What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The contact stated that the air bags did not deploy. A police report was not filed. The contact sustained two fractured wrists and a spinal injury that required medical attention. The vehicle was not drivable and was towed to an independent mechanic where the vehicle was not diagnosed or repaired.
The vehicle was taken to the dealer where it was diagnosed that the fuel line was fractured and the fuel tank needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 35,500.
Easy cyber attack against new bentley - critical issue it is incredibly dangerous to connect this car to the internet using a sim card, as the car is littered with high impact vulnerabilities that can easily be exploited to shut down systems, this would deny service of systems, like steering or brakes, or airbags.
Bentley dynamic cruise control - dangerous the car has dynamic cruise control that is very dangerous in certain settings. It is possible to shorten the distance to the next car on a highway to approximately 100 yards, and the car will continue at the cruise if there is no car in front.
Bentley lane assist - major issue the bentley lane assist is supposed to keep you in a lane, however twice now I have been travelling on a two way road and it has taken me with a violent steering manoeuvre into oncoming traffic.
For example coming out of a parking space the car stalled leaving me half in and half out the space. It also stalled at a traffic light 3 days ago. Then the warnings common and then go off, finally I captured this warning on camera.
The bad design of the bentley bentayga ventilation system at the front causes the screen to steam up all the time in humid weather making it very hard to see out the front window. You clean it and it is steamed again in 5 seconds.
1 the car will slip into neutral when you take your foot off the gas, even in terrible weather. This means no gear is actually engaged, and if an emergency occurs it has to first find a gear before you can utilise power.
