Engine

12 reports
“Driving down the road and the engine shuts off. Yes its available upon request. I have reported it to my mechanic. The safety is me and others as this has happened 3 times in the past 2 weeks in the middle of traffic. My mechanic has been the only one to look at the car and doesnt know what is wrong. When the car shuts off the battery light comes on and the car said airbag system service required on 09/13/2026 but went off a few hrs later. The problems started on 09/02/2026”

Electrical system

9 reports1 crash1 related recall
“1. On hot/warm days when I start my vehicle it will run then die and give me the code for Mass air sensor which I replaced but it keeps doing it; the check engine will stay on for a while then turn off until it does it again. 2. When driving and I go over a speed bump the suspension grinds or does a hard squeaking noise. 3. The USB in the center console stops working at times or when move the charging cord it disconnects for a few seconds. 4. Internal lights work when they want to, I thought the bulbs where burnt out and replaced them but they still come on when they want to not everytime a door is opened.”

Service brakes

4 reports2 crashes
“WITHIN 10,000 MILES OF OWNING MY NEW CAR I NOTICED IT WOULD RANDOMLY STALL SOMETIMES AT THE STOP LIGHT OF AN INTERSECTION. IT DOESN'T TAKE LONG TO START BACK UP. OTHER TIMES MY CAR STRUGGLES TO START ALL TOGETHER. I'LL TURN THE KEY 2-3 TIMES BEFORE IT STARTS. SEVERAL MONTHS WENT BY WHERE THE ISSUE WAS NO LONGER PRESENT BUT OVER THE PAST MONTH IT STARTED AGAIN. LIKELY RELATED TO THE WHETHER NOW THAT WINTER IS NEAR. FINALLY MY EBRAKE HAS NEVER WORKED SINCE I BOUGHT THE CAR IN EARLY 2019 WITH 21K MILES.”
