What owners wrote

A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.

The brake lines are rusted from the rear sub Frame that was rusted And caused an accident. They told me the sub frame was the only item covered but that they could only bolt it and not weld if and then the exhaust and brake lines (rusted too bad to describe) weren’t covered and since I couldn’t afford it they only repaired the subframe and left the rest hanging ! My brakes failed on the way home. No one was injured but I can’t believe they let me go home with that condition!

August 2023 CrashInjury

Ignition switches inadvertently turn from "run" to "accessory" position while car is driven and I have to restart the car to keep going. I woke up to read in the newspaper today (2/28/2014) that there is a recall on the GM faulted ignition deaths and the same exact problem described is in my car and still exists in this vehicle. I love this car but it scares me. I told the local new car dealership on this and they said it would cost about $2,000.00 to fix it and I should wait till it gets worse before fixing it.
