I spoke too soon. Wednesday July 30 we drove the car for an hour or so and parked it at 1 p.m. in our garage. At 6 p.m. we were planning to leave and the battery was dead again. Cadillac Roadside Assistance said that no dealers have technician service any more in the St. Louis metro area and all they could do is call someone to jump start the car or tow it to the dealer. I jumped it myself on Thursday morning, drove to the dealer and they're telling me once again that they can find nothing wrong with any systems or with the battery. This is very disturbing.

It isn't as if I've never worked on cars. In fact, I've worked on them since the 1960s, even changing out engines, and rebuilding transmissions. I just thought that a Cadillac service facility should be able to find and repair whatever was causing this problem. But after the last incident I decided to roll up my sleeves and go to work. I thought that I might find corrosion under a crimp hidden by heat-shrink so I decided to solder all the cables coming off the battery and going to the under seat and under hood fuse modules. In the process, what I found, was a bad ground at the floor under the back seat. The ground cable, which is common to all the electrical systems in the car, is attached to the floor with a plated screw, but in this case the screw mates with a threaded hole that had the same paint job as the outside of the car, and the ground terminal sits on the painted floor with no "star washer" under it to bite into the chassis. Checking from the battery end of the cable to ground points around the car gave ohmmeter readings all over the map. So I ground the paint off the chassis under the ground terminal and put it back together with a big star washer under the terminal. I'm hoping this will solve the problem.

My mother's 2007 DTS has not experieced any problems with it starting, but she has experieced it cutting off in traffic (!) at least 5 times. After the first 3 tim;es, the dealer kept it for 10 days only after my mother said she did not want it back - they did not find anything wrong, except that some codes were missing related to the brakes???? (GM even came to "investigate", but refused to talk to my mother!) They fixed the codes, then she took the care in about 3 months later for the regular oil/maintenace and to have them look at some vibrating that she was feeling in the front end, and they discovered that the brake pads were worn. They fixed them, but then she experieced the car cutting off while driving 2 more times. The dealer and GM have not resolved the problem and basically tried to make it sound like it is something my Mother is doing while driving??? My parents have been Cadillac owners for 50+ years, but this is the last one! To make matters worse, the salesman talked her into leasing the car and she has no options until the lease is up! So much for customer service!

Hello, I know the exact part that you will need to resolve your problem. It's called a Crankshaft sensor. I have a 2003 DTS and this was happening to me sporadically usually at stop lights or when I would come to a complete stop. Lindsey's Cadillac, which is the dealer in my area, could not find the problem. Fortunately a friend of mines had the same symptoms with his DTS and he visited a Caddy forum in which someone told him to get a Crankshaft sensor. I believe the part was roughly $60 bucks. I paid $70 or so in labor. Never had the issue since. I didn't even take it to the dealer to replace the part, I used a local Midas in the area that knew GM cars and they replaced it for nearly a fraction of what the dealer was charging. Good luck, and I am 100% sure this will resolve your Mom's DTS issue.

Thank you, Caddylvr. The car is in the shop right now - they still haven't found anything. I will pass on the info. Much thanks.

My 2008 Cad. DTS has a humming noise when the car is shut off. I suspect that it has something to do with the reomote outside mirrors. recently I see what appear to be hydraulic fluid staind near the mirror on the passenger side. Dealer is clueless.
#47 of 99 '08 DTS Performance Electrical Burn
Dec 06, 2008 (1:03 pm)
Here's a new one for you: Saw a streaming leak in my driveway just after pulling into the garage. Then noted a puddle under the car: Red, oily liquid. Called the dealer who had it towed in. The fluid was from the power steering. Per the maintenance write-up: A return line had a hole burned in it from contact with a battery cable. Wonder how many of the dead battery episodes are due to the battery grounding out to some part of the car.....
#48 of 99 Dead Battery
Mar 29, 2009 (8:56 am)
I have a Cadillac 2006 DTS. If I don't drove the
car for 7 days the batter dies. I have had 3 new batteries installed, numerous visits to the dealer and each time I get the same answer, "we checked everything and we don't find any problems". After reading all the the similar complaints on line how is it that GM can't come
up with a resolution. Plus the battery is located under the rear passenger seat. Brilliant
design. Is there any reason the tax payers should loan GM any money. They need to be allowed to fail and thus survival of the fitist

Your problems sound very familiar to mine. I have
an '06 DTS and went through the same episodes. I submitted my problems for arbitration under the lemon law, but GM went into bankruptcy. Now I am back where I started. GM needs to work on their QA
if they expect to survive.
