Air Bags
94 of the 216 complaints (43%) mention airbags and seat belts. Airbag and restraint issues are often tied to open safety recalls, which are repaired by the manufacturer at no cost to you. Check your VIN on NHTSA's recall lookup first, and we can help with related warning lights and diagnostics. See our auto repair page.
Electrical System
34 of the 216 complaints (15%) mention the electrical system. Electrical problems are made worse by desert heat, which ages batteries, cables and connectors. We test the battery, starter and charging system and trace faults to the actual part. See our battery replacement and starter & alternator repair pages.
Suspension
30 of the 216 complaints (13%) mention the suspension. Suspension wear shows up as clunks, pulling and uneven tires. We inspect shocks, struts, bushings and joints and align the car after repairs. See our suspension & alignment page.

Most Common Pontiac G8 Check Engine Codes
Owners often put the exact trouble code in their NHTSA complaint. These are the codes cited most often for the G8. The most-cited is B0081 (manufacturer-specific body code), mentioned in 12 complaints. Counts reflect complaints that name a code, not every car on the road.
| Code | What it means | Complaints citing it |
|---|---|---|
| B0081 | Manufacturer-specific body code The meaning of this code varies by make and model, so it needs to be looked up for your vehicle and tested. | 12 |
| U0170 | Network code A scan and test is needed to confirm what this code means for your vehicle. | 11 |
| B0012 | Manufacturer-specific body code The meaning of this code varies by make and model, so it needs to be looked up for your vehicle and tested. | 2 |
A code is a clue, not a diagnosis. The same code can have several causes, so we test before replacing parts. See our check engine light diagnostics, and read whether it is safe to drive with the check engine light on.

Keeping a Pontiac G8 Reliable in Phoenix
Arizona heat is the hardest test a Pontiac will face. Batteries, belts, hoses, tires and engine oil all wear faster here, and a G8 that spends its life in stop-and-go Valley traffic needs maintenance earlier than the owner's manual's normal schedule suggests.
Our recommendation for G8 owners: follow the severe-service schedule, test the battery before every summer, inspect brakes and tires twice a year, and have any warning light diagnosed instead of ignored. If you are shopping for a used Pontiac G8, a pre-purchase inspection shows what the paperwork does not.
