Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“While I was driving, my sunroof on the top exploded. There was no rock impact, no external or internal impact. I called Lexus and they told me it’s not covered. The Lexus representative said to submit a claim with triple A cus it’ll be at least 5k to take out everything and replace it. They won’t fix it themselves.”
