Problems with the Brakes

When hauling kids to school, parents want to know that the brakes are working correctly. Unfortunately, this particular BMW seems to have a lot of trouble with the service brakes.

Look at what one owner posted on the Bimmerfest Forum. “I can’t stand it anymore and everyone says it’s just the way it is because of the performance brakes. They squeak and squeal all the time.”

Because the brakes are mounted on the wheels, it makes sense to look at a wheel-related recall that was issued for the X6. It appears that the wheel bolts were not correctly tightened and could break off. NHTSA Campaign Number 18V614000 states that this can cause operators to lose control of the vehicle and crash. At that point, it won’t really matter how well the brakes are working. BMW created an “ultimate driving machine” until the wheels fall off.

Problems with the Suspension

The suspension system consists of several parts that need to work together for a smooth ride. Not only does the drive become rough when something is wrong, but it could lead to an accident.

Look at this NHTSA complaint. “Multiple issues with the front system and causes instability, issues with the suspension and the early warning system, never was fixed properly from [dealer].”

It turns out this BMW model is dealing with two suspension-related recalls. The first one, NHTSA Campaign Number 18V439000, states that the lower control arm may break. When this happens, it will become difficult to control the vehicle, and it might cause an accident. It turns out that the pivot bolt on the front lower-left control arm was not properly hardened. To repair it, BMW has to replace the control arm and bolt. The second recall, NHTSA Campaign Number 17V727000, talks about improperly torqued wishbone suspension bolts. Having loose bolts not only affects the performance of this vehicle but can also lead to an accident. There appears to be a common theme going on with this “ultimate driving machine.” In fact, nothing seems to be tightened properly, from the wheels to the suspension parts. It’s reminiscent of those cartoons where cars fall apart going down the road.

Problems with the Child Seat Anchors

Considering the 2018 BMW X6 is hailed as a family vehicle, it would be vital to have reliable child seat anchors.

Yet, when looking at the IIHS ratings of other popular models from the lineup, it’s evident that these vehicles struggle to keep kids safe. In fact, the IIHS listed the Child seat anchors, LATCH ease of use as “Marginal.” Likely, this study was performed before the massive recall affecting more than 32,000 vehicles.

While the IIHS doesn’t have any information on the X6, it’s believed it would reveal the same sub-par quality. Just look at NHTSA Campaign Number 19V823000, which illustrates that the lower child seat anchor bars might be damaged and lead to an increase in child injury. To fix the problem, BMW has to weld a reinforcing bracket into the vehicle body and lower anchor bars. Otherwise, kids in car seats are in a lot of danger. There’s really nothing ultimate about this driving machine, except for the number of defects. It surely takes the cake.

During operation in drive, the vehicle would shift to park, without the control lever being operated. This occurred intermittently, but with greater frequency over time. The safety concern is that it occurred while in traffic and even occurred on an interstate highway, while at momentary stop. When reported to bmw, the failure was isolated to the mechatronics, the components including electronic valve body, seals, etc. That control bmw automatic transmission functions. This is not a failure of an eco-mode or other fuel efficiency option. The item required costly repair, but confidence that a single part or system was isolated and repair is complete has not been confirmed.

We received a recall letter. There was apparently no fix available yet, rendering the vehicle unsafe to transport a child. I was advised by a bmw dealership they could get the parts. Have been waiting almost a week with no remedy and was told today that they were still trying. Called bmw corporate and they said the parts were in german and it was up to the local dealership to locate. They were unable to help. My car is unusable to transport my grandson and no remedy is in sight. Bmw is taking a "so what" attitude! This is an unacceptable safety situation. This is the information about the recall: nhtsa recall number19v823 recall statusrecall incomplete, remedy not yet available summary isofix child seat anchors: when attaching an isofix-type child seat (rigid-style connectors) to the vehicle's rear seat lower anchor bars, then over the lifetime of the vehicle, the bar(s) could become damaged. Safety risk if the lower anchor bar(s) became damaged, this could increase the risk of injury to a child in an isofix-type child seat during a crash. Remedy a reinforcing bracket will be welded to the lower anchor bars and the vehicle body for free and take several hours.
