Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The DC-DC converter went out in December. The vehicle has 53,000 miles on it, so it is just out of warranty. I live 100 miles from the nearest dealership so I had it towed to a local shop. I was originally told the part was on back order until Mid-February. I was told yesterday, they think it may not be available until May 2026. If this is such a big issue that they can not keep up with the part, why is this not a recall item?”
NHTSA complaint #11709388, filed 2026-01“DC/DC converter failed (January 2025) and is sitting at the dealership. My vehicle completely shut down while I was driving on the interstate. I had the same issue in April 2024 and was without my vehicle for nearly 2 months.”
NHTSA complaint #11712829, filed 2026-01“Our DC converter caused an electrical malfunction which is apparently such a big problem that our dealership can not get the necessary parts to fix the problem. We are being told we are number 21 in line.”
NHTSA complaint #11718002, filed 2026-02“DC DC converter failed while driving. Car shut down and rolled to a stop. Could jump start the car but would only work for 10 seconds or so to move it out of traffic. 1-2 month part delay.”
