I think it may be either fuel propulsion system or it maybe something electrical. I don-??t really know. It is available for inspection at this time as it has been at the car dealer repair shop for about a month. My safety is put at risk because about seven or eight out of 10 times that I attempt to start the vehicle, it will turn over by pushing the button, but will not start. I work until past dark many nights and my vehicle not starting is a big safety issue. The dealer said they reproduced it, but they have not been able to reproduce it again. Again, when I have it, it happens more than half the time. The dealer tells me they are communicating with the Buick engineers as the computer does not show any issues. They have so far not being able to determine the problem. there were no warning lamps or anything like that. It started happening occasionally when it was under warranty, I took it in twice to the dealer repair shop and they both said they could not reproduce the issue at that time. This is the third time I have brought it in and it is just past the end of my warranty.

Not safety, but GM recalled 2021Trailblazers to replace Evap Purge Pumps on vehicles showing check engine light resulting in bad purge pump diagnosis. Why only Trailblazers" I recently had to replace one on my 2021Envision at 37,588 miles after my check engine light came on. Fortunately I bought the extended insurance when I purchased my new vehicle and only paid the $100 deductible. Otherwise it would have cost me $404. If they knew of problems for that year, why not send out letters to other owners of GM vehicles" Thank you.

My vehicle's motor stopped without any warning in the middle lane of a busy freeway. I put the emergency flashers on but when I tried to restart the motor it overrode the flashers, causing a semi truck to just miss hitting me. The transmission went into Park mode and since this car is electronic shifting it would not let me put it in to neutral when the motor is not running. People stopped to help me push the car off the road but we could not get it into neutral. Very DANGEROUS situation to be stuck in a center lane on a busy freeway. ODOT and state police that stopped to help me said that they have never seen anything like this. Towed the car to a Buick-GNC dealer where they have had it for over 2 weeks now. They say that the fuel pump control module failed and they are on back order. My car has 11,200 miles on it.
