Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The car's fuel guage has been inaccurate since the initial purchase. It would always hang at around 50% and then drop to 5% within 10 miles. Thankfully, we are aware and just check the miles driven so we do not get stranded. Requested fix by dealership, they said there was nothing wrong. The recall for my car appeared and I asked for a fix, they said it's not available yet. It's been 6 months and there's still no fix for this. It would also have random computer issues such as screen shutdowns, and take to dealership warnings after the 1st 10k checkup. …”
