2003 BMW 325i Problems

Engine -- Verified

Valve cover gasket leaks are common after 60,000 miles. Symptoms will include oil drips under the vehicle and burning oil smell from the engine compartment.

Suspension & Steering -- Verified

Failure of the front control arm bracket bushings—often referred to as thrust rod bushings—is moderately common. One symptom is a clunk or jolt felt in the steering when braking.

Engine -- Verified

An engine coolant leak may develop from the expansion tank resulting in engine overheating. When a cooling system component fails the entire cooling system should be inspected. It is not uncommon to find additional component have failed or are leaking.
Overheating can cause severe engine damage. If the engine begins to overheat it is recommended to stop at the first available location and have your vehicle towed to a repair shop.

Heating & Air Conditioning -- Verified

The blower final stage fan resistor is known to fail. Symptoms are the heater fan speed varies regardless of the setting, the fan will not turn off when the car is switched off, or the fan will not switch on at all.

Suspension & Steering -- Verified

A fluid leak may develop from one or more power steering hose. When a leak is being repaired, it is not uncommon for multiple hoses to be replaced.

2003 BMW 325i Recalls (Recent)

Body, Interior & Misc., May 3, 2013

RepairPal Expert Overview:

Airbags use a chemical reaction contained in an inflator module to create the pressure necessary to inflate the bags when deployment is required. These vehicles are being recalled because the front passenger airbag inflator may produce excessive internal pressure when deployed. As a result, the inflator module could rupture, causing metal fragments to strike vehicle occupants. Dealers will inspect and replace any defective passenger front airbag inflator modules found.

Electrical & Lights, August 25, 2011

RepairPal Expert Overview:

Intermittent light operation reduces the ability to warn other motorists of the driver's intentions, increasing the risk of a crash. Dealers will repair the affected vehicles as necessary to correct this concern.

2003 BMW 325i Reviews

I have a 2003 325I ,with 90,000 miles. My aunt bought it new and had all the scheduled work done by dealer.She gave me the car with 39,000 miles. I have spent about 5,000.00 dollars in repair ,since i am not mechanical inclined,no repair is ever less than 500.Currently only one power window works,dealer wants 2500. to repair. The engine overheats if driven more than 10 miles. The car is beautiful inside and out,but just a nice looking pile of crap.If someone ever offers me a free BMW I will run the other way.

I bought my 2003 325i in April 2008 with 40K. Today with 165K, I have had to replace: 3 water pumps, 2 radiators, 2 cooling expansion tanks, one window regulator, 2 front bushings, 1 cooling fan, 1 gas pump, 1 alternator, 2 brake pads, and 1 battery . The cost of maintenance including oil changes, and repairs is close to $0.08/mile. Otherwise the car is a joy to drive, and it's very economical 25 MPG average on regular gas (Do not use premium). My last repair was caused because the cooling fan exploded and damaged the radiator, expansion tank, water pump, etc, and cut the hood ($600.00 for patching and painting). When I got the car I discovered it was a Demo (never, never get one), and a CPO, which wasn't very useful. I took the car to the dealer 6 straight times to fix a coolant leak, they couldn't. After my CPO warranty expired I had to replace my first water pump ($850).

I absolutely LOVE this car! Sure, it has every problem common to this year model, but I was expecting it. Repairs [can] be expensive - even outrageous - if you are not comfortable with DIY. An example: power steering pump went out (known issue) and the dealer wanted $1070 to fix. I bought an improved pump that addressed the problem for $350 and installed it in about 2 hours. This fix was even easier than a GM. Yes, known problems with relatively inexpensive and quick fixes IF you are remotely competent with tools. I love everything about the car - performance, style and even making repairs. It truly is the "Ultimate driving machine."

I have a light vibration that starts around 25 MPH the dramatically increases as I accelerate. The car pulls out into a smoot run around 33 MPH then no more problems. Feel nothing as I decrease the speen so I know that its in the drive line but I took a look underneath the car and my God the driveshaft is located under the exhaust under a fire wall so before I tear into it I'd like to have a little conformation that the U-joint connecting the transmission from the driveshaft is the culprit.
