On july 19, 2019, with 8800 miles on my 2018 bentley bentayga, i took it into an authorized bentley dealer repair shop for routine service. I was advised that the brakes, front, and back were dangerously low. There was no prior warning or indication of this problem. I had the front and back brakes replaced. In september 2022 with approximately 16,000 miles on the car, i noticed a squeaking noise coming from the front end of the car. On november 14, 2022, i took it back to the same authorized bentley repair shop. I was advised that the front brakes were dangerously low and needed to be replaced. The service man advised me that he had customers having their brakes go bad in this car in as little as 5,000 miles without notice..
Climate control intermittently operable. Only works half the time. Can't regulate the fan control as the touch screen control systems fails to work

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. There are nearly 100 connected devices in the car that is centrally managed using one computer systems that is very vulnerable. This is a fundamental problem at bentley hq, as one of the vulnerabilities was first identified in 1999, it was patched in 1999 and yet a 2017 car still has the vulnerability without any patch. This means not only is this car extremely vulnerable to cyber attack but the process to design the software in the factory had little to no regard to customer security. It is possible to electronically sweep all ip's in the usa searching for bentley bentagya's and then construct a cyber attack at all vehicles simultaneously. This is a very very serious issue. I notified bentley and provided the full cyber assessment report and had not reply whatsoever. They should immediately have every customer remove the sim card (this should be a critical recall) for the vehicle to prevent an attack from the other side of the world. Then they need to consider localised attacks as the car travels with a wifi bubble that is exploitable. This is how this report attached was prepared in the first instance.
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. Then on the highway when traffic is stopped or slow the car will drive at say 65 mph directly toward the stopped vehicles because the setting is set at 100 yards. The radar has the ability to see 300-400 yards, but in the shortened setting instead of looking out at 300-400 yards it disregards that input taking only the 100 yard input. What then happens is the car on realising that the stationary object is now at 100 yards attempts to do an emergency stop. Which is impossible. This happened by accident to me on a highway, and i have to swerve onto the hard shoulder to avoid a collision. If the manufacturer wants to install intelligent systems then it would be really helpful if they were designed right. It is absolutely possible to take a radar input at 300 yards and 100 yards from the system and then manage this situation safely. This is a basic design fault. They should go test a mercedes to see how to design this properly.
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. The issue is that when you are in a two lane road and the road markings in the centre line spread apart for a left turn area, the car will often follow the outside line instead of the inside line, that line taking you into oncoming traffic. You then need to violently yank the steering to correct he lane assist. I took the vehicle immediately to bentley after the second occasion and they failed again to find the fault. They asked me if i could video it happening - but that seems to make a dangerous situation more dangerous and i don't know when it is going to happen. This is the problem with self driving cars that are designed badly, it makes you incredibly nervous to drive as you never know what the car is going to do.
The auto start on this bentley bentagya most of the time does not work properly, but as i am now over 12,000 miles it has started to cause the car to call at odd times. 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. Annoyingly the bentley system does not seem to log the warnings and all the failures as every time i take this car to the dealer they claim they cant find the problem, despite having evidence in hand, such as a photo like this. You could call this car a lemon but you would be better to call to badly designed - there are some sever issues with this model most going directly to safety.
Bentley safeguard failure bentley safeguard is supposed to stop the car in the event of an obstacle. I was in the vehicle attempting to make a left had turn from the right hand lane on a two way road. The traffic was heavy but free flowing at around 20 mph. A large 18 wheeler truck flashed me to make the turn, so i started quickly to do the turn and as i got nearly half way across the road bentley safeguard stopped the car in the direct oncoming path of the truck. The semi then had to emergency break to avoid me as a stationary object in the middle of the road. He managed to do this stopping a few yards form the car. My son was in the passenger seat, he is 13 years old, and i was in fear that the truck could actually hit him and i could do nothing to get the car going again in time. I have now turned bentley safeguard off. The dealer claimed that the safeguard might be in the high alert mode, but regardless of which mode it is in it is dangerous. The semi driver was very upset and the horns blasted.
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. I have nearly hit a pedestrian because of the bad visibility on a relatively humid virginia day. A photo is attached
