Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Our Gmc has experienced 3 exterior door handle failures. We paid to have the 1st broken handle repaired as it was not operable from the outside. This makes for a dangerous evacuation experience in the event of an emergency. We chose a non-dealer repair facility due to the cost of using a dealer. This repair has held up well. Since that initial repair 2 more exterior handles have become inoperable. It's only a matter of time before the 4th and final handle fails. This vehicle is no longer under warranty. However, it's only very lightly used and has less than 60k miles on it. …”
