Why does my Malibu Maxx lose power steering or show a wrong fuel gauge?

Short answer: On a 2004-2007 Malibu Maxx, heavy steering with chimes and warning lights is the well-known electric power steering problem. GM recalled many of these cars, so check your VIN first because the dealer fix is free. A fuel gauge that never reads full is usually the fuel level sender in the tank.

Symptom: The steering suddenly gets heavy with chimes and warning lights, the fuel gauge never reads full, the rear brakes wear out early, or the engine shuts off while driving.

What to check first

1. Run your VIN at nhtsa.gov/recalls for the power steering recalls before paying for anything.
2. Have the battery and cables load-tested. Weak voltage makes the steering assist drop out.
3. For a wrong fuel gauge, have the codes read. P0463 points to the fuel level sender.
4. Look at the rear brake pads and see if the caliper parking brake levers return all the way.
5. Take weight off your key ring so it can't pull the ignition out of RUN.

Likely causes

1. Electric power steering motor fault (recall). The Maxx uses an electric motor on the steering column instead of a fluid pump. When it acts up, steering suddenly gets heavy and the dash lights up. GM recalled many of these cars for it.
2. Weak battery or poor battery connections. The electric steering draws a lot of current. A tired battery or loose cable can make the steering assist drop out along with chimes and warning lights.
3. Fuel level sender in the tank. The sender is a float and sensor on the fuel pump. When it wears, the gauge stops reading full or reads wrong. One owner's shop found code P0463 and quoted $555.
4. Rear brake calipers not fully releasing. If the rear parking brake levers on the calipers don't return all the way, the rear pads drag and wear out long before the fronts.
5. Heavy key ring pulling the ignition switch. A heavy bunch of keys can bounce the ignition out of RUN on bumps, so the engine shuts off while driving.

What it usually costs

One owner was quoted $555 parts and labor for a fuel level sender. Recall work on the steering is free at the dealer. Owners didn't post other prices.

Is it safe to keep driving?

Losing power steering suddenly is dangerous, because the wheel becomes very hard to turn. Get the recall checked right away. A wrong fuel gauge is safe if you track miles and refill early.

DIY or shop?

Battery checks, key ring weight and rear brake pads are DIY jobs. The steering motor and fuel sender are shop jobs.

What owners report

• In Losing Power Steering On Inclines, 2005 Malibu Maxx on Car Talk, a 2005 Maxx owner said the dash chimed, every light came on and the steering got heavy while climbing a small hill. Members pointed out that 2004-2006 Maxx models are under a GM power steering recall and advised getting it done at the dealer for free.
• In Malibu Maxx fuel gauge never goes above 3/4 on Car Talk, a 2005 Maxx with 19,000 miles never showed more than 3/4 tank. Members suspected the float on the fuel pump assembly. The owner's shop later found code P0463, said the fuel sender was out of spec, and quoted $555 to replace it.
• In Malibu Maxx 2005 Rear Disc Brake Problem on Car Talk, a 2005 Maxx needed rear pads and rotors at 34,000 miles while the fronts were fine. The owner traced it to the rear caliper parking brake levers not returning fully, so the pads kept rubbing.
• In Malibu Maxx cutting out on Car Talk, a 2005 Maxx kept cutting out at random while driving, and the dealer found nothing. It turned out the owner's very heavy key ring was pulling the ignition switch off.

Quick tip

If the steering goes heavy with the dash lit up, don't spend money until you've run the VIN. That recall covers a lot of these cars.
