“I see this affects many years and models. Its the security system thinking the car is being tampered with after a new battery is installed. This car wont start as many others. It gets juice to the fuel pump lights and dash. Jumped the fuse to the starter and cae turns over but wont start. Ot will lock you out. No dealers or mechanics know what this problem is. So we have no choice but to junk the car. This is ridiculous. I'm one po'd Cadillac owner!!!”

NHTSA complaint #11321533, filed 2020-04, 177,000 miles“I was told by city service queens new york that at long last that the recall part was ready to be installed and when I arrived the next morning appointment I was told that GM did not deliver the part. I'm at an in pass and very annoyed.”
NHTSA complaint #10643251, filed 2014-10, 60,000 miles“Nhtsa campaign number: 14v355000 GM is making a half-hearted repair by placing an insert into the key. I've four times requested they mail me the inserts. They refuse. I must bring in the car so the dealer can record the VIN or they won't get paid. I can't spend 2 hours traveling to a dealership and waiting for the key inserts. It's not a vehicle repair and GM doesn't need my vehicle. Just the keys! I have four keys in the hands of different family members. Gathering them and making a trip to the dealership is unreasonable. …”
NHTSA complaint #10780496, filed 2015-10, 52,000 miles“Got a flat tire. Stopped on a paved street and put tire jack under front right undercarriage as indicated it should be placed. I raised the jack to remove the flat and then had to raise it more to install the temp spare tire. The jack collapsed on the temp spare and the body of the car hit the pavement. I'm fortunate I did not have a foot under the car or that I wasn't putting the temp spare on the wheel when it fell down. The jack has a grove the fit into the car undercarriage and it was installed correctly but the jack collapsed from the weight of the car as I raised the jack. …”
