“Recall exists related to a potential issue with the high-pressure fuel pump, which could lead to engine stalling and increase crash risk.

The last time I was pulling out on the main road and stop right there. I made a big traffic, and I was scared because I cannot start the car. The guy stops and help me to push out of the road, but we cannot push the vehicle unless someone is inside the car. …”

“The rear subframe got separated from chassis.

I ended up replacing both brake lines and did not think too much of it and now I see a lot of people complaining about both brake line corrosion and subframe separation or excessive rust, casing rear subframe to fail. …”

“I purchased the car late April. I drove the car for three or four days and started noticing a rattling coming the front right part of the car (passenger side.).

Meinke’s mechanic diagnosed it as a loose component involving the brake caliper. He informed me they were covering it under the warranty, & asked me to bring the car back on Wednesday as he was short staffed. I brought the car back on Wednesday, it was there all day. …”

“The fuel pump filter failed and myself and grandchildren became sickened by the fumes. Once the back seat was removed and inspected by an independent source you could see how the gas had leaked into this area. There was no warning lights or messages that had appeared. This problem could easily ignited a dangerous fire situation.”
