2021 Buick Envision

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.

The contact owns a 2021 Buick Envision. The contact stated that while operating the vehicle, the contact heard a popping sound coming from the front end of the vehicle, and the vehicle became difficult to steer. The vehicle was taken to the local dealer who determined that the front driver’s and passenger’s side ball joints, and control arms were faulty and needed to be replaced. The vehicle was repaired but the failure reoccurred, and the control arms were replaced a second time. Also, while driving the odor of fuel was present inside the cabin of the vehicle and the vehicle hesitated and jerked while depressing the accelerator pedal. The vehicle was taken to the local dealer who diagnosed that the fuel injector and fuel sensor were faulty. The fuel injector and fuel sensor were replaced but the failure persisted. The cause of the failure was not yet determined. The manufacturer was not contacted. The failure mileage was approximately 24,000.

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.

When I push on the accelerator the car hesitates and then surges forward. I took the vehicle to the dealership where they recreated the problem however it was not throwing any codes. After examination they determined that the problem was turbo lag. I was advised to continue driving the car as usual until it throws a code or turbo fails. I believe that the vehicle randomly hesitating could leave you stranded in an intersection with oncoming traffic, and when if surges puts you at risk for a rear end collision. When I asked the service rep what will happen if the turbo fails, she said pull over and call on-star. I'll be traveling through the mountains for the holidays, it worries me that if the turbo fails I could be stuck on the side of the road in winter weather.

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.
