It did not function in this instance to stop my car from crashing into the car in front of me. I had never previously seen the car behave like this. I had owned the car since its initial purchase in August of 2024.

am writing to report an incident involving my vehicle. While entering my driveway, the vehicle unexpectedly accelerated and did not recognize that the garage door was closed. As a result, the vehicle collided with the closed garage door and subsequently struck the structural beam on the wall near the garage entrance. The impact was significant, and all six airbags deployed. At the time of the incident, I was driving, and my teenage son was seated in the front passenger seat. Both of us sustained minor injuries. However, the incident resulted in substantial damage to both the vehicle and the garage/property.

I had a rear-end collision on [XXX}. The car was scheduled for repair on 3/19/2026. On [XXX] at ~70,000 miles, my 2024 BMW i4 eDrive35 (VIN: [XXX] ) experienced a drivetrain malfunction with reduced speed. The dealership diagnosed an internally faulty A/C compressor with metal shavings contaminating the system and recommended replacement of the compressor, condenser, chiller, expansion valve, and system flush. BMW denied goodwill repair and my insurance claim was also denied. I have filed a complaint with the New Jersey Department of Banking and Insurance and request NHTSA document and investigate this defect due to potential safety risk.

I am reporting a serious and recurring safety issue with my 2024 BMW i4, which I leased new in December 2023. The vehicle currently has approximately 20,000 miles and has stalled multiple times at high speeds, displaying a drivetrain malfunction warning and issues related to the power supply and high-voltage battery system. This is extremely dangerous, especially in high-risk driving environments such as highways, bridges, and tunnels in Manhattan. A sudden stall compromises power steering and braking and could easily lead to a fatal crash. I have already had the vehicle towed to the service center three separate times, yet the issue remains unresolved. Given the repeated nature of this failure in a relatively new vehicle, I am deeply concerned this may be a broader defect in the i4 model and urge the NHTSA to please investigate. This issue has happened three separate time within the span of only 2 months. I am extremely worried and do not trust the car nor feel safe to operate it. I've included the two repair invoices I've received from BMW so far and the vehicle is currently at the service center for it's third attempt.

Sunroof spontaneously exploded with no sign of impact

On March 2, 2025, while driving my BMW i4 with my daughter, the vehicle suddenly spun out twice into oncoming freeway traffic during a routine lane change, violently crashing into an embankment. Thankfully, we weren’t physically hurt, but my daughter was deeply traumatized. We brought the car to Stevens Creek BMW immediately. What followed only made things worse. Rather than investigate the serious safety failure, the service team blamed us—citing the i4’s heavy battery as the cause. They admitted it causes accelerated tire wear but denied any responsibility. They also falsely inflated our mileage to 22,892 miles (actual: 15,109) to justify the wear and shift blame. BMW is now demanding over $10,000 in repairs and has threatened $110/day in storage fees—pressuring us as we seek a fair solution. As longtime BMW customers, we trusted the brand with our safety. That trust is gone. A car under a year old should not spin out from normal driving. This is a clear safety defect. Efforts to escalate through BMW Consumer Services failed: the listed support email bounced, and the Consumer Advocacy page led to a dead link (screenshots available). That page has since been removed—highlighting a broken system. Unprofessional Conduct & Lack of Transparency At the dealership, I was treated dismissively for raising concerns and forced to return the loaner car despite no resolution. We’ve had to rent a car while still paying $776.64/month for an undriveable lease. BMW also refused to share the inspection report allegedly conducted by BMW USA engineers—despite initially promising it. BMW staff admitted the i4’s heavy battery causes premature tire wear—a known risk never disclosed at lease signing. This vehicle should never have been released without warning consumers. We no longer feel safe in this vehicle. We respectfully request: Lease Termination & Buyout — BMW to fully cover the lease as nothing they've offered us reflects the trauma, risk, or poor treatment we’ve endured.

Summary of the Problem: While driving my leased BMW i4 M50 on the highway on [XXX], the rear passenger tire suddenly exploded without any prior warning or impact. This caused me to lose control briefly and nearly resulted in a serious accident. I was forced to pull over in unsafe conditions on a busy roadway. Details of the Incident: The tire failed suddenly while traveling at highway speed. No pothole, debris, or curb impact occurred prior to the blowout. I contacted BMW Roadside Assistance immediately, but was told it would take at least two hours before anyone could arrive, leaving me stranded in a dangerous location. The vehicle was towed the next day, [XXX], to BMW of Sacramento. The service department dismissed the issue and told me it was not their problem, refused to cover the tire failure, and even told me to go rent a car from Enterprise instead of providing a loaner. Safety Concern: This is a new EV leased vehicle and the sudden tire failure presented a serious safety hazard. A tire blowout at highway speeds could easily have caused a crash with severe injuries. The lack of immediate roadside support further increased the danger. The dismissive response from the dealership raises concerns about whether BMW is properly addressing potential tire or component defects in this vehicle. Action Requested: I am reporting this incident because I believe this may represent a defect or safety issue that warrants investigation. A sudden tire explosion on a new BMW EV, combined with BMW’s inadequate safety support, puts drivers and the public at significant risk.

On July 4th, 2026 we were driving home in a storm. The windshield wipers failed while in the automatic setting, completely shutting off, creating a safety hazard. We pulled to the side of the road and restarted the vehicle. Afther the reboot they had resarted, but agian failed within ten minutes. We pulled over again giving the car more time to cool/reset and contacted BMWs internal SOS service. They could not hear due to the rain coming down on the car. Eventually we were able to proceed home with the wipers on a low setting. We took the vehicle to the dealership. They were unable to reproduce the defect, calling it an anomally in one video. The BMW techs are the only one to have inspected the vehicle. As for warnings, there were none. It was just a system failure mid-storm with no proceeded or forwarned error codes.

The vehicle experienced two sudden and complete losses of power, on December 29, 2025, and again on February 18, 2026. In both instances, the vehicle became inoperable while in motion and required towing. These failures created hazardous roadside situations.

Mechanical failure on the car air suspension especially on back left of the car. Car parked overnight and it automatically lowered and driving it out of the drive way there was no error that popped out on low suspension until driving out of drive way. That caused the scratch on left side under carriage. Dealer refused to run diagnostics to determine true cause of issue until we pay for the diagnosis although this car is newly purchased and covered under warranty period. Dealer is trying to put the blame on me although it is a malfunction with the cars air suspension. Read that this problem happens to i4’s often on forums and I don’t feel safe driving the car until this issue is resolved but I’m unable to proceed without proper diagnosis from BMW service.
