Example complaints

“My 2018 Suburban required over $400 worth of expenses to replace a valve and recharge the freon in the AC. Less than a week later it required a new condenser and another $1250 in repair. The condenser was recalled in 2015-2017 suburbans and it sounds to me like it should include the 2018 model year as well. I should not have to put more than $1650 in repairs for that into a vehicle that is less than three years old. I have a family of six including a nine month old and it is not safe in the summer heat to be driving them around as this is the only car we have that fits the entire family. …”

“My vehicle completely shuts off while driving. All of the components on the dash and even my steering wheel moves into the prestarted vehicle position. It has happened 3 times in the past week now. One particular instance, I was on the highway and thankfully it came back on immediately before completely stopping but shutting off while driving 65mph is so dangerous.”

“I bought this vehicle in January 2019 . I had to have the AC worked on in April 2021. I was advised that the year 2017 had a recall on the same is mine is having… now in 2024 my AC has to be fixed again for the same thing … this is not a cheap fix. It should be under a recall .. please if u can help in any way i would very much appreciate it.. thank u”

“No official incident has happened yet, but the brake assist kicks in, yet does not work until it's revving engine to over 4000rpm, which causes a sudden jerk and scary sounds from engine. I have had a few instances where the vehicle did not want to stop almost causing an accident, and these have happened without anything in the car other than my daughter who is 2 and myself. The most recent problem is a weird rattling sound while going uphill. …”

“On approximately December 23, 2022, I notice that the UV protection coating on the hood and roof of my SUV is no longer protecting these areas of my vehicle. Which I am now concerned could lead to rusting on my 2018 SUV. I reported this issue after seeing many complaints on the WEB for the same problem by vehicle owners. A Chevrolet dealer mechanic also informed me of customers voicing my concern about the UV-protecting coating issue. I'm worried this issue will continue and affect the painting of my entire vehicle.”
