2024 Mini ConvertibleSteeringAcceleration & cruise control

On two occasions during the week before October 23, 2026, while driving on a freeway at approximately 50-60 mph, pressing the accelerator produced no normal acceleration and the vehicle slowed down. The dealer work order recorded speed dropping from about 50 to 35 mph despite the accelerator being fully pressed. This created a risk of being struck by faster traffic. The vehicle was presented to the servicing dealer on October 23, 2026, at 49,879 miles. The acceleration concern remains unresolved after an extended...

dealer test drive. Exact incident dates and the failed component are unknown. The incident date entered, October 20, 2026, is an estimate within that week, not a known exact date. Warning-light status is unknown. No crash, fire, injury, death or police report occurred. Separately, the steering became abnormally heavy and difficult to turn. Three dealer repair visits were needed before the steering concern was finally corrected. Dealer records reference steering repair orders dated June 23 and July 15, 2026. A later repair record describes binding front strut mounts and steering column, prior steering rack replacement, and eventual steering column replacement resolving the concern. An engine mount leak was also repaired. There have been approximately five or six service visits total. The vehicle is now at home. I request investigation of the unresolved loss of accelerator response and the repeated steering repairs.

2024 Mini ConvertibleOther & unknown

My 2024 MINI Cooper S Convertible, with approximately 50,000 miles, experienced two intermittent failures to accelerate while traveling on a freeway at approximately 60 mph, around October 14 and October 21, 2026. During both incidents, the accelerator did not respond normally, and acceleration returned only after multiple attempts. During one incident I was in the fast lane; the vehicle slowed traffic behind me and other drivers honked. There was no crash, injury, or property damage. I took the vehicle to...

2022 Mini ConvertibleBody, doors & structure

I was approaching a red light on a road that is 35mph. As I was coming to a stop my passenger side window shattered out of nowhere. There were no people around outside the vehicle and as I mentioned I was going so slow, I can't imagine any rock kicked up would have done this. There was glass everywhere in my car. Fortunately no one was in the passenger seat. There was a small amount of glass on my lap as the driver, but I was unharmed. I brought the car to the dealer. They did an inspection and cannot...

explain it other than saying maybe a rock hit it. They pointed out a very small dent in the door of the car, but that had been there previously. The rupture point was also closer to the top of the window (the windows were closed at the time of the incident), not where they workman pointed to. I asked the dealer to inspect the driver window when they replaced the shattered window. There were no warning lights to indicate this might happen. The car has been repaired so I can use it, but I have lots of pictures of what happened and the inspection video from the dealer.

2026 Mini ConvertibleWheels & tires

I purchased a 2026 Mini Cooper S Convertible in October of 2025. In the following 8 months I replaced 4 tires. Two due to blow-outs from potholes, a third went flat the morning after hitting a bump leaving a parking space due. The 4 incident was related to a bubble which formed on the sidewall of the tire. As the vehicle has no spar tire, three of the indicants required being towed to the dealership or the tire store. After nine months I replaced the vehicle. This vehicle is nether safe nor dependable.

My vehicle has active VANOS failure codes (131401 and 130304). These codes are preventing my car from passing the New York State safety and emissions inspection, rendering it legally unable to be used on the road. BMW/MINI Corporate is refusing to honor their national extended component warranty bulletin because they are conditioning the repair on a valid registration - which is a legal impossibility while the defect remains unaddressed.

While lowering the convertible top on my Mini Cooper Convertible, the trunk partition was not fully in place. Normally, the vehicle will prevent the roof from operating or provide a notification if the partition is not correctly positioned. In this case, the safety interlock system failed to warn me or stop the roof from lowering. While the roof was folding, the rear glass shattered, causing $6,000 in damage. The dealership confirmed that the rear parcel shelf was not fully in place and explained that the sensor...

only detects one side(in my case the trunk partition was in its place on one side ) , allowing the top to operate even when unsafe. They did not cover the damage under warranty. The vehicle was inspected by the authorized Mini Cooper dealership at the time of the incident. No police or independent inspections have been conducted. No warning lamps, messages, or alerts appeared, and the roof operated normally, giving no indication that the partition was not fully in place. The vehicle was only three months old. The shattered glass spread throughout the backseat and trunk area, creating a serious risk of injury to any passengers in the rear. Luckily no one was in the back at the time of the incident
