GAC: real reviews from owners - shortcomings, problems and weaknesses

Chinese brand GAC (Guangzhou Automobile Group) is actively conquering the Russian market, offering modern crossovers at competitive prices. Models like GAC GS8, GS3 or Aion V They are attracted by their stylish design, rich equipment and a guarantee of up to 7 years. But how reliable are these cars in real use? Should we believe the manufacturer’s promises or are typical “Chinese” problems hidden behind the beautiful cover?

We analyzed hundreds of owner reviews GAC 2022-2026, identified recurring complaints and systematized them by key components: engine, transmission, electronics and body. The article contains only verified information from real users, without marketing embellishment. If you are considering purchasing GAC used or new, this data will help you avoid unpleasant surprises.

Top 5 shortcomings of GAC according to owner reviews in 2026

Despite the progress of the Chinese auto industry, GAC “childhood diseases” remain, which manifest themselves already in the first months of operation. Here are the most common complaints:

• 🔥 Problems with automatic transmission: jerks when switching, delays in response to the gas pedal (especially on GS8 with 2.0T + 8AT).
• 💻 Multimedia glitches: spontaneous screen reboots, connection errors Apple CarPlay/Android Auto.
• 🔋 Weak battery: Discharge after 3-5 days of inactivity (typical for machines with Start-Stop).
• 🚗 Plastic creaks: already after 10–15 thousand km, extraneous sounds appear in the cabin (dashboard, doors).
• 🛠️ High cost of spare parts: original parts (for example, windshield wipers or lamps) cost 2–3 times more than analogues for Korean cars.

Interestingly, most of the complaints concern electronics and small items, and not critical breakdowns. For example, engines 2.0T (model 4B20) and 1.5T (model 4B15) owners praise it for its reliability if you follow the maintenance schedule. And here is the box 8AT from Aisin raises questions - its behavior strongly depends on the firmware.

GAC engines: service life, oil appetite and typical breakdowns

The most common motors in the line GAC - these are turbocharged petrol units 1.5T (4B15) and 2.0T (4B20). According to reviews, both engines run 200–250 thousand km without capital, but there are nuances:

• ⚠️ Oily appetite: 1.5T “eats” up to 1 liter of oil per 10 thousand km (the norm for a turbo engine, but requires monitoring).
• ❄️ Problems starting in cold weather: below −20°C difficulties are possible (especially on 2022 machines with the first firmware).
• 🔧 Crankshaft oil seal leak: appears after 80–100 thousand km (solved by replacement for 5–7 thousand rubles).

Owners GS8 with 2.0T note that the engine “wakes up” after 3-5 thousand km of running-in - vibrations at idle disappear, responsiveness improves. But 1.5T on GS3 often criticized for uneven operation at low speeds (the problem is partially solved by flashing the ECU).

Engine model	Typical problems	Repair cost (avg.)	Resource to capital
1.5T (4B15)	Oily appetite, vibrations at idle, oil seal leak	8–15 thousand rubles.	200–220 thousand km
2.0T (4B20)	Problems with starting in cold weather, turbine wear after 150 thousand km	20–40 thousand rubles.	250–300 thousand km
1.3T (hybrid, Aion V)	Battery overheating, recovery system errors	50–100 thousand rubles.	180–200 thousand km

⚠️ Attention: If your GAC with 1.5T started to "trouble" when cold, check the spark plugs - often the problem is in their low-quality analogues. Original candles (NGK 94206) last longer, but cost ~3 thousand rubles. per set.

Gearbox: why the GAC automatic transmission “kicks” and how to treat it

The main headache for owners GAC - this is 8-speed automatic transmission Aisin TF-80SN, which is installed on most models. Typical complaints:

• 🚘 Jerks when switching (especially from 1st to 2nd and from 3rd to 4th gear).
• ⏳ Reaction delays when pressing the gas pedal (lags up to 1–2 seconds).
• 🔄 Inadequate logic: The transmission may “think” when overtaking or climbing.

According to service technicians, the problem often lies in ECU firmware. After updating the software (free under warranty), automatic transmission performance improves by 70–80%. However, some owners complain that even after flashing the jerks remain - in this case, changing the oil in the box helps (original ATF DW-1).

Update the ECU firmware from an authorized dealer|Change the oil in the box (every 60 thousand km)|Check the oil level (must be between MIN and MAX)|Contact a service to diagnose solenoids-->

There are reviews on the forums about mechatronics breakdowns after 100–120 thousand km (repair cost - from 80 thousand rubles). To extend the life of the box, experts recommend:

1. Avoid aggressive acceleration to the floor.
2. Check the oil level regularly (every 10 thousand km).
3. Do not tow trailers heavier than 1 ton.

Electronics and multimedia: glitches that infuriate owners

Strength GAC - this is rich equipment even in basic trim levels. But, as reviews show, software filling is often raw. Here are the most common bugs:

• 📱 Spontaneous reboots head unit (especially on GS3 2023).
• 🔊 Sound distortion in the audio system (crackling, wheezing at volume >70%).
• 📡 Problems with Apple CarPlay: connection after 3–5 attempts, connection interruptions.
• 🔋 Battery low for 2–3 days of downtime (incorrect ECU sleep mode is to blame).

Many owners solve problems with multimedia independent flashing (files are posted on forums like GAC-Club.ru). However, this is risky - if you make a mistake, you can “brick” the system. Official dealers update the software for free, but this does not always help.

How to update GAC media yourself

1. Download the firmware for your model from a trusted source (for example, 4PDA).

2. Copy the file to a flash drive (FAT32, no more than 32 GB).

3. Insert the USB flash drive into the car’s USB port and go to Settings → Software Update.

4. Follow the instructions on the screen (do not turn off the ignition!).

⚠️ Risk: if there is a failure, you will have to go to the dealer to restore the system (cost ~10 thousand rubles).

Critical problem: on some GAC Aion V (electric crossover) owners are faced with a failure of the recovery system after a software update. This results in a reduction in power reserve of 15–20%. The solution is to roll back to the previous firmware version.

Body and interior: squeaks, corrosion and build quality

Externally GAC They look solid, but upon closer inspection, flaws are revealed:

• 🔊 Plastic creaks: already after 5-10 thousand km the dashboard, pillars and doors begin to creak.
• 🎨 Chromium Peeling: On door handles and moldings (typical for 2022 cars).
• 🚗 Threshold corrosion: appears after 1–2 winters (if not treated with anticorrosive).
• 🪟 Condensation in headlights: especially on GS8 with LED optics.

Owners share life hacks:

• Creaks are eliminated by processing plastic silicone grease (for example, Liqui Moly Silicon-Spray).
• Chrome is restored using metal cleaning pencil (costs ~500 rub.).
• Thresholds protect liquid anticorrosive (Dinitrol 479 or Tectyl).

According to reviews, paint quality at GAC average - scratches appear easily, but there is no deep corrosion. However, after an accident, problems arise with restoring the body: original parts come from China 2–3 months, and analogues often do not fit the fastenings.

Cost of Ownership: How Much It Costs to Maintain GAC in 2026

One of the key arguments in favor GAC - this is low cost of service compared to European brands. However, there are pitfalls:

Type of work	Cost (average in Russia)	Frequency	Notes
Maintenance (oil change + filters)	8–12 thousand rubles.	Every 10–15 thousand km	Original oil 5W-30 (~4 thousand rubles for 5 l)
Replacing brake pads (front)	12–18 thousand rubles.	Every 30–40 thousand km	Original pads are 2 times more expensive than analogues
Electronics diagnostics	3–5 thousand rubles.	When errors occur	Without guarantee - up to 10 thousand rubles.
Battery replacement	15–25 thousand rubles.	Every 3–4 years	Original battery 12V 70Ah

The main problem is shortage of spare parts. For example, the front bumper on GS8 in the original it costs ~50 thousand rubles, but you will have to wait 1–2 months for it. Analogues (for example, from Haval) may not fit the fastenings. As a result, even after a minor accident, the car remains idle for weeks.

⚠️ Attention: If you buy GAC with mileage, be sure to check the service history. Many dealers save on oil and filters by using cheap analogues. This leads to premature wear of the turbine (repair from 100 thousand rubles).

GAC vs competitors: comparison with Haval, Chery and Geely

To objectively evaluate GAC, compare it with other Chinese brands according to key parameters:

Parameter	GAC	Haval	Chery	Geely
Engine reliability	⭐⭐⭐⭐☆	⭐⭐⭐☆☆	⭐⭐⭐☆☆	⭐⭐⭐⭐☆
Automatic transmission quality	⭐⭐☆☆☆	⭐⭐⭐☆☆	⭐⭐☆☆☆	⭐⭐⭐⭐☆
Electronics	⭐⭐☆☆☆	⭐⭐⭐☆☆	⭐⭐☆☆☆	⭐⭐⭐⭐☆
Spare parts price	$$$	$$	$	$$$
Warranty	7 years	5 years	4 years	5 years

According to reviews, GAC loses Geely in the reliability of electronics, but outperforms Haval and Chery by engine life. Main advantage GAC - this is long warranty (7 years), which covers most common problems. However, in practice, dealers often attribute breakdowns to “misuse” and refuse to repair them under warranty.

FAQ: Answers to frequently asked questions about the GAC

❓ Is it worth buying GAC in 2026 or is it better to wait?

If you need new car with 7 year warranty and you are ready to put up with little things (creaks, electronic glitches), then GAC - a good option. However, if it is important to you trouble-free operation, it is better to consider Korean brands (Hyundai, Kia) or Geely with a more refined transmission.

If you buy a used one, take a car no older than 2023 (before restyling) and be sure to check the maintenance history.

❓ What oil should I pour into the 1.5T (4B15) engine?

Manufacturer recommends 5W-30 or 5W-40 according to standard API SN/GF-5. Optimal options:

• Original GAC G-Oil 5W-30 (article G052200M2).
• Analogues: Liqui Moly Top Tec 4200 5W-30 or Mobil 1 ESP 5W-30.

Oil fill volume: 4.2 l (with filter replacement). Replacement interval - every 10 thousand km (despite the stated 15 thousand km in the manual).

❓ How to eliminate automatic transmission jerking on GAC GS8?

Procedure:

1. Update the transmission ECU firmware at the dealer (free under warranty).
2. Change the automatic transmission oil (original ATF DW-1, volume - 8 l).
3. Check the oil level (should be between HOT MIN and HOT MAX at operating temperature).
4. If jerking persists, diagnose the solenoids (a common problem after 80 thousand km).

The cost of a comprehensive automatic transmission repair (if required) is from 120 thousand rubles.

❓ Why does the GAC battery drain quickly?

Main reasons:

• Incorrect system operation Start-Stop (often the firmware is to blame).
• Current leakage through multimedia (checked with a multimeter, the norm is up to 50 mA).
• Weak original battery (capacity 70Ah insufficient for frost).

Solutions:

• Disable Start-Stop button on the panel (if you don’t drive in the city).
• Install a larger capacity battery (for example, Varta Blue Dynamic 80Ah).
• Update multimedia software (removes current leaks).

❓ Where is it better to service GAC: at a dealer or in a third-party service?

Advantages of an official dealer:

• Work warranty (1 year).
• Original spare parts and oil.
• Free software updates.

Cons:

• 30–50% more expensive (for example, maintenance at a dealer costs 12 thousand rubles, in a third-party service - 7–8 thousand rubles).
• Long wait for appointments (sometimes up to 2 weeks).

Conclusion: it is better to do the first 3-5 maintenance at the dealer (to maintain the warranty), then you can go to a proven service with experience in working with GAC.
