1995 Pontiac Bonneville from North America - Comments

Air compressor replaced after 55,000 miles.

Top intake leaked coolant into engine.

Resulted in replacing engine after 70,000 miles.

Plastic screw holders in rear lights broke.

Oil leaks.

This car handles well and I have always been very happy with my previous Pontiac.

This is the third one I have owned, but this one has given me more problems in two years than the others gave me in ten, and with less mileage.

I am 16 years old and have recently purchased a 95' Pontiac Bonneville. It runs very well and has only 78,500 miles on it. The previous owner had no problems with it, and I myself have had nothing to complain about. There have been no problems with the air compressor, the engine is in working order, and there have been no oil leaks. The only problem I have experienced is a small coolant leak. (which you noted) I'm not a car expert, and I don't pretend to be. However, I test-drove many cars, all in decent condition, and the 1995 Pontiac Bonneville was by far the best. I am very happy with my purchase, and there are very few cars I would trade it for.

I purchased my 1995 Pontiac Bonneville on the county auction 2 years ago, and at that time it had already 114000 miles on it. But I purchased it anyway because I liked the look and its general impression; it's a man's car, with the engine sound and the power and all the luxury. Anyway, it still runs great and smooth, although it leaks a lot, and has some phantom electrical problems. It started with the false readings of my instrument panel, the battery gauge, the oil gauge, and the fuel gauge. So I brought it to the shop, where they replaced the alternator and stabilizer bar, only the problem is still there and its gradually getting worse, my brand new battery died in less than a year, and I have problem re-starting the car on hot engine. The other shop checked the electrical system via computer and didn't find anything wrong with it, now I'm confused.

Has anybody else have similar problem? I honestly don't know what to do, I like the car a lot, but I'm afraid that one day I'll have to tow it to a junk yard or just donate it.

Well, I just bought a 1995 Pontiac Bonneville, and well it has been in my hands for exactly two days, and already has shut itself down. But by this I did find out why it is hard to start when it is hot. My intake, which is plastic, now who would use plastic? Steel and plastic do not blend well. But anyways, look at that, and get it checked. It is leaking into your head and burning off in the engine - not a big leak, but enough. After driving it, you will find out it is costly, as I have 800 dollars later Canadian that is to fix it, and it should be all like new again.

Well I guess that is the problem with buying an old car with 220,000 on it, but it runs so smooth and well other than that. Well I hope this helps you with your experience.

I have owned my 95 Bonneville for a short while. It was stalling on me and I took it to a friend of mine who owned a shop. He did several diagnostics on it and got no communication with the cars computer. It ended up needing a new main computer, which may explain the false readings of the gauges that some of you may have experienced. It also fixed the stallings and every other electronic problem I have run into except the cars radio deciding it wants to turn itself up as loud as it can go from time to time.

I got into an accident about a month ago in my "Bonnie" (that's what I call my Bonneville) and I had a new strut tower and knuckle installed. I didn't drive it much, I was mostly driving my other car, but I had a long trip to make and as any owner of a Bonneville will tell you, you want to take the "Bonnie" out on any road trip. So I packed up the Bonnie and went on a 250 mile trip, after arriving I was driving around town and made a hard left into a driveway (where I was going) and I herd a loud bang. I parked and checked out all 4 tires, but none were flat so I went inside and forgot about it.

Later that evening, I went to pick up some food, and after driving down the road several miles and merging onto the highway I noticed the wheel shaking from side to side, remembering the bang I herd before I stopped and checked all 4 tires again. All of them were fully inflated so I got back in and started off again. The shaking got worse, so I decided to just make it off the highway going no faster than 50 mph.

I got about another mile down the road when just before my exit I heard a louder bang and the front end of the car dropped to the ground. My Bonnie ground to a stop on the shoulder of the highway, and when I got out to see what had happened, I realised what happened. The studs on the front passenger side tire had sheered off and the wheel had come off all together. When the tire and rim came off they were fine, but they tore up the fender and I noticed coolant on the ground. Also the roater needs to be replaced (that's what I ground to a stop on). I'm angry cause that's the same side I just had worked on less than 400 miles earlier.

Other than that, I love driving my Bonnie, it's a great car... once I got the stallings and all the other electronic problems fixed by replacing the Cpu.

I have owned my 1995 Bonneville SLE Supercharged since early July 2005. I have since had to have the transmission rebuilt due to a differential pin that grounding into the housing and caused the differential to explode with only 139k (10/05), almost all the idler pulley's have went out on me, the AC compressor just started on fire (5/06) and there is a heavy grinding coming from the passenger front foot well area. I have spent over $300 just having it looked at (I've also replaced ALL motor and transmission mounts) and after talking to multiple other 1995 Bonneville owners I found that 6 out of 7 have the same problem, although none as bad as mine. The grinding has been happening since before I bought the car and when the trans went I thought that may be the problem. Just to be safe I had the trans shop check the cv axles and they found them to be in satisfactory condition. Still searching for the elusive culprit for this noise that can be felt.

Also have had to replace the transmission cooler due to it leaking transmission coolant where the lines come into it as there was major corroding taking place (5/06).

We've had our Bonneville since '96 with 20,000 miles. Since

then we have had the intake replaced (very lucky at the time

it didn't ruin the engine). It's had constant problems dying/not restarting when hot over the last 5 years. It's been difficult to diagnose because it's OBD 1. Finally

replaced the crank sensor which I think has finally cured

the problem. Still fighting the air bag light staying on and

blower fan switch only working on high. Overall has been

a good car.

I am a 1995 Bonneville owner. I have owned the vechile for about a year now and it drove great until the past 3-4 months now the transmissions going out and I know 4 other people who's transmission went out on them in the past year so I don't know what to do it has 233,000 miles should I put a new transmission in her or buy a new car?
