Had issues with electrical in 2015 in which gas gauge and other gauges, speedometer were "bouncing". Auto repair determined it was the fuel pump and replaced it to the tune of $600. This year, while driving at highway speeds when car suddenly looses all power and turns off. Brought back to same repair shop who stated battery cables were loose and tightened them free of charge. Now 4-5 months later and same issue is occurring which happened 4 times today. Twice while making a hard turn. Terminals are completely tight. Earlier this year could not turn ignition key and tapped it with a hammer to get it to turn. I have been reading quite a bit about an ignition switch recall, but no mention of it by the dealer for two recall fixes this year regarding the ignition key and fob, and some cover on the engine.

Problem 1: driving near my home and vehicle quit on me. Gas gauge showed full but come to find out, I was out of gas. Good thing I wasn't traveling at a high rate of speed, like interstate driving. Problem 2: vehicle wouldn't start, I'm being told it is the passlock system. Security light has only come on 1 time. I never know when its going to start. Very worried when I travel by myself. These have happened at different times.

1.)cannot drive with the brights on because it will unexpectedly trigger all lights to fail and you will be driving blind in the complete pitch black night. 2.)the speedometer, gas gauge, and temp gauge haven't worked since about 75,000 miles. I purchased this car brand new and have had it serviced as needed. This is a factory defect, not something that was caused somehow by me. I think that it is ridiculous that I have to deal with these defects with my own money when I specifically purchased a brand new car so I didn't have to deal with problems of the vehicle that one would associate with a used vehicle. The brights issue could literally kill people, I'm sure it probably has.

My instrument panel for over 4years has intermittently stopped like the speedometer would say I was going 100mph while going 20mph or 0mph when going 45mph. I have reported to various auto shops and chevrolet dealership and was told that if not constant do not worry about it. Now the RPM are stuck at 1 rpms and the speedometer is intermittent and not sure my other gauges are correct??? I am so frustrated as gm states they will not fix and no recall yet I read everywhere that people have gotten in fixed or have the same problem. This should be a recall and per the info below gm is fully aware. The dealership wants me to pay $500 for a defect and I need help. Also per the info below it has to be under 70000 miles. Well I have reported it since 55000!!! I want my car fixed by gm but they are refusing. What do I do?

Well gmc I don't even know where to start. 1st my transmission is stalling and seems like it is having a hard time shifting from 2nd to3rd gear there for stalling consistently as soon as the cars RPM goes to 2 and before 3 I have taken it various times to get it fixed and has been very costly and still the problem exists. 2. The security light come on and locks the car from starting almost 3 to 4 times daily took it to get fixed they ended up replacing ignition switch ignition holder everything on the inside of ignition over 1000.00. 3 electrical problem that causes signal lights to not work and sensors are. All out of whack during the day lights are on at night they don't turn on the AC seems to b stuck on feet and face almost as if it was clogged.5.the front right wheel shaking n vibrates every time you go above 60mph or turning.6. The fuel system went out the fuel pump the fuel sensor the actual fuel gauge stopped working.7.the transmission line on the bottom popped off as I was on the freeway spraying transmission oil all over the place almost causing an accident. And the list goes on and on...

My speedometer, RPM, and gas gauges are inaccurate. I cannot tell how fast I am going, nor how much gas I have. Then ever since I bought my car, brand new, my transmission has been slipping, its an automatic. The dealer fixed it the 1st time, but now again, 90,000 miles later, its us starting to happen again.my radio has stopped working, no light or noise period. Please recall because I have read literally hundreds of posts of the same problem in the same car. I paid good money for my car, not for this. All if these problems are unsafe and I really hate for my 1 year old boy to ride in it. Please, please recall the car.

As I put the car in drive as reached about 15 MPH the cluster panel started to spin as if it had a mind of it's own. Since then I don't know how fast im going. I could be stopped at a light and it says im going 90. I could be in a neighborhood and im going faster then my gauges can read. I have no gas gauge. It reads a different amount any given minute. My car over heated on 12/18/2013 thanks to having a gauge read that my temperatures were fine. But really they weren't. It would be nice to know how fast im going. If my car is about to overheat. If I need gas. Long road trips are out of the question. But they shouldn't be I paid for this car. Only to have it fail at 26,000 miles. It wasn't covered by bumper to bumper as it took me more than 3 years to get to 26,000 miles. I don't want to be taking a curve too fast and crash my car because im not equipped with mandatory safety equipment to drive. Nothing on the cluster panel works.

What is wrong
On certain passenger vehicles equipped with 3800 v6 (l36) engines and certain delphi fuel pressure regulators, the regulators have a much higher than usual rate of fuel leaks. A leak can allow fuel to enter the intake manifold through a vacuum line. If the engine does not start when cranked, the fuel from the leaking regulator and a mistimed spark can cause a backfire.
Risk
The backfire can rupture the intake manifold. The rupture of the intake manifold can displace a fuel line, pulling an injector out of place, and causing a fuel leak and possible fire.
Remedy
Dealers will install new fuel pressure regulators with improved diaphragms. The recall will be conducted in phased mailings. Phase 1 began on june 30, 2004, and phase 2 began on september 30, 2004. Owners should contact buick at 1‑866‑608‑8080, oldsmobile at 1‑800‑630‑6537, or pontiac at 1‑800‑620‑7668.
