“In the cars digital instrument cluster have problem on the same model many of cars because I know many of friends that have same model car and I get problem so I go to the mechanic and the mechanic says it is a manufacturing problem on that same model have same problem I repair it twice and now it again appears it's also a safety concern because the problem is the light is completely go out completely blank so we are not able to see the vehicle speed vehicles fuel gas and vehicles other information that shows on digital cluster so if we drive in this condition we don't know how much speed is on my car right now”
“Randomly my instrument panel goes blank while in motion and can only be retrieved by hard turning the car off when stopped, you loose your speedometer, lights, and all until reset. Other issue with speedometer readings that are consistently off between 5-15mph with no fix, resolutions or repairs.”
“Trunk lock will not unlock or allow opening, back latch malfunctions, when car battery dies or car looses power《• you cannot open the trunk and access emergency tools/equipment and battery to jump car. •》You have to access by climbing through the front of the car if you are able-bodied too. There is no opening handle from the inside of the trunk to be let out, scariest and one of the most important major safety concerns, theres no emergency exit from inside vehicle. Water/snow/ice also falls down into the vehicle when opening hatchback, it slides inward from hood of car or slides back from rear windshield and door, causes water to be pooled up in my battery compartment.”

“I recently took my vehicle to the dealership because all the hazard lights on the dash came on. They diagnosed it as an issue with the inverter water pump and suggested that the engine was overheating, which was causing the hazard light to appear on the dashboard. So I had them replace that part and everything was fine. A week later, I went to drive to work and my entire dashboard was out. My radio, clock, blinkers, and brakes worked, but I could not see the speedometer, gas gauge, odometer or any other dashboard features. When I tried to restart the car, it wouldn't turn off. I tried several times and even got my husband to try. When we couldn't turn it off, I drove blindly straight to the dealership. They diagnosed the issue as being a problem with the combination meter.
