1990 Pontiac Bonneville LE 3800 LN3 from North America


Reliable to a fault


112,XXX - MAF sensor died.

116,XXX - Harmonic balancer replaced.

117,XXX - Cam shaft interrupter magnet failed.

122,226 - Ignition key switch fell apart.

122,258 - Starter replaced.

General Comments:

It's a great running car, has just needed a few new parts. It's comfortable, reliable and would trust it to take me anywhere. The camshaft magnet failed which results in extra cranking when starting and slight loss in fuel economy (26hwy vs 27hwy). Great winter car.

The first 3 items were an epidemic when these were new.

Once you got them addressed, all was well.

Oxygen sensor.

General Comments:

It's a great car, the 3800 V6 and THM440-T4 is a great drive train. All I've done is put in new spark plugs and an air filter. It starts right up no matter what the weather, and the trans shifts as smooth as butter. it handles good and is a great highway cruiser.

The only issues are the O2 sensor needs to be replaced and the fuel weeps a bit because it's starting to rust thru.

I hope to put many more miles on this tank.

My Bonneville is the Yoda of cars


Hard for me to explain, the thing where the spark plugs go, not the engine, was leaking green stuff.

General Comments:

This car is nothing short of amazing. I bought it at the price of 550. The body isn't so hot anymore, but it drives well. I drive it hard, I do 75 to 80 every time I get in it, and it knows how to get up.

I am very impressed how it hasn't had any major problems with it, the only thing was the transmission and the previous owner had it fixed. But other than that, it is a great car to have.

It preforms when it is supposed to, and you do it in comfort.

Ohh by the way, did I mention it's 18 years old! Like me! I must say that it does have a certain presence to it. Like it's one of these rare cars that demands some type of attention. Well done Pontiac.

WOW!! Congrats on your first car. It caught my eye because my first car was the same age as me too. I was 16 and so was it. That was a LONNNNG time ago!! I just turned 60!!

I love Pontiacs and have a mint 2001 Grand Am with slight modifications that makes it a real screamer for a basic compact. My family also has a 53-year-old Pontiac with over a quarter of a million miles. It's been restored and is now used basically for shows and parades. I hope you enjoy yours. The '90 Bonneville was a real tank. They'll last forever.

This car is a great, reliable car and cheap to maintain


So far nothing major has gone wrong with the car at all. When I got it, it needed an oil change and power steering fluid.

I had to replace the driver's side headlight due to a pheasant flying in front of me while driving. I thought the cost for the replacement part was reasonable. It gets 8-9 mpg more than my former truck did.

General Comments:

I recommend this vehicle to whomever likes the luxurious feel at low cost. I was really amazed at how much this car has to offer for extras: all the seat controls, the function control on the steering wheel, and the biggest surprise to me was the air compressor in the truck, I haven't had to use it yet so I don't even know if it works. All in all I am very happy with my decision to purchase this car.

1990 Pontiac Bonneville SE 3.8L V6 pre-series I from North America


Cannot go wrong for the price


Well to start off it squeaks pretty loud at freeway speeds.

My water pump went up, luckily it was a cheap replacement and I did the work myself so no labor costs.

I wouldn't say its gone wrong, but the power seat controls are in a less than ideal position, makes it kind of hard to find a comfortable seat position, because my legs, and the fold of my pant legs sometimes hit the controls when I enter or egress.

General Comments:

Motor has a lot of torque and you can still feel it in the seat of your pants.

Handles surprisingly well despite its weight.

Great highway cruiser, with lots of space inside and room for luggage.

V-6 is bulletproof.
