Volvo 850 Common Problems: What To Know Before Buying
The Volvo 850 is one of those ’90s cars that has aged with grace. With its boxy looks, five-cylinder engine, and that classic Volvo build quality, it still has a solid fanbase today — especially the turbocharged T5 and R models. Whether you’re looking for a fun project, a cool daily driver, or just appreciate well-built cars with personality, the 850 ticks a lot of boxes. But like any older car, it has its quirks. So, if you’re thinking of buying one, or already own one, here’s a no-nonsense look at the most common Volvo 850 problems — and what to keep an eye on.
1. That ABS Light? Probably the Module
One of the first things you’ll probably notice on many 850s is that ABS light on the dash — and yep, it’s a known issue.
🧠 What’s going on?
It’s usually the ABS control module starting to fail. It’s common and can affect your speedometer or traction control too. The good news? It’s often repairable or swappable with a rebuilt unit — no need to panic.
2. Clunks and Knocks? It’s the Suspension Talking
If the 850 you’re looking at makes noises when you go over bumps or feels a bit loose in the corners, the suspension probably needs some love.
🛞 What to check:
- Control arm bushings
- Drop links
- Struts or top mounts
This is typical wear-and-tear stuff, especially on a car that’s pushing 25+ years. It’s fixable — and makes a huge difference once sorted.
3. Oil Leaks (Because It’s a Volvo from the ‘90s)
These five-cylinder engines are solid, but they’re not shy about marking their territory. A little oil seepage is expected, but there are some usual suspects to check.
🛢️ Look at:
- Valve cover gasket
- Oil cooler lines
- Rear main seal (this one’s a pain to fix)
A little leak? Not the end of the world. Big puddles and no record of repairs? Something to think about.
4. Automatic Gearbox Can Be Fussy
If the 850 you’re looking at is an auto, take it for a long test drive. These transmissions are generally okay if serviced, but they can get grumpy with age.
⚙️ Watch for:
- Harsh or delayed shifting
- Slipping under acceleration
- Burnt-smelling transmission fluid
Manuals tend to be more bulletproof, but a well-maintained auto can still hold up well.
5. Little Electrical Oddities
Let’s be honest — ’90s Volvo electrics weren’t exactly cutting-edge even when new. Expect a few weird glitches.
🔌 Common issues include:
- Windows that stop working for no reason
- Dash bulbs going out
- Central locking acting up
These aren’t deal-breakers. Often it’s a relay, fuse, or just tired wiring. If you’re handy with a multimeter, most fixes are pretty straightforward.
6. Cooling System Wear
Old plastic radiators and original hoses don’t last forever, and a neglected cooling system can mean overheating problems.
🌡️ Check for:
- Cracks in the radiator
- Leaky water pump
- Thermostat that’s stuck open or shut
A fresh radiator and some new hoses go a long way in keeping your 850 cool and happy.
7. PCV System Blockages
The PCV (Positive Crankcase Ventilation) system tends to clog up with age, especially if the car hasn’t had regular oil changes.
⚠️ What it causes:
- Oil leaks
- Dipstick popping out
- Engine whistling or running rough
A PCV refresh is a bit fiddly, but totally worth it for engine health — and to stop your car from leaving a trail of oil.
So, Is the Volvo 850 Reliable?
Yep — these cars are seriously tough, and if they’ve been looked after, they’ll keep going for hundreds of thousands of miles. The engines are great, parts are available, and the community around these cars is fantastic for support and DIY advice.
✅ Look for a car with decent service history
✅ Be ready to do some suspension or PCV maintenance
✅ Check for leaks, dodgy electrics, and how the gearbox feels
Final Thoughts
The Volvo 850 is one of those rare cars that combines character, comfort, and dependability. Yes, it’s getting on in years, but with a bit of love and attention, it can still be a brilliant daily or classic weekend toy. Know what to look for, and you’ll be driving a proper Swedish icon that still turns heads.
